Installing the Memory Modules
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. The Node ships from the factory with 16 GB memory modules (DIMMs) pre-installed
in 8 memory sockets, for a total of 128 GB of memory.
For 119 TB and larger configurations, install the 8 provided 16 GB memory modules in the Node (see
). Memory modules must be installed in the correct sockets in order for the system to function
).
Note:
Memory socket numbers are displayed on the clear window on the cooling shroud.
