DELL PowerEdge R640 1U rack server 2x Xeon Silver 4116 2.1GHz 12-core 128GB DDR4 8x 1.2TB SAS H730P

Dual-socket 1U compute node

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores. It ships with 128 GB of DDR4 registered ECC memory across 8 modules and includes a PERC H730P controller with 2 GB cache driving eight 1.2 TB 10K SAS drives. Dual 750 W platinum power supplies and iDRAC9 Enterprise complete the dense scale-out platform.

Suits virtualisation farms, not GPU workloads

This configuration fits organisations running hypervisor clusters, database instances or high-performance computing tasks that benefit from 24 total cores and large memory capacity. The 2.5-inch drive bays and 12 Gb/s SAS backend support mixed RAID levels from 0 through 60. Buyers who require PCIe add-in cards such as GPUs or FPGA accelerators will find no full-height slots in this 1U chassis, and the installed drives are mechanical SAS units rather than solid-state media.

24 DDR4 slots define upgrade ceiling

The server provides 24 DIMM slots with a maximum supported capacity of 3 TB, so the current 128 GB population leaves substantial headroom for future expansion using registered ECC DDR4 modules. All memory channels are populated symmetrically across both CPUs, preserving optimal bandwidth as modules are added.
