Hi All,
Small setup with one ESXi server/one production VM.VM is running on local data store of ESXi server(RAID 6 configured).Raid 6 configured in hardware level and created a datastore with multiple hard disks.Data store size 18.19 TB
Please note:- ESXi os is running on one local data store.VM is running on another data store which size is 18.19 TB
Only one production VM is running on ESXi server.VM has 3 VMDK and the size is around 12 TB.
We are facing performance issue and currently suspecting this performance issue is related to disk latency.Could you please help me to dig further on this case?
CPU & memory usage is under normal and seeing disk latency in periodic intervals.
ESXi version is 6.0.0 U2
Windows 2012 VM -->VMtools running(Out of date)
realtime stats:-
Disk stats:- Accepted latency should be less than 10 ms.here it is above 20 ms in regular intervals.
vdisk stats: Accepted latency should be less than 5 ms.Here it is above 15 ms in regular intervals.
Commands checked:- Device Max Queue Depth: 128.Both OS data store and VM data store queue depth is 128.
esxcli storage core device list --device naa.60030480197e
Device Max Queue Depth: 128
No of outstanding IOs with competing worlds: 32
