Dual 24-Core Xeon Gold 6148 Server

The Dell PowerEdge R640 is a 1U rackmount server fitted with two Intel Xeon Gold 6148 processors. Each CPU runs at 2.40GHz and provides 24 cores, giving 40 cores in total. It is built for businesses that run virtualization, databases, file storage, backups or application hosting. Integrated graphics handle basic display output.

Ten 2.5-Inch Bays with NVMe Capability

The chassis holds ten 2.5-inch drive bays, eight of which support NVMe devices. The included H730P storage controller manages the ten new 1TB SATA SSDs installed from the factory. This layout caps internal storage expansion at the physical bay count; adding more drives requires external enclosures or a different chassis.

384GB DDR4 with 3TB Maximum

The system ships with 384GB of DDR4 memory installed and supports up to 3TB across its slots. Buyers whose workloads need more than 384GB today must plan for additional DDR4 modules, while those whose datasets exceed 3TB of active memory will need a platform with a higher ceiling.

Questions about this item

Should I pick the 40-core configuration or a lower core-count version for heavy virtualization?

The 40-core total from two Xeon Gold 6148 CPUs at 2.40GHz gives 24 cores per processor, which suits dense virtualization and multi-threaded workloads.

What does the 384GB DDR4 figure mean for actual VM density?

384GB DDR4 installed lets you run many virtual machines or memory-heavy databases simultaneously, with headroom to expand up to the platform maximum.

How do the 10 SATA SSDs and H730P controller limit real-world throughput?

Ten 1TB SATA SSDs on the H730P controller deliver capacity for OS, apps and backups, while the 2.5-inch bays also accept NVMe drives for faster tiers.
