Target workloads

The Dell PowerEdge R640 is a 1U rack server built for virtualisation, database and general compute tasks. It ships with a single Intel Xeon Silver 4114 processor running at 2.2GHz with 10 cores and 128GB of DDR4 ECC registered memory. The chassis supports up to four 3.5-inch SATA drives and includes a PERC H740P RAID controller. A second processor socket is available for future expansion up to the platform maximum of 7.68TB memory.

Thermals and power

Dual 750W power supplies provide redundancy for continuous operation in a 1U form factor measuring 36 by 24 by 10 inches and weighing 40 units. The system uses integrated graphics, which keeps power draw lower than configurations with discrete accelerators. Firmware and BIOS are updated to the latest stable release before shipment, and each unit undergoes a full burn-in test to verify thermal stability under load.

Remote management and networking

The embedded iDRAC9 Enterprise licence enables out-of-band monitoring, remote console access and automated firmware updates without an operating system. A dual-port 10GbE 562T adapter delivers high-throughput networking for storage replication or cluster traffic. Rail kits are available on request to simplify rack installation. The server arrives without drives, allowing you to select capacity and endurance ratings that match your workload.

Questions about this item

How is the PERC H740P RAID controller installed in the PowerEdge R640, and what step is often missed?

The PERC H740P seats in a dedicated internal slot; the step often missed is connecting the controller to the four 3.5-inch drive bays using the correct internal cables.

What maintenance or replacement will the two 750W power supplies need later?

The two 750W units are hot-pluggable; replace a failed unit by sliding it out and inserting a new one without powering down the server.

What limit appears first when the Xeon Silver 4114 runs sustained workloads at 2.2GHz?

The 10-core processor will hit its thermal ceiling before the 128GB DDR4 memory or the dual 10GbE 562T network ports become bottlenecks.
