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
