Mission-critical 3U server

This Dell PowerEdge R940 is a 3U rack server built for mission-critical workloads. It ships with four Intel Xeon Gold 6148 processors running at 2.4 GHz with a 3.7 GHz turbo frequency. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Dual 1600 watt redundant power supplies and iDRAC 9 Enterprise remote management are standard.

Database clusters versus smaller deployments

The four-socket design and 48 memory slots suit organisations running heavily threaded databases, virtualisation clusters or in-memory analytics. Buyers who need a lower core count or a smaller memory footprint should consider a two-socket platform. The 3U form factor also requires a compatible rack enclosure with sufficient depth and cooling capacity.

Four-socket Xeon Gold 6148 configuration

The defining specification is the quartet of Xeon Gold 6148 CPUs delivering 20 cores each at 2.4 GHz base clock. This fixed four-processor layout determines the licensing tier, thread density and memory-channel population for the workloads above.

Vragen over dit artikel

Should I pick the four-processor model or look for a two-processor version?

This unit ships with four Xeon Gold 6148 processors already installed, giving the maximum 4-socket configuration the R940 supports.

What does the 2.4 GHz clock speed deliver inside a live server?

Each 20-core Xeon runs at 2.4 GHz base and can reach 3.7 GHz turbo when thermal headroom allows.

How does the 12 Gb/s SAS controller limit real-world drive throughput?

The PERC H730P runs at 12 Gb/s per SAS lane, so the eight 10K drives share that bandwidth through the controller.
