Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack system built for heavy database, virtualization and analytics workloads. Four Intel Xeon Gold 6142 processors deliver 64 total cores at 2.6 GHz with 3.7 GHz turbo capability. 256 GB of registered DDR4 ECC memory across eight 32 GB modules provides a large footprint for in-memory datasets.

Verify rack space and network needs

Confirm the cabinet can accommodate a 3U chassis and that front-to-rear airflow matches your cooling layout. Two 1600 W redundant power supplies require matching PDU outlets and circuit capacity. The Intel X520/I350 daughter card supplies two 1 GbE and two 10 Gb SFP+ ports — ensure your top-of-rack switches have compatible transceivers and cabling.

Expands within the same chassis

Eight 2.5-inch drive bays are fully populated with 800 GB SATA SSDs behind the PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Forty-eight DIMM slots allow growth to 6 TB of DDR4 memory. iDRAC 9 Enterprise enables remote firmware updates, power cycling and console access without a local KVM. Ready rails and bezel are included for immediate rack integration.

Questions about this item

What comes in the box and what must I source separately?

The server ships with four Xeon Gold 6142 processors, 256 GB DDR4 ECC memory, eight 800 GB SATA SSDs, PERC H730P controller, quad-port 1/10 GbE network card, iDRAC9 Enterprise, two 1600 W PSUs, rails and bezel. No OS or application licences are included.

Should I pick the 256 GB memory configuration or plan for the 6 TB maximum?

The unit arrives with eight 32 GB DDR4-2666 registered ECC modules occupying eight of 48 slots. If your workloads fit in 256 GB you can deploy immediately; the remaining 40 slots allow expansion up to 6 TB when demand grows.

What does the 2.6 GHz base clock with 3.7 GHz turbo mean for real workloads?

Each of the 64 cores runs at 2.6 GHz base and can boost to 3.7 GHz under thermal headroom, giving strong single-thread response for database indexes while sustaining high throughput across all cores for virtualisation or analytics.
