Form factor

2U rack server

Chipset

Intel^® C621A

Processor

Supports one or two processors.

• Third-generation Intel^® Xeon^® Scalable Ice Lake processors
• Built-in memory controller and eight memory channels per processor
• Built-in PCIe controller, supporting PCIe 4.0 and 64 lanes per processor
• Three UPI buses between processors, providing up to 11.2 GT/s transmission per channel
• Up to 40 cores
• Max. 3.6 GHz
• Min. 1.5 MB L3 cache per core
• Max. 270 W TDP

DIMM

• Up to 16 DDR4 memory modules
  • RDIMM and LRDIMM support
  • Max. 3200 MT/s memory speed
  • The DDR4 memory modules of different types (RDIMM and LRDIMM) and specifications (capacity, bit width, rank, and height) cannot be used together.
  • A server must use DDR4 memory modules of the same P/N code.

Storage

Supports a variety of drive configurations. For details, see Drive Configurations.

• Supports two M.2 SSDs.
  • M.2 SSDs are supported for RAID configuration when the server is configured with an Avago SAS3004iMR RAID controller card.

  NOTE:

  • The M.2 SSD is used only as a boot device for installing the OS. Small-capacity (32 GB or 64 GB) M.2 SSDs do not support logging due to poor endurance. If a small-capacity M.2 SSD is used as the boot device, a dedicated log drive or log server is required for logging. For example, you can dump VMware logs in either of the following ways:
    • Redirect /scratch. For details, see https://kb.vmware.com/s/article/1033696.
    • Configure syslog. For details, see https://kb.vmware.com/s/article/2003322.
  • The M.2 SSD cannot be used to store data due to poor endurance. In write-intensive applications, the M.2 SSD will wear out in a short time.

    If you want to use SSDs or HDDs as data storage devices, use enterprise-level SSDs or HDDs with high DWPD.

  • The M.2 SSD is not recommended for write-intensive service software due to poor endurance.
  • Do not use M.2 SSDs for cache.
• Supports hot swap of SAS/SATA/NVMe U.2 drives.

  NOTE:

  When NVMe drives are configured:

  1. NVMe drive pass-through model:
     1. Supports CPU pass-through without RAID configuration and Intel VROC VMD NVMe RAID configuration.
     2. VMD function usage note:
        • Before using the VMD function, contact technical support engineers of the OS vendor to check whether the OS supports the VMD function. If yes, check whether the VMD driver needs to be manually installed and check the installation method.
        • Surprise hot swap if the VMD function is enabled and the latest Intel VMD driver is installed.
        • Orderly hot swap if the VMD function is disabled.
  2. NVMe drive switch model: supports only the CPU pass-through without RAID configuration.

  3. NVMe drive Tri-Mode model: Only PCIe RAID controller cards are supported, and each NVMe slot only supports PCIe 4.0 x2 bandwidth. For details about how to support RAID controller cards, see the V6 Server RAID Controller Card User Guide.
• Supports a variety of RAID controller cards. For details, see “Search Parts” in the Compatibility Checker.
  • The RAID controller card supports RAID configuration, RAID level migration, and drive roaming.
  • The RAID controller card supports a supercapacitor for power-off protection to ensure user data security.
  • The PCIe RAID controller card occupies one PCIe slot.

  For details about the RAID controller card, see V6 Server RAID Controller Card User Guide.

Network

Supports expansion capability of multiple types of networks.

• OCP 3.0 network adapter
  • The FlexIO card slot supports OCP 3.0 network adapters, which can be configured as required.
  • Supports orderly hot swap.

    NOTE:

    The OCP 3.0 network adapter supports orderly hot swap only when the VMD function is disabled.

  • Supports a variety of OCP 3.0 network adapters. For details, see “Search Parts” in the Compatibility Checker.

I/O expansion

Supports 9 PCIe slots.

• One PCIe slot dedicated for a screw-in RAID controller card, one FlexIO slot dedicated for an OCP 3.0 network adapter, and seven PCIe slots for standard PCIe cards.

  For details, see PCIe Slots and PCIe Slot Description.

• Support GPU cards.

Port

Supports a variety of ports.

• Ports on the rear panel:
  • Two USB 3.0 ports
  • One DB15 VGA port
  • One RJ45 serial port
  • One RJ45 management network port

• Built-in ports:
  • One USB 3.0 port
  • Two SATA ports

Video card

An SM750 video chip with 32 MB display memory is integrated on the mainboard. The maximum display resolution is 1920 x 1200 at 60 Hz with 16 M colors.
