Technical Specifications

Form factor

2U rack server

Chipset

Intel^® C622

Processors

Supports one or two processors.

• Intel^® Xeon^® Scalable (Skylake and Cascade Lake) processors
• Built-in memory controller and six memory channels
• Built-in PCIe controller, supporting PCIe 3.0 and 48 lanes per processor
• Two UPI buses between processors, providing up to 10.4 GT/s transmission per channel
• Up to 28 cores (2.7 GHz)
• Max. 3.8 GHz (four cores)
• Min. 1.375 MB L3 cache per core
• Max. 205 W TDP

Memory

Supports 24 memory modules of the following types:

• Up to 24 DDR4 memory modules
• Max. 2933 MT/s memory speed
• RDIMM and LRDIMM support
• The DDR4 memory modules of different types (RDIMM and LRDIMM) and specifications (capacity, bit width, rank, and height) cannot be used together.

Storage

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

• Supports two M.2 SSDs.
  • M.2 SSDs are supported only when the server is configured with an Avago SAS3004iMR RAID controller card.
  • The drive letter of the M.2 SSDs managed by the Avago SAS3004iMR RAID controller card can be set to sda by modifying the GRUB parameters only when the RAID controller card is used with an SR130, SR760IT-M, SP150IT-M, or SmartRAID 3152-8i RAID controller card or a PCH.
  NOTE:

  • The M.2 SSD module is used only as the boot device when the OS is installed. 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.

    Use enterprise-level high endurance (HE) SSDs or HDDs for data storage.

  • The M.2 SSD is not recommended for write-intensive service software due to poor endurance.
  • Do not use the M.2 SSD as the cache.

• Supports hot swap of SAS/SATA/NVMe drives.
  NOTE:

  The NVMe drives support:

  • 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.

• Supports a variety of RAID controller cards. Use the Computing Product Compatibility Checker to obtain information about the specific RAID controller cards supported.
  • The RAID controller card supports RAID configuration, RAID level migration, and drive roaming.
  • The RAID controller card does not occupy a standard PCIe slot.

    For details about the RAID controller card, see the Atlas 800 Inference Server RAID Controller Card User Guide (Model 3010).

• Supports SAS HBA cards or SAS RAID controller card (with a 1 GB, 2 GB, or 4 GB cache) to improve storage performance and data security.
  NOTE:

  If the BIOS is in legacy mode, the 4K drive cannot be used as the boot drive.

Network

Supports expansion capability of multiple types of networks.

• LOM
  • Supports two 10GE optical ports and two GE electrical ports via the NIC chip integrated on the mainboard.
  • Supports two 10GE electrical ports and two GE electrical ports via the NIC chip integrated on the mainboard.
  • The LOM ports support NC-SI, WOL, and PXE.
• FlexIO card
  • Supports on-demand configuration.
  • Supports a variety of FlexIO cards. Use the Computing Product Compatibility Checker to obtain information about the specific FlexIO cards supported.

I/O expansion

10 PCIe 3.0 slots:

• One slot dedicated for a RAID controller card, one dedicated for a FlexIO card, and eight for standard PCIe cards.

  For details, see PCIe Slots and PCIe Slot Description.

• Support Huawei proprietary PCIe SSD cards to bolster I/O performance for applications such as searching, caching, and download services.
• Support AI accelerator cards.

Ports

Supports a variety of ports.

• Ports on the front panel:
  • Two USB 2.0 ports
  • One USB 3.0 port
  • One DB15 VGA port
  NOTE:

  For the server that uses 12 x 3.5", 20 x 2.5" (8 x SAS/SATA + 12 x NVMe) or 25 x 2.5" drive configuration, the front panel provides only two USB 2.0 ports.

• Ports on the rear panel:
  • Two USB 3.0 ports
  • One DB15 VGA port
  • One RJ45 serial port
  • One RJ45 system management port
  • Two GE electrical ports
  • Two 10GE electrical ports or 10GE optical ports
• Built-in ports:
  • One USB 3.0 port
  • Two SATA ports
  NOTE:

  In the 8 x 2.5" or 24 x 2.5" drive configuration, only two SATA built-in ports are provided.
