Dell PowerEdge R940 3U Rack Server

The Dell PowerEdge R940 is a 3U rack server built for dense compute workloads. Four Intel Xeon Gold 6142 processors deliver 64 cores at 2.60 GHz with 3.7 GHz turbo. The system ships with 64 GB DDR4 registered ECC memory across 48 slots and a PERC H730P 2 GB SAS controller supporting RAID 0, 1, 5, 6, 10, 50, 60.

Suits four-socket density needs.

This server fits buyers who need four-socket density in 3U with redundant 1600 W power supplies, quad-port 1 GbE and 10 Gb SFP+ networking, and iDRAC9 Enterprise remote management. It does not suit workloads that rely on high single-thread frequency or GPU acceleration, and the two installed 300 GB 10 K SAS drives leave six 2.5 inch bays empty for additional storage.

48 DDR4 slots and PERC H730P controller decide fit

The 48 DDR4 slots supporting up to 6 TB registered ECC memory and the PERC H730P 12 Gb/s SAS controller with 2 GB cache define whether this chassis matches the memory capacity and RAID level required. The LGA 3647 socket and Intel C620 chipset lock the platform to the installed Xeon Gold 6142 processors.

Questions about this item

What rack space and power connections must already be available to install this 3U server with dual 1600 W PSUs?

You need 3U of free rack height and two PDU outlets that can each supply a 1600 W power supply.

Can the PERC H730P controller manage the two installed 300 GB SAS drives together with older SATA disks I might add?

Yes, the H730P supports both SAS and SATA drives and can include them in the same RAID arrays.

How can I confirm the four Xeon Gold 6142 processors and 64 GB of DDR4 memory are all recognised after first boot?

Open the iDRAC9 Enterprise interface or the system BIOS; both will show four CPUs, 16 cores each, and 64 GB total memory.
