Hi, Hope you can help.
We have three Dell R710 esx hosts, all patched and up to date with the same architecture/cpu. We purchased two identical ones early last year and the third in Jan this year with as similar spec as possible. On the surface it appears that this newer server is the same.
We have configured them in the same way and they are in a cluster with vmotion and DRS running happily. All VM's are hosted on a netapp filer via NFS. Everything is running smoothly, except for one thing:
This new server reports higher disk latency than the first two, I have attached a screenshot. I can't find any reason for the difference. Can anyone shed some light on this?
The 5ms base line seems to be independant of load, number or activity of guest OSs.
