[Xen-users] Network Storage

["lists@xxxxxxxxxxxx" <lists@xxxxxxxxxxxx>]

Another area of problems is that of using network storage.

In my case, I'm using legacy 1GB and 2GB fibre channel storage units connected 
into fc filers that hand off NFS/CIFS. It's a nice, simple setup but in trying 
various combinations, things are still very slow and sluggish.

I've tried various things such as having an NFS or direct FC share onto each VM 
server, then installing the guest onto the network storage. Works fine but when 
you start adding servers, things get a bit difficult.
The servers run just fine, nice and fast but, the gotcha so far, seems to be 
when copying files across that storage for any of the servers. So for example, 
when copying say large backup files, GB sized, that slows down everything way 
too much.

So I'm wondering how others deal with network based storage when it comes to 
virtualization of this type.
