Flexible Connectivity; High Reliability; High Flexibility - Hitachi G1000 Hardware Manual

○ In a drive intermix configuration, it can be configured up to 576 flash
module drives with a maximum physical capacity of 8.0 PB per storage
system.

Flexible connectivity

Operating system support
The storage system supports IBM
operating systems, including Microsoft Windows
IBM ®
information on supported operating systems, see
en_us/interoperability.html.
Host connectivity
The storage system supports connectivity to mainframe hosts via FICON
front-end directors and to open servers via Fibre Channel, iSCSI and Fibre
Channel over Ethernet (FCoE) front-end directors. The storage system can be
configured with a combination of all of these front-end directors to support
both mainframe hosts and open servers simultaneously.

High reliability

The storage system includes the following features to enhance reliability:
• Multiple RAID configurations: The system supports RAID6 (6D+2P and
14D+2P), RAID5 (3D+1P and 7D+1P), and RAID1 (2D+2D and 4D+4D).
• Duplicate hardware: Every module in the controller chassis and drive
chassis are configured in redundant pairs so that if any module fails, the
redundant module takes over until the failed component is replaced. The
redundant hardware includes power supplies, VSD pairs, cache path
controllers, front-end directors, back-end directors, and drives. If one of
these hardware components fails, the storage system continues normal
operation with zero data loss.
• Protection from power failures: The storage systems have dual-power
feeds. In the event of a partial power loss on one of the feeds, the system
operates normally on the alternate feed until full power is restored. In the
event of a full power loss, the cache backup modules keep the cache
contents active for 32 minutes while the system copies the system
configuration information and all data in the cache to a cache flash drive
(SSD).

High flexibility

The storage system is available in several configurations, from a small single
rack, diskless system to a large six-rack system that includes two controller
chassis, up to 2,304 SFF drives, up to 1,152 LFF drives, up to 384 SSD
drives, up to 576 flash module drives, and a total of 2 TB cache. The system
can be easily reconfigured for more storage capacity.
