DELL PowerEdge R940 3U rack server 4x Xeon Gold 6148 2.4GHz 20-core 128GB DDR4 8x 1.2TB SAS H730P

Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built for mission-critical workloads that demand four-socket density. It ships with four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The system includes 128 GB of DDR4 registered ECC memory across 48 available slots. This configuration targets databases, virtualization clusters, and real-time analytics.

128 GB DDR4 in 48 slots

The single specification that decides fit is the installed memory: 128 GB of DDR4 2666 MHz registered ECC modules populate eight of the 48 DIMM slots. The platform supports a maximum capacity of 6 TB when fully loaded. Buyers who need more memory headroom at purchase must plan for additional modules; the current amount suits moderate consolidation but not large in-memory datasets.

H730P RAID and quad-port networking

The PERC H730P controller with 2 GB cache enables RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes across the eight 1.2 TB 10K SAS drives. A quad-port Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ connections for flexible uplinks. iDRAC 9 Enterprise provides full out-of-band management, while dual 1600 W platinum power supplies and included rails complete the deployment kit.
