A couple of years ago I added notes on speeding up physical to virtual conversion using VMware’s Stand Alone Converter 5. Recently, I had to do another conversion, this time with Converter version 5.5.3.
I’m happy to report that the original fix still works: remove the encryption layer from the converter. I got speeds of up to 45MB/sec over fiber. I mentioned in the first post that choosing to thin out the VMDK disks would also help the speed. Now, I don’t think that’s necessary. I used the thick provisioning option, added size to the VMDKs and split the physical server’s original RAID volume into two separate virtual disks during the process and the performance was just as good.
