Project Name: dumps
Type of quota increase requested: Cinder detachable block storage
My guess is that the dumps project is probably one of the motivating reasons for the adoption of Cinder for Cloud VPS, especially since we need to use lots of instance storage. I'm looking at getting the quota increased to about 5 TB (and hopefully have it increased in the future, say 10 TB), so that each dumps instance can work with about 1-2 TB of temporary storage for archiving.
As for the number of volumes, an ideal number would be 8.
T159930 is a related task that got us the large storage instance flavor.
