DELL PowerEdge R640 1U Rack Server 2x Xeon Silver 4116 2.1GHz 12-Core 256GB DDR4 8x 600GB SAS H730P

Dense Dual-Socket 1U Server

The Dell PowerEdge R640 is a 1U rack server built for scale-out data centre workloads. It ships with two Intel Xeon Silver 4116 processors running at 2.1 GHz, each providing 12 cores. The system includes 256 GB of DDR4 registered ECC memory across 24 slots and a PERC H730P controller managing eight 600 GB 10K SAS drives. Dual 750 W platinum power supplies and iDRAC9 Enterprise complete the platform.

Virtualisation Hosts, Not GPU Farms

This configuration suits organisations running virtualised databases, hyper-converged clusters or dense web tiers that benefit from 24 cores and high memory capacity in a single rack unit. The quad-port 1 GbE and 10 GbE SFP+ daughter card supports converged networking. Buyers who require GPU acceleration or multiple PCIe add-in cards should consider larger chassis with full-height expansion slots.

24 Memory Slots Define Capacity Ceiling

The motherboard provides 24 DDR4 DIMM slots with a maximum supported capacity of 3 TB. Installed memory uses eight 32 GB modules at 2400 MHz, leaving 16 slots available for future upgrades. This slot count is the primary factor when planning memory growth for memory-intensive applications such as in-memory databases or large VM densities.
