• Hot-swappable drives.

RAID controller card:

• Supports a variety of RAID controller cards. Use the Computing Product Compatibility Checker to obtain information about the specific PCIe plug-in RAID controller cards supported.

• Supports RAID level migration, drive roaming, self-diagnosis, and web-based configuration. For details about the RAID controller card, see the Atlas 800 AI Training Server RAID Controller Card User Guide (Model 9000).

FlexIO card A

The mainboard supports one FlexIO card A. The FlexIO card provides the following network ports:

• Two 100GE optical ports, supporting 100GE optical fibers or copper cables.
• Four 25GE or 10GE optical ports, supporting PXE.
  CAUTION:

  • When a 100GE optical port supports a 100GE copper cable, the CPUs do not support auto-negotiation. In this case, the auto-negotiation function must be disabled on the peer device.
  • The two 100GE optical ports of each FlexIO card are from different CPUs. You are not advised to bind network ports. Network port binding will deteriorate performance.

  • Different optical modules can be used to support 25GE or 10GE optical port rate.

FlexIO card B

An NPU supports a maximum of four FlexIO cards B. Each FlexIO card B provides the following network ports:

Two 100GE optical ports, supporting 100GE optical fibers or copper cables.
