Hi,

Just throwing in my 2 pence.

Depending on the nature of the deployment, the "occasional snapshot" 
can become the daily snapshot or even more frequent, depends how many 
customers you have and what need they have of the snapshots (i.e. for 
regular backups).
In these cases the NFS backed secondary storage can quickly become a 
bottleneck.
I'd either push for making the secondary storage VM glusterfs-aware (or 
at least NFS v3 via TCP) or enable Swift for the zone (and use the 
glusterfs-swift proxy - UFO).
I'm not sure what Swift's role is in Cloudstack, but if it's what I 
think it is then it should scale much better.
