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.

Questions about this item

Does the server ship with the two 400 GB SATA SSDs already installed or must I buy drives separately?

The unit includes two Dell Enterprise 400 GB SATA 6 Gb/s 2.5-inch SSDs pre-installed in the 8-bay chassis; additional drives are optional.

Should I choose the four-processor Xeon Platinum 8160 configuration or a lower processor count for this R940?

The system is already populated with the maximum of four Xeon Platinum 8160 processors, each 24 cores at 2.1 GHz with 3.7 GHz turbo, so no lower-count option exists for this build.

What does the 512 GB DDR4 2666 MHz memory figure mean for actual workloads on this machine?

It provides 16 registered ECC DIMMs of 32 GB each filling 16 of 48 slots, leaving 32 slots free to expand toward the 6 TB maximum for larger datasets.
