Mission-critical 3U rack server

The Dell PowerEdge R940 is a 3U rack-mounted server system built for mission-critical workloads. It ships new with four Intel Xeon Gold 6134 processors, each running at 3.2 GHz with eight cores and a 3.7 GHz turbo frequency. The system includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules and uses the Intel C620 chipset on an LGA 3647 platform.

Suited for dense compute, not for smaller racks

This server suits organisations that need maximum processor density and memory capacity in a 3U footprint with redundant 1600 W platinum power supplies. Buyers who require a 1U or 2U form factor, fewer than four sockets, or a lower entry memory configuration should evaluate other platforms. The eight 2.5-inch drive bays are populated with 2.4 TB 10K SAS drives behind a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60.

768 GB DDR4 across 48 slots decides fit

The single specification that determines suitability is the 768 GB DDR4 2666 MHz registered ECC memory installed across 48 DIMM slots with a 6 TB maximum capacity. This memory configuration and expansion ceiling dictate whether the server matches the application footprint and future growth requirements.

Questions about this item

What SAS speed does the PERC H730P controller support for the 2.4TB drives?

The PERC H730P is a 12Gb/s SAS controller, so the eight 2.4TB drives connect at up to 12Gb/s each.

What physical space and rails are required to mount this 3U server?

The system is a 3U rack unit that ships with Ready Rails for tool-less installation in standard square-hole or round-hole 4-post racks.

How is the 768GB of DDR4 memory installed across the 48 slots, and what mistake should be avoided?

Memory is populated as 24 x 32GB DDR4 2666MHz registered ECC DIMMs; install in matched sets per processor to avoid reduced performance or boot failure.
