Hi Sreec,
There are some queries in Oracle DB waiting for I/0, hence trying to figure out where exactly the problem resides.
2 ESXi servers hosting 1 each oracle VM and these VM's are in RAC. We see average physical disk latency above 20ms, average Queue and kernel latency less than 1ms.
Max phy disk latency at 150ms, kernel latency as 3ms and queue latency as 6ms.
To understand storage performance do we need to consider only average values for a time interval or teh max values?
What does these valuses signify, whr does the problem reside, storage,kernel or queue stack?
CPU and memory of these VM's are less than 25% utilized.
