Dell PowerEdge R640 8-bay 2.5-inch 48-core server

The Dell PowerEdge R640 is a 1U rackmount server system fitted with two Intel Xeon Platinum 8268 processors running at 2.90 GHz. Each processor contributes 22 cores, giving a total of 48 cores for compute-intensive workloads. It ships with 256 GB of DDR4 memory and eight 600 GB 10K SAS hard drives in the front bays. An integrated H730P storage controller manages the drive array.

Suited for virtualization, databases.

This configuration targets businesses running multiple virtual machines, database instances, or file-storage services that benefit from high core counts and fast SAS storage. Buyers who need more than 256 GB of memory or additional drive bays should consider other platforms. The integrated graphics and lack of discrete GPU support limit use for graphics-heavy workloads. The server arrives without an operating system installed.

Dual-socket LGA3647 supports exactly two Xeon

The motherboard provides two LGA3647 sockets and is populated with a matched pair of Platinum 8268 processors; no further CPU upgrades are possible beyond this maximum. Memory capacity can scale to 3 TB using DDR4 modules, but the installed 256 GB is the starting point. Storage expansion is confined to the eight 2.5-inch SAS bays served by the H730P controller.

Questions about this item

How many Xeon cores are active when both processors run at 2.9 GHz under sustained load?

The system ships with two Platinum 8268 CPUs, each providing 22 cores for a total of 48 cores at 2.9 GHz.

What cooling demand should I plan for when the eight 600 GB SAS drives and both CPUs run continuously?

Two 22-core Xeon CPUs and eight 10K SAS drives generate significant heat; ensure your rack provides adequate front-to-rear airflow.

Which memory type must already be installed to reach the 256 GB capacity shown?

The server uses DDR4 modules; the 256 GB configuration is populated with DDR4 DIMMs.
