PR811 Description
Multi-GPU inference, large vision systems and analytics servers tend to run out of slots and memory before they run out of rack space. The DFI PR811 series is a 305 x 330 mm EATX server motherboard with two Xeon Scalable sockets, 12 memory slots and six PCIe slots, five of them x16, for GPU and capture-card heavy builds.
Both LGA 3647 sockets take 1st and 2nd Gen Intel Xeon Scalable processors on the Intel C622 chipset. DFI lists 31 Platinum, Gold, Silver and Bronze models, each from eight to 24 cores at up to 150 W TDP, so the pair runs from 16 cores with two Silver 4110 parts to 48 cores with two Gold 6252N. Twelve 288-pin DDR4 slots take registered ECC memory at up to 2933 MHz, up to 768 GB.
Three builds differ by the BMC module. PR811-C622IR is the base build with no display output, for servers managed over the network. PR811-C622IRV fits DFI’s SEM2510-VGA module for a VGA output at up to 1920 x 1200. PR811-C622IRI fits the SEM2500-VGA/IPMI module for VGA and IPMI remote management, with a third GbE port.
Every build has two 10GbE ports on an Intel X557-AT2 and two GbE ports on Intel I210AT controllers. The rear panel carries four USB 3.2 Gen 1 and two USB 2.0 Type-A ports, with two USB 3.2 Gen 1 and three USB 2.0 on the board, and one RS-232 port on a DB9 with a second on an internal header. Expansion is five PCIe x16 slots and one open-ended PCIe x8 slot, all Gen3. Storage is an M.2 2280 M-key for NVMe at PCIe Gen3 x4 or SATA and eight SATA 3.0 ports with RAID 0, 1, 5 and 10.
Power comes from an ATX supply on 24-pin and 8-pin connectors. The boards operate from 0 to 40 °C, so the chassis needs airflow sized for two processors and the cards, and they carry CE, FCC, UKCA and RoHS compliance. TPM 2.0 is fitted, with a watchdog programmable from 1 to 255 seconds and Realtek ALC887 audio. DFI lists Windows 10 IoT Enterprise LTSB, Windows Server 2019 and 2016, and Linux.

Official DFI USA Distributor
Things Embedded is an official DFI USA distributor, supplying the PR811 series configured with both processors, registered ECC memory, storage, GPUs and add-in cards, cooling and an OS image, then tested before it ships. PR810 is DFI's other dual-socket C622 EATX board, with a PCI slot for a legacy card, PR611 takes one Xeon Scalable processor on a C621 ATX board with six PCIe slots, and ICX610 moves to 3rd Gen Xeon Scalable (Ice Lake-SP) with PCIe Gen4 on an ATX board. Our team can advise on the processor pair against the cooling in the chassis, memory population across two sockets, power and airflow for several GPUs, and RAID layout across the SATA and M.2 drives.
