Dell PowerEdge R640 40-Core Rack Server

The Dell PowerEdge R640 is a 1U rackmount server equipped with two Intel Xeon Gold 6148 processors running at 2.40GHz. Together they provide 40 cores and 128GB of DDR4 memory for demanding business workloads. Eight 1.2TB 10K SAS drives and an H730P controller deliver high-throughput storage. The system ships without an operating system.

Suits virtualization, database and backup workloads

This configuration supports multiple virtual machines, file storage and application hosting with its dual-processor design and large memory capacity. The eight-bay 2.5-inch chassis allows dense SAS storage expansion. Buyers who require GPU acceleration should look elsewhere. Organisations needing more than 3TB of memory or more than two processors must choose a different platform.

Dual Xeon Gold 6148 20-core processors

The two installed CPUs each have 20 cores at 2.40GHz on the LGA3647 socket, giving 40 cores total. This core count and clock speed determine throughput for virtualization and data-heavy applications. The board supports a maximum of two processors, so compute scaling stops at this configuration. Memory uses DDR4 technology up to 3TB across the available slots.

Preguntas sobre este artículo

How do I install the 2.5-inch SAS drives into the 8-bay front chassis and which step is often missed?

Slide each 1.2TB drive into a bay until the carrier clicks, then use the H730P controller BIOS to create a virtual disk before installing an operating system — skipping the array creation is the common oversight.

Which components will need replacement first during long-term operation?

The eight 10K SAS hard drives and the system fans are the primary wear items; DDR4 memory and the two Xeon Gold 6148 processors have no scheduled replacement interval.

What thermal or power limit appears first when the 40 cores run at 2.40GHz continuously?

The 1U chassis airflow ceiling is reached before the CPUs hit their maximum turbo, so sustained all-core loads will throttle to stay within the cooling envelope.
