4-Socket 3U Rack Server

The Dell PowerEdge R940 is a 3U rack server fitted with four Intel Xeon Gold 6134 processors running at 3.2 GHz with 8 cores each. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across 8 modules. The chassis provides eight 2.5-inch SAS/SATA drive trays and includes a PERC H730P 2 GB RAID controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 1600 W platinum power supplies, iDRAC9 Enterprise and quad-port networking are included.

Suited for Dense Multi-Socket Workloads

This server targets organisations running memory-intensive databases, virtualisation clusters or ERP systems that benefit from four sockets and up to 6 TB of DDR4 across 48 DIMM slots. The 3U form factor fits standard racks where space is at a premium. Buyers needing GPU compute, more than eight internal drive bays or single-thread frequency above 3.7 GHz turbo should evaluate alternative platforms.

48 DDR4 Slots Define Maximum Capacity

The platform supports a maximum of 6 TB of DDR4 memory through 48 registered ECC slots, with 256 GB installed as 8 × 32 GB modules. This ceiling determines whether the system can accommodate projected dataset growth or consolidated virtual machine counts without a hardware refresh.

Questions about this item

How do I confirm the four Xeon Gold 6134 processors are all detected and running at 3.2 GHz after installation?

Check the iDRAC 9 Enterprise interface or the system BIOS; both will show all four CPUs with 8 cores each at the rated 3.2 GHz base clock and 3.7 GHz turbo.

The listing says 8 drive trays but no drives — which drives must I purchase separately and are any cables included?

You need to buy 2.5" SAS or SATA drives; the H730P controller and backplane cables are already installed, so only the drives themselves are required.

The server has 48 memory slots and 256 GB installed — should I add 32 GB or 64 GB DDR4 modules to reach the 6 TB maximum?

The installed memory uses 8× 32 GB DDR4 2666 MHz RDIMMs; adding matching 32 GB modules is the simplest way to scale toward the 6 TB limit.
