Features
Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of the 
server. These design features make it possible for you to customize the system hardware to meet your needs 
today and provide flexible expansion capabilities for the future.
Your server implements the following features and technologies: 
•  Features on Demand
If a Features on Demand feature is integrated in the server or in an optional device that is installed in the 
server, you can purchase an activation key to activate the feature. For information about Features on

•  Lenovo XClarity Controller (XCC)
The Lenovo XClarity Controller is the common management controller for Lenovo ThinkSystem server 
hardware. The Lenovo XClarity Controller consolidates multiple management functions in a single chip on 
the server 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, 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 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
