Purpose-built rack server

The Dell PowerEdge R640 is a 1U rackmount server equipped with two Intel Xeon Gold 6148 processors delivering 40 cores total at 2.40GHz. It ships with 256GB of DDR4 memory and an H730P storage controller. The chassis provides eight 2.5-inch drive bays and includes rails and a front bezel for immediate rack deployment. Integrated iDRAC9 Enterprise enables remote management.

Check compatibility first

Verify that your rack accepts standard 1U depth and that the LGA3647 socket processors match any existing maintenance contracts or firmware baselines. The server arrives without an operating system or storage drives, so plan for OS licensing and drive procurement before deployment. Maximum memory capacity reaches 3TB across the available slots, so confirm DIMM population rules if you intend to expand beyond the installed 256GB.

Enterprise-grade construction

The unit weighs 60 kilograms and features front-panel LEDs for power, Ethernet, and USB status. Eight hot-plug 2.5-inch bays allow drive changes without downtime, while the included H730P controller supports hardware RAID for data protection. Rack rails and bezel are supplied, simplifying installation in standard cabinets. Integrated graphics handle console output without a discrete GPU.
