Processor and Memory Configuration

This Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules, installed in a platform that supports up to 48 DIMM slots and a maximum capacity of 6 TB.

Storage and Network Capabilities

The server ships with eight 400 GB SATA solid-state drives managed by a Dell PERC H730P 2 GB storage controller supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. A quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections, while iDRAC 9 Enterprise enables remote management. Redundant 1600 W platinum power supplies, rails and a front bezel complete the package.

Workload Suitability

This configuration suits organisations running memory-intensive databases, virtualisation hosts or analytics workloads that benefit from high core counts and large DDR4 capacity within a 3U footprint. Buyers who require more than eight internal drive bays, different storage interfaces or GPU expansion should evaluate other platforms. The installed SATA SSD capacity and controller feature set define the storage ceiling for this unit.

Questions about this item

How do I confirm the four Xeon Gold 6148 processors are all detected and running at 2.4 GHz after installation?

The iDRAC 9 Enterprise interface shows each CPU socket, core count and live clock speed so you can verify all four 20-core chips are present and operating at 2.4 GHz.

Which items ship with the server and which components such as additional drives or memory must be purchased separately?

The box includes the 3U chassis, four Xeon Gold 6148 CPUs, 256 GB DDR4 in eight 32 GB modules, eight 400 GB SATA SSDs, PERC H730P controller, X520/I350 quad-port card, iDRAC 9 Enterprise, two 1600 W PSUs, rails and bezel; extra SSDs or DDR4 DIMMs are not included.

Should I choose this 256 GB DDR4 configuration or add more memory up to the 6 TB maximum?

The system arrives with 256 GB across eight of the 48 DDR4 slots leaving 40 slots free; add registered ECC DDR4 modules in multiples of eight to reach the 6 TB limit if your workload needs more capacity.
