Dell PowerVault DL2100 - Manual (Page 7)

Effective throughput measurements for the DL2000 Standard Edition
with Value Series hardware performing both Weekly Full and First
Full backups were consistently ~1.5 TB/hr, with two (2) MD1000
enclosures providing marginally better effective throughput than one
(1).
With deduplication disabled, the DL2000 Advanced Deduplication
Edition with Performance Optimized hardware outperforms the
DL2000 Standard Edition with Value Series hardware due to its
superior processor and memory capabilities.
Conclusion
The Dell PowerVault ™ DL2000 – Powered by CommVault ® Simpana ®
8 provides a high performance integrated backup-to-disk solution
that fits into any data infrastructure environment. By incorporating
deduplication as a feaure in the software into the backup

is eliminated and long term operational savings can be achieved.
