It's the 9550SX.  Don't confuse it with the 9500S.

The 9550SX adds a PowerPC 400 series embedded microprocessor for off-
loading RAID-5/buffering to the traditional 64-bit ASIC design.

The 9500S has only the 64-bit ASIC, and does buffering to DRAM directly
(not nearly as capable).

The 9550SX really raises the bar on feature support of the 3Ware
products, putting some things in hardware that people are paying storage
vendors for doing in software (typically in a dedicated, external
storage device).

should definitely build the new release (as well as upgrade the
3DM2 release) to support the added capabilities of the added PowerPC.
