Identifying Node Memory Locations
The DXi6900 G1 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 Table 1 3
and Figure 57).
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.
