In my TSM environment we have around 100 nodes of different flavor (SAP,AIX,Windows,DB2,SQL etc..). Other then using different diskstorage pool for a particular policy domain, I am planning to use big diskpool (1TB) for all the policy domian, and enable collocation by node, so the data should not segregate to different tapes, and it will not become a nightmare while full restoration happens.
Advantages
1, There will be no issue of diskpool become full (small diskpool for different flavor) and backup is going to tape which will make the process slow.
2, Easy to administrator as there will be single diskpool.
Disadvantages
1, whenever migration will start, lot of tape drives are required as collocation is enabled (we have 18 drives)
Before implementing this, I want to confirm whether this will be useful or not, And what are the advantages/disadvantages it have.
