Analysis by number of GbE ports:
For the six (6) GbE port systems the backup throughput was never
network limited. For the PowerVault DL2000 Value Series hardware
with only two (2) GbE ports, backup throughput rates were network
limited in all cases where there were two (2) or more enclosures. For
the one (1) enclosure case, there were not enough clients to saturate
the NIC bandwidth
Analysis by Backup Type:
Software compression and software encryption are performed
by the backup clients and thus do not impact performance of the
PowerVault DL2000 – Powered by Symantec media server. Software
compression can however increase end-to-end effective backup
throughput by reducing the size of the backup data before it is
transferred from the backup clients, as demonstrated in the results
above.
Note however that software compression and software encryption
consume processor resources on the backup clients and can
negatively impact end-to-end backup throughput if the clients do not
have sufcient processing power.
Conclusion
The Dell PowerVault ™ DL2000 – Powered by Symantec Backup Exec
provides a high performance, integrated backup-to-disk solution that
ts into any data infrastructure environment.
