What hardware are you using SSD in? IBM DS8??? EMC VMAX or DMX HDS
If you have a VMAX 40K then the product FAST VP probably will replace the need for you to tune the SSD in HSM. If you have a DS8870 then Protect Tier or Fast Tier may replace the need to manage the SSD. The Hardware Storage Arrays are now taking over moving data that is "hot" to faster devices without HSM or the user knowing it is occurring.
