Built for virtualization and databases

The Dell PowerEdge R640 delivers 40 cores from two Xeon Gold 6138 processors running at 2.00GHz. Sixteen gigabytes of DDR4 memory supports multiple virtual machines and data-heavy applications. Ten 2.5-inch bays with eight NVMe-capable slots let you choose the storage mix that fits your workload.

Installation notes and common issues

The H730 storage controller simplifies initial setup and ongoing drive management. Drives are not included, so you must source compatible 2.5-inch units before deployment. The chassis weighs 55 units and fits standard racks, but verify rail clearance and power-circuit capacity before mounting.

Sustained-load behaviour

Dual Xeon Gold 6138 CPUs maintain steady throughput for virtualization, databases and backup tasks over long periods. Memory can scale to 3TB when workloads grow beyond the factory 16GB. Integrated graphics and X540/I350 networking handle baseline display and connectivity without adding expansion cards.

Questions about this item

How can I verify the server is running correctly after installation?

Check the front-panel LEDs for power, Ethernet link and USB activity, and confirm the BIOS reports two Xeon Gold 6138 processors at 2.00 GHz with 16 GB DDR4 memory.

What components are included and which must be purchased separately?

The chassis, dual Gold 6138 CPUs, 16 GB DDR4 RAM, H730 controller, X540/I350 network ports and ten 2.5" bays are supplied; storage drives and an operating system are not included.

Which memory capacity should I choose for virtualization workloads?

Start with the installed 16 GB DDR4 for light testing, then add DDR4 modules up to the 3 TB maximum to match the number of virtual machines and dataset size you plan to run.
