Hi= ,=3D

I&=3D #8217;m just setting up some storage for use with oVirt and am wondering wh= =3D y I might choose glusterfs rather than just exporting a raid array as iscsi= =3D . The oVirt team seem to be pushing gluster (though that could just b= =3D e because it’s a Red Hat product). Can anyone answer this one?<= =3D o:p>

What I have come up with is as follows.

For:

- <= =3D /span>easy to expand

- redundancy across storage devices/easy replication

- &nb= sp=3D ; high availablility

- = =3D performance

- = =3D it’s kind of cool J

- &nb= sp=3D ; maintenance?<= =3D o:p>

Against (these are guesses):

= - performance? (multiple layers of filesystems everywhere – fs in = =3D vm + image on gluster + gluster + block filesystem)

<=3D ![if !supportLists]>- &nbs= =3D p; complexity

- maintenance?

Any help here is appreciated. Also, does= t=3D he underlying block level filesystem matter here? VMs running under o= =3D virt would be typical business applications – file serving (samba4), = =3D email, databases, web servers, etc.

Cheers,

Justin.
