Mission-critical compute platform

The Dell PowerEdge R940 is a 3U rack server built for workloads that demand high core counts and large memory capacity. Four Intel Xeon Gold 6134 processors deliver 32 total cores at 3.2 GHz with 3.7 GHz turbo. The system ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules. Eight 1.2 TB 10K SAS drives connect through a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60.

Ideal for dense virtualisation

This configuration suits organisations running virtualised environments, large-scale ERP or real-time analytics that benefit from four-socket scaling and 768 GB of installed memory. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links for flexible fabric connectivity. Buyers who need more than 48 memory slots or more than eight 2.5-inch drive bays should consider a different chassis.

Four-socket Xeon Gold 6134 at 3.2 GHz

The decisive specification is the four Intel Xeon Gold 6134 processors, each with eight cores at 3.2 GHz base frequency. This fixed CPU configuration sets the performance ceiling for all workloads on the platform. Memory can expand to 6 TB across 48 slots, but the processor count and model cannot be changed after purchase.

Questions about this item

How do I install the four Xeon Gold 6134 processors into the LGA 3647 sockets, and which step do people often get wrong?

Align each processor using the socket notches, lower it straight down without forcing, then close the load plate and torque the retention screws in a cross pattern; the step often missed is applying the supplied thermal interface material evenly before seating the heatsink.

What maintenance or replacement will the PERC H730P controller's battery-backed cache need later?

The 2 GB cache module includes a lithium-ion battery that typically lasts three to five years; when the iDRAC 9 Enterprise reports a battery degradation alert, replace the cache module to preserve write-back performance.

What limit appears first when the eight 1.2 TB 10K SAS drives sustain heavy random writes?

The 12 Gb/s SAS backplane and H730P controller can saturate at the drives' combined sequential throughput, so sustained random write IOPS hit the mechanical 10K RPM latency ceiling before the controller or bus becomes the bottleneck.
