Please help: My VM is trapped in the Starwind data image!

I just installed starwind free edition on a windows server 2008R2 with 10k SAS disks and created a single 500GB target, with data- deduplication.

I then added the iSCSI target to VmWare ESX 5 and formatted it as VMFS v3, and moved a single 80 GB VM onto it.

Now the Starwind data target is performing so slowly that I can't boot the VM or get the VM out of it!

--> Is it possible to mount the starwind data volume locally in order to pull the VM out of it?

--> Could data-deduping have anything to do with this crippling performance? Ive used starwinds before and Ive never seen it do this in the past with non deduped disks.

1.Yes, it is possible to connect to target locally
2.Why dont you try storage motion to move VM to another datastore?
3.I think that you met performance issue not because the deduplication, but because how it was configured, or maybe because of the hardware on the SAN server, or its settings. Would you please doublecheck if all the stripe/block sizes are the same (including the deduplication block size)?
