HP 3000 Enterprise Virtual Array - Manual (Page 18)

• Virtualization technology, Vraid, enables data to be distributed from 8 to 240 disks to increase
disk spindle count far beyond traditional RAID sets. This virtualization method also optimizes
storage for the best performance of a specific configuration and application. The Enterprise
Virtual Array eliminates tedious management functions to provide the best performance
possible.
• 300 GB 10K RPM disks, increasing the maximum available capacity
• 250 GB disks
• Both online (normal, high-performance) and Fibre Attached Technology Adapted (FATA)
(lower-performance) drives.
NOTE:
Use of FATA drives require VCS v3.020. You cannot use FATA drives without having VCS v3.020
installed.
• EVA3000 (HSV100) single disk enclosure configuration (2C1D)
• Downgrading to an earlier version of VCS without reinitializing the array. This retains all data
and avoids time-consuming data restoration.
• State-of-the-art controller software:
• Improves performance, increases capacity, and allows for easy dynamic storage expansion.
• High-density packaging and support of more disks per controller pair:
• The EVA5000 offers:
• Up to 24 TB of storage in a single 41U or 42U rack.
• Up to 35 TB using 240 disks per controller pair.
• The EVA3000 offers:
• Up to 8 TB using 56 disks per controller pair.
• Up to 22 TB of storage in a single 42U rack.
• Vsnap - Virtually Capacity-Free Snapshot:
• Replicate data instantly by taking a logical picture of the data without reserving an equal
amount of capacity. This process saves significant disk space and improves disk efficiency.
Available with the optional Business Copy.
• Virtually Instantaneous Snapclone:
• Makes a complete copy of your data, which is accessible before the copy completes.
The copied data can be used as a test platform for application changes and additional
performance benchmarking. Available with the optional Business Copy EVA.
• Integrated configurations:
• Completely integrated configurations with a single part number, plus disk drives, VCS and
system platform software kits.
• Easy-to-use storage management tools:
• Software tools that allow you to manage larger SAN configurations with more servers and
more storage solutions.
• Continuous Access EVA
• Provides remote data replication functionality on the EVA.
Virtualization
Virtualization is used to simplify the creation, presentation, and administration of storage to multivendor
host servers in a Storage Area Network (SAN). Virtualization changes the way the storage administrator
interacts with storage—streamlining the work required to manage and implement the storage environment.
This section describes how virtualization affects storage configuration.
You do not need to make decisions about planning, creating, and configuring stripe-sets, mirror-sets, and
RAID-sets. The software now automates these decisions. The decisions are simplified to basic choices on
