Re: [Xen-users] any recent experience combining GlusterFS w/ Xen?

Oh I did the reply thing again.... I am wondering how GlusterFS has performed providing VDI storage?

Sure, which part are you interested in? DRBD appears to be used for
one of the internal subsystems (a database). Nimbula uses Gluster,
along with Hadoop for the rest of their Cloud.

So far, I like what I see, mostly. It's clearly done by a bunch of
experienced systems guys. E.g. they have a sane CLI, unlike XCP. In
short, they've put together a bunch of sophisticated technology,
using people who really understand what they are doing.

The biggest question in my mind is scalability. Right now, the
networking setup is questionable. Your weakest link appears to be
the backplane of the router. That is, they use one single ethernet
segment for everything. That has clearly got to change. But still,
for a young product, I'm liking what I'm seeing.

Note that I haven't installed their recent upgrade yet, so things may
have changed with their 2.x product.
