Large Scale Backup Consolidation (No Deduplication); Using Vls For Large Scale Consolidation - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

• Cost effective
• Easy disaster recovery solution if physical tape copy is regularly off-sited
Solution trade-offs: Take care to size the solution correctly. VLS9000 entry level scales to 40 TB before
you need to purchase additional connectivity kits.
Other information: HP strongly recommends using the backup application to perform the copy from
the VLS to physical tape. This provides a single management console for all activities and better
utilization of physical media through object copy technology.

Large Scale Backup Consolidation (No Deduplication)

Company requirements: Up to 500 TB backup storage required in a single unit, high throughput
required to meet backup windows.
Solution: Multi-node VLS9000 using Object copy to physical tape.
Caveats: Very large systems (greater than 300 TB) might be better split into two smaller systems for
increased availability. With a single large VLS, typically one storage pool is configured which means
if any full shelf in the VLS is lost (highly unlikely) then all virtual media is lost. But configuring multiple
storage pools to overcome this means increased manageability overhead.
ISVs: Data Protector, Netbackup, Networker, TSM, Commvault. See a full list at
go/ebs.
Device configuration highlights: Create as many virtual devices as you need and dedicate devices to
certain SAN hosts by using the LUN mapping functionality.
Backup application configuration highlights: For best throughput, schedule as many backups in parallel
as you can. Use object copy functionality to schedule copy to physical tape.

Recovery options: Typically direct from VLS, single file restores will be particularly fast; set retention
periods accordingly. Older copies of data can be recovered directly from physical tape if required.
