M-Cell Functional Overview
An M-Cell consists of M-racks and cooling racks and in most configurations a special cooling
distribution rack (CDU). When liquid-cooled blades are used in the system, the separate CDU
supplies water that dissipates heat off the system CPUs.
There is one 24-inch wide x 93-inch high cooling rack for every two M-racks in an M-Cell. The
cooling rack circulates conditioned air through the M-racks to cool the components within the
M-rack assembly. Figure 4-6 on page 64 shows the cooling rack at the center of the array with the
SGI logo on the front. Note that the cooling rack does
not
accommodate any compute or storage
components and is used strictly for cooling the M-Cell assembly.
The compute racks used in an M-Cell configuration are 33-inches (83.8 cm) wide; other size and
weight differences (compared to the D-Rack) are noted in Table 4-2. In the M-rack there are six
power shelves per blade enclosure pair.
