Four-socket Xeon server for dense compute

The Dell PowerEdge R940 packs four Intel Xeon Gold 5118 processors, each with 12 cores running at 2.3 GHz and a 3.2 GHz turbo frequency. That delivers 48 total cores in a 3U rack form factor, suited for virtualization hosts, database clusters or high-throughput batch workloads that benefit from high core density in limited rack space.

Controller, networking

A PERC H730P controller with 2 GB cache enables RAID 0, 1, 5, 6, 10, 50 and 60 across the eight 2.5-inch drive bays. Two 400 GB SATA SSDs are installed. The Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise provides out-of-band remote management. Dual 1600 W platinum power supplies, rails and a front bezel complete the bundle.

Verify rack depth, power

The 3U chassis requires a rack deep enough for its full length and circuits capable of feeding redundant 1600 W supplies at your voltage. Memory uses DDR4 registered ECC DIMMs; 256 GB occupies 8 of 48 slots, leaving room to scale toward the 6 TB maximum. Ensure your networking patch panels support SFP+ transceivers for the 10 Gb links.

Perguntas sobre este artigo

How often will the H730P controller's battery need replacement?

The PERC H730P includes a 2GB cache with battery backup; battery life varies by workload and temperature, so plan on periodic checks during routine server maintenance.

What thermal limit appears first when all four Xeon Gold 5118 CPUs run at 3.2GHz turbo continuously?

Sustained 3.2GHz turbo across 48 cores will hit the 1600W redundant PSU capacity and chassis airflow limits before CPU thermal throttling engages.

How loud are the fans when the R940 runs 24/7 with 256GB DDR4 and both 400GB SSDs active?

Expect data-centre grade fan noise; the 3U chassis uses high-speed redundant fans that ramp with inlet temperature and CPU load, making it unsuitable for quiet office spaces.
