Storage system hardware overview

The VSP G1x00 and VSP F1500 storage systems can be configured with one or two controller chassis and up to twelve drive chassis that contain the drives. A 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 controller rack contains the controller chassis and up to two drive chassis. Additional racks can contain an intermix of 16U SFF or LFF drive chassis and/or 8U flash drive chassis as well as one or two Hitachi NAS (HNAS) file system servers. When the controllers of a two-controller system are housed in separate racks, the two controller racks can be placed up to 100 meters apart. In addition, the drive racks attached to a controller rack can be placed up to 100 meters from the controller rack.

VSP G1x00 support three types of drives: SFF hard disk drives (HDDs) and solid-state drives (SSDs), LFF HDDs and SSDs, and flash module drives (FMDs), including the second-generation FMD DC2 drives. The drives are mounted in a chassis that is specific to each drive type. VSP G1x00 also support a diskless configuration (no drive chassis, all external storage).

The VSP F1500 all-flash array is equipped with advanced high-density FMDs, providing up to 4M IOPS and 40 PB of capacity for multi-workload consolidation.

A VSD may contain either an Intel Xeon 2.1 GHz or 2.3 GHz 8-core microprocessor. The VSDs must be installed in pairs and the VSDs control the front-end directors, back-end directors, PCI Express interface, local memory, and communication to the SVP. The VSDs are independent of the front-end directors and back-end directors, and can be shared across them.

Front-end directors

A front-end director (FED) is a pair of blades installed in the controller.

The front-end director connects the storage system to the host servers, processes channel commands from hosts, manages host access to the cache, and controls the transfer of data between the hosts and the controller cache.

The following FEDs are available:

  • iSCSI
  • Fibre Channel
  • FICON (shortwave and longwave)
  • Fibre Channel over Ethernet (FCoE)

The Fibre Channel FED can be configured with either shortwave or longwave host connectors. The FICON is configured with either longwave or shortwave connectors that match the wavelength of the mainframe ports.

The following figure shows the port LEDs of a FED, and the following table lists the description of the port LEDs.

NoteA storage system can be configured with a mixture of FED pairs thus providing a variety of port types.

See Site preparation for information about port configurations.

Fibre Channel host connectorsThe Fibre Channel FED uses a host connector which is an LC-type optical transceiver that converts electrical signals from the FED to light pulses that are supported by the fiber optic cables. Host connectors are either shortwave or longwave. Fibre Channel FEDs are configured with shortwave host connectors by default. Longwave host connectors are available and can be substituted as needed.

The following figure shows the SFP transceiver of a host connector.

Flexible front-end director installation

The maximum number of FEDs that can be installed in the controller depends on the number of VSD pairs and back-end directors (BED) that are also installed.

As shown in the following figure, the controller is built with 12 I/O slots, eight of which are dual-purpose. This provides a wide range of configuration flexibility.

NoteEach front-end director and back-end director consists of a set of two blades, as indicated by the numbers in the figure. A VSD pair, however, uses a single slot, but is sold and installed in pairs.

The following list describes the purpose of the slots.

  • Eight of the 12 I/O slots support different types of devices.
  • Slots 1C/2C and 1D/2D are reserved for the first two front-end directors.
  • Slots 1E/2E and 1F/2F support the installation of either front-end directors or VSDs.
  • Slots 1A/2A and 1B/2B support the installation of either back-end directors or VSDs.
GUID-2799698F-EBE2-4B1D-B62B-3C2011D9C23D-low.png

The following table shows the order of front-end director (FED) installation. If the storage system includes internal drives, the controller requires a minimum of a single pair of back-end directors and can be configured to support up to two back-end director pairs. A storage system that does not include any internal drives is referred to as a diskless configuration. The term standard describes a controller configured with a single back-end director, while high performance describes a controller configured with two back-end director pairss.

Back-end director

A back-end director (BED) is a pair of blades installed into the controller chassis and it controls the data transfer between the cache memory and internal drives of the storage system.

Hitachi offers the following BEDs:

  • Standard back-end director
  • Encrypting back-end director

The standard back-end director blades are each equipped with four 6-Gbps SAS ports and do not support encryption.

The encrypting back-end director (EBED) blades each provide four 6-Gbps SAS ports. When writing data to the internal drives of the system, the EBED encrypts the data. The encrypted data-at-rest is unencrypted by the EBED as it is read from the drive. The EBED is certified as FIPS 140-2 Level 2 compliant to meet the strict security standards of customers managing storage systems. A Hitachi Encryption License Key must be installed during installation in order to enable the encryption functionality of the EBED and an additional license key known as FIPS 140-2 Level 2 License Key must be installed for operating in compliance with the FIPS 140-2 Level 2 specification. For more information about the encrypting back-end directors and implementing a storage system with FIPS 140-2 Level 2 compliance, contact a Hitachi Vantara representative.

For more information about FIPS 140-2 criteria and certificate for VSP G1x00, see the following websites:

The hardware components used in the standard back-end director blades are different from the encrypting back-end director blades. A BED pair may not consist of one standard and one encrypting blade.

Flexible back-end director installation

Use the following guideline when installing standard and encrypting back-end directors (BED).

A maximum of two BEDs can be installed in both the primary controller chassis and secondary controller chassis for a total of four BEDs per system. Only one type of BEDs can be installed into a system. The standard and encrypting back-end directors cannot be mixed in the storage system. The maximum number of BED pairs that can be installed into a controller chassis will depend on the number of FEDs that will also be installed into the controller chassis.

A system without internal drives (also known as a diskless configuration) does not require the installation BEDs. However, the system must include one or more FED pairs to provide ports to connect to externally attached storage as well as to host systems.

For more information about configuration rules for FEDs and BEDs, see Flexible front-end director installation.

Drive chassis

The VSP G1x00 support three different drive chassis. The VSP F1500 only supports the FMD chassis. All components in the drive chassis are configured with redundant pairs to prevent system failure. While the storage system is in operation, all components in the drive chassis can be added or replaced. For detailed information about the drives in each chassis, see Storage system specifications.

Cache memory

The VSP G1000, VSP G1500, and VSP F1500 storage systems can be configured with 64 GB to 1 TB of cache memory per controller. The cache memory is installed in one or two cache path control adapters (CPA). A CPA feature consists of a pair of redundant blades that are installed and work together to provide cache and shared memory for the system. The following figure shows two CPAs (2-3, and 1-4).

Cache memory modules (DIMMs) are available in either 16 GB or 32 GB sizes. The minimum memory required per controller is 64 GB, either two 16 GB DIMMs or one 32 GB DIMM must be installed in each CPA blade. The memory modules in a system must all be the same size.

The following table shows minimum and maximum cache capacities per controller. The figures are doubled for a two-controller system.

Memory operation

The controller places all read and write data into the cache. The amount of fast-write data in cache is dynamically managed by the cache control algorithms to provide an optimum amount of read and write cache, depending on the workload read and write I/O characteristics.

Data protection

The VSP G1000, VSP G1500, and VSP F1500 storage systems protect the loss of data or configuration information stored in the cache when electrical power fails. The cache is kept active for up to 32 minutes by the cache backup batteries while the system configuration and data are copied to the cache flash memory in the cache backup modules. For more information, see Cache flash memory and Battery backup operations.

Cache capacity

The recommended amount of cache to install is determined by the RAID level, the number of drives installed in the system, and whether Hitachi Dynamic Provisioning (HDP), Hitachi Dynamic Tiering (HDT), Dynamic Cache Residency (DCR), and Universal Volume Manager (UVM) are applied. The recommended data cache capacity per Cache Logical Partition (CLPR) = (CLPR capacity) - (DCR Extent setting capacity per CLPR). When CLPR is not applied to DP/DT/DCR, install the recommended data cache capacity shown in the following table.

To configure a system for maximum performance, contact your authorized Hitachi Vantara representative. See Getting Help in the preface of this manual.

Shared memory

Shared memory holds storage system configuration information and it resides in the cache. The capacity of the shared memory + the capacity of the cache memory = the total capacity of the cache memory needed by the storage system.

The capacity overheads associated with the capacity saving function (data deduction) include capacity consumed by metadata and capacity consumed by garbage (invalid) data. For more information, see the Provisioning Guide for Open Systems. The recommendation is to use 0.2% of active data size as cache size (200 GB of cache for every 100 TB of pool capacity to be reduced).

The following table shows the shared memory capacity needed depending on the kind of software applications installed in the system.

Cache flash memory

The cache flash memory (CFM) is contained in the cache backup modules in the controller, along with the cache backup batteries. Similar to the cache memory, a CFM feature consists of a pair for redundancy purposes. The CFM backup the cache in case of power or component failure. The following figure shows two CPAs (2-3 and 1-4).

GUID-415D1F31-B251-482F-86A1-59B061212695-low.png

Cache flash memory operation

Each CFM blade connects directly to its corresponding CPA blade and backs up the data in that CPA blade if power fails. When data that is not stored on disk is written to the cache, it is written to one blade of the CPA and mirrored to the other. If one CFM fails, or one phase of the power fails, the other CFM backs up the mirrored data from its corresponding CPA blade, and no data is lost. In the unlikely event where a CFM has failed and a full power failure occurs, the other CFM backs up the mirrored data from the CPA without any loss of data.

Cache flash memory capacity

The recommended size of the installed cache flash memory depends on the size of the cache memory, and is automatically selected when defining the configuration for the system.

The following table shows CFM capacities per controller with both small and large cache memory backup assemblies.

Notes:

  1. SDD sizes must be the same in all CFM. Cache must be distributed evenly across CFMs and controllers.
NoteThe small CFM SSDs (128 GB) can be installed in the large cache backup, allowing for easier and less expensive upgrades.

Service Processor

The service processor (SVP) is a hardware component that performs modifications of settings, reports statistical information about device availability, and provides maintenance accessibility to the storage system.

The controller chassis is equipped with a primary and an optional secondary service processor. The primary SVP is active while the secondary SVP is duplicated and remains on active-standby in case of a failure. Employing a duplicate SVP configuration provides redundancy and prevents the loss of use of its monitoring function. If a failure occurs, the standby SVP is automatically switched into operation. The switching operation time is approximately three minutes.

The table lists the technical specifications of the service processor.
