Sun did something like this with the v60 and v65 servers, and they should do it again with the SSR212MC2.
The heart of the SAS subsystem of the SSR212MC2 is the SRCSAS144E . This card is interfacing with a Vitesse VSC410 SAS-expander and is plugged into a S5000PSL motherboard. This card is closely related to the MegaRAID SAS 8208ELP . All the drives, 12, in front are SAS/SATA-II hotswappable. http://www.intel.com/design/servers/storage/ssr212mc2/index.htm . This is a pure Intel reference design. This is the most drives that fits into a 2U **EVER**. This is the best storage product in existence today. The SRCSAS144E is a MegaRAID SAS controller. Sun's "own" v60 and Sun v65 were pure Intel reference servers that worked GREAT!
