The Origin 350 server system can be configured with or without a NUMAlink module. If
the system does not have a NUMAlink module, this configuration is referred to as a base
configuration. If the system has a NUMAlink module, it is referred to as a NUMAlink
configuration.
The NUMAlink module, which is the key component of the NUMAlink 3 interconnect,
transfers messages among up to eight compute modules. If the system does not have a
NUMAlink module, the NUMAlink 3 interconnect consists of a cable that connects a
compute module to another compute module, an MPX module, or a PCI expansion
module.
Table 2-1 lists the minimum and maximum ranges of the configurable items for the base
and NUMAlink configurations.
