Benchmarks - iSCSI Workload Latency

In our database workload, we found latency touching 17ms with RAID 0, within each array type a few ms of latency was added due to the overhead associated. SSD caching increased latency in this particular workload, much like it reduced throughput earlier.

File Server showed a latency result of 22ms in RAID 0, while RAID 5 and 10 offered 24ms and 31ms, respectively. We also noticed the benefit of SSD caching within this workload, lowering the overall latency of RAID 5 from 24ms to 16ms.

Email Server touched 15ms in RAID 0, with RAID 5 and 10 at 22ms and 30ms, respectively. Caching again improved latency by quite a margin, down to 8ms in this case.

Web Server took a page from Email Server, where we saw SSD caching lowering the latency from 27ms to 8ms in RAID 5. RAID 0 topped at 27ms, while RAID 10 offered 38 ms.

The Workstation workload offered 21ms to RAID 0, followed by 22ms for RAID 5 and 26ms to RAID 10. Latency improved dramatically using SSD caching, dropping to just 5ms.
