Testing datastore speed from VMware

We are looking at ways to debug slow datastores. Right now we are using a linux VM and standard linux disk speed tests on the local VM's disk, but does anyone know if a better way?

A reading of 25 or higher for DAVG in ESXTOP is a good indicator of a disk latency caused by the array.  Not much use if you already know the problem is with the array....

Re: Testing datastore speed from VMware

Are you looking for OS to disk speeds, or Guest to Guest speeds?

 

Also, are these just Linux guests or Windows also?
