Four-Socket Xeon Server for Dense Compute

The Dell PowerEdge R940 packs four Xeon Gold 6142 processors, each with 16 cores at 2.6 GHz, into a 3U rack chassis. It ships with 128 GB of DDR4 registered ECC memory across 48 slots and a PERC H730P controller driving eight 300 GB 10K SAS drives. Redundant 1600 W platinum power supplies and iDRAC9 Enterprise management complete the package.

Suits High-Thread Workloads.

This system targets virtualisation hosts, in-memory databases and multi-threaded analytics that benefit from 64 total cores and large memory capacity. The quad-port X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ links for network segmentation. Buyers who need GPU acceleration or all-flash arrays should evaluate other platforms.

64 Cores at 2.6 GHz Base Decide Fit

The decisive specification is the combined 64 cores running at a 2.6 GHz base frequency with 3.7 GHz turbo across four sockets. Workloads that scale across many threads will use this capacity; single-threaded tasks or licence-constrained software tied to core counts may not justify the density.

Questions about this item

What rack space and power circuits must be available to install this 3U server with dual 1600 W supplies?

The chassis occupies 3U of rack height and includes redundant hot-swap 1600 W power supplies, so two compatible PDU circuits are required for full redundancy.

Can the PERC H730P controller manage the existing 300 GB 10K SAS drives together with larger SATA drives I may keep?

Yes, the H730P supports mixed SAS and SATA drives in RAID 0, 1, 5, 6, 10, 50 or 60, allowing the installed 300 GB SAS disks to share arrays with additional SATA capacity.

How can I confirm the four Xeon Gold 6142 processors and 128 GB of DDR4 are recognised after first boot?

Open the iDRAC9 Enterprise interface or enter the system BIOS; both will display four CPUs at 2.6 GHz with 3.7 GHz turbo and 128 GB of registered ECC DDR4 memory.
