    vSAN 6.7 High latency

    David_Beckham Lurker

      I am using three Lenovo X3650 M5 with N2210 (1:3 SSD:HDD) to test vSAN 6.7.

      The SSD is M500DC 480GB.

      Two 10G nexus cisco switches.

      I used HCIBench to test the performance.

       

      I found that the 95%tile_LAT is very high and I don't think it's acceptable.

       

      VMs = 1

      IOPS = 35555.20 IO/s

      THROUGHPUT = 138.89 MB/s

      LATENCY = 0.6710 ms

      R_LATENCY = 0.5180 ms

      W_LATENCY = 1.0280 ms

      95%tile_LAT = 170.0402 ms
