Environmental specifications
The following table lists the environmental specifications of HP Workstations.
NOTE: Derate by one degree C (1.8 degrees F) for every 305 m (1,000 ft) altitude over 1,524 m (5,000 ft).
Non-operating:
NOTE: Values represent individual shock events and do not indicate repetitive shock events.
Environmental specifications 21
Ensuring proper ventilation
Proper ventilation for the system is important for workstation operation. Follow these guidelines:
● Operate the workstation on a sturdy, level surface.
● Provide at least 15.24 cm (6 inches) of clearance at the front and back of the workstation. (Workstation
models vary.)
● Ensure that the ambient air temperature falls within the environmental specifications listed in this
document.
NOTE: The ambient upper limit of 35°C (95°F) is only good up to 1524 m (5000 ft) elevation. There is a
1°C (33.8°F) per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m (10,000 ft), the
upper ambient air temperature limit is 30°C (86°F).
● For cabinet installation, ensure adequate cabinet ventilation and ensure that the ambient temperature
within the cabinet does not exceed specified limits.
● Never restrict the incoming or outgoing airflow of the workstation by blocking any vents or air intakes,
as shown in the following figure.
This section describes the tools and utilities that provide system management for the workstation.

Workstation security
This section provides information about providing system security through asset tracking, password security,
hard drive locking, and chassis locks.
Asset tracking
Asset tracking features provide data that can be managed using HP Systems Insight Manager (HP SIM), HP
Console Management Controller (CMC), or other systems-management applications.
Seamless, automatic integration between asset tracking features and these products enables you to choose
the management tool that is best suited to the environment and to leverage investments in existing tools.
HP also offers several solutions for controlling access to valuable components and information:
● Security features such as the Smart Cover Sensor (side access panel sensor) help prevent unauthorized
access to the data and to the internal components of the computer
● Capability for protecting valuable data assets by disabling parallel, serial, or USB ports, or by disabling
removable-media boot capability
● Memory Change and Side access panel sensor (Smart Cover Sensor) alerts, which can be forwarded to
system management applications to deliver proactive notification of tampering with a computer’s
internal components
The Smart Cover Sensor and cable lock are available as options on select systems.
You can manage security settings as follows:
● Locally, with Computer Setup (F10) Utility
● Remotely, with HP CMS or HP System Software Manager (SSM), which enable the secure, consistent
deployment and control of security settings from a simple command line utility
For more information about Computer Setup (F10) Utility, see Computer Setup (F10) Utility menu on page 27.
The following Computer Setup (F10) Utility features let you manage computer security.

WARNING! Enabling DriveLock can render a SATA hard drive permanently inaccessible if the master
password is lost or forgotten. No method exists to recover the password or access the data.
DriveLock has been implemented as an extension to Computer Setup (F10) Utility functions. It is only
available when hard drives that support the ATA security command set are detected. On HP computers, it is
not available when the SATA emulation mode is RAID.
DriveLock is for HP customers for whom data security is the paramount concern. For such customers, the
cost of a hard drive and the loss of the data stored on it is inconsequential when compared to the damage
that could result from unauthorized access to its contents.
To balance this level of security with the need to address the issue of a forgotten password, the HP
implementation of DriveLock employs a two-password security scheme. One password is intended to be set
and used by a system administrator, while the other is typically set and used by the user.
No "back door" can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely
used when the data contained on the hard drive is replicated on a corporate information system or is
regularly backed up.
If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not fit the previously
defined customer profile, this outcome might not be acceptable. For users who fit this profile, the outcome
might be a tolerable risk, given the nature of the data stored on the hard drive.
DriveLock applications
The most practical use of DriveLock is in a corporate environment. The system administrator would be
responsible for configuring the hard drive, which involves setting the DriveLock master password and a
temporary user password. If the system administrator forgets the user password or if the equipment is
passed on to another employee, the master password can be used to reset the user password and restore
access to the hard drive.
HP recommends that corporate system administrators who enable DriveLock also establish a corporate
policy for setting and maintaining master passwords. This precaution will prevent loss of information if an
employee sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is
inaccessible and must be replaced. Likewise, by not setting a master password, system administrators might
find themselves locked out of a hard drive and unable to perform routine checks for unauthorized software,
other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in
this category include personal users, or users who do not maintain sensitive data on their hard drives as a
common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords

Access to Computer Setup (F10) Utility and DriveLock can be restricted through the setup password. By
specifying a setup password and not giving it to users, system administrators can restrict users from
enabling DriveLock.
Using DriveLock
When hard drives that support the ATA security command set are detected, DriveLock appears under the
Security menu in the Computer Setup (F10) Utility menu. You are presented with options to set the master
password and to enable DriveLock. You must provide a user password to enable DriveLock. Because the
initial configuration of DriveLock is typically performed by a system administrator, a master password should
be set first.
HP encourages system administrators to set a master password whether they plan to enable DriveLock or
not. This gives the administrator the ability to modify DriveLock settings if the drive is locked in the future.
After the master password is set, the system administrator can enable DriveLock or leave it disabled.
If a locked hard drive is present, POST requires a password to unlock the device. If a power-on password is
set and it matches the device’s user password, POST does not prompt the user to re-enter the password.
Otherwise, the user is prompted to enter a DriveLock password.
For a cold start, use the master or user password. For a warm start, enter the same password used to unlock
the drive during the preceding cold start.
Users have two attempts to enter a correct password. During cold start, if neither attempt succeeds, POST
continues but the drive remains inaccessible. During a warm-start or restart from Windows, if neither
attempt succeeds, POST halts and the user is instructed to cycle power.
Enabling DriveLock
To enable and set the DriveLock user password:
1. Turn on or restart the computer.
2. As soon as the computer is turned on, repeatedly press the F10 key until Computer Setup (F10) Utility
starts.
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly
press F10 to access the utility.
3. Select Security and then select DriveLock Security.
4. For each DriveLock-capable drive, select the drive by pressing Enter.
5. Under Enable/Disable DriveLock options, select Enable, and then press Enter to enable DriveLock for
that drive.
6. Enter a new user password (1 to 32 characters long), and then press Enter to accept.
7. Enter the password again in the Enter New Password Again field. If you forget this password, the drive
is permanently disabled.
8. Select Main and then select Save Changes and Exit. Press Enter to accept the changes. After you press
Enter, the computer performs a cold start before invoking the DriveLock function.
When the computer starts, you are prompted to enter the DriveLock password for each DriveLock-
capable drive for which you have set a password. You have two attempts to enter the password
correctly. If the password is not entered correctly, the computer attempts to start anyway. However,
the boot process most likely fails because data from a locked drive cannot be accessed.
Password security
The power-on password prevents unauthorized access to applications or data when the computer is turned
on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10)
Utility and can also be used as an override to the power-on password. An administrator can enter the setup
password at the prompt for the power-on password and gain access to the computer.
You can establish a network-wide setup password to enable the system administrator to log in to all network
systems to perform maintenance without needing to know the power-on password.
Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer
when power is connected, unless you specify the password. When a power-on password is set, Computer
Setup (F10) Utility presents Password Options in the Security menu. The password options include Network
Server Mode and Password Prompt on Warm Boot.
When Network Server Mode is disabled, you must enter the password when the computer is turned on and
the key icon appears on the monitor. When Password Prompt on Warm Boot is enabled, you must enter the
password. The password must also be entered each time the computer is restarted. When Network Server
Mode is enabled, the password prompt is not presented during POST.
To enable Network Server Mode, you must set a power-on password under Advanced > Password Options.
This option enables the computer to start without requiring the power-on password, but the keyboard and
mouse are locked until you enter the password.
To establish a power-on password through the Computer (F10) menu:

Preventing ESD Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
equipment damage sensitivity. The following packaging and grounding precautions are necessary to prevent damage to
electric components and accessories:
● Transport products in static-safe containers such as tubes, bags, or boxes, to avoid hand contact.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● When handling or touching a sensitive component or assembly, ground yourself by touching the
chassis.
Personal grounding Use the following items to help prevent ESD damage:
methods and
equipment ● Wrist straps — These are flexible straps with a maximum of one megohm ± 10% resistance in the
ground cords. To provide a proper ground, wear the strap against bare skin. The ground cord must
be connected and fit snugly into the banana plug connector on the grounding mat or computer.
● Heel straps, toe straps, and boot straps — These can be used at standing computers and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use
them on both feet with a maximum of one megohm ± 10% resistance between the operator and
ground.

System RAM
HP supports different amounts of total RAM in various HP workstations, based on the number of hardware
DIMM slots and the capabilities of the system. The total memory supported for each configuration is listed in
the Hardware Support Matrix for HP Linux Workstations at http://www.hp.com/support/
linux_hardware_matrix.
Audio
All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced
Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions.
The audio hardware provides basic playback and recording features. The ability to simultaneously play audio
from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio
mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.13
and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP
workstations also provide audio functionality over HDMI. The signal can be passed through the DisplayPort
connector to a monitor with audio capabilities. The vendor driver must be installed. Such a configuration
Network cards
All HP workstations include one or two integrated network interface controllers. Some support optional NICs.
Most Linux distributions have drivers for these interfaces.
Hyper-Threading Technology
The Z Series Workstations support Hyper-Threading Technology (HTT), an Intel technology that improves
processor performance by enabling the processor to simultaneously perform multiple tasks. The operating
system treats an HTT-enabled processor as two virtual processors and shares the workload between them
when possible. This feature can be used only if the operating system support multiple processors and is
specifically optimized for HTT.
To enable HTT:
1. During startup, press F10 to enter Computer Setup (F10) Utility.
2. Select Advanced > Performance Options.
3. Set Intel Hyper-Threading Technology to Enable, and then press F10 to exit the menu.
4. Select Main > Save Changes and Exit.
5. Restart the system to enable HTT.
NOTE: On most recent Linux distributions (including RHEL 6, SLED 11, and updates to those streams), the
kernel automatically detects that HTT is enabled and works correctly.
Some settings for AMD graphics, including reconfiguration of the /etc/X11/xorg.conf file, can be
accomplished through the many options provided by the following command:
/usr/bin/aticonfig
Information can be found in these directories after the driver is installed:
/opt/hp/ati
/usr/share/ati
/usr/share/doc/fglrx
If the automatic init script attempts to rebuild the kernel module, the name of the log file is /var/log/fglrx-
build.log.
NOTE: This section applies to internal workstation configurations that do not use add-in cards and external
enclosures.
Hard Drives
RAID hard drive maximum and associated storage controller options 105
Supported RAID configurations
All workstation platforms have the following controllers:
● LSI 2308 controllers — HP Z840 Workstations
● LSI 9217-4i4e controllers — HP Z440 and Z640 Workstations (optional)
● LSI 9270-8i controllers — HP Z440, Z640, and Z840 Workstations (optional)
The following RAID configurations are supported:
● Loses all data if any disk in the array fails. ● LSI 9270-8i
Mirrored disk array ● Provides 100% redundancy: all data from one drive ● LSI 2308
is duplicated on a second drive.
● LSI 9217-4i4e
● Recovers from a single-drive failure.
● LSI 9270-8i
● Serves as a good entry-level redundant system.
Striped disk array with ● Provides fault tolerance and I/O performance ● LSI 9270-8i
distributed parity improvement, especially for write-biased
applications.
● Uses several drives to stripe data, then copies the ● LSI 9270-8i
striped drives to provide redundancy.
NOTE: These instructions apply to Windows-based systems. They also apply to Linux distributions that
include the isci kernel driver support for the RSTe technology. This driver is included on recent releases of
most upstream and enterprise distributions, and may be available for addition to some previous releases. If
this driver is not available in the distribution, or is not applicable to the platform (e.g., the RST controller), the
Software RAID solution is recommended.
You can create a SATA RAID array that contains up to the maximum number of internal SATA hard drives and
eSATA drives (if you use an optional eSATA bulkhead cable) supported on your workstation.
Two or more hard drives must be attached to a controller (sSATA) for that controller's option ROM to run. If
two or more drives are on each controller, a unique option ROM executes for each controller.
The Intel SATA AHCI option ROM configuration utilities run when you select RAID+AHCI for the SATA
emulation mode.
NOTE: The option ROM displays once for each controller. Following the prompt, select Ctrl+l to choose the
controller.
1. Press Ctrl+l when prompted to enter the Intel Rapid Storage Technology enterprise utility (RSTe). Use
the arrow keys and the space bar to navigate and select options.
NOTE: If only one hard drive is attached, the utility does not open.

Performance considerations
Disk I/O bandwidth is typically limited by the system bus speeds, the disk controller, and the disks
themselves. The balance of these hardware limitations, as affected by the software configuration,
determines the location of the any bottleneck is in the system.
Several RAID levels offer improved performance relative to stand-alone disk performance. If disk throughput
is restricted because of a single disk controller, RAID can probably do little to improve performance until
another controller is added. Conversely, if raw disk performance is the bottleneck, a tuned software RAID
solution can dramatically improve the throughput. The slower disk performance is, relative to the rest of the
system, the better RAID performance will scale, because the slowest piece of the performance pipeline is
being directly addressed by moving to RAID.

HP confirms that Intel-based Z440 personal workstation contains DDR RAM volatile memory (memory
amount depends on the customer configuration). In addition, the motherboard in the condition originally
shipped without subsequent modification or the addition or installation of any applications, features, or
functionality, contain the following nonvolatile memory: PCH Real Time Clock (RTC) battery backed-up
configuration memory (256 Bytes), Super I/O battery backed-up configuration memory (16 Bytes), masked
keyboard ROM (2K Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128
Bytes programmable), TPM module (2.35 kB), and Serial Flash IC for System BIOS (128M Bits).
The volatile memory is cleared by removing power from the system for greater than 30 seconds. The
nonvolatile memory on the motherboard is restored by following the steps below:
1. If TPM Ownership has been taken enter F10 setup.
2. Navigate to the Security tab.
3. Select TPM Embedded Security > TPM Clear > Clear.
4. Save and exit BIOS.
5. Press F1 when prompted to accept the clearing of the TPM nonvolatile memory.
6. Download the latest BIOS for this system and operating system off of the HP website.
7. Follow the instructions on the website to flash the BIOS. This will clear all settings and passwords
related to the BIOS.
8. Power down the system and remove the AC power cord. The RTC and Super I/O battery backed-up
memory is cleared by removing the battery found on the motherboard, allowing the board to sit for
greater than 60 seconds, and then replacing the battery.
The DIMM SPD EEPROM is not readily available to the user, however there appear to be tools publicly
available to read and write this part. To eliminate the possibility that it could contain sensitive information,
remove the DIMMs or use one of these tools.

functionality, contain the following nonvolatile memory: PCH Real Time Clock (RTC) battery backed-up
configuration memory (256 Bytes), Super I/O battery backed-up configuration memory (16 Bytes), SAS
FLASH memory (32Mbits) and an EEPROM (64K Bits), masked keyboard ROM (2K Bytes), secondary LOM Flash
(4 Mbits), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes
programmable), TPM module (2.35 kB), and Serial Flash IC for System BIOS (128M Bits).

8. Power down the system and remove the AC power cord. The RTC, Super I/O battery backed-up memory
and LSI 2308 SAS controller battery backed memory is cleared by removing the battery found on the
motherboard, allowing the board to sit for greater than 60 seconds, and then replacing the battery.
The secondary LOM Flash is inaccessible to the user via any publicly available tools. There are programs used
by HP in manufacturing and R&D that allow access, but these are not available outside of HP. The embedded
LSI 2308 SAS controller flash ROM can be read, written, and erased via a firmware and BIOS utility
SASFLASH.exe available in the latest soft pack release on the HP website. The embedded LSI 2308 SAS
controller battery backed memory can be erased following the instructions stated above in step 8. The DIMM
SPD EEPROM is not readily available to the user, however there appear to be tools publicly available to read
and write this part. To eliminate the possibility that it could contain sensitive information, remove the DIMMs
or use one of these tools.
