[Gluster-users] Gluster with ZFS

[gagan tiwari]

HI Alexander,
                              Thanks for the update. Initially, I  also
thought of deploying Ceph but ceph is quite difficult to set-up and manage.
Moreover, it's also  hardware demanding. I think it's most suitable for a
very large set-up  with hundreds of clients.

What do you think of MooseFS ?  Have you or anyone else tried MooseFS. If
yes, how was its performance?

Thanks,
Gagan
