Increase Performance on Clustered Storage by disabling/removing VHD's of Unused Dev Servers

Hi Experts,

We are trying ascertain which option would be best in terms of increasing performance across our clustered storage which is divided into 3 volumes (volume 1, 2 and 3).

At present we have many unused development servers sitting on our clustered storage which are still active.  What we would like to know is, in order for us to see an increase in performance would simply disabling those dev servers increase performance or would we have to remove the dev server VHD's from clustered storage for there to truly be a marked increase in performance?

So simply disabling servers VS moving VHD's off of clustered storage.

Any assistance would be appreciated.

all you will be doing is freeing up space and not changing the performance at all. The number or size of files in a CSV have nothing to do with its performance unless you are running low on storage capacity where the physical drive has to do many seeks to find a free cluster to write to.

The number of i/o's per second remain the same whether or not drive is empty or 3/4's full and if these files are not being accessed they consume no iops.. Adding more drives to a raid array (several small drives compared to fewer large drives) dos improve read performance (penalty in write performance) as the reads are separated among the various drive spindles.
