Lets back up a bit.
What are you using zfs for?
The use case will defiantly effect your choice of solution.

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

Since ZFS is a local FS, you are essentially limited to how much
storage
you can stick into one machine, yes.

I don't think that is giving you the kind of long term scalability
you might expect.

I'm running GlusterFS in a small cluster for backup storage.

For that use case I would actually recommend Ceph over GlusterFS,
since
that can be pretty easily scaled out to very large setups, e.g.
CERN is
using multiple Ceph clusters sized at several PB and their use cases
usually include very fast I/O.
Another concern is that Ceph is being quite actively developed whereas
GlusterFS development seems to have slowed down to ... not much,
these days.
Kind regards,
Alex.
