Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of your solution. 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 solution implements the following features and technologies:
  • 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 Features on Demand website

  • 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 page


    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 solutions are capable of booting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.

    The server does not support Disk Operating System (DOS).
  • 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 up to maximum of 2,048 GB system memory. 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.

  • Integrated network support

    The tray comes with an integrated 1-port Gigabit Ethernet controller with RJ-45 connector and 1-port 25Gb Ethernet controller with SFP28 connector, which support 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.

    For more information on TPM configurations, see “Enable TPM/TCM” in the Maintenance Manual.

    For customers in Chinese Mainland, 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 two 2.5-inch 7mm simple-swap Serial ATA (SATA)/Non-Volatile Memory express (NVMe) solid-state drives per node.

    • Supports up to one 2.5-inch 15mm simple-swap Serial ATA (SATA)/Non-Volatile Memory express (NVMe) solid-state drive per node.

  • Light path diagnostics

    Light path diagnostics provides LEDs to help you diagnose problems. For more information about the light path diagnostics, see Light path diagnostics panel and Light path diagnostics LEDs.

  • Mobile access to Lenovo Service Information website

    The solution provides a QR code on the system service label, which is on the cover of the solution, 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 solution support.

  • 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, ThinkServer solutions and ThinkServer servers, and improve energy efficiency using Lenovo XClarity Energy Manager.

  • Optional power capabilities

    The solution supports a maximum of six 1800-watt or 2400-watt hot-swap power supplies.
    • SD650 V2 tray supports 1800-watt or 2400-watt hot-swap power supplies.

    • SD650-N V2 tray supports only 2400-watt hot-swap power supplies.

    Do not mix 1800-watt and 2400-watt power supplies in the same unit of solution.
  • ThinkSystem RAID support

    The ThinkSystem RAID provides software RAID supports for RAID level 0 and 1, while integrated on-board hardware RAID supports for RAID level 1.
