[Gluster-devel] Does gluster suit my need?

[Alsan Wong]

Hi,

Thank you for your clarification.

Yes, I don't need the GlusterFS actually. All I need from the GlusterFS is
the AFR, and this seems to have to pay a high price. Using NFS + some batch
backup script may work more efficiently.

The interesting part is GlusterHPC. The computing cluster host should have
sufficient power to run multiple VMs. So, can the GlusterHPC helps to share
the processing power across the VMs is the point. I can't find too much
information on GlusterHPC, or what scenario is the best for GlusterHPC.
