DELL PowerEdge R640 1U 10-bay 2.5" 2x Xeon Silver 4108 1.80GHz 16-core 128GB DDR4 H740P

1U 10-bay server for virtualisation and databases

The Dell PowerEdge R640 fits into a single rack unit and offers ten 2.5-inch drive bays for flexible storage configuration. Two Xeon Silver 4108 processors deliver sixteen cores at 1.80 GHz, while 128 GB of DDR4 memory supports multiple virtual machines and data-heavy applications. The H740P RAID controller simplifies storage management from day one. Drives are not included so you can select capacity and media type to match the workload.

Thermals noise and power in normal operation

The 1U chassis uses redundant cooling designed for continuous rack operation at typical utilisation levels. Power draw scales with the dual-socket CPU load and the number of installed drives rather than peaking at a fixed maximum. Fan speed adjusts automatically to maintain safe inlet temperatures without unnecessary acoustic output. The H740P controller operates within the same thermal envelope as the system board.

Behaviour under sustained load

During extended virtualisation or database sessions the dual Xeon configuration maintains consistent throughput across all sixteen cores. Memory bandwidth from the 128 GB DDR4 pool remains stable as working sets grow beyond burst capacity. The RAID controller sustains write performance through its onboard cache without throttling. Thermal headroom in the 1U form factor allows the system to run at full load for prolonged periods.
