Benchmarks – Sequential and Mixed Workloads

Our Sequential read/write workload is centered on 128K transfer sizes with QD ranging from 1 to 128.


RAID 0 showed solid read performance starting at 250 MB/s at QD1 and peaking at 1200 MB/s QD16. Write performance started at 225 MB/s and peaked just shy of 800 MB/s.


RAID 5 had a slight performance decrease with our starting point at 275 MB/s read and 250 MB/s write. This moves up to 710 MB/s read and 550 MB/s write at QD16 and finishes nearly the same.


On to RAID 6, We see throughput start at 210 read and 225 write. QD16 comes in at 730 MB/s read and 475 MB/s write, while we finish at 700 read and write.

Mixed Workloads


Database started strong near 4000 IOPS in RAID 0 followed by RAID 5 near 3500 IOPS and RAID 6 closer to 3200 IOPS. At QD16, these numbers are 16,000, 7500, and 5100, respectively, and they finish at 14,000 for RAID 0, 8,000 for RAID 5 and 7,000 for RAID 6.


File Server showed a peak of 20,000 IOPS in RAID 0 QD128 with RAID 5 peaking at 13,000 IOPS QD32 and RAID 6 10,000 IOPS QD128.


Email Server was very strong for RAID 0. Here we have a touch over 18,000 IOPS QD64. RAID 5 reached 9000 IOPS at QD64 and RAID 6 peaked at QD32 with a hair under 7000 IOPS.


Back at it, Web Server showed the DS1517+ very well suited for this type of workload. All three RAID types scaled very well within this test with peaks just above 19,000 IOPS for RAID 0, 17,000 for RAID 5 and 16,000 for RAID 6.


Workstation was by far the highest performing workload we tested. Here I have a peak of 23,000 IOPS in RAID 0 QD64 and QD128. RAID 5 topped out at 13,000 IOPS with RAID 6 bringing it all together at 13,200 IOPS QD64.
