Dual-socket 1U rack server

The PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each. It delivers 768 GB of DDR4 registered ECC memory across 24 slots. The platform targets dense scale-out workloads such as virtualization clusters, database nodes and high-performance computing farms.

Storage and networking foundation

A PERC H730P controller with 2 GB cache manages the two installed 800 GB SATA SSDs and supports RAID 0, 1, 5, 6, 10, 50 and 60. The quad-port network daughter card provides two 1 GbE ports and two 10 Gb SFP+ connections for flexible uplink options. Dual redundant 750 W platinum power supplies keep the system running during a unit failure. Buyers who need more than eight 2.5-inch drive bays or a different drive interface cannot use this chassis.

Remote management and physical kit

iDRAC 9 Enterprise enables full out-of-band control, firmware updates and console redirection over the network. The shipment includes ready rails for quick rack mounting and a front bezel for a clean appearance. No operating system, hypervisor licences or additional drive caddies are bundled. Administrators who require a built-in GPU or fibre-channel connectivity must add those separately.

Questions about this item

How much memory can I add before hitting the 3TB ceiling of this R640?

The system ships with 768GB across 24 DDR4 slots and supports up to 3TB total capacity.

What thermal and acoustic load should I expect from dual Xeon Gold 5118 CPUs and two 750 W platinum PSUs in a 1U rack?

Dual 12-core processors and redundant platinum power supplies run in a 1U chassis with integrated high-speed fans designed for sustained data-centre workloads.

Which rack-mount hardware and network cabling do I need to have on hand before the server arrives?

Ready Rails and a front bezel are included; you supply the rack, SFP+ modules or copper cables for the X520/I350 quad-port card, and power cords for the dual PSUs.
