Four-socket Xeon Gold 6148 server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 768 GB of DDR4-2666 registered ECC memory across 24 modules and uses a PERC H730P controller with 2 GB cache to manage eight 600 GB 10K SAS drives. Dual 1600 W platinum power supplies, iDRAC9 Enterprise and a quad-port 1/10 GbE daughter card complete the configuration.

Suited for dense virtualisation

This platform targets organisations that need maximum core count and memory capacity in a 3U footprint, such as virtualisation clusters, in-memory databases or ERP systems. The four-socket design scales to 6 TB of DDR4 across 48 slots, so growth headroom is substantial. Buyers who need GPU compute, more than eight front drive bays or single-thread speeds above the 3.7 GHz turbo should evaluate alternative architectures.

PERC H730P controller with 2 GB cache

The storage subsystem centres on the Dell PERC H730P RAID controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Its 2 GB backed cache enables write-back acceleration for the eight 600 GB SAS drives installed in the 2.5-inch bays. Confirm that your workload fits within this controller’s SAS/SATA lane count and drive-count limit before deployment.

Questions about this item

Will my existing 12 Gb/s SAS cables connect to the PERC H730P controller in this R940?

Yes, the Dell PERC H730P 2 GB controller uses 12 Gb/s SAS ports so standard 12 Gb/s SAS cables will attach directly.

Can the four Xeon Gold 6148 processors share the 768 GB of DDR4 2666 MHz memory installed across the 48 DIMM slots?

Yes, all four CPUs access the full 768 GB through the Intel C620 chipset; the 24× 32 GB registered ECC modules populate 24 of the 48 available slots.

How do I confirm the iDRAC9 Enterprise remote management is active after the server posts?

During boot watch for the iDRAC9 IP address on the LCD panel or press F2 to enter the iDRAC configuration utility and verify the network settings.
