Product overview
The
Hitachi Virtual Storage Platform G400, G600 are modular, rack-
mountable, storage systems.
The storage systems have dual controllers that provide the interface to a data
host. Each controller contains its own processor, dual in-line cache memory
modules (DIMMs), cache flash memory (CFM), battery, and fans. Each
controller also has an Ethernet connection for out-of-band management using
Hitachi Device Manager - Storage Navigator. If the data path through one
controller fails, all hard drives remain available to data hosts using a
redundant data path through the other controller. The storage system allows
a defective controller to be replaced.
The Virtual Storage Platform G400, G600 can be equipped with NAS modules.
The NAS modules provide file access through CIFS, NFS and FTP protocols
and block access using iSCSI protocols in addition to the block access
provided directly by iSCSI and FC I/O modules.
All storage system models allow defective drives to be replaced without
interruption of data availability to host computers. A hot spare drive can be
configured to replace a failed drive automatically, securing the fault-tolerant
integrity of the logical drive. Self-contained, hardware-based RAID logical
drives provide maximum performance in compact external enclosures.
Key components are implemented with a redundant configuration, so that the
storage system can remain operational in the unlikely event that a
component should fail. Adding and replacing components, along with
firmware upgrades, can be conducted while the storage system is operating.
