Scenario
A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN
solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have
the same local disk configurations:
Disk1 =50 GB
Disk2 = 100 GB
Disk3 = 256 GB
In addition, the environment includes a NAS filer. The average time to fully backup all virtual
machines on one ESX server using EMC DD Boost is three hours.
The customer is interested in implementing an EMC NetWorker solution with Data Domain as a
backup device. The backup server, storage nodes, and proxies are SAN-attached.
Refer to Scenario .
When using EMC NetWorker and DD Boost, what is the maximum number of concurrent backups
per VADP proxy server?

A.
40

B.
50

C.
