[Gluster-users] GlusterFS & XenServer Baremetal

[Alexandre Emeriau]

So this is not doable :) in regards to :
* more than the throughput of a single server, if not in overall speed, then
in width.
* being able to add more bricks in and have the expectation of increased
storage capacity and throughput.

No hope or ideas for getting a better situation ?
If not, what scenario did you switch for ?
