DELL PowerEdge R940 3U rack server 4× Xeon Gold 6148 2.4GHz 20-core 768GB DDR4 8× 600GB SAS H730P

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.
