Cell Board
The cell board contains the processors, main memory, and the CC ASIC that interfaces the processors and
memory to the off-board I/O. The CC provides a crossbar connection, which allows communication with other
cell boards in the system. It connects to the PDH and SINC hardware. Each cell board holds up to 16 DIMMS.
There can be one or two cell boards installed in a server. The cell boards have hot-plug capability.
