Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built for workloads that demand four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 512 GB of DDR4 registered ECC memory across 16 modules and eight 2.4 TB 10K SAS drives managed by a PERC H730P controller. Dual 1600 W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management.

Verify rack space and network needs

Confirm that your rack can accommodate a 3U chassis and that the facility can supply power for two 1600 W units. The included network daughter card delivers two 1 GbE ports and two 10 Gb SFP+ ports, so ensure your top-of-rack switches have matching SFP+ transceivers and cabling. The system uses an LGA 3647 socket and Intel C620 chipset with 48 DIMM slots, allowing future memory expansion up to 6 TB.

Included accessories simplify deployment

Sliding ready rails and a front bezel are supplied, reducing installation time in standard racks. The PERC H730P’s 2 GB cache and battery-backed write cache enable RAID 0, 1, 5, 6, 10, 50 and 60 without extra hardware. iDRAC9 Enterprise licenses advanced remote console, virtual media and automation features out of the box, so no separate management module is required.

Questions about this item

Does the server ship with all 8 drive bays populated, or do I need to buy additional 2.5-inch SAS drives?

The unit includes eight 2.4 TB 10K SAS drives, filling every 2.5-inch bay, so no extra drives are required for a full configuration.

Should I choose the 512 GB DDR4 configuration or add more memory up to the 6 TB maximum?

The system arrives with 16 modules of 32 GB DDR4 2400 MHz ECC, leaving 32 empty slots; add memory later only if your workloads exceed the installed 512 GB.

What throughput can the PERC H730P controller deliver with the eight 2.4 TB SAS drives in RAID?

The H730P 12 Gb/s SAS controller supports RAID 0, 1, 5, 6, 10, 50 and 60, letting the eight 10K drives sustain multi-gigabyte sequential speeds for database and virtualization workloads.
