3.18 Partitioning
The 8-socket x3950 X6 server has ability to form a 2-node configuration using a feature called
partitioning. The x3950 X6 server electronically splits to two independent servers or nodes
which use their own set of resources and have own operating system installed.
When partitioning is enabled, the eight-socket server is seen by installed operating systems
as two independent four-socket servers, as shown in Figure 3-32.

3.19 Standard onboard features
In this section, we describe standard onboard features in the X6 servers such as Integrated
Management Module II, UEFI, Integrated Trusted Platform Module (TPM), and light path
diagnostics.
This section covers the following topics:
3.19.1, “Integrated Management Module II (IMM2)” on page 96
3.19.2, “UEFI” on page 97
3.19.3, “Integrated Trusted Platform Module (TPM)” on page 97
3.19.4, “Light path diagnostics” on page 98
3.19.1 Integrated Management Module II (IMM2)
Each X6 server has an IMM2 onboard, which is the next generation of the IMM used in eX5
servers. The IMM2 provides the following major features as standard:
IPMI v2.0 compliance
Remote configuration of IMM2 and UEFI settings without the need to power on the server
Remote access to system fan, voltage, and temperature values
Remote IMM and UEFI update
UEFI update when the server is powered off
Upper 4-socket node
Lower 4-socket node
