Overview of Hitachi Virtual Storage Platform F900

The Hitachi Virtual Storage Platform F900 is a versatile modular, rack-mountable all-flash array storage system equipped with drive boxes, supporting flash module drives, scaled for various storage capacity configurations. To deliver consistent low latency host response times and highest IOP performance across all host connection ports, conventional hard-disk drives are not supported in an all-flash configuration.

The storage systems provide high performance operations by using multiple controllers with high-speed processors, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, fans and ports to connect iSCSI and Fibre Channel I/O modules. Each controller has an Ethernet connection for out-of-band management. If the data path through one controller fails, all data drives remain available to hosts using a redundant data path through the other controller.

For reliability, 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 and without interruption of data availability to the hosts. A hot spare drive can be configured to replace a failed data 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.

Child Topics

• 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.

• Features

  All storage systems are highly reliable, versatile, and able to scale its performance by adding more drive chassis and data drives. Depending on the system configuration, the drive chassis offerings support SAS-interface solid-state and flash module drives.
