Hitachi Virtual Storage Platform G200
hardware overview
The Hitachi Virtual Storage Platform G200 is a modular, rack-mountable storage array
that delivers high performance, high reliability, and flash-accelerated scalability.
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.
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 with onboard drives
■
One or more optional drive trays
■
Service processor server (SVP)
VSP G200 model
The VSP G200 is highly reliable storage system that offers high storage capacity with full
redundancy to better protect data and manage storage operations.
