Mission-critical compute density

The Dell PowerEdge R940 is a 3U rack server populated with 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 128 GB of DDR4 registered ECC memory across eight modules. It targets organisations running heavy virtualisation, in-memory databases or high-performance analytics that demand maximum core count in a compact footprint.

Storage and networking practical limits

The onboard Dell PERC H730P controller manages the two installed 400 GB SATA SSDs and supports RAID 0, 1, 5, 6, 10, 50 and 60. The chassis provides eight 2.5-inch drive bays using a SATA interface; SAS drives are also supported by the controller. Network connectivity comes from a quad-port daughter card offering two 1 GbE and two 10 Gb SFP+ ports. Remote management is handled by iDRAC 9 Enterprise.

Pre-installation checklist

Verify that your rack can accommodate a 3U unit with the included ready rails. Confirm the facility can supply two redundant 1600 watt power supplies with the required connectors. Ensure the operating system and hypervisor versions support the Intel C620 chipset and the installed Xeon processors. Plan memory expansion using DDR4 registered ECC modules only; the platform provides 48 slots with a 6 TB maximum capacity.

Questions about this item

Should I choose the 128 GB DDR4 configuration or plan for the 6 TB maximum capacity?

The system ships with 128 GB across 8 slots; the board has 48 slots total and supports up to 6 TB of DDR4 registered ECC memory when all slots are populated.

What does the 2.1 GHz base clock with 3.7 GHz turbo mean for sustained workloads on four Xeon Platinum 8160 processors?

Each of the four 24-core CPUs runs at 2.1 GHz base and can boost to 3.7 GHz; sustained performance depends on cooling and power limits in the 3U chassis.

How does the PERC H730P 12 Gb/s SAS/SATA controller cap drive performance with the installed 400 GB SATA SSDs?

The controller supports 12 Gb/s SAS and 6 Gb/s SATA; the two 400 GB SATA SSDs will be limited to the SATA 6 Gb/s link speed.
