Re: Storage Foundation License Tiering

Sounds like VERY old licenses.... When last did you renew maintenance?
Only letters have been used in recent years (A, B, C..), no longer combination of nubers and letters.
SUN V240 will for example be Tier A.
With renewed maintenance you should be able to see your current entitlement on the Licensing Portal:

Symantec has also added a new preferred way of licensing - Symantec Performance Value Unit (SPVU) 
See https://sort.symantec.com/land/inventory_licenses 

You can find SPVU calculator as well as Server Tier calculator over here:  https://sort.symantec.com/spvu_calc
