Partitioning - IBM System x3850 X5 Implementation Manual

As shown in Figure 2-12 on page 33, the following scalability is possible:
Memory scaling: A MAX5 unit can attach to an eX5 server through QPI link cables. This
method provides the server with additional memory DIMM slots. We refer to this
combination as a
System scaling: Two servers can connect to form a single system image. The connections
are formed by using QPI link cables. The x3850 X5 and HX5 support this type of scaling.
For more information about system-specific scaling options, see the following sections:
IBM System x3850 X5: 3.6, "Scalability" on page 70
IBM System x3690 X5: 4.6, "Scalability" on page 128
BladeCenter HX5: 5.8, "Scalability" on page 188

2.6 Partitioning

You can operate the HX5 scaled system as two independent systems or as a single system,
without removing the blade and taking off the side-scale connector. This capability is called

partitioning

Advanced Management Module (AMM) in the IBM BladeCenter chassis for the HX5.
Figure 2-13 depicts an HX5 system that is scaled to two nodes and an HX5 system that is
partitioned into two independent servers.

x3690 X5 and x3850 X5: The x3690 X5 and x3850 X5 do not support partitioning.
Figure 2-14 on page 35 and Figure 2-15 on page 35 show the scalable complex configuration
options for stand-alone mode through the Advanced Management Module of the BladeCenter
chassis.
