Identifying Node Memory Locations
The DXi6900 G2 Node uses 16 GB memory modules (DIMMs). The Node has 24 memory sockets divided
into 2 sets (A and B) of 12 slots each. Each set (A or B) is dedicated to one CPU. Only 8 or 16 of the 24
memory sockets are populated with memory modules, depending on the configuration (see
).
Note:
Memory socket numbers are displayed on the clear window on the cooling shroud.
Note:
If one or more memory modules are failed or missing when the system starts up, the DXi enters
Limited Mode. In addition, a service ticket is generated.
