I'm not sure what the perf aspects would be but it depends on what the VMware software passes through. Does it ignore cache sync commands in its i/o stack? Got me. You won't be missing out on reliability but you will be introducing more layers in the stack where something could go wrong. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
