Four-Socket Xeon Gold 5118 Server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5118 processors running at 2.3 GHz with twelve cores each. It ships with 128 GB of DDR4 registered ECC memory across forty-eight slots and a PERC H730P controller driving eight 300 GB 10K SAS drives. Redundant 1600 W platinum power supplies and iDRAC9 Enterprise remote management are included.

Suits dense compute, not GPU

This system targets workloads that benefit from forty-eight cores and large memory capacity in a compact rack footprint, such as virtualization hosts, in-memory databases or high-performance computing nodes. Buyers who need GPU acceleration, more than eight 2.5-inch drive bays, or a tower form factor should look elsewhere.

Four-processor LGA 3647 limit defines expandability

The motherboard supports a maximum of four processors and all four sockets are already populated with Xeon Gold 5118 CPUs, so no further CPU upgrades are possible without replacing the installed chips. Memory can still scale to 6 TB using the remaining DDR4 slots.

Questions about this item

Do I need to supply my own SFP+ transceivers for the 10 GbE ports on the X520/I350 card?

The X520/I350 daughter card provides two 10 Gb SFP+ ports; transceivers and cables are not included, so you must supply compatible SFP+ modules for each 10 Gb link.

Can I keep my existing SAS drives and add them to the PERC H730P controller?

Yes, the PERC H730P supports both SAS and SATA drives, so any existing 2.5" SAS or SATA disks can be added to the eight drive bays alongside the installed 300 GB SAS drives.

How do I verify the iDRAC9 Enterprise remote management is active after first boot?

Connect a management network cable to the dedicated iDRAC port, power on the server, and during POST press the indicated key to enter the iDRAC configuration utility where the Enterprise licence status and network settings are displayed.
