Dell PowerEdge R640 4LFF dual Xeon Silver 4116
The Dell PowerEdge R640 is a 1U rack server built for dense compute workloads. Two Intel Xeon Silver 4116 processors at 2.1 GHz deliver 24 cores total. The chassis supports up to four 3.5-inch drive bays. It ships with 256 GB of DDR4 ECC registered memory and no storage drives installed.
PERC H740P RAID controller and 10 GbE adapter
The installed PERC H740P hardware RAID controller manages SATA drives in the four-bay backplane. A dual-port 10 GbE 562T network adapter provides high-throughput connectivity. Remote management runs on iDRAC9 with an Enterprise licence for full lifecycle control. Dual 750 W power supplies are included for redundancy.
Rail kit optional and firmware pre-updated
The unit arrives with BIOS and firmware updated to the latest stable release after full diagnostics and burn-in testing. A rail kit is available on request but not included by default. Buyers who need drives, additional memory up to 7.68 TB, or a different CPU configuration must specify those changes before shipment.

Questions about this item
Will the PERC H740P RAID controller need a battery or capacitor replacement later?
The PERC H740P controller uses a backup module that typically lasts several years; replacement is only required if the module fails or reaches end-of-life.
What limits the 2x Xeon Silver 4116 CPUs at 2.1GHz during sustained all-core workloads?
The 12-core processors share a 16.5MB cache and are capped by the dual 750W power supplies and chassis airflow under continuous load.
How much heat and noise do the dual 750W supplies and 2.1GHz CPUs produce when running 24/7?
Two 750W units and the 2.1GHz Xeon pair generate significant heat; fan speeds rise to maintain thermal limits, increasing audible noise in a rack.
