George,
        I'm not really sure what the difference is, I'm guessing that the SSA 
controller needs to support Fast-Write Cache, and I believe it's a chip on the 
controller with memory(cache) for doing this.  For example if I run the 
following command:

# lscfg -vl ssa0
  DEVICE            LOCATION          DESCRIPTION
        
  ssa0              10-68             IBM SSA 160 SerialRAID Adapter
                                      (14109100)

        Part Number................. 27H1204
        FRU Number.................. 34L5388
        Serial Number...............S0157201
        EC Level....................    E28728
        Manufacturer................IBM053
        ROS Level and ID............8300    0000
        Loadable Microcode Level....05
        Device Driver Level.........00
        Displayable Message.........SSA-ADAPTER 
        Device Specific.(Z0)........SDRAM=128 
        Device Specific.(Z1)........CACHE=32
        Device Specific.(Z2)........UID=000008005AEBED5A
        Device Specific.(YL)........P2-I3/Q1

You see it's a model 160 adapter, and in the Z0 and Z1 fields it has the 
amount of SDRAM and CACHE on board the controller.  Check yours out and see 
what it has.
