DFI PR811-C622IRI Intel Xeon Scalable LGA 3647 Dual-Socket EATX Server Board with C622 Chipset, IPMI Remote Management and Dual 10GbE

A GPU server at a remote site or in a shared data room has to be recoverable without a site visit. The PR811-C622IRI is the IPMI build in the DFI PR811 series of dual-socket EATX server motherboards, fitted with DFI’s SEM2500-VGA/IPMI module for remote power control and monitoring, plus a VGA output at up to 1920 x 1200.

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, up to 48 cores across the pair. We fit the processors and coolers to the chassis airflow. Twelve DDR4 slots take up to 768 GB of registered ECC memory at up to 2933 MHz, which suits large models and data sets held in memory.

Networking is two 10GbE ports on an Intel X557-AT2 and three GbE ports, two of them on Intel I210AT controllers, with IPMI on the BMC module. Five PCIe x16 slots and one open-ended PCIe x8 slot, all Gen3, take GPUs and capture cards. 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-C622IRI runs from an ATX supply on 24-pin and 8-pin connectors and operates from 0 to 40 °C, with TPM 2.0 and CE, FCC, UKCA and RoHS compliance. Where remote management is not needed, PR811-C622IRV keeps the VGA output, and PR811-C622IR is the headless base build.
