Industry-Leading PerformanceArchitectural improvements

– More powerful emulation engine– More aggregate bandwidth per system

Write Cache Consolidation– Consolidates small blocks– Bypasses cache and sends directly to disk

DL4200 and DL4400 dual-engine systems

– Twice the processing power– Ideal for compression environments

Backup Application function also runs on integrated media server

–Faster time to recovery–Improves backup server performance–Flexible cloning functions

Single point of control to manage virtual and physical tape pools

* Requires NetWorker7.3 and NetBackup 5.1

Other VTL products require separate points of control.

“The Blind Spot” – Virtual Tape Example

Backup Server

Physical Tape

Library

Tape Environment

Command / Action

Remove Tape Afrom library

Tape A is out of library

Database /Record

Tape A isout of library

Blind Spot – Virtual tape actions are “blind” to the backup application until the tape is removed from library. Actions are not controlled or tracked by the backup application.

Virtual Tape Library

CDL moves / ejects Tape A from library

Use Case: Restore

How Does it Work?Backup application shows the location of virtual or physical tapeBackup application issues a restore command to CLARiiON Disk Library or physical libraryRestore occurs from either the CLARiiON Disk Library or physical tape library

How Does it Works at Others?Backup application showed the tape was located (ejected) outside the physical libraryRequired tape (virtual or physical) was found inside the VTL application or through an offline processRestore occurred from either the CLARiiON Disk Library or physical tape library via Pass-Through mode

Benefits• 100% of the tape pool managed by

the backup application• Improve audit trail of all tape assets • Time saved looking for tapes,

resulting in faster restores11
