Ethernet software" on page 139.
• Features on Demand software RAID support
The server provides Features on Demand software RAID support for RAID levels 5, 6, 50, and 60 upgrade.
Features on Demand software RAID upgrade is integrated into the integrated management module II
(IMM2). For more information, see "Enabling Features on Demand RAID software" on page 139.
• FlexNode Support
The Lenovo System x3850 X6 and x3950 X6 server provides support for reconfiguring a multinode server
into two independent, stand-alone servers, also known as FlexNode. When FlexNode support is enabled,
each scalable partition can support its own independent operating-system installation. Each scalable
partition has its own local resources as an independent server, and cannot access the resources or boot
the operating system of another stand-alone server while FlexNode is enabled. The FlexNode is a feature
of the Integrated Management Module II (IMM2).
For additional information, see "Configuring a multinode system" on page 131.
• Integrated management module II (IMM2)
The integrated management module II (IMM2) combines service processor functions, video controller, and
remote presence and blue-screen capture features in a single chip. The IMM provides advanced service-
processor control, monitoring, and alerting function. If an environmental condition exceeds a threshold or
if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in
the IMM event log, and alerts you to the problem. The IMM also provides a virtual presence capability for
remote server management capabilities. The IMM provides remote server management through the
following industry-standard interfaces:
– Intelligent Platform Management Interface (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3.0
– Common Information Model (CIM)
– Web browser
For additional information, see "Using the integrated management module" on page 133 and the

• Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and public secure keys.
It provides the hardware support for the Trusted Computing Group (TCG) specification. You can
download the software to support the TCG specification, when the software is available. You can enable
TPM support through the Setup utility under the System Security menu choice (see "Using the Setup
utility" on page 123).
• Large data-storage capacity and hot-swap capability
The server can support a maximum of eight 2.5-inch drives or sixteen 1.8-inch drives, or a combination of
both 2.5-inch and 1.8-inch drives when you use the supported SAS/SATA backplane configurations. With
the NVMe PCIe backplane installed, the server supports 2.5-inch hot-swap NVMe PCIe solid state drives.
For more information about the drives that the server supports, see "Installing drives" on page 66.
