Description

The utility model relates to the field of data storage systems and, in particular, to the field of multi-protocol data storage devices supporting file and block access protocols.

A multi-protocol data storage device is known that implements integrated support for file and block access protocols (RF patent No. 2302034). A data storage system is a computer with an information storage service operating on it, which is based on the organization of information on rewritable read-only memory devices, for example, memory blocks, tapes or disks. A storage system is typically installed in a storage area network (SAN) environment or in a network attached storage (NAS) environment. The data storage system (SHD) used in the NAS environment can be implemented as a file server having an operating system, which, in turn, supports a file system through which the logical organization of information in the form of a hierarchical structure of directories and files (for example, on disks). Each “disk” file can be a set of data structures, for example, blocks on a disk, configured to store information, for example, the file data itself. In turn, the directory may be a special format file that stores information about other files and directories.

Also known is an external data storage system (patent No. 2383952).

In general, storage consists of hard disks (HDDs), an input / output controller, and a combining system. Drives, as a rule, support "hot swapping", that is, they can be connected and disconnected on the fly, without turning off the drive. This makes it possible to replace a failed hard drive without any troubles for the user. The primary and backup drive power supplies have enhanced reliability and are also hot-swappable.

A diagram of a typical disk storage system with one controller is shown in Fig. 1 at http://ko.com.ua/sistemy_hraneniya_dannyh_nachalnogo_urovnya_14866?site=mobile and taken as a prototype.

The disk storage controller is its center. He is responsible for input / output of data within the system and to external channels, as well as for the organization of storage and access to information. Storage controllers typically use SCSI, Fiber Channel, or Ethernet to communicate with the outside world. Depending on the purpose of the system, the controllers can implement different logic of work and apply various data exchange protocols. They provide block-level data for user systems, like Winchesters, or file services via NFS, CIFS, and Network File System, Common Internet File System like file systems. Such a controller typically supports standard RAID levels to increase system performance and provide fault tolerance.

The absence of a general power supply in emergency situations leads to a complete shutdown of storage systems, and the lack of control of electricity consumption reduces the effectiveness of the distributed power supply network of the equipment.

The closest technical solution is the device described in http://ko.com.ua/sistemy_hraneniya_dannyh_nachalnogo_urovnya_14866?site=mobile - prototype.

This data storage device contains a controller, N HDD connected by inputs / outputs to the controller, and two power supplies.

The purpose of the utility model is remote monitoring of a storage device.

This goal is achieved by the fact that in a data storage system containing a controller, N HDD connected by inputs / outputs to the controller, and two power supplies, an additional cluster of 1U servers is introduced, the first input / output of which is connected to the first input / output of the controller, a switch, the second input / output of which is connected to the second input / output of a cluster of 1U servers, and the third input / output - to the second input / output of the controller; IP monitoring unit, the first input / output of which is connected to the first input / output of the switch; a power system comprising a microcontroller, read-only memory, random access memory, information input unit, information output unit, display unit, interconnected by an address and data bus; a remote monitoring and control unit, the first input / output of which is connected to the second input / output of the IP monitoring unit, the first output - with the third input of the information input unit, and the first input - with the second output of the information output unit; a load measuring unit, the first output of which is connected to the third input of the remote monitoring and control unit, and the second output - to the second input of the information input unit; a power control unit, the first input of which is connected to the first output of the information output unit; uninterruptible power supply, the first output of which is connected to the second input of the power control unit, the second output - with the first input of the information input unit, and the input - with the third output of the information output unit; a controlled relay unit, the input of which is connected to the second output of the remote monitoring and control unit; a block of switched power supplies as part of the first and second power supplies, the first input of which is connected to the output of the power control unit, the second input to the output of the controlled relay unit, and the output to the input of the load measurement unit; WIFI unit, the input / output of which is connected to the third input / output of the IP monitoring unit, the fourth input / output of which is connected to the IP network.

Comparison with the prototype shows that the inventive device is characterized by the presence of new units and their connections between them. Thus, the claimed device meets the criterion of "novelty."

A comparison of the proposed solution with other technical solutions shows that the listed elements used in the blocks are known, however, their introduction in this connection with the other elements leads to the solution of a new problem of uninterrupted power supply of the data storage system. This confirms the conformity of the technical solution to the criterion of "significant differences".

In FIG. 1 shows a general block diagram of the proposed device, which includes a data storage device I containing N hard drives (HDD) 1, controller 2, server cluster 1U 3, switch 4, power supply IV, IP monitoring unit II, Wi- Fi III, IP Network V.

In FIG. 2 shows a power supply system IV, consisting of a microcontroller IV-1, read-only memory device (ROM) IV-2, random access memory (RAM) IV-3, an information input unit IV-4, an information output unit IV-5, an indication unit IV -13, interconnected by bus address and data IV-6; IV-10 remote monitoring and control unit, IV-9 load measuring unit, IV-8 power control unit, IV-7 uninterruptible power supply unit, IV-11 controlled relay unit and IV-12 switched power supply unit.

In FIG. 3 shows an implementation of an IP monitoring unit II.

In FIG. 4 shows an implementation of a Wi-Fi III unit.

In FIG. 5 shows an implementation of a power control unit IV-8.

The device operates as follows.

1U servers 3 can be configured to work according to the client-server information model, which allows many client systems (clients) to access shared resources, for example, files stored in a file system. File sharing is a characteristic feature of a NAS (Network attached Storage) system, since this capability is determined by the semantic level of access to files and file systems inherent in such systems. Storage media in the NAS system, as a rule, are installed on a computer network, which includes many geographically distributed interconnected communication channels, such as Ethernet, which allow remote clients to access information (files) on a file server. Typically, clients interact with the file system by exchanging discrete frames or data packets over predefined protocols, such as TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol).

In the client-server model, the client may include an application that runs on a computer and "connects" to the file server via a computer network, for example, through a point-to-point communication channel, a shared local network, wide area network or virtual private network, deployed on the basis of a public network, for example, the Internet. NAS systems typically use file access protocols; this means that each client can request file server services by sending messages over the network to the file server using the file system protocol (in the form of packets), and the messages identify one or more files that are requested access, regardless of their specific location, for example, blocks in which data is stored on disk. Support for multiple file system protocols, such as CIFS (Common Internet File System), NFS (Network File System, Network File System) and DAFS (Direct Access File System, Direct Access File System), allows you to expand the functions of the file server for working with network clients.

Storage Area Networks (SANs) are designed to transfer massive blocks of data to storage, while NASs provide file-level access to data. By combining SAN + NAS, you can get a high degree of data integration, high-performance access and file sharing. Such systems are called unified storage - "unified storage systems."

The hard disks used in the storage system can be divided into two main types: HDD (Hard Disk Drive) and SSD (Solid State Drive, the so-called “solid-state drive”). That is, both the drive are hard.

Power System IV Operation

In the initial state, the switched power supply unit is disabled. If it is necessary to connect the BP1 power supply unit (block of switched power supplies IV-12), the command is sent via the LAN network to the remote control and control unit IV-10. In this case, the relay is turned on in the controlled relay block IV-11, the contacts of which connect the supply voltage output from BP1 to the elements of the data storage device I and signal its connection via the remote control and control unit IV-10. When BP1 is turned on, the load current is calculated in the IV-9 load measuring unit, the value of which is transmitted to the IV-10 remote monitoring and control unit, as well as through the IV-4 information input unit to the IV-1 microcontroller and then through the address and data bus IV- 6 and the IV-5 information output unit to the IV-10 remote monitoring and control unit, and then through the IP monitoring unit II via the V network to the controlling authority.

The software embedded in the memory of the microcontroller IV-1, provides the calculation of the current consumption of consumed electricity, similar to electricity meters. This information is also displayed for each power supply (BP1 and BP2) in the display unit IV-13, together with the status of the power supplies (BP1, BP2) (on / off).

All calculations are carried out in the microcontroller IV-1. A possible implementation of the power control unit IV-8 is shown in FIG. 5. A triac is used as a control element.

An integral part of the claimed device is an uninterruptible power supply (UPS) IV-7, which supports power supply of BP1 and BP2 in the event of a power failure in a centralized network. UPS IV-7 is also under control of block IV-10 through the following circuits: block IV-4 - microcontroller IV-1 - block IV-5 - block IV-10 - block IP monitoring II - IP network V. At the same time, the charge level is monitored batteries, their direct charging and signaling of UPS IV-7 operating modes.

The IV-9 load measuring unit can be performed using Hall effect current sensors, compensation type current sensors, or on the ACS712 microassembly.

The IV-10 remote monitoring and control unit is an active network device that transmits and processes signals based on network protocols (for example, TCP / IP protocols).

The IV-1 microcontroller is an INTEL 80C51 LSI family with a clock frequency of 12-14 MHz.

The read-only memory device (ROM) IV-2 is designed to store data memory (maximum current consumption of the data storage device, battery charge current of the UPS IV-7) and commands for the IV-1 microcontroller, and it is a standard 64 kB INTEL 27C512 family of integrated circuits.

Random access memory (RAM) IV-3 is designed to store information related to the operating mode of the system. RAM is connected to the system bus address and data IV-6 and is a standard LSI INTEL 6264 family with a capacity of 8 kbytes.

The information input / output blocks IV-4, IV-5 are designed to organize 8-bit input / output ports of logic level signals. They are connected to the system bus IV-6 and is a parallel bit register.

In addition, the proposed device uses an uninterruptible power supply (UPS) IV-7 with the addition of the battery and its charging unit to the main power supply. This ensures uninterrupted operation of the data storage device when the main supply voltage of 220 V.

Thus, the considered technical solution allows remote monitoring of the main parameters of the data storage device and ensure its uninterrupted operation.
