Combining D2D And Vls In An End-To-End Solution For Robo/Regional Dcs And Main Data Center Using Hp Data Protector - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

Recovery options: Depending on retention time on the VLS, data can be recovered directly from VLS
on the remote site or if that retention has expired then a copy should be archived on physical tape
which is again directly available from the remote site over the extended SAN.
Solution advantages:
• Data off-sited as part of the initial backup, good resilience solution, no delays
• Part of an Active/Active Data Center disaster recovery solution
• Backup load can be split across sites 50:50 – best use of all available resources
• No data offsiting costs for physical tape – it is already offsite with this method
Solution trade-offs: Company must be willing to invest in multiprotocol routers and DWDN inter site
link technology at some cost.
Combining D2D and VLS in an End-to-end Solution for ROBO/Regional DCs and Main Data
Center using HP Data Protector
Company requirements: Protect data anywhere mentality – bring all data home to the main data
center. Use the right technology at the right price for the right location.
Solution: HP D2D in remote offices and regional data centers. VLS in regional data centers and main
data center. All with deduplication and replication enabled.
Caveats: Sizing replication target size and links is critical; use the HP StorageWorks Backup Sizer.
This solution needs a very structured implementation.
ISVs: HP Data Protector has the best integration in this end to end scenario with scripted automated
importing of the replicated data cartridges at the regional data centers and main data centers.
Device configuration highlights: Probably single VTL configured on D2D at remote sites , four slot
mappings per D2D virtual library is possible at regional data center. VLS at regional data center
should have one library dedicated to accepting data from D2D at regional data center. Regional
data center and main data center use of VLS units as local backup resources should be deployed to
provide as many parallel backup paths as possible.
Backup application configuration highlights: D2D units are polled (scripted) by HP Data protector for
recently replicated cartridges, VLS units email Data Protector for recently replicated cartridges. Both
of these trigger an automated catalog import at the replication target sites (HP unique feature).
