I have a series of ~10 virtual machines, all of which share a common history. The machines are have Debian Linux filesystems, the base of which is about 30G with 1.8m individual files.
I'm seeking some experience or thoughs on these options. I have read http://blog.scottlowe.org/2008/08/05/flexclones-versus-deduplication-with-vmware-infrastructure/
The same question is at https://forums.netapp.com/message/18419#18419 (I'm a bit fuzzy on why there are two separate netapp supported forums)

I'd probably go with putting them all inside a single volume and potentially look at single-file FlexClone to make that easier.

Thanks for the 7.3 note on the size.
But single file FlexClone won't work. VMWare uses a large virtual file per VM. With Xen I have thousands of files per VM.
We'll be going with A-SIS, and lamenting that since all the VM's will be part of the same volume, a "disk full" condition in any one of them will bring them all down.
