
The server supports four Intel® Xeon® scalable processors of the fourth generation, three
groups of 16GT/s UPIs, and 64 DDR5 DIMMs.

The server uses PCIe bus to connect to PCIe riser cards to provide PCIe slots of different
specifications.

The server supports up to 10 x16 PCIe 5.0 slots and up to 22 x8 PCIe 5.0 slots.

The server uses the AST2600 management chip to support management ports such as VGA
connectors and management network ports.
