Dense 1U dual-socket server

The PowerEdge R640 is a 1U rack server built for dense scale-out deployments. It carries two Intel Xeon Gold 6148 processors, each with 20 cores at 2.4 GHz and a 3.7 GHz turbo frequency. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight modules. A PERC H730P controller with 2 GB cache manages storage.

For virtualisation and compute clusters.

This server suits environments that need high core counts and fast networking in a single rack unit. The quad-port 1GbE and 10Gb SFP+ daughter card supports heavy east-west traffic. Buyers who need GPU acceleration or more than two processors should look elsewhere because the chassis maxes out at two sockets and has no GPU clearance.

24 DDR4 slots with 3 TB maximum capacity

The motherboard provides 24 DIMM slots and supports up to 3 TB of DDR4 registered ECC memory. This ceiling determines whether the platform can grow with your dataset or if a larger chassis is required.
