At the SAS Global Forum 2011 in the Grid architecture session , it was mentioned that SAS servers should be looking for a minimum I/O throughput of between 30-50mb/s per server (or Grid node).
There is a good SAS paper on how to test the I/O throughput of a SAS server on both Windows and Linux/Unix including code examples you can use.
You can find the paper here: http://support.sas.com/rnd/scalability/grid/grid_testingbench.pdf
If you run the code you might get the following error:
“ERROR: Shell escape is not valid in this SAS session.”
If so you will need to turn x commands on for the server, a SAS note outlining how to do that is here:
grid requires 30-50mb I/O through put per node
