We too are considering a mass expansion of our storage pools to implement
Disk to Disk backup via TSM. The reason is to enhance recovery times. The
Nexsan ATABeast is under consideration.  We currently have about 40TB backed
up to TSM storage pools. I am thinking of bringing in MANY TB of ATABeast so
that we can discontinue migration to tape. I am curious as to what happens
internally in TSM when you drive your storage pool utilization to, say, 80%
and hold it there?  Are there any performance penalties?  Any cautions? Any
real world experience?  How much ATA should I consider?
