FCCPR811-C622IR Overview
An inference server with several GPUs needs slots, lanes and memory more than it needs a monitor. The PR811-C622IR is the base build in the DFI PR811 series of dual-socket EATX server motherboards, with no BMC module fitted, two Xeon Scalable sockets and five PCIe x16 slots for the cards.
Both LGA 3647 sockets take 1st and 2nd Gen Intel Xeon Scalable processors on the Intel C622 chipset, each from eight to 24 cores at up to 150 W TDP. Two 20-core Gold 6230 processors give 40 cores to feed the GPUs, and a pair of 24-core Gold 6252N or Platinum 8160T gives 48. We fit the processors and coolers to the chassis airflow. Twelve DDR4 slots take registered ECC memory at up to 2933 MHz, up to 768 GB.
Expansion is five PCIe x16 slots and one open-ended PCIe x8 slot, all Gen3. Two 10GbE ports on an Intel X557-AT2 bring in data from cameras or storage, with two GbE ports on Intel I210AT controllers for management. The rear panel has four USB 3.2 Gen 1 and two USB 2.0 Type-A ports and an RS-232 DB9, with two USB 3.2 Gen 1, three USB 2.0 and a second RS-232 inside. An M.2 2280 M-key takes NVMe or SATA and eight SATA 3.0 ports support RAID 0, 1, 5 and 10.
The PR811-C622IR runs from an ATX supply on 24-pin and 8-pin connectors and operates from 0 to 40 °C, with CE, FCC, UKCA and RoHS compliance and TPM 2.0. For a local screen, PR811-C622IRV adds VGA through a BMC module, and PR811-C622IRI adds IPMI remote management with VGA.
