Hitachi Virtual Storage Platform F800 hardware overview


The Hitachi Virtual Storage Platform F800 is a modular, rack-mountable all-flash array storage system, with various fixed storage capacity configurations of FMD DC2 flash storage devices. To deliver consistent low latency host response times and highest IOP performance across all host connection ports, hard-disk drives are supported in an all-flash configuration.

The storage system contain dual controllers, each controller contains its own processor, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, fans and iSCSI and Fibre Channel I/O modules. Each controller also has an Ethernet connection for out-of-band management. If the data path through one controller fails, all data drives remain available to data hosts using a redundant data path through the other controller.

The storage system can be equipped with embedded network-attached storage (NAS) modules. The NAS modules provide file access through CIFS and NFS protocols and block access by using iSCSI protocols.

All storage system models allow defective drives to be replaced without the interruption of data availability to hosts. A hot spare drive can be configured to replace a failed drive automatically, securing the fault-tolerant integrity of the logical drives. Self-contained, hardware-based RAID logical drives provide maximum performance in compact external enclosures.

Essential hardware components are implemented with a redundant configuration so that the storage system can remain operational if a component fails. Adding and replacing components, along with firmware upgrades, can be conducted while the storage system is active.

Block configuration


A storage system configured for block-level storage provides the ability to access and provision raw storage volumes using protocols such as Fibre Channel and iSCSI.

A block configuration consists of the following:

  • Two controllers
  • One or more drive trays
  • One 1U service processor server (SVP)

Unified configuration


A unified configuration includes embedded NAS modules that support file system protocols such as CIFS and NFS and operate across a block-level setup using iSCSI or FC connections.

  • Two controllers
  • Two NAS modules for file operations and storage
  • One or more drive trays for block-level storage
  • One 1U block service processor server (SVP)

VSP F800 model


The VSP F800 is a highly reliable all-flash system that offers high storage capacity with full redundancy to better protect data and manage storage operations.

The storage system consists of a 4U enclosure that includes two controllers. Drives are supported using drive trays connected to the controllers.
