Product summary
Hitachi Virtual Storage Platform G1000 is a unified storage system that
provides high performance, high availability, and reliability. VSP G1000 scales
to meet the demands of IT organizations’ ever-increasing workloads. When
combined with server virtualization, the mission-critical storage virtualization
of VSP G1000 supports a new breed of applications at cloud scale while
reducing complexity.
The following key features illustrate how VSP G1000 provides a Continuous
Cloud Infrastructure for the enterprise:
• Global storage virtualization enables an always-on infrastructure with
enterprise-wide scalability that provides a complete separation between
host and storage. The scalability is independent of connectivity, location,
storage system, or vendor. Remote data center replication support allows
provisioning and management of virtual storage machines up to 100
meters apart.
• Integrated active mirroring enables volume extensibility between systems
and across sites through the provisioning and management of active-active
volumes up to 100 km apart. Combined with remote data center
replication, this mirroring is an ideal solution for critical applications that
require zero recovery point and recovery time objectives. Active mirroring
is enabled by the Hitachi global-active device feature.
• Unified storage with enterprise scalability allows you to centrally manage
multivendor storage resources across all virtualized internal and external
storage pools, whether deployed for SAN, NAS, or object storage.
• Unified storage management software (Hitachi Command Suite) simplifies
administrative operations and streamlines basic management tasks.
• Hitachi Accelerated Flash storage offers a patented data center-class
design and rack-optimized form factor that delivers more than 600 TB per
system. It supports a sustained performance of 100,000 8K I/O operations
per second per device, with fast and consistent response time.
• Server virtualization integration with leading virtual server platforms
provides end-to-end visibility, from an individual virtual machine to the
storage logical unit, protecting large-scale multivendor environments:

configuration and data management operations by issuing commands to
enterprise storage systems. CCI for VSP G1000 provides command-line
access to the same provisioning and storage management operations that
are available in Hitachi Command Suite and Hitachi Device Manager -
Storage Navigator as well as in-system replication, remote replication, and
data protection operations. CCI commands can be used interactively or in
scripts to automate and standardize storage administration functions,
simplifying the job of the storage administrator and reducing
administration costs.
• Business Continuity Manager (BCM) provides centralized, enterprise-wide
management of Hitachi replication solutions for IBM® z/OS® mainframe
environments. Business Continuity Manager software uses a single
consistent interface based on familiar full-screen TSO/ISPF (Time Sharing
Option/Interactive System Productivity Facility) GUI panels. Business
Continuity Manager automates Hitachi Universal Replicator, Hitachi

About the VSP G1000 storage system
The VSP G1000 storage system contains new architecture, technology, and
several new features. These include an improved, seventh-generation
hierarchical star net architecture that is shown in the following illustration of
the VSP G1000 hardware architecture.
In this architecture, the virtual storage directors (microprocessors) are

shared across the cache, front-end directors (host adapters), and back-end
directors (disk adapters), providing processing power where and when it is
needed, without wait time or interruption. This significantly increases the I/O
throughput.
VSP G1000 provides a highly granular upgrade path, allowing the addition of
data drives to the drive chassis, and components such as virtual storage
directors to the controller chassis as storage and processing needs increase.
A VSP G1000 system configuration may range from a single controller with
no drives, to a dual-controller managing up to 2,304 drives with
homogeneous logic control, cache, front-end and back-end interfaces, all
mounted in standard Hitachi Data Systems 19-inch racks. You can use non-
Hitachi standard racks that meet the specifications listed in the Hitachi Virtual
Storage Platform G1000 Hardware Guide.
12 Hardware overview
Hardware components
A basic VSP G1000 storage system consists of a controller chassis and one or
more drive chassis that contain the drives. The system includes a controller
rack that contains a controller chassis, and may be either diskless (no drive
chassis) or may contain one or two drive chassis.
Up to two additional racks can contain an intermix of 16U SFF or LFF drive
chassis and/or 8U flash drive chassis. They can also contain one or two
Hitachi Network Attached Storage (HNAS) file system servers. The VSP
G1000 supports three types of drives: SFF HDDs or SSDs, LFF HDDs, and
flash module drives. The drives are mounted in a chassis that is specific to
each type of drive.
The controller chassis contains the control logic, processors, memory, and
interfaces to the drive chassis and the host servers. A drive chassis contains
drives, power supplies, and the interface circuitry that connects it to the
controller.
The following illustration shows a fully configured VSP G1000 system with
two controllers containing 8 virtual storage director pairs (128 CPU cores), 2
TB cache, and 12 16U drive chassis containing 2,304 SFF drives with a
storage capacity of 4.5 PB.
Controller chassis
The controller chassis includes the logical components, memory, SAS drive
interfaces, and host interfaces. The controller chassis is mounted at the
bottom of the rack. If a two-controller system has two service processors,
both are mounted in controller chassis #0. A controller chassis includes the
following maximum number of components:
• Two service processors or one service processor and one hub
• 1 TB cache memory
• Two cache backup assemblies, each comprising a set of two boxes that
back up the cache in case of power failure
• Two cache path control adapters (CPA), each comprising a pair of
redundant blades that host cache modules as well as providing the PCI-
Express path to distribute data among virtual storage director (VSD) pairs,
front-end directors and back-end directors. They mirror the data to
prevent data loss if one blade fails.
• Four virtual storage director (microprocessor) pairs
• Four redundant power supplies with cooling fans
• Six front-end directors (FEDs), each comprising a pair of redundant blades
• Two back-end directors (BEDs), each comprising a pair of redundant
blades
• Ten cooling fan assemblies
The following illustration shows the front and rear views of the controller
chassis. All components are installed symmetrically on the left and right sides
of the controller. The rear side of the controller includes 12 configurable I/O
slots. Four of the slots support either FEDs or BEDs, and four of the slots
support either FEDs or VSD pairs. Components can be added to these slots as
needed to increase performance or storage capacity, or to support more host
systems. Note that it is not possible to include the maximum number of
VSDs, FEDs, and BEDs, all at the same time.
Drive chassis
VSP G1000 supports three types of drives: SFF, LFF, and flash module drives.
Each drive type requires its own chassis.

LFF and SFF chassis

A single VSP G1000 controller supports a mix of up to six 16U SFF chassis or
up to six 16U LFF chassis. The actual number of SFF and LFF chassis that can
be installed depends on whether any flash drive chassis are installed, and
whether any HNAS servers, Ethernet switches, or Fibre Channel switches are
installed.
As shown in the following illustration, a 16U SFF chassis consists of eight 2U

drive trays. Each SFF drive tray can contain up to 24 vertically mounted SFF
HDD or SSD flash drives, for a total of 192 drives per chassis. Disk and SSD
drives can be combined within a tray or within an SFF drive chassis. A single
controller system supports up to 192 SFF SSDs.
A 16U LFF chassis consists of eight 2U drive trays. Each LFF drive tray can
contain up to 12 horizontally mounted LFF drives, for a total of 96 drives per
chassis.
The following illustration shows a fully configured LFF chassis containing 192
SFF drives, and a fully configured LFF chassis containing 96 LFF drives.
See the Hitachi Virtual Storage Platform G1000 Hardware Guide for more
information about the supported drives and chassis.
Flash chassis
An FMD (flash module drive) chassis contains a set of four 2U flash drive
trays as shown in the following illustration. Each tray can contain up to 12
horizontally mounted flash module drives.
The minimum number of flash module drives in a flash chassis is four, one in
each drive tray. Flash module drives can be added to an FMD chassis in
increments of four, eight, or 16, depending on the desired RAID
configuration.
A single VSP G1000 controller supports a maximum of two FMD chassis, each
containing up to 48 flash modules. The number of FMD chassis that can be
installed depends on how many SFF or LFF drive chassis are installed, and
whether any HNAS servers, Ethernet switches, or Fibre Channel switches are
installed. A two-controller system supports a maximum of four FMD chassis.
See the Hitachi Virtual Storage Platform G1000 Hardware Guide for more
information about the flash module drive and the FMD chassis.
Features
This section describes the main features of Virtual Storage Platform G1000.
The VSP G1000 storage system includes several state-of-the art advances in
hardware technology that improve reliability, serviceability, and access to
drives and other components when maintenance is needed. These include:
• Hitachi Accelerated Flash storage offers a patented data-center-class
design and rack-optimized form factor that delivers more than 600 TB per
system. It supports a sustained performance of 100,000 8K I/O per
second, per device, with low and consistent response time.
• The latest 2.5 in. and 3.5 in. 6 Gb/sec SAS drives support lower
power consumption and higher density per rack with up to 2,304 drives in
six 19-inch standard racks.
• Hitachi NAS Platform hardware accelerated network protocols
support up to 2 Gb/sec throughput for sequential workloads and up to 1.2
million NFS operations per second.
• Primary data deduplication is supported using Hitachi NAS hardware-
based SHA-256 calculation engines. They enable up to 90% capacity
savings while maintaining high performance.
• Efficient caching makes up to 2 TB global cache dynamically accessible
by all connected hosts and Hitachi NAS Platform nodes.
• The controller racks can be placed up to 100 meters apart, providing
maximum flexibility to optimize data center space usage and to provide
ease of access for operation and maintenance. Drive racks connected to
the controller racks must be installed next to the controller rack.
• High-speed 8-core CPUs in the virtual storage directors, expanded
cache memory (up to 2 TB per system), flexible installation, and increased
drive types and capacities.
• Nondisruptive migration is available as a service from Hitachi Data
Systems authorized service representatives.
The new system includes integrated data and storage management using
Hitachi Command Suite and Device Manager-Storage Navigator. These
provide unified management across all Hitachi storage systems and data
types. See Software overview on page 25 for more information.
External SAN storage virtualization extends the useful life of existing assets
by allowing legacy devices to transparently inherit new functionality from VSP
G1000 and SVOS. This capability eases migration and reduces costs and risk
when moving from legacy Hitachi or non-Hitachi storage systems. It supports
dynamic tiering of storage capacity (internal or external capacity) and
nondisruptive data migration between tiers and between vendors.
Scalability
The VSP G1000 storage system offers an entirely new type of scalable and
adaptable integrated active-active architecture that supports unified
management. It offers greater performance, reliability, and flexibility. It can
be configured in several ways as needed to meet performance and storage
requirements.
Scalable system performance
System performance can be optimized according to user needs, and can be

easily upgraded (in small or large increments) as storage needs increase. The
following table shows the supported configurations.
Number of
Number of VSD pairs/CPU cores1 Cache size2

• A small VSP G1000 system can include a single controller chassis and one
or two drive chassis or flash drive chassis, mounted in one rack.
• A mid-sized system can include one controller and a maximum of six LFF
or SFF drive chassis, mounted in up to three racks.
• For block systems, the maximum configuration is a two-controller version
of the mid-sized system with twelve 16U LFF/SFF drive chassis, mounted
in six racks.
• For unified file and block storage systems, the maximum configuration
varies, depending on how many HNAS servers and switches are installed.
In addition to the number of disk drives, the system can be configured with
disk drives of different capacities and speeds, varying numbers of front-end
directors (FEDs) and back-end directors (BEDs), as follows:
• A single controller supports a maximum of two BEDs, each comprising a
redundant pair of BED blades. In this configuration, the controller supports
a maximum of four FEDs, each comprising a redundant pair of FED blades.
• Cache memory capacity: see the table in "Scalable system performance."
• Disk drives with capacities of 300 GB, 600 GB, 900 GB, 1.2 TB, and 4 TB.
• SSD capacities of 400 GB and 800 GB.
• Flash module drive capacities of 1.6 TB and 3.2 TB.
• Channel ports: 80 for one module, 176 for two modules with at least one
BED installed.
High performance
The VSP G1000 storage system offers high performance that enables
consolidation and real-time applications, a wide range of storage and data
services, software, logical partitioning, along with simplified and unified data
replication across heterogeneous storage systems. Its large-scale, enterprise-
class virtualization layer, combined with Hitachi Dynamic Tiering and thin
provisioning software, allows you to consolidate internal and external storage
into a single pool.
Virtual Storage Platform G1000 includes several features that improve

performance:
• Disk drives with 7,200, 10,000, or 15,000 RPM
• Flash drives with ultra-high-speed response
• High-speed data transfer between the BED and HDDs at a rate of 6 Gb/sec
with the SAS interface
System performance is scalable and upgradable, as described in Scalability

on page 19.
High capacity
Virtual Storage Platform G1000 controls up to 65,280 logical volumes and up
to 2,304 disk drives, providing a maximum physical disk capacity of
approximately 4,511 TB per two-controller storage system.
Connectivity
OS support
The Virtual Storage Platform G1000 storage system supports most major
IBM® mainframe operating systems and open operating systems, including
Microsoft Windows®, Oracle Solaris®, IBM AIX®, UNIX®, Linux®, HP-UXTM,
OpenVMSTM, and VMware®. For more information on supported operating
systems, see http://www.hds.com/products/interoperability/index.html.
Host connectivity
VSP G1000 supports mainframe (Fibre Channel (FICON)), open (Fibre
Channel) host interfaces, or a combination of the two.
High reliability
The Virtual Storage Platform G1000 storage system includes the following
features that enhance reliability:
• Support for RAID6 (6D+2P/14D+2P), RAID5 (3D+1P/7D+1P), and RAID1
(2D+2D/4D+4D).
• All main system components (power supplies, cache memory, data drives,
microprocessors, and so on) are configured in redundant pairs. If one of
the components in a pair fails, the other component takes over until the
failed component is replaced. Meanwhile, the storage system continues
normal operation.
• The system preserves all data and configuration information in the event
of a power failure.
High flexibility
The VSP G1000 storage system is available in many configurations, from a
small, one-rack, diskless system, to a large, six-rack system that includes
two controller chassis, up to 2,304 SFF HDD drives or 1,152 LFF drives, up to
384 SSD drives, up to 192 flash module drives, and a total of 2 TB cache,
according to the storage needs. It can be easily reconfigured as storage
needs change.
The system supports both block-only and unified (block and file)
configurations in open and mainframe environments. The unified systems
contain Hitachi Network Attached Storage servers and switches in addition to
the block controller and storage drives.
VSP G1000 storage systems provide the foundation for matching application
requirements to different classes of storage and delivering critical services,
including:
• Business continuity services
• Content management services (search, indexing)
• Thin provisioning
• Dynamic Tiering
• High availability
• Security services
• I/O load balancing
• Data classification
• File management services
Nondisruptive service and upgrades

The Virtual Storage Platform G1000 storage system is designed so that
service and upgrades can be performed without interrupting normal
operations.
• Main components can be hot swapped (added, removed, or replaced
without disruption) during normal operation. The main components include
every module in the controller chassis and the drive chassis (such as
power supplies, cache, VSDs, SVPs, a hub, and drives) and interface
modules (such as front-end directors and back-end directors).
• A service processor (SVP) mounted on the controller chassis monitors the
running condition of the storage system. Connecting the SVP with a
service center allows authorized service personnel to maintain the system
remotely.
• The firmware (microcode) can be upgraded without disrupting normal
operation. The firmware is stored in shared memory (part of the cache
memory module) and transferred in a batch, reducing the number of
transfers from the SVP to the controller chassis over the LAN. Replacing
the firmware online is faster because the storage system uses two or more
processors at the same time.
• Nondisruptive data migration is available as a service from Hitachi Data
Systems authorized service representatives. Self-service nondisruptive
data migration is planned for a future release.
Economical and quiet

The three-speed fans in the controller and drive chassis are controlled
thermostatically. Sensors in the units measure the temperature of the
exhaust air and set the fan speed to the minimum necessary to maintain the
unit temperature in a preset range. When the system is not busy, it
generates less heat and fan speed is reduced, saving energy and reducing
the noise level.
When the storage system is in standby mode, the disk drives spin down and
the controller and drive chassis use significantly less power. For example, a
system that consumes 100 amps during normal operation uses only 70 amps
in standby mode.

Single point of management
Hitachi Command Suite (HCS) is an application-centric storage management
solution that simplifies administration of a common pool of multivendor
storage. The software offers comprehensive management, control, and
discovery for file, object, and block storage services, reducing complexity,
costs, and risk in the storage infrastructure.
The base HCS product consists of Hitachi Device Manager, which provides
centralized management of multiple Hitachi storage systems. By providing a
single console for managing complex storage environments, Device Manager
software unifies and simplifies storage management. Featuring an intuitive
GUI, Device Manager supports multiple management views for primary and
secondary storage, including physical, logical, host, and NAS and virtual
server for provisioning and storage pooling.
Note: Key functions of the previously separate Storage Navigator have been
integrated into HCS to enable a unified interface for storage management.
HCS comprises the following optional components, each of which is licensed

separately:
• Hitachi Tiered Storage Manager: Supports storage tiers of differing
performance characteristics so that volume data storage costs and
performance can be optimized.
• Hitachi Replication Manager: Adds remote replication capabilities and
supports backup and disaster recovery.
• Hitachi Tuning Manager: Supports optimizing the performance of
storage resources.
• Hitachi Compute Systems Manager: Supports centralized monitoring
and management of hosts, including rebooting and power management.

data
Thin provisioning
Hitachi Dynamic Provisioning (an integral part of HCS) provides the VSP
G1000 storage system with thin provisioning services. Thin provisioning gives
applications access to virtual storage capacity. Applications that access
virtual, thin provisioned volumes are automatically allocated physical disk
space by the storage system as they write data. Thin provisioning allows
volumes to use only the amount of physical space required and no more.
All thin provisioned volumes share a common pool of physical disk capacity.
Unused capacity in the pool is available to any application using thin
provisioned volumes. This eliminates the waste of over-allocated and
underutilized storage.
Dynamic Provisioning also simplifies storage provisioning and automates data

placement on disks for optimal performance. You do not need to
micromanage application storage allocations or perform complex, manual
performance tuning. In addition, you can add physical storage resources to
the thin provisioning pool at any time, without application downtime.
Dynamic Provisioning offers the following benefits:
Nondisruptive addition of physical disks

Actual storage capacity from the DP pool is assigned to a DP volume when
the data is written. Until then, a DP volume appears as a virtual LVI/LUN
volume with no actual storage capacity. Because the application sees only the
virtual capacity allocated to it, additional physical disk capacity can be
installed transparently when needed without interruption.
Improved performance
Dynamic Provisioning improves performance by avoiding contention and
performance bottlenecks. By evenly spreading out hundreds of users’ I/O
patterns over all available spindles, Dynamic Provisioning optimizes
aggregate throughput, generally delivering the best performance.
Reduced storage acquisition costs

Reduced acquisition costs extend to savings in space, power, and cooling
requirements.
The ability to define a volume as larger than a physical disk allows you to
plan for future storage needs during initial installation. You can purchase only
the physical disk capacity for your current needs, adding physical storage
incrementally over time.
Simplified replication planning

Because you can define the desired volume capacity without regard to the
physical disk capacity, for volumes of 4 TB and smaller, you do not need to
use LUSE for volume expansion. This also simplifies creating replication pairs.
Dynamic tiering
Hitachi Dynamic Tiering (HDT) is based on Hitachi Dynamic Provisioning. It
further simplifies tiered storage management by automating fine-grained,
page-based movement of data to the most appropriate storage media
according to workload and usage patterns. It automates management,
maximizes service levels, and minimizes storage costs. The following figure
shows the Edit LUN Paths dialog of HCS, which allows you to choose the
remote path for an HDT type volume.
Dynamic Tiering offers the following benefits:
Reduced storage costs

• Reduces media costs and drive counts through self-optimized use of
storage tiers
• Achieves space efficiency through thin provisioning
• Eliminates manual data classification
• Eliminates manual data movement between tiers
• Reduces operational overhead
• Reduces space, power, and cooling requirements
Improved performance
• Optimizes data placement automatically for performance using an I/O
rate-based heat index
• Gives SSD-class performance to information stored largely on less
expensive tiers by automatically moving the most accessed data to the
highest (SSD) tier
• Supports the highest efficiency and throughput through granular page-
based data movement
• Uses wide striping across the entire pool
Efficient administration
• Simplifies management of up to three storage tiers as a single volume
• Automatically moves the most active data to the highest performing tier
• Automatically adjusts to dynamic workloads and capacity requirements
• Moves pages up and down for optimal placement
• Significantly reduces administration time
Data replication
Hitachi Replication Manager provides management capabilities to configure,

manage, and monitor Hitachi replication products for local and remote sites.
Replication Manager supports open systems and mainframe environments
and provides support for multiple data centers and multiple storage systems
at each data center. It simplifies and optimizes configuration, operation, task
management, automation, and monitoring of the critical applications and
storage components of your replication infrastructure. The following figure
shows the Replication Manager interface.
Replication Manager offers the following benefits:
Centralized management of a replication environment

Replication Manager can be used to manage storage systems and hosts at
different sites. The status of copy pairs, the progress of copy operations, and
performance information (such as data transfer delays between copy pairs
and buffer usage when copying volumes) can be centrally managed from a
single console.
Integrated database backup management
Replication Manager supports creating backups of databases. Called
application replicas, these backups are managed as a series of secondary
volumes that are rotated on a scheduled basis. Replication Manager manages
the relationships between backup objects and their associated logical units
within storage devices, the relationships between primary and secondary
volumes, and the backup history. Replicas can be mounted and dumped to
tape using scripts executed through Replication Manager.
Visual representation of replication structures

Replication Manager provides a centralized workspace where you can visually
check the structure of copy pairs configured across multiple storage systems.
Host and storage system relationships and copy pair definitions can be
visualized using functional views. Copy pairs in complex configurations such
as multitarget configurations and cascade configurations can be viewed as
lists.
Monitoring and immediate notification of error information

Replication Manager provides capabilities to specify monitoring conditions for
designated copy pairs and sidefiles. Alerts can be automatically generated
when the conditions are satisfied. You can continue monitoring the system
even when not logged in to Replication Manager because alerts can be
reported in the form of email messages or SNMP traps. The status of
application replicas is tracked and reflected in summary form so that you
know to what extent the application databases are protected. These
monitoring features allow you to work out advance strategies to handle
potential problems such as the deterioration of transfer performance due to
insufficient network capacity or blocked pairs caused by buffer overflows.
Modification of replication structures

Replication Manager provides capabilities to configure additional copy pairs as
business operations expand and improve performance by expanding buffer
capacity for copying volumes. You can also change pair states manually after
error recovery. Using the wizards provided in the GUI, you can set up pairs
while visually keeping track of complex replication structures.
Monitoring and analyzing remote copy performance (write delay time)

When using Universal Replicator, you can check copy performance visually
and perform root cause analysis using the Replication tab of the Hitachi
Command Suite GUI.
Performance management
Hitachi Tuning Manager is a path-aware storage resource management
application that maps, monitors, and analyzes storage network resources
from the application to the storage device. It provides the end-to-end
visibility required to isolate and diagnose performance bottlenecks with a
focus on business applications, such as Oracle, Microsoft SQL Server,
Microsoft Exchange, and IBM® DB2®. The following figure shows the Tuning
Manager interface.
Tuning Manager offers the following benefits:

• Simplifies performance reporting and management of your storage
environment
• Improves service quality with accurate performance reporting
• Increases application availability through rapid problem identification and
isolation
• Reduces storage costs with proper forecasting and planning of required
storage resources
• Incorporates a REST-based API for extraction of performance and capacity
data
Data mobility
Hitachi Tiered Storage Manager provides the unique ability to migrate
volumes between heterogeneous tiers of storage, without affecting
application access to data. The software supports up to 64 simultaneous
migrations, using 64 processor threads, and it offers a single interface for all
data movement between storage virtualized by the VSP G1000 storage
system.
The following figure shows the Mobility tab of HCS, which is used to access
Hitachi Tiered Storage Manager.
Tiered Storage Manager offers the following benefits:
• Matches application price, performance, and availability needs to storage
attributes
• Controls the automated behavior of Dynamic Tiering through the use of
standard and custom policies and profiles. You can also proactively create
and pool different classes of storage for maximum efficiency and long-term
performance
• Manages storage resources according to the needs of specific business
applications, while supporting the ability to migrate data nondisruptively

High availability with global-active
device
Global-active device employs volume replication to provide a high-availability
environment for hosts across storage systems and sites. The purpose of
global-active device is to provide data protection and minimize data access
disruptions for host applications due to storage system or site failures.
Establishing a global-active device pair has the following benefits:

• Continuous I/O:
If a primary volume becomes unavailable, the host continues to
transparently access the secondary volume.
• Clustered failover:
You do not need to perform storage system tasks such as suspension or
resynchronization of a global-active device pair due to a host failure.
• Virtual machine integration:

If a virtual machine is creating a high load at one site, you can simply
move it to the other (and data migration is unnecessary).
How global-active device works

A global-active device pair consists of a primary data volume and a
synchronous, remote copy on a Hitachi Virtual Storage Platform G1000 (VSP
G1000) storage system. A virtual storage machine is set up in a secondary
VSP G1000 using the physical information from the primary system. The
global-active device primary and secondary volumes are also assigned the
same virtual LDEV number in the virtual storage machine. As a result, the
paired volumes are treated by the host as a single volume on a single storage
system (with both volumes receiving the same data from the host).
The following figure shows an example global-active device configuration.
High availability with global-active device 37

Global-active device (GAD) pair volumes are monitored by a quorum disk
(preferably located at third site). The quorum disk acts as a heartbeat for the
GAD pair; the primary and secondary storage systems access the quorum
disk periodically to check on the other storage system. In the event of a
communication or hardware failure, the quorum disk determines which
storage system is still accessible, allowing operations to continue without
interruption.
The SAN multipathing software on the host runs in an active-active

configuration. If the primary volume (P-VOL) or secondary volume (S-VOL)
cannot be accessed, host I/O is automatically redirected to an alternative
path. Native multipath software operates at campus distances using cross-
site paths (as shown in the previous diagram). At metro distances, Hitachi
Dynamic Link Manager (HDLM) offers increased performance using preferred
paths (shortest possible route).
Global-active device storage system configurations

A global-active device environment can be implemented in one site or across
two or three sites.
38 High availability with global-active device

Global-active device requires three storage systems: primary, secondary, and
an external system used for the quorum disk. The configuration can be set up
across three, two, or one site.
• In a three-site configuration (recommended), each storage system is

located at a separate site. This configuration provides maximum protection
against system or site failures.
• In a two-site configuration, both the primary storage system and the
quorum storage system are located at the primary site. This configuration
provides a moderate level of protection against system or site failures.
• In a one-site configuration (not shown), all storage systems are located at
the same site. This configuration protects against storage system failures
but not site-wide failures.

requirements, and setup, see:

Example 1: Enabling simple and efficient storage
provisioning and unified management with Command Suite
Today, financial institutions provide a wide array of services to their
customers. These services must support both structured data (online and
ATM transactions, such as withdrawing or depositing checks and cash) and
unstructured data (such as email messages, SMS text messages, customer
feedback, bank statements, and electronic forms). To meet the ever-
increasing need for customer access to the services, the institutions must
have a solution that meets the following needs:
• Ability to process customer transactions quickly and accurately. At the
same time, provide access to online reports (such as account statements)
and forms (such as for opening a new bank account or for applying for a
mortgage).
• Flexibility to accommodate structured and unstructured data, and ability to
access services no matter where the storage system resides.
• Centralized management of all storage repositories to reduce storage
management costs and total cost of ownership.
Overall, financial institutions require a platform with the breadth and

flexibility to provide services wherever, whenever, and however customers
need them.
Solution
Hitachi Command Suite (HCS) software consolidates block and file storage
arrays to unify the management of all types of data, and provides a single,
integrated view for all customers.
HCS natively discovers Hitachi storage systems, Hitachi NAS systems, and
Hitachi Data Ingestor file appliance-based systems, displaying the correlation
of VSP G1000 File Module system drives with back-end physical volumes and
VSP G1000 File Module storage pools.
42 Software management examples

HCS discovers and displays related file systems, mount points, and share
information for CIFS, and export information for NFS systems. It unifies
block, file, and content data across all Hitachi storage and manages all
virtualized heterogeneous storage assets.
HCS natively provisions storage to an HNAS cluster the same way as to a

physical or hypervisor server, such as the VMware ESX server. It creates and
manages file systems, CIFS shares, and NFS exports using the unified,
common GUI. Reaching across file, block, content, and application
environments, HCS improves business application availability and
performance, and expedites access to critical data.
Example 2: Ensuring optimal storage performance and

business application service levels with data analytics
Banks offer several incentives to its customers. One of them is online
banking, which customers have come to prefer. They see the need and
growing importance of creating an excellent experience for their online
customers. They must provide quick, 24/7 access to online banking services,
and must do so across the many devices and platforms used by customers.
Customers expect access to these services anytime and from anywhere. If
the service is not fast, not available 24/7, and not consistent, customer
loyalty can be negatively affected and result in bank account closures.
ATM machines provide yet another critical service to bank customers. ATM
transactions have become an essential component of the banking industry.
The problem with ATM machines is when they are not functioning.
Banks strive to keep their business-critical services available for customers,

but often find the following problems still exist:

• Lack of performance baselines or benchmarks to analyze response time for
online banking and ATM applications
• Insufficient root cause analysis (RCA) techniques that look deep into
application performance problems, and ineffective existing techniques
• Absence of real-time monitoring capability and analysis of all elements in
the customer environment
• No tools to help storage administrators analyze application performance or
to determine if the storage is at fault
• Lack of custom reporting capabilities to obtain detailed storage capacity
and performance metrics to gain insight into key storage system
performance indicators
• Uncertainty whether critical business applications are meeting required
storage service levels
Solution
Use Hitachi Command Suite Analytics to monitor performance and meet
storage service-level needs.
• To help banks determine how well their online banking service is
performing, they must know the current level of performance and
benchmark it against an industry best practice. Storage downtime affects
system availability for online transactions. One of the best ways to avoid
bottlenecks is through regular monitoring, system feedback, and on-
demand customizable reporting based on parameters defined by users.
The parameters can be based on storage or files, such as EVS, FS, and
VVOL utilization, and on capacity reporting, such as on tiers, users, and
groups. Instead of reacting to bottlenecks after they occur, administrators
can get alerts from HCS Analytics about potential bottlenecks before they
occur. Administrators can identify problem performance trends at an
earlier stage to avoid system downtime.

HCS Analytics performs end-to-end performance monitoring along the
application's entire data path to quickly determine if storage is the source
of application-performance degradation. With this monitoring information,
storage administrators can take appropriate measures to remove
upcoming bottlenecks and to improve storage (and ultimately application)
performance.
• To ensure that critical business applications are meeting required storage

service levels and comply with storage service-level requirements, storage
administrators can use HCS Analytics to accurately monitor application
storage levels and quickly resolve problems. Applications have varying
service-level objectives (SLO) based on their business criticality. For
important applications, such as online banking and ATM transactions,
storage administrators can use HCS Analytics to provide the applications
with appropriate storage resources in compliance with defined SLO
requirements.
Management software
To ensure business application performance and predictive growth, Hitachi
Command Suite Analytics provides all the necessary capabilities to find
storage resource trouble spots, identify the actual affected storage resources,
and help determine the root cause of problems. It also provides centralized
service-level management of mission-critical business applications.
HCS Analytics features Tuning Manager and Command Director:

• Hitachi Tuning Manager provides comprehensive storage performance
monitoring required to maximize both business application and Hitachi
storage system performance. It provides integrated performance analytics
that can quickly identify, isolate, and find possible causes of performance
bottlenecks. Within the HCS central management console, the integrated

analytics capabilities provide the necessary first step to quickly address
performance problems associated with Hitachi storage environments.
If additional performance details or diagnosis is required, Tuning Manager
includes a web-based interface to provide deeper performance monitoring
across a comprehensive range of performance and capacity metrics, with
historical trending and custom reporting capabilities.
• Hitachi Command Director defines key storage performance and capacity
objectives by business application. It features a global storage service-
level management dashboard to monitor compliance 24/7 and identify
applications at risk. It provides an analysis of application performance and
capacity (allocation and utilization) to properly define storage service
levels.
Command Director then monitors service levels and storage system health
and investigates service-level violations to quickly identify and resolve
potential bottlenecks. Command Director also features a new SLO profile
recommendation engine. Recommendations are generated automatically
based on historical performance data. Users can easily update profile
assignments for volumes at application, pool, and volume levels.
Example 3: Maximizing business application performance

and availability with data mobility
Customer service is a top priority for major commercial and retail banks.
They strive to maintain good relationships with, and retain current customers
as well as attract new ones. They would also like to achieve faster response
times for customer transactions involving personal banking or credit cards,
and for potential customers inquiring about their services.
In addition to ensuring the timeliness of critical transactions, banks must

provide customers with effective processing of mortgage applications from
inception to closing.
Banks must optimize the cost of maintaining data gathered from numerous
mortgage applications. While users can tolerate slightly slower response
times that are required for transactional systems, they are quickly frustrated
by consistently slow responses. In a fast-paced business, older and closed
mortgage applications lose business relevance quickly, so it does not make
sense to store them on fast storage. A lower tier of storage can be used to
achieve effective, long-term archiving of inactive data (such as closed or
inactive mortgage applications that companies maintain largely in response
to legal requirements).
Solution
A Hitachi Dynamic Tiering (HDT) pool is added to a VSP G1000 to support
mortgage applications. Using Hitachi Command Suite Mobility, a custom

policy is applied to the volumes in the HDT pool that supports the mortgage
applications.
The policy is set to ensure that infrequently or never accessed mortgage

applications are placed on the lowest cost storage, reducing the total cost of
ownership. Conversely, the newest and still-active mortgage applications are
promoted to the fastest tier and get the fastest response time.
Management software
To optimize data access and application Quality of Service, Hitachi Command
Suite Data Mobility software places data wherever and whenever it is needed.
HCS Data Mobility features Dynamic Tiering, Tiered Storage Manager, and the
file-tiering capabilities of the Hitachi Virtual Storage Platform G1000 system.
• Hitachi Dynamic Tiering automates data lifecycle management at a low
cost while delivering top-tier performance to the information most
frequently accessed by the business. HDT manages the tiering
dynamically. It monitors and manages space utilization at the page level
rather than at the file or dataset level. This means that only frequently
referenced parts of a file or dataset reside on the highest tier of storage,
minimizing the amount of tier 0 storage required for the highly referenced
data.
HDT identifies hot spots of frequent access and moves them to the highest
tier of storage to improve storage performance. It also moves less
frequently referenced pages to lower tiers of storage. All of this occurs
with complete transparency to the application.
• Hitachi Tiered Storage Manager (HTSM) proactively matches application
performance and availability needs to storage attributes for optimal
placement.
• Intelligent file tiering improves performance in file-sharing environments
by automatically separating metadata from user data, placing metadata on
the fastest storage tier for improved response times, while keeping user
data on less expensive storage tiers.
