Four-socket Xeon server for mission-critical

The Dell PowerEdge R940 packs four Intel Xeon Gold 6134 processors, each with eight cores running at 3.2 GHz and a 3.7 GHz turbo frequency. With 256 GB of DDR4 2666 MHz registered ECC memory installed across 48 slots, it targets organisations that need high core counts and large memory capacity in a 3U rack form factor. The system supports up to 6 TB of total memory for future expansion.

Sustained load behaviour with redundant power

Four processors and a Dell PERC H730P 2 GB controller with battery-backed cache drive eight 1.2 TB 10 K SAS drives in RAID 0, 1, 5, 6, 10, 50 or 60. Dual 1600 W platinum power supplies share the load, so the platform maintains performance during prolonged compute or storage tasks without throttling from a single supply failure. The Intel C620 chipset coordinates I/O across all sockets.

Thermals, noise and power in normal use

Hot-swap redundant power supplies and the 3U chassis airflow design keep component temperatures stable under typical datacentre conditions. The integrated Intel X520/I350 network daughter card provides two 1 GbE and two 10 Gb SFP+ ports for balanced throughput. iDRAC 9 Enterprise enables remote thermal monitoring and power management without requiring physical access to the rack.

Questions about this item

How much heat and power draw should I expect from the four Xeon Gold 6134 CPUs and dual 1600 Watt PSUs running continuously?

The four Xeon Gold 6134 processors each have a 3.2 GHz base clock and 3.7 GHz turbo, while the redundant 1600 Watt platinum power supplies deliver efficient power conversion under sustained load.

Which caddies, cables or rails are required to install the 2.5-inch SAS drives and connect the X520/I350 network card?

The server includes ready rails and a front bezel; the eight 1.2 TB SAS drives ship installed in the 2.5-inch bays and the quad-port X520/I350 daughter card occupies a dedicated internal slot.

Can I keep my existing DDR4 2666 MHz ECC modules and PERC H730P controller when moving to this R940?

The system uses 256 GB of DDR4 2666 MHz registered ECC memory across 48 slots and a PERC H730P 2 GB SAS controller, so compatible DDR4 ECC modules and the same controller generation will work.
