The following figure shows the layout of the CPUs and DIMMs inside the chassis. The
front of the system is at the top of the figure.
Figure 7 CPU and memory locations
Dual in-line memory modules (DIMM) come in various sizes, which must be configured
in a certain way. This topic can help you select the correct configuration when
servicing DIMMs.
The storage processor contains two Intel processors each with an integrated memory
controller that supports four channels of memory. The storage processor allows two
DIMM slots per channel, so the storage processor supports a total of 16 DIMM slots.
