DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 6148 2.4GHz 20-Core 128GB DDR4 8x 2.4TB SAS H730P

Four-Socket Xeon Gold Server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. It ships with 128 GB of DDR4 2666 MHz registered ECC memory across 48 available slots and a PERC H730P 2 GB RAID controller managing eight 2.4 TB 10K SAS drives in a 2.5-inch form factor.

Upgrade From Dual-Socket Platforms

Moving to four sockets doubles the core count and memory channels compared with typical dual-socket servers, which matters when workloads scale beyond what two processors can address. The jump is worth it for database consolidation, in-memory analytics or virtualization clusters that need the full 6 TB memory ceiling and 48 DIMM slots populated.

12 Gb/s SAS Backplane Limits

The storage controller and backplane operate at 12 Gb/s SAS, so drive throughput tops out at that link speed regardless of the drive's own rating. The eight 2.5-inch bays are filled with the supplied 2.4 TB hard disks; adding solid-state media later requires SAS or SATA models that fit the same 12 Gb/s interface.
