Reclaim wasted space on equallogic SAN

We have two equallogic boxes in production and one out in DR that hold our virtual servers and file storage. We also have a few MD1000s that are empty. There is a lot of wasted space on the SANs and we are running out of room for files. Dell's solution is to buy new SAN and play musical volumes to reclaim the wasted space but we are reluctant to spend money on a SAN when all we really need is some reconfiguration of our existing volumes.
Has anyone else dealt with this and found a solution or does anyone know any storage consultants who could help us wisely use our existing storage and not try to sell us any new hardware?

I have been an EqualLogic customer for about five years. Can you define what you mean by wasted space? Are you using thin provisioning on all of your volumes? What are your RAID levels? Have you looked at trimming down the snapshot reserve for
your volumes?

If you have a volume that has been written to such that the blocks are in use when thin provisioned but the filesystem shows that they are free, there is currently no way to re-thin that volume. There is a way with the release of the version 6 of the EqualLogic firmware. Otherwise, a fat volume May need to be copied to a new volume to make it thin again. You can also adjust RAID levels and replication reserve. Long story short, there are many ways to delay making another EqualLogic purchase. If you just need some temporary capacity, your local VAR might be able to get you a unit.

All of my volumes are thick and we have already gone the RAID adjustment route. I am thinking of moving support server VMs to local storage but no one seemes to do that and I am not sure why.

If you are already running RAID50, why not just convert youth volumes to thin? It is just a single check k box for each role, and is reversible, and doesn't have a performance impact.

Moving those VMs to local storage won't free up any SAN space because those blocks have already been allocated and written. You would need to move the VMs to local storage, and then migrate the remaining data to a new volume and then delete the original volume...unless you are running the 6.x firmware.

Darn autocorrect. Going from thick to thin is just a checkbox for each VOLUME in the EqualLogic GUI.
