Hi,
I'm just setting up some storage for use with oVirt and am wondering why I =
might choose glusterfs rather than just exporting a raid array as iscsi. T=
he oVirt team seem to be pushing gluster (though that could just be because=
it's a Red Hat product). Can anyone answer this one?
What I have come up with is as follows.
For:
- easy to expand
- redundancy across storage devices/easy replication
- high availablility
- performance
- it's kind of cool :)
- maintenance?
Against (these are guesses):
- performance? (multiple layers of filesystems everywhere - fs in =
vm + image on gluster + gluster + block filesystem)
- complexity
- maintenance?
Any help here is appreciated. Also, does the underlying block level filesy=
stem matter here? VMs running under ovirt would be typical business applic=
ations - file serving (samba4), email, databases, web servers, etc.
Cheers,
Justin.
