Dell PowerEdge R940 3U Rack Server
The Dell PowerEdge R940 is a 14th Generation four-socket 3U rack server with the most PCIe expansion of any 14G PowerEdge — up to 13 PCIe Gen 3 slots. It supports up to four Intel Xeon Scalable processors with 112 cores total, 48 DDR4 DIMM slots with up to 6 TB of memory, and up to 24x 2.5-inch drives with NVMe support.
Enterasource offers the R940 configured to order. Each server is tested through our multi-point hardware diagnostic process and backed by a 2-year Enterasource warranty.
The R940 is designed for mission-critical database workloads — Oracle RAC, SQL Server Always On, and SAP HANA — where maximum PCIe expansion for add-in cards (HBAs, NICs, accelerators) is as important as raw compute. Its 3U form factor provides more expansion than the 2U R840 while sharing the same four-socket platform.

Frequently Asked Questions
How many PCIe slots does the Dell R940 have?
Up to 13 PCIe Gen 3 slots — the most of any 14th Generation Dell PowerEdge server. This makes the R940 the platform of choice for workloads requiring extensive add-in card expansion.
What is the difference between the Dell R940 and R840?
Both are four-socket servers with 112 max cores and 6 TB RAM. The R940 is 3U with 13 PCIe slots but up to 12 NVMe direct-attach. The R840 is 2U with up to 24 NVMe direct-attach but fewer PCIe slots. Choose R940 for PCIe expansion, R840 for NVMe density and rack efficiency.
What generation is the Dell R940?
The Dell PowerEdge R940 is a 14th Generation (14G) four-socket 3U server using Intel Xeon Scalable processors.
How much does a refurbished Dell R940 cost?
Pricing depends on processor count, memory capacity, storage, and PCIe card requirements. Enterasource builds every R940 to order with a 2-year warranty and free ground shipping to the lower 48 states.
