DELL PowerEdge R940 3U rack server 4× Xeon 8160 2.1 GHz 24-core 512 GB DDR4 2× 400 GB SSD H730P

Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Platinum 8160 processors. Each CPU delivers 24 cores at 2.1 GHz with a 3.7 GHz turbo frequency. The system ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots and includes a PERC H730P 2 GB storage controller plus two 400 GB SATA SSDs.

Suits dense compute; not for wider memory

This configuration targets workloads that benefit from high core density in a compact chassis, such as virtualization clusters or in-memory databases. The board provides 48 total DIMM slots with a 6 TB ceiling, so buyers who need more than 48 slots must evaluate alternative platforms. Only two 2.5-inch drive bays are populated, leaving limited room for additional internal storage without expansion shelves.

48 DIMM slots and 6 TB maximum memory

The single specification that decides fit is the memory architecture: 48 DDR4 slots supporting up to 6 TB of registered ECC capacity. If the application requires more slots or a higher total memory limit, this server cannot meet the requirement.
