Features

Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of your system. 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.

Chassis features

  • Redundant optional power capabilities

    The chassis supports up to three hot-swap CRPS power supplies, which provide redundancy.
    Important
    • CRPS power supply units in the chassis must have the same vendor, wattage, and part number (or alternate part number).
    • CRPS Premium (CFFv5) power supply units in the chassis must have the same wattage, and part number (or alternate part number).
  • Chassis management

    The chassis midplane with PSoC (Programmable System on Chip) allows monitor and management of nodes and power supply units in the chassis. A chassis caretaker node is selected by the PSoC firmware for chassis management.

    For the management interface, see Lenovo XClarity Controller portal page. In XCC, certain management functions can only be performed by the caretaker node, whereas other functions can be performed by all nodes.

Node features

Your node implements the following features and technologies:
  • Features on Demand

    If a Features on Demand feature is integrated in the system or in an optional device that is installed in the system, 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.

    The system supports Lenovo XClarity Controller 3 (XCC3). For additional information about Lenovo XClarity Controller 3 (XCC3), refer 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.

    Note
    The system 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 system supports TruDDR5 DIMMs operating at up to 6400 MHz. For more information about the specific types and maximum amount of memory, see Node technical specifications.

  • Large data-storage capacity

    With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.

    Storage capacity is different depending on server model. See Node technical specifications for more information.

  • Mobile access to Lenovo Service Information website

    The node provides a QR code on the system service label, which is on the node top cover, 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 system 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, and ThinkServer solutions, and improve energy efficiency using Lenovo XClarity Energy Manager.

  • ThinkSystem RAID support

    The ThinkSystem RAID provides software RAID (0, 1, 5, and 10) and hardware RAID (0, 1, 10, 5, 50, 6, and 60 standard).

1 By default, the caretaker node is automatically selected by the PSoC firmware on the chassis midplane. To change the chassis caretaker preference, see Configuring the D3 Chassis.
2 Only the caretaker node can perform PSU firmware update.
