A large enterprise currently has an HP Virtual Library System (VLS) and plans to migrate to an HP
StoreOnce 6200 Backup System. Which best practice must the enterprise consider during this
migration?

A.
The HP VLS should be connected to a Fibre Channel switch.

B.
No more than 16 data streams should be run to a single VLS device concurrently.

C.
They should use NPIV to connect the HP StoreOnce 6200 Backup to the nodes as different devices.

D.
Multiplexing is not recommended for the HP StoreOnce 6200 Backup

Explanation:

Do not send multiplexed data to StoreOnce B6200/D2D Backup Systems. “Multiplexing” data
streams from different sources into a single stream in order to get higher throughput used to be a
common best practice when using physical tape drives. This was a necessity in order to make the
physical tape drive run in streaming mode, especially if the individual hosts could not supply data

fast enough. But multiplexing is not required and is in fact a BAD practice when it comes to D2D or
B6200 deduplication devices.
Note:
* Users familiar with the HP VLS System should be aware that the HP StoreOnce B6200 Backup
System does not behave in the same way and needs a completely different approach when
architecting and tuning for best performance. Do not assume that an HP B6200 Backup System can
replace an HP VLS System without major re-evaluation of requirements and alignment with HP B200
best practices.
