Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 is a 1U rack server built for data-centre workloads that demand dense storage and remote manageability. It ships with one Intel Xeon 5118 processor running at 2.3GHz and 128GB of DDR4 ECC registered memory. The chassis provides four 3.5-inch drive bays ready for SATA hard drives. Integrated iDRAC9 Enterprise remote management allows full out-of-band control.

Sustained load behaviour

Dual 750W power supplies feed the system so it can maintain performance during extended compute or storage tasks. The PERC H740P RAID controller supports hardware RAID across the four drive bays, keeping throughput steady under heavy I/O. A 10GbE dual-port 562T adapter delivers consistent network bandwidth for virtualisation or database traffic. Firmware and BIOS are updated to the latest stable release before dispatch.

Deciding specification

The four 3.5-inch drive bays set the storage ceiling; buyers who need more internal drives must choose a different chassis. Only one Xeon 5118 is installed, though the board accepts a second processor for added cores. Maximum memory capacity reaches 7.68TB when all DIMM slots are populated. No drives are included, so storage must be sourced separately.

Questions about this item

How loud and hot does the R640 run with two 750 W power supplies under continuous load?

The system ships with dual 750 W supplies; fan speed and thermal output scale with the actual workload and ambient temperature.

Which drive trays and cables do I need to populate the four 3.5-inch bays?

The chassis accepts four 3.5-inch SATA drives; trays and data cables are not included and must be sourced separately.

Can I keep using my current 10 GbE 562T adapter when I add a second Xeon 5118?

The 10 GbE 562T 2-port adapter is already installed and remains functional when a second processor is added.
