Ready-to-Deploy Rack Server

The Dell PowerEdge R640 arrives as a 1U rack-mount system with a single Xeon Silver 4210 processor running at 2.2 GHz and 128 GB of DDR4 ECC registered memory. It targets IT teams that need a verified compute node for virtualization or database workloads without waiting for a custom build.

Controller and Network Extras

A PERC H740P RAID controller manages up to eight 2.5-inch SATA drive bays, while a dual-port 10 GbE 562T adapter provides high-throughput networking. The iDRAC9 Enterprise licence enables full remote console, power control and firmware updates from anywhere.

Installation Notes

The chassis measures 36 by 24 by 10 inches and weighs 40 pounds, so two-person handling or a lift is standard practice. Drive caddies are not included, and the 750 W power supplies use a proprietary form factor that may require the matching rail kit for secure rack mounting.

Questions about this item

What DDR4 memory modules will be needed when expanding the 128 GB beyond the current capacity?

The system uses DDR4 ECC registered DIMMs; it supports up to 7.68 TB total across 24 slots, so additional DDR4 ECC registered modules are required for any expansion.

Which component reaches its limit first when the Xeon Silver 4210 runs at 2.2 GHz continuously under full load?

The 10-core Xeon Silver 4210 with 13.75 MB cache will hit its thermal and power ceiling before the PERC H740P controller or the dual 750 W supplies become the bottleneck.

How loud and hot does the R640 get with both 750 W power supplies running 24/7?

Dual 750 W supplies and the 10-core CPU generate significant heat; the 1U chassis relies on high-speed fans that produce noticeable noise in a typical office environment.
