Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of your 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.
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:
Lenovo XClarity Controller portal pageImportant
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 Lenovo XClarity Controller portal page.
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.NoteThe server does not support Disk Operating System (DOS).
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.
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.NoteFor 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
Light path diagnostics provides LEDs to help you diagnose problems and an LCD information display panel that provides additional diagnostic information. For more information about the light path diagnostics, see Front operator panel with LCD display and Light path diagnostics.
Mobile access to Lenovo Service Information website
The server provides a QR code on each system board that you can scan using a QR code reader and scanner with a mobile device to get quick access to the Lenovo Service Information website. The Lenovo Service Information website provides additional information for parts installation, replacement videos, and error codes for server support. See QR code for information about accessing the QR code label.
Active Energy Manager
Lenovo XClarity Energy Manager is a power and temperature management solution for data centers. You can monitor and manage the power consumption and temperature of Converged, NeXtScale, System x, and ThinkServer servers, and improve energy efficiency using Lenovo XClarity Energy Manager.
Redundant networking connection
The Lenovo XClarity Controller provides failover capability to a redundant Ethernet connection with the applicable application installed. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the optional redundant Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.
Redundant cooling and optional power capabilitiesThe server supports a maximum of four 1100-watt (110V or 220V ac), 1600-watt (220V ac), or 2000-watt (220V ac) hot-swap power supplies and six or twelve hot-swap fans, depending on the server configuration. The redundant cooling by the fans in the server enables continued operation if a fan fails.NoteYou cannot mix power supply types in the server.Two types of fans are supported:
60 mm x 38mm, 16K internal hot-swap fans (01CX965)
60 mm x 38mm, 19K internal hot-swap fans (01PG490)
Different fan types cannot be mixed within a system. All fans must be either 16K fans or 19K fans.
Before upgrading fans from 16K to 19K, you must make sure that the system has version 2 of the ThinkSystem 2-CPU, 24-DIMM, Compute System Board (01CV978) installed in each compute tray.
ThinkSystem RAID support
The ThinkSystem RAID adapter provides hardware redundant array of independent disks (RAID) support to create configurations. The standard RAID adapter provides RAID levels 0 and 1. An optional RAID adapter is available for purchase.
