For the DL2000 - Powered by CommVault ® Advanced Deduplication Edition, the following general guidelines were used to configure deduplication for the primary storage policy copies: • Specified the magnetic library mount paths for the deduplication database (referred to as the deduplication store in the Simpana Interface).
Results and Analysis Figure 1 and Figure 2 below compare the effective throughput measurements for First Full and Weekly Full backups on the DL2000 - Powered by CommVault ® Advanced Deduplication Edition utilizing one (1) and two (2) MD1000 enclosures. Figure 3 below compares the effective throughput measurements for First Full and Weekly Full backups on the DL2000 - Powered by CommVault ® Standard Edition utilizing one (1) and two (2) MD1000 enclosures.
3 As seen in the charts above, effective throughput measurements for the DL2000 Advanced Deduplication Edition with Performance Optimized hardware performing Weekly Full backups with deduplication enabled were consistently 1.5 TB/hr or above. Effective throughput for First Full backups for the DL2000 Advanced Deduplication Edition were ~600 GB/hr and ~1 TB/hr for one (1) and two (2) MD1000 enclosures, respectively. With deduplication enabled, First Full backups (e.g.
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.
