The HUS VM block module storage system supports the following high-
capacity features. See the Hitachi Unified Storage VM Block Module
Hardware User Guide for details.
• HDD (disk) drives with capacities of 300 GB, 600 GB, 900 GB and 3TB.
• SSD (flash) drives with capacities of 200 GB, 400 GB, and 800 GB.
• Flash module drives with a capacity of 1.6 TB each.
• Controls up to 16,384 logical volumes and up to 1,152 disk drives, and
provides a maximum physical disk capacity of approximately 3,383 TB
per storage system
Connectivity

The HUS VM block module storage system supports most major operating
systems, such as Microsoft Windows, Oracle Solaris, IBM AIX, Linux, HP-UX,
Novell Netware, SUSU Linux, Red Hat Linux, And VMware ESX Server. For
more complete information on the supported operating systems, go to:
http://www.hds.com/products/interoperability/index.htm . The system

The required features for the Storage Navigator computer include operating
system, available disk space, screen resolution, CD drive, network
connection, USB port, CPU, memory, browser, Flash, and Java environment.
These features are described in Chapter 1 of the Hitachi Storage Navigator

High reliability
The HUS VM block module storage system includes the following features
that make the system extremely reliable:
• The system supports RAID6 (6D+2P/14D+2P), RAID5 (3D+1P/7D+1P),
and RAID1 (2D+2D/4D+4D). See the Hitachi Unified Storage VM Block
Module Hardware User Guide for more information on RAID levels.
• All main system components are configured in redundant pairs. If one of
the components in a pair fails, the other component performs the
function alone until the failed component is replaced. Meanwhile, the
storage system continues normal operation.
• The HUS VM block module storage system is designed so that it cannot
lose data or configuration information if the power fails. This is explained
in Battery backup operations in the Hitachi Unified Storage VM Block
Module Hardware User Guide.
