Instruction Manual

• 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 specificconfiguration 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
•250GBdisks
• Both online (normal, high-performance) and Fibre Attached Technology Adapted (FATA)
(lower-performance) drives.
NOTE:
Use of FATA drives require VCS v3.020. Y ou cannot use F A TA 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:
• Upto24TBofstorageinasingle41Uor42Urack.
• Upto35TBusing240diskspercontrollerpair.
• The EVA3000 offers:
• Up to 8 TB using 56 disks per controller pair.
• Upto22TBofstorageinasingle42Urack.
• 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 con figurations with more servers and
more storage solutions.
• Continuous Access EVA
• Provides remote d ata replication functionality on the EVA.
Virtualiz ation
Virtualization is used to simplify the creation, presentation, and administration of storage to multivendor
host servers in a Storage Area Net work (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 confi guration.
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
