Four-socket Xeon Gold 6142 server

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. It ships with 768 GB of DDR4-2666 registered ECC memory across 24 modules and includes a PERC H730P controller with 2 GB cache driving eight 1.2 TB 10K SAS drives. Dual 1600 W platinum power supplies, iDRAC 9 Enterprise, quad-port 1/10 GbE networking, rails and bezel complete the package.

Suits dense virtualisation and in-memory workloads

Organisations consolidating heavy virtual machines, large databases or real-time analytics onto a single 3U chassis will benefit from the 64 total cores and 6 TB maximum memory capacity. Buyers who need more than four processor sockets, direct GPU acceleration or storage interfaces beyond SAS and SATA should evaluate alternative platforms. The fixed 3U height and four-socket ceiling also limit future vertical scaling within the same enclosure.

6 TB DDR4 memory ceiling

The platform supports up to 6 TB of DDR4 across 48 DIMM slots, making maximum memory capacity the decisive specification for capacity planning. The current 768 GB configuration uses half the sockets, leaving headroom for growth without adding servers. If the target workload demands more than 6 TB of system memory, this architecture cannot meet the requirement.

Preguntas sobre este artículo

What CPUs and memory must already be installed for the four Xeon Gold 6142 processors and 768 GB DDR4 to operate?

The system ships with four Xeon Gold 6142 2.6 GHz 16-core CPUs and 768 GB DDR4 2666 MHz registered ECC memory across 24 slots, so no additional processors or DIMMs are required for basic operation.

Can the PERC H730P controller and SAS drives work with older SATA drives I might keep?

The PERC H730P supports SAS and SATA drives in RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes, allowing existing 2.5" SATA SSDs or HDDs to be added alongside the eight 1.2 TB 10K SAS drives.

How do I verify the iDRAC9 Enterprise remote management is working after setup?

Connect the dedicated iDRAC network port, log in via its IP address, and confirm the dashboard shows all four CPUs, 768 GB memory, eight SAS drives, dual 1600 W power supplies and network daughter card without errors.
