vSAN 6.7 High latency

[David_Beckham]

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
