Im on the latest gluster, was following recommendations about
tune-up, improved results, but still have less then 50Mb/sec. Yes,
current version of DRBD stops on 2 nodes, but next one 9.x will
support up to 32 (need to be verified).
True, but I have not heard it being that slow before, also if
you do go with gluster use 3.3. if you are looking for ease of
setup gluster is easy. And drdb stops at 2 nodes doesnt it.

From my experience gluster write performance (2 mirrored
nodes) is very low, approx 40-45Mb/sec. read is pretty high
and it was network saturation - appr 90-95Mb/sec (i have
gigi network). For HA for VMs i'd highly recommend
DRDB+Pacemaker+Corosync. Solution is much more advanced, and
requires much more efforts, but output will cover all time
expenses. I have cluster of 2 nodes with DRBD, some VM
images (block devices, using Logical Volumes on top of DRDB)
are up to 512G. I don't see any performance loss. Also
Pacemaker is well integrated with XEN live migration. So i
think it's best solution for "cheap man".
