DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6148 2.4GHz 40-Core 64GB DDR4 8x 1.2TB SAS H740P

1U Rack Server for Virtualization

The Dell EMC PowerEdge R640 is a 1U rack server designed for business workloads such as virtualization, databases, and application hosting. It ships with two Intel Xeon Gold 6148 processors providing 40 cores total at 2.40 GHz with Turbo Boost up to 3.70 GHz. The system includes 64GB of DDR4 ECC Registered memory across 24 available slots. Eight 1.2TB 10K SAS drives and an H740P RAID controller handle storage duties.

Check Rack Space and Power Before Ordering

Verify your rack has 1U of free height and can supply redundant hot-swap power to the unit. The LGA 3647 socket configuration supports a maximum of two processors, which are already installed. Ensure your network infrastructure can use the quad-port 1GbE RJ45 controller for connectivity. The 24 DDR4 slots allow future memory expansion up to 3TB if workloads demand it.

Thermals Noise and Power in Normal Use

The 1U chassis uses internal fans to cool the dual 20-core processors and eight SAS drives under typical virtualization loads. Redundant hot-swap power supplies help maintain uptime during a module failure. Acoustic output is characteristic of a dense 1U rack server running sustained compute and storage tasks. Power draw scales with CPU utilisation and drive activity across the two 6148 processors.
