Hello Grégoire,
I suggest you to look EMC scaleio for block based operations. It has a free one
too ! And as a block working better then Ceph ;)

Hi Ivan,
Thank you for your quick reply.
I'll have a look on Ceph and related perfs.
As you mentionned, 2 DRDB nfs servers can do the job, but if I can avoid
using 2 blades for just passing blocks to nfs, this is even better (and
maintain them as well).
Thanks for pointing to ceph.

Hi, Grégoire,
You could have
- local storage if you like, so every compute node could have own space
(one lun per host)
- to have Ceph deployed on the same compute nodes (distribute raw devices
among nodes)
- to dedicate certain node as NFS server (or two servers with DRBD)
I don't think that shared FS is a good option, even clustered LVM is a big
pain.
