Managing Data Retention And Reducing Backup Storage Costs - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

Solution advantages:
• Massive scalability in terms of capacity and performance, "hot add" capability for adding capacity
and nodes
• High availability features in nodes and back-end disk arrays
• Flexible emulations in terms of number of libraries, drives, slots, and media sizes
• Easy disaster recovery solution if physical tape copy is regularly off-sited
Solution trade-offs: To guarantee scalable performance, each array module of 30 TB or 40 TB is a
single component and cannot be split. Sizing capacity and throughput correctly is important to the
solution being priced competitively.
Other information: HP strongly recommends using the backup application to perform the copy from
VLS to physical tape. Single management console for all activities and better utilization of physical
media through object copy technology.

Managing Data Retention and Reducing Backup Storage Costs

Company requirements: To improve RPO objectives, reduce expenditure on ever increasing backup
storage, better manage data growth for backup, provide more data online, reduced dependency on
tape.
Solution: VLS9000 with deduplication (licensable feature).
Caveats: Needs specific data type support with ISV software. Best practices include using small
cartridges (fewer than 300 GB). Some scripting changes will be required for stream naming conventions
with RMAN Oracle backups. Can take several days for space to be fully reclaimed.
ISVs: Data Protector, Netbackup, TSM – with Unix files, Windows files, SQL, Exchange, Oracle and
NDMP. See http://www.hp.com/go/ebs.
Device configuration highlights: Size using the HP StorageWorks Backup Sizer; the smaller the virtual
media the faster deduplication and space reclamation will happen.
Backup application configuration highlights: The only change required is that RMAN scripts need to
be changed to ensure consistent stream naming. Needs strict control over backup policy naming.
