So how are people using (planning to use) large disk pools (either random or FILE - with or without Sanergy)?
Migration's one process per node seems to limit the usefulness of the large disk pool to implement disk to disk backup. A large disk pool appears useful for: 1) Large number of nodes with small to medium size backups (small, medium, large and huge are dependent on your hardware) and you migrate to tape. 2) Disk pool is large enough to contain all primary backup data and you do no migration to tape. A large disk pool does not appear useful for: 1) Small number of nodes with large to huge size backups. TDP nodes would be a good example of this (our case). Is there some work-around for this migration issue?

Migration has historically run as one process per node's data, so what you are seeing seems to say that this remains true today. Richard Sims, BU
