Hitachi G1500 - Chapter 3: Hardware Architecture; System Architecture Overview

Chapter 3: Hardware architecture
The basic system architecture of a VSP G1000, VSP G1500, and VSP F1500 single
controller is includes virtual storage directors (microprocessors) are shared across the
cache, front-end directors (host adapters), and back-end directors (disk adapters),
providing processing power where and when it is needed, without latency or
interruption.
This architecture signicantly increases the I/O throughput, up to three times the speed
of the VSP system. The system pr
o
vides a highly gr
anular upgr
ade path, allowing the
addition of drives to the drive chassis, and components such as virtual storage directors
to the controller chassis as storage needs increase.
