Four-socket Xeon Platinum 8160 server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Platinum 8160 processors. Each CPU runs at 2.1 GHz with 24 cores and a 3.7 GHz turbo frequency. The system ships with 64 GB of DDR4 2666 MHz registered ECC memory across 48 available slots.

Suited for dense compute workloads

This server fits environments that need maximum processor density in a 3U footprint, such as virtualisation hosts, database clusters or high-performance computing nodes. Buyers who require installed storage drives, GPU acceleration or a smaller rack profile should consider other configurations.

48 DDR4 memory slots for 6 TB maximum

The platform provides 48 DIMM slots supporting up to 6 TB of DDR4 registered ECC memory. This capacity ceiling determines whether the R940 can meet your application's memory footprint before you commit to the chassis.

Questions about this item

Should I pick the 64 GB configuration or add more DDR4 modules?

The system ships with 64 GB across four 16 GB DDR4 2666 MHz registered ECC DIMMs and has 48 slots supporting up to 6 TB, so you can expand later if workloads grow.

What does the 3.7 GHz turbo figure mean for actual performance?

Each Xeon Platinum 8160 can boost from 2.1 GHz to 3.7 GHz on active cores, giving higher single-thread speed for bursty tasks while all 24 cores run at base clock under sustained load.

How does the PERC H730P controller limit storage speed?

The H730P provides 12 Gb/s SAS/SATA connectivity with RAID 0/1/5/6/10/50/60 and pass-through, capping drive throughput at the controller’s 12 Gb/s link.
