Cell Board
The cell board, illustrated in
Figure 1-7
, contains the processors, main memory, and the CC
application specific integrated circuit (ASIC) which interfaces the processors and memory with
the I/O, and to the other cell board in the server. The CC is the heart of the cell board, enabling
communication with the other cell board in the system. It connects to the processor dependent
hardware (PDH) and micro controller hardware. Each cell board holds up to two processor
