Right. I did a little reading, and a way to get a little bigger pool, but not lose IOPS seem to be to add several vdevs in the pool. So, what if the VM pool would consist of totally 4 disks , two (mirrored), in each vdev.
Then, if we assume I am using 240 GB drives, the pool would be 480 GB, be mirrored, and have some oomph, would that be correct? Would that be the way to go?
Seems overkill, but disk cost is irrelevant, since they´re just sitting here anyway.
