RAID 5 8k Random Read/Write






The array goes through some internal activity for both connection methods during the 256 OIO measurement period. This skews the average performance of both connections during that measurement period significantly. Subsequent tests resulted in the same interference at this point in the test, so we use 128 OIO as our measurement for this test. The 12Gb/s JBOD averages 499,107 IOPS at 128 OIO, and the direct connection provides 499,109 IOPS. A variance just 2 IOPS is amazing.






The 12Gb/s JOBD tops out at 29,492 IOPS at 64 OIO, while the direct connection reaches 29,488 at 64 OIO.






Outside of the 0 percent write workload, which had significant GC activities for both connection methods, the results are identical.
