Mission-critical 3U server for four-socket workloads

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6130 processors running at 2.1 GHz with 16 cores each. It ships with 512 GB of DDR4 registered ECC memory across 16 DIMM slots and two 400 GB SATA SSDs managed by a PERC H730P RAID controller. This configuration targets databases, virtualization hosts and analytics platforms that demand high core counts and large memory capacity in a compact rack footprint.

Tool-less rail installation with hot-swap components

The server includes ready rails and a front bezel for rapid rack mounting without tools. All four CPUs, the memory risers and the storage controller are pre-installed, so the only on-site steps are seating the SSDs in the hot-swap bays and connecting power and networking. The primary risk is exceeding the 48-slot memory limit when expanding beyond the factory 512 GB; the board supports up to 6 TB but only with approved DDR4 2666 MHz registered ECC modules.

Sustained throughput from redundant platinum power

Dual 1600 W platinum-efficiency power supplies share the load evenly, keeping voltage stable during prolonged compute bursts. The Xeon Gold 6130 chips maintain a 3.7 GHz turbo frequency across all 16 cores as long as thermal headroom exists, and the H730P controller’s 2 GB battery-backed cache absorbs write spikes without throttling. Workloads that saturate memory bandwidth or drive queues for hours will see consistent performance rather than thermal or power-related drops.

Questions about this item

How can I verify the server is operating correctly after installation?

Check the iDRAC9 Enterprise interface for green health indicators on all four Xeon Gold 6130 processors, 512GB DDR4 memory, PERC H730P controller, and dual 400GB SSDs.

What components are included and what must I purchase separately?

The unit ships with 4x Xeon Gold 6130 CPUs, 512GB DDR4 ECC RAM, PERC H730P controller, 2x 400GB SATA SSDs, X520/I350 network card, iDRAC9 Enterprise, 2x 1600W PSUs, rails, and bezel. Additional drives or memory are optional.

Which memory capacity should I select for this configuration?

The system arrives with 512GB DDR4 2666MHz ECC registered memory across 16 slots. You can expand up to 6TB using the remaining 32 DDR4 slots if your workload requires more capacity.
