Quad-socket Xeon server for dense compute

The Dell PowerEdge R940 fits four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores, into a 3U rack chassis. Sixty-four gigabytes of DDR4 registered ECC memory occupy four of the forty-eight available slots. Eight 800 GB SATA solid-state drives connect through a PERC H730P controller with 2 GB cache and battery backup. Dual 1600 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and sliding rails complete the package.

Suits workloads needing many cores in 3U

Database clusters, virtualisation hosts and analytics platforms that scale across eighty threads benefit from the four-socket layout and large memory ceiling. Buyers who need more than sixty-four gigabytes of RAM or additional drive bays should look at a larger configuration. Organisations without rack infrastructure or requiring GPU acceleration will not find those features here.

Four Xeon Gold 6148 CPUs define the performance

Each processor delivers twenty cores at 2.4 GHz with a 3.7 GHz turbo frequency on the LGA 3647 platform. The installed sixty-four gigabytes of DDR4 can be expanded to six terabytes across forty-eight slots. Matching the CPU count and memory capacity to the application licence model is the primary sizing decision.

Questions about this item

Should I choose the 4-processor configuration with 64 GB DDR4 or add more memory modules later?

The server arrives with four Xeon Gold 6148 CPUs and 64 GB across four 16 GB DDR4 DIMMs, leaving 44 empty slots for expansion up to 6 TB total.

What does the 2.4 GHz base clock with 3.7 GHz turbo mean for real workloads?

Each 20-core processor runs at 2.4 GHz sustained and can boost to 3.7 GHz on active cores, giving high single-thread speed when needed while keeping 80 threads available for parallel tasks.

How does the PERC H730P controller limit the eight 800 GB SATA SSDs?

The H730P provides 12 Gb/s SAS/SATA connectivity with 2 GB cache and battery backup, so the SATA 6 Gb/s SSDs operate at their native interface speed while supporting RAID 0, 1, 5, 6, 10, 50 and 60.
