DELL PowerEdge R940 3U rack server 4x Xeon Gold 6148 2.4GHz 20-core 512GB DDR4 2x 800GB SSD 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 512 GB of DDR4 registered ECC memory across 48 slots and includes a PERC H730P controller with battery-backed cache. Two 800 GB SATA SSDs and quad-port 1/10 GbE networking are installed. Dual 1600 W platinum power supplies and iDRAC9 Enterprise remote management complete the package.

Upgrade from dual-socket or lower-core platforms

This system replaces dual-socket servers or older four-socket boxes that cannot reach 80 total cores and 6 TB maximum memory capacity. The jump is worth it when workloads such as large in-memory databases, virtualisation clusters or real-time analytics need the full 48 DIMM slots and four-processor scaling in a single 3U chassis. Buyers staying with smaller memory footprints or fewer cores will not use the headroom this platform provides.

Verify rack depth, power feeds and drive count

Confirm the rack can accommodate the chassis depth and that two 1600 W power circuits are available for redundant operation. The front bay holds eight 2.5-inch drives but only two SSDs are included; additional SATA or SAS drives must be sourced separately. Ensure the PERC H730P RAID modes match the planned storage layout and that iDRAC9 Enterprise licensing suits the management strategy.
