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.
