Dual Xeon Gold 6148 40-Core Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases and application hosting. Two Intel Xeon Gold 6148 processors provide 40 cores running at 2.40GHz for multi-threaded performance. 256GB of DDR4 memory supports multiple virtual machines and data-intensive services. The chassis offers ten 2.5-inch drive bays for flexible storage configuration.

Sustained Load Behaviour

The integrated H730P storage controller manages I/O across the ten drive bays to maintain consistent throughput during extended virtualization or database tasks. Dual-socket architecture distributes threads across both CPUs to avoid single-socket bottlenecks under continuous demand. DDR4 memory capacity of 256GB reduces swap activity when many services run simultaneously. Integrated graphics offload basic display output without consuming a PCIe slot.

Maximum Memory Capacity 3TB

The platform supports up to 3TB of DDR4 when fully populated, defining the ceiling for memory-heavy workloads. Buyers who need more than 3TB of RAM must choose a different server architecture. The ten 2.5-inch bays limit internal drive count compared to larger chassis options. No operating system is included, so licensing and installation are separate tasks.

Preguntas sobre este artículo

How much power do the two Xeon Gold 6148 CPUs draw under sustained load?

Each Xeon Gold 6148 has a 20-core design running at 2.40GHz; the pair gives 40 cores total, so sustained heat output will be significant and requires adequate rack airflow.

Which drive caddies and storage drives must I supply to populate the 10 2.5-inch bays?

The server ships with 10 empty 2.5-inch trays and an H730P controller; you must provide compatible drives and any required caddies yourself.

Can I keep using my existing DDR4 memory modules to expand beyond the installed 256GB?

Yes, the system uses DDR4 and supports up to 3TB total capacity, so compatible DDR4 modules can be added to the open slots.
