there are a few performance/write

Two things jump out at me from these results. First is that using GlusterFS
replication for ephemeral storage seems . . . strange. Is there some reason
that the OpenStack setup can't use local storage

euca is backed by local disks in a raid/lvm layout

When running a ftbfs run on both euca and openstack I started to see some
pretty big differences in performance. CPU and mem were all the same or
close enough so I decided to look at disk performance.
euca is backed by local disks in a raid/lvm layout and/or exported via
iscsi through the Stor
