Second tier storage: Putting our DFSMS/HSM ML1 data on FATA-disk
We would like to put our DFSMS/HSM ML1 data on FATA-disk. After some calculations we found out that a 150 TB second tier buffer would be big enough to store one year of ML1 data. Older data will be sent to a virtual tape system (SUN/STK VSM).
What are people’s opinions as to whether this is a good thing to do?
