• Features on Demand
If a Features on Demand feature is integrated in the solution or in an optional device that is installed in the
solution, you can purchase an activation key to activate the feature. For information about Features on
Demand, see:

• Lenovo XClarity Controller (XCC)
The Lenovo XClarity Controller is the common management controller for Lenovo ThinkSystem solution
hardware. The Lenovo XClarity Controller consolidates multiple management functions in a single chip on
the node system board.
Some of the features that are unique to the Lenovo XClarity Controller are enhanced performance, higher-
resolution remote video, and expanded security options. For additional information about the Lenovo
XClarity Controller, see:

• UEFI-compliant server firmware
Lenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) 2.5 compliant. UEFI
replaces BIOS and defines a standard interface between the operating system, platform firmware, and
external devices.
Lenovo ThinkSystem solutions are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The solution does not support DOS (Disk Operating System).
• Active Memory
The Active Memory feature improves the reliability of memory through memory mirroring. Memory
mirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If a
failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair
of DIMMs.
• Large system-memory capacity
The solution supports synchronous dynamic random-access memory (SDRAM) registered dual inline
memory modules (DIMMs) with error correcting code (ECC). For more information about the specific types
and maximum amount of memory, see "Specifications" on page 3.
• Integrated network support
The tray comes with an integrated 1-port Gigabit Ethernet controller with RJ-45 connector, which
supports connection to a 1000 Mbps network.
• 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.
Trusted Platform Module (TPM) has two versions - TPM 1.2 and TPM 2.0. You can change the TPM
version from 1.2 to 2.0 and back again.
For more information on TPM configurations, see "Enable TPM/TCM" in the Maintenance Manual.
Note: For customers in the People's Republic of China, a Lenovo-qualified TPM 2.0 adapter or a Trusted
Cryptographic Module (TCM) adapter (sometimes called a daughter card) may be pre-installed.
• Large data-storage capacity
The simple-swap solution models support the following drives:
– Supports up to four 2.5-inch simple-swap Serial ATA (SATA) hard disk drives per tray
– Supports up to two 2.5-inch simple-swap Serial ATA (SATA) NVMe solid-state drives per tray
