Best practice would be to have a mirrored disk pool, but as we all know disk isn't as cheap as tape. To be more cost effective you could migrate to your regular backup storage pool and then move off to tape later. -- Joshua S.

I would think not however I would think the advantage of having a separate one would be that when a file is requested, TSM would be more likely to find it on disk and not have to mount a tape to retrieve it. So perhaps for performance reasons it�d be �nice�.. Since I�ve not seen an environment with HSM in use I�m curious as to what the �best practice� is.. to create one or no and why?
