DELL PowerEdge R940 3U rack server 4× Xeon Gold 5120 2.2 GHz 14-core 768 GB DDR4 8× 600 GB SAS

Four-socket Xeon server for dense workloads

The Dell PowerEdge R940 packs four Intel Xeon Gold 5120 processors into a 3U rack chassis, giving 14 cores per CPU at 2.2 GHz with turbo to 3.2 GHz. Seventy-six-eight GB of DDR4 registered ECC memory is installed across 24 modules, leaving room to grow toward the 6 TB maximum. An H730P controller manages eight 600 GB 10K SAS drives, while an X520/I350 card adds dual 10 Gb SFP+ and dual 1 GbE ports. Dual 1600 W platinum power supplies and iDRAC9 Enterprise complete the package.

Suits compute-heavy tasks needing maximum cores

Database clusters, virtualisation hosts and in-memory analytics benefit from the four-socket layout and large memory capacity. The eight 2.5-inch drive bays limit raw storage volume, so workloads demanding many terabytes of local capacity should consider platforms with more bays or external arrays. The installed 10K SAS drives prioritise IOPS over capacity, which may not fit bulk-archive or cold-data scenarios.

Four physical CPUs locked to LGA 3647

The system ships with the maximum of four processors already installed; the socket count cannot be expanded beyond this configuration. Buyers needing a smaller starting point with room to add CPUs later should evaluate dual-socket alternatives, while those requiring the highest per-core frequency or newer instruction sets will need a different processor generation altogether.
