4.2 Multinode capabilities
The x3950 M2 is the initial base building block, or
their most basic, these nodes are comprised of four-way SMP-capable systems
with processors, memory, and I/O devices. The x3950 M2 is the building block
that allows supported 8-way, 12-way, and 16-way configurations by adding other
x3950 M2s as required.
Note: When we refer to an x3950 M2, we mean both an x3950 M2 or an
x3850 M2 that has the ScaleXpander Option Kit installed.
The x3950 M2 can form a multinode configuration by adding one or more
x3950 M2 servers. Various configurations are possible as shown in Figure 4-1.

Each node can be either an x3950 M2 or an x3850 M2
with the ScaleXpander Option Kit installed. All CPUs in
every node must be identical.

The possible configurations are:
A two-node complex comprised of two x3950 M2 servers, with four or eight
processors, and up to 512 GB RAM installed
A three-node complex comprised of three x3950 M2 servers, with six or 12
processors, and up to 768 GB RAM installed
A four-node complex comprised of four x3950 M2 servers, with eight or 16
processors, and up to 1 TB RAM installed
