3U Rack Server with Four Xeon Gold CPUs

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. It includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. A PERC H730P controller with 2 GB cache manages the two installed 400 GB SATA SSDs and provides RAID 0, 1, 5, 6, 10, 50 and 60 support. Dual 1600 W redundant power supplies, iDRAC9 Enterprise, quad-port networking and rails are fitted.

Suited for dense four-socket compute.

This server targets workloads that benefit from 64 total cores and a 6 TB memory ceiling in a 3U form factor, such as virtualisation clusters, in-memory databases or high-throughput transaction processing. Organisations needing only one or two sockets, lower core counts or a tower chassis will find the capacity excessive and the rackmount format unsuitable. Buyers who require more than eight 2.5-inch drive bays or a different network interface should evaluate other platforms.

48 DDR4 slots define the memory ceiling

The system board provides 48 DDR4 DIMM slots supporting up to 6 TB of registered ECC memory, so the installed 256 GB can be expanded substantially without replacing the server. The LGA 3647 sockets are already fully populated with the maximum of four processors, so CPU upgrades are not possible. The PERC H730P controller and the eight-bay 2.5-inch backplane set the storage connectivity and drive-count limits for this configuration.

Questions about this item

Does the server include the four Xeon Gold 6142 processors and 256GB DDR4 memory, or must I supply them?

The unit ships with four Xeon Gold 6142 2.6GHz 16-core processors and 256GB DDR4 2666MHz registered ECC memory already installed.

Can the PERC H730P controller manage my existing SATA and SAS drives alongside the two 400GB SSDs?

Yes, the H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 for both SATA and SAS drives, so your current drives can be added to the same array or a separate one.

How do I confirm the iDRAC9 Enterprise remote management is active after first boot?

Connect the dedicated iDRAC network port, then browse to the IP shown on the front LCD; the login screen confirms the Enterprise licence is active.
