I have this running in production. only not with 2 machines, but with 4 machines, doing raid-10 ( not mdraid10, but conventional 2 sets of raid-1's 0'd )
I thought the original object was to make the space available to multiple VMware ESX(i) servers so you could vmotion guests among them. Can ESX construct raids out of multiple iscsi sources?
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.
