Introduction
The HP StorageWorks VA7000 Family arrays that support MPE/iX include the VA7100, VA7110 , and VA7410
arrays. Where sections are specific to a particular array, they are called out. If a section is not specifically
called out, it is common to all.

Overview
VA7100 Overview
The HP StorageWorks Virtual Array 7100 is a disk storage system that holds from 4 to 15 disk drives. The array
has scalable capacities from 72 GB to 270 GB (211 GB usable) with all 18-GB disk drives and from 144 GB to
540 GB (428 GB usable) with all 36-GB disk drives and from 292 GB to 1.1 TB with 73-GB disk drives.
Capacities and spindle speeds can also be mixed. The array requires a dual controller configuration to support
MPE/iX. At least one controller must be attached to a management station running the HP StorageWorks
Command View SDM software. Each controller has two DIMM slots available to hold NVRAM. The NVRAM is
used for read/write caching and for storing array memory maps.
The Virtual Array 7100 can operate in either RAID 1+0 mode or AutoRAID mode, which eliminates the
requirement for the system administrator to understand and configure RAID levels. AutoRAID dynamically
adapts to the system’s workload, optimizing performance and cost. Users will find configuration significantly
easier than other array products, since RAID levels don’t need to be configured or managed. The VA7100
supports one redundancy group, and all drives belong to that group. Using Virtual Storage Array (VSA)
technology, when configured in AutoRAID mode the array controller automatically selects RAID 1+0 (disk
striping and mirroring) or RAID 5DP (RAID 5 Double Parity) depending on the usage patterns of the data.
