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, refer to the XCC documentation compatible with your server at:
https://sysmgt.lenovofiles.com/help/topic/lxcc_frontend/lxcc_overview.html
Important: Lenovo XClarity Controller (XCC) supported version varies by product. All versions of Lenovo
XClarity Controller are referred to as Lenovo XClarity Controller and XCC in this document, unless
specified otherwise. To see the XCC version supported by your server, go to

• UEFI-compliant server firmware
Lenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) compliant. UEFI replaces
BIOS and defines a standard interface between the operating system, platform firmware, and external
devices.
Lenovo ThinkSystem servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server 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 server supports synchronous dynamic random-access memory (SDRAM) registered dual inline
memory modules (DIMMs) with error correcting code (ECC). The server also supports Intel Optane DC
persistent memory modules (DCPMMs).
For more information about the specific types and maximum amount of memory, see "Specifications" on
page 3.
• Integrated network support
The server comes with one of several types of LOM adapter, which supports connection to one of the
following network types: 10GBASE-T (2-port or 4-port), 1GBASE-T (2-port or 4-port), or 2x 10Gb SFP+ (2-
port or 4-port). An ML2 form factor network adapter is also supported.
• 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.
Note: For customers in Chinese Mainland, TPM is not supported. However, customers in Chinese
Mainland can install a Trusted Cryptographic Module (TCM) adapter or a Lenovo-qualified TPM adapter
(sometimes called a daughter card).
• Large data-storage capacity and hot-swap capability
The server models support a maximum of 24 2.5-inch hard disk drives that are of the hot-swap Serial
Attached SCSI (SAS) or hot add/remove NVMe types (depending on system configuration).
With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.
• Light path diagnostics
