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.

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.

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
