PR611 Description
A vision or analytics server often needs more cards than a standard ATX board has slots for: a GPU, two frame grabbers, a fast network card and an NVMe carrier. The DFI PR611 series is a 305 x 244 mm ATX server motherboard with six PCIe slots for that kind of build, one socketed Intel Xeon Scalable processor, six memory slots and an operating range of -5 to 65 °C.
Its LGA 3647 socket takes 1st and 2nd Gen Intel Xeon Scalable processors on the Intel C621 chipset. DFI lists 31 models across Platinum, Gold, Silver and Bronze, from eight cores up to 24 cores on the Platinum 8160T and Gold 6252N, at up to 150 W TDP. Six 288-pin DDR4 slots take up to 384 GB of registered ECC memory at up to 2933 MHz, and DFI lists Intel Optane DC persistent memory support in two slots with selected 2nd Gen processors.
Two builds make up the series. PR611-C621DRI carries the ASPEED AST2500 BMC, with IPMI remote management on a dedicated LAN port and a VGA output, for systems that must be managed without a site visit. PR611-C621DR is the headless build with two GbE ports and no display output, for servers reached only over the data network.
Both builds have two GbE ports on Intel I210AT controllers. The rear panel carries four USB 3.1 Gen 1 and two USB 2.0 Type-A ports, with two USB 3.1 Gen 1 and three USB 2.0 on internal headers, and one RS-232 port on a DB9 connector with ±15 kV air-gap ESD protection. Expansion is three PCIe x16 and three open-ended PCIe x8 slots, all Gen3, with the x8 slots sharing lanes with the x16 slots. An M.2 2280 M-key takes NVMe at PCIe Gen3 x4 or SATA, an M.2 2230 E-key takes a wireless module on PCIe Gen3 x2 or USB 2.0, and six SATA 3.0 ports support RAID 0, 1, 5 and 10.
Power comes from an ATX supply on 24-pin and 8-pin connectors. The -5 to 65 °C range gives more margin in a warm cabinet than a standard 0 to 60 °C board. TPM 2.0 is optional, and each board has a programmable watchdog 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 PR611 series configured with the processor, registered ECC memory, storage, add-in cards, cooling and an OS image, then tested before it ships. PR610 is DFI's C621 ATX board with a PCI slot and two COM ports, ICX610 moves to 3rd Gen Xeon Scalable (Ice Lake-SP) with PCIe Gen4 and up to 512 GB, and PR811 takes two Xeon Scalable processors on an EATX board with six PCIe slots and dual 10GbE. Our team can advise on processor choice against the cooling in the chassis, memory sizing, the slot plan for GPUs and capture cards, and whether IPMI suits the way the system is supported.
