I am getting the following error:
performance has deteriorated. I/O latency
increased from average value of 3605
microseconds to 109102 microseconds.

The problem comes and goes and I am suspecting the drives are an issue. They are 500gb sata raid 5.
We have about 10 VM's running all the time and they are always online. I wanted to get some advice on an approach to rectify the problem. The server is 6 years old and I was thinking of requesting a new one to migrate the VM's over time to utilize the old server elsewhere. I have noticed the ESX could be upgraded but if it goes south during an upgrade we have a lot which needs to be moved and we are now in a crisis situation.
What is truly the problem if it was working correctly in the past? What could be causing the IO latency?
