This Dual Controller has the capability of having as much as 32GB of Cache, and 16 x 8Gbps Fibre ports, or iSCSI ports.

There are no drives in this controller, but it can support all of the HUS100 Series drives in this category, using the correct expansion frames, which include, but not limited to, the DBS, DBL, and DBX.

The most popular model of the HUS150 is the CBL,  which is what is quoted here.
