NVMe SSDPR611-C621DR Overview
A multi-camera inspection server usually lives in a rack beside the line, reached over the network by the engineers who look after it. The PR611-C621DR is the headless build in the DFI PR611 series of ATX server motherboards, with six PCIe Gen3 slots for GPUs and frame grabbers and no BMC or display output.
The LGA 3647 socket takes one 1st or 2nd Gen Intel Xeon Scalable processor on the Intel C621 chipset. DFI lists 31 models, from the eight-core Bronze 3106 and Silver 4209 to the 22-core Gold 6238T and 24-core Gold 6252N, at up to 150 W TDP, so the core count can follow the number of camera streams. Six DDR4 RDIMM slots take up to 384 GB of registered ECC memory at up to 2933 MHz.
Two GbE ports on Intel I210AT controllers carry the data and management networks. The rear panel has four USB 3.1 Gen 1 and two USB 2.0 Type-A ports and an RS-232 port on a DB9 with ±15 kV air-gap ESD protection, with two USB 3.1 Gen 1 and three USB 2.0 more on headers. Three PCIe x16 and three open-ended PCIe x8 slots, all Gen3, take the card set, with the x8 slots sharing lanes with the x16 slots. Storage is an M.2 2280 NVMe or SATA slot and six SATA 3.0 ports with RAID 0, 1, 5 and 10, and an M.2 2230 E-key takes a wireless module.
The PR611-C621DR runs from an ATX supply on 24-pin and 8-pin connectors and operates from -5 to 65 °C. DFI lists Windows 10 IoT Enterprise LTSB, Windows Server 2019 and 2016, and Linux. For remote power control and a local VGA output, PR611-C621DRI adds IPMI through the AST2500 BMC.
