Benchmarks – Sequential and Mixed Workloads

Our Sequential read/write workload is centered on 128K transfer sizes with a Queue Depth of 128

Sequential read performance topped out at 118.5 MB/s in RAID 0. RAID 5 and 6 reached 118.4 MB/s and 118.6 MB/s, respectively.

Write performance was at its highest with RAID 0, reaching 118.5 MB/s while RAID 6 touched 90 MB/s and RAID 5 111 MB/s.

Mixed Workloads Throughput and Latency

Moving on, I found the 6404T to perform the highest in workstation near 16000 IOPS. Database wasn't far behind with file and email server holding nearly identical performance.

RAID 5 showed near 10000 IOPS for workstation in RAID 5, with database coming second near 8000 IOPs.

RAID 6 gives us 13000 IOPS for workstation, this is followed by 8000 IOPS for database.

Latency results show near 18ms in Web Server at the highest with the lowest being 9ms for workstation and database.

Moving to RAID 5, we see near 90ms latency at QD128 for Email Server. 19ms for both Web and Database as the lowest.

Finishing up, we have RAID 6 and database showing 8ms of latency at QD128. At the highest point, we have 27ms of latency for file server.
