The CR-brick is a 4U-high enclosure that contains the compute and memory
functionality for the SGI Altix 3700 Bx2 system. Figure 5-1 on page 66 shows a front and
side view of the CR-brick.
The CR-brick is divided into separate nodes that are connected internally by high-speed
NUMAlink channels. Each node has two 64-bit processors and 12 memory DIMM slots
connected to a custom-designed application-specific integrated circuit (ASIC). This ASIC
is the heart of the CR-brick, and it provides an intelligent interface between the
processors, memory, network fabric, and peripheral I/O.
