I'm running 7.1.4 on RHEL 6.6. Using FILE device class deduped storage pool and will be converting to directory containers in the not too distant future.
I keep getting asked how much data will be added to TSM for new servers. This is not at all an easy answer in a deduplicated environment. I think there may be a way to get this information, but not from any tables accessible to TSM. So I figure there should be DB2 tables where I can figure out the following:
Node A uses extents a,b,c
Node B uses extents b,d,e
So Node A has distinct extents a and c, but then I'd need to know the size of the extents.
Maybe there's another way of getting the amount of data reduction for a node? Then I could average the amount of data reduction of a given platform. Maybe the only thing I can do is scan the activity log for ANU2526I, but that really wouldn't tell me how much a NEW client is going to add to the storage pool.
Anyone looked at this? Am I spitting into the wind?
