We are running a stretched cluster 6.7 u3 with 10 hosts but every now and then we get impacted by storage latency issues. All devices cache and storage are ok and are not reporting any issues
However we get with storage latency issues with the VMs and when looking at the vsan storage metrics at the host level we get very high delayed IO Average Latency
Assuming the network is ok does anyone know what could cause this measurement to go so high
I have also checked cache evictions and this checks out ok as well
Thanks in advance
