DELL PowerEdge R940 3U rack server 4× Xeon Gold 6130 2.1GHz 16-core 256GB DDR4 2×400GB SSD

Four-socket Xeon server for mission-critical

The Dell PowerEdge R940 is a 3U rack system populated with four Intel Xeon Gold 6130 processors running at 2.10 GHz. Each CPU provides 16 cores, delivering 64 threads in total. The chassis includes 256 GB of DDR4 registered ECC memory across 48 slots and two 400 GB SATA solid-state drives managed by a PERC H730P controller. Dual 10 Gb SFP+ and dual 1 GbE ports plus iDRAC9 Enterprise complete the package.

Verify rack space power and memory expansion plans

Confirm your cabinet can accommodate a 3U rack-mount unit and that the facility provides redundant feeds for the two 1600 W platinum power supplies. The board offers 48 DDR4 slots with a 6 TB ceiling; only eight are occupied today, so decide whether future growth will use the remaining slots or require a different density. The PERC H730P supports SAS and SATA drives with RAID levels up to 60; ensure any additional drives match the 2.5-inch SATA or SAS interface.

Hot-swap bays redundant power

Eight front-accessible 2.5-inch bays support hot-swap replacement without downtime. Redundant 1600 W supplies are also hot-swappable, allowing maintenance while the server stays online. Included ready rails mount the 3U chassis in standard square-hole or round-hole racks, and the front bezel adds physical security for the drive bay. iDRAC9 Enterprise provides dedicated remote console, power control and firmware updates over a separate management network.
