Hi,
I've not done anything with GlusterHPC, but from a storage point of view, if your storage is already centralised, I'm not sure there's a lot to be gained by using GlusterFS ... ??
Technically, if you have local storage on each node then GlusterFS/Unify is a useful solution, but the performance overhead compared to local storeage can be notable.
Gareth.

Hi,
Sorry, I can't fully get your point. Do you mean:
1. I can gain processing power (to help running the VMs) from other nodes of the computing cluster by using GlusterHPC.
2. In this case, using NFS instead of GlusterFS would be better.
No, I didn't try NFS, because I need the AFR.

Sure.
If you're just after processing power, have you tried NFS?

Hi,
Not exactly. I'd like to run the VMs at the computing cluster host (cause it does have dual quad core CPU with VT support), and gain processing power from other nodes of the computing cluster by using GlusterHPC. The VMs image remains on the computing cluster host, and the data would goes to the GlusterFS.
Does it feasible?

Hi,
Are you talking about sitting the VM storage on the GlusterFS in the form of disk images?

Hi,
I get several machines, some of them are old (actually, not that old, just 2
to 3 years). I would like to build a big cluster like this:
I'll divide those machines into three groups, computing, storage, backup
storage. As their name, the computing group would be a cluster of physical
machines which is responsible to run application.
Best of all, the computing cluster would run several virtual machines across
the cluster. Thus, the server of the computing cluster would run vmware or
xen, and hosting serveral virtual machines inside (note: the no. of virtual
machines may more then physical machines). The other machines in the cluster
would be diskless (all storage goes to the storage and backup storage
cluster), and act as the processing power supplier and the being the
terminal to the virtual machines.
As I know, such similar architecture can be constructed by using EnSpeed
(another OSS project on clustering, http://www.enspeed.com ) easily, but one
of the requirement for me is hard to fulfill - they require all CPUs of the
cluster nodes support VT, and that is not possible in my situation.
I've notice that another project, Kerrighed ( http://kerrighed.org ) do also
fit the needs of my computing cluster, I might try it later.
So, can I build a such cluster by using GlusterHPC + GlusterFS? or do I need
to combine another solution(s)?
