I have no idea :) my setup has no vmware or any other form of
virtualisation in place there. the iscsi blockdev's are exported from 4
different machines ( each running with an areca-1220 with 8 disks ),
imported into a single machine - the storage-head, where mdraid does my
raid10 across those iscsi devices. this new volume is then exported over
a series of nfs points to various machines on the same subnet.
my point was just that this kind of a distributed setup is possible and
works well, as long as you can document and monitor the various points well.
