Four-Socket 3U Rack Server

The Dell PowerEdge R940 is a 3U rack-mounted server system built for compute-intensive workloads. It carries four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. A PERC H730P controller with 2 GB cache manages the eight installed 800 GB SATA SSDs.

Suited For Dense Multi-Threaded Tasks

This configuration fits environments that need high core counts and large memory capacity in a compact rack footprint. The four-socket design and 48 DIMM slots support up to 6 TB of DDR4 for in-memory databases or virtualization clusters. Buyers who require more than eight 2.5-inch drive bays or a different drive interface should look elsewhere. The fixed four-processor maximum also means no future CPU expansion beyond the installed Gold 6148 chips.

PERC H730P RAID Controller Decides Fit

The storage subsystem centres on the Dell PERC H730P 2 GB controller, which provides 12 Gb/s SAS and SATA connectivity with battery-backed cache. It supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode for the eight 800 GB SATA SSDs. If the application demands a different RAID feature set, a non-RAID HBA or a controller with a higher cache tier, this server will not meet that requirement.

Questions about this item

How many CPU cores are available across the four Xeon Gold 6148 processors installed in this R940?

Each processor has 20 cores, so the four installed CPUs provide a total of 80 cores for workloads.

What is the rated wattage and efficiency level of the redundant power supplies included with this server?

Two 1600 Watt Platinum efficiency hot-swap power supplies are included for redundant operation.

Which memory generation and form factor must already be populated in the 48 DIMM slots for this system to boot?

The server uses DDR4 registered ECC DIMMs; 256 GB (8 × 32 GB) at 2666 MHz is already installed.
