Hitachi F350 - Chapter 1: Overview; Block Configuration; System Features

Chapter 1: Overview
The Hitachi Virtual Storage Platform F350 and VSP F370 are versatile, rack-mountable all-
ash arrays equipped exclusively with ash drives that can be scaled for various storage
capacity congurations. To deliver consistent low-latency host response times and high
IOPs performance across all host connection ports, conventional hard-disk drives are not
supported in the VSP Fx00 models.
The storage systems provide high performance operations by using multiple controllers
with high-speed processors, dual in-line cache memory modules (DIMMs), cache ash
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
conguration so that the storage system can remain operational if a component fails.
Adding and replacing components, along with rmware 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 congured 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.
Block configuration
A storage system congured for block-level storage provides the ability to access and
provision raw storage volumes using protocols such as Fibre Channel and iSCSI.
A block conguration consists of the following:
■
One multiple controller chassis with on-board drives
■
One or more optional drive trays
■
Optional service processor (SVP)
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 conguration, the
drive chassis oerings support SAS-interface solid-state drives.
