A customer wants to integrate a P4500 Multi-Site SAN Solution in their environment. Currently,
their infrastructure consists of two EVA systems. The customer has 18TB of Tier-1 and 6TB of
Tier-2 data, which need different performance and availability levels.
You design a P4000 Virtual SAN Appliance (VSA) solution on VMware vSphere4 with one DL380
G7 in each datacenter to utilize existing EVA disk space for the Tier-2 data.
You recommend an HP D2D Backup System and HP Data Protector for a backup solution. You
design a dedicated iSCSI network for the D2D and P4000 solution.
Which step must be performed in the customer’s backup application to achieve an optimal
deduplication ratio and optimal performance?

A.
enable multiplexing

B.
configure block size

C.
implement device load balancing

D.
raise disk agent buffers
