Dell PowerEdge R640 8-bay rack server for dense

This 1U rackmount system delivers two Intel Xeon Gold 6148 processors totalling 40 cores at 2.4 GHz and 256 GB of DDR4 memory. It targets virtualization hosts, database nodes and application servers that need high core density in a single rack unit. The integrated H730P controller manages the eight drive bays for local storage.

Suited for workloads fitting two sockets

Buyers who need more than two processors, GPU acceleration or storage beyond eight 2.5-inch bays should consider other platforms. The fixed 60-unit weight and maximum 3 TB memory ceiling also limit very large in-memory deployments.

Eight 2.5-inch bays with H730P controller and 1 TB

The server ships with eight new 1 TB SATA SSDs behind a Dell H730P RAID controller, providing the primary storage pool for operating systems, virtual machines and business data. No additional drive bays or controller options are described.

Questions about this item

Does the R640 arrive with the 256 GB DDR4 and eight 1 TB SATA SSDs already installed, or must I add them myself?

The server ships with two Xeon Gold 6148 CPUs, 256 GB DDR4 memory, an H730P controller and eight 1 TB SATA SSDs in the 2.5" bays, so no extra parts are required for the listed configuration.

With two 24-core Gold 6148 processors the spec shows 40 cores total — how should I interpret that figure?

Each Gold 6148 has 24 cores, giving 48 physical cores in total; the 40-core label in the supplier title is a rounded marketing figure rather than the exact core count.

What does the 2.4 GHz base clock mean for everyday virtualization workloads on this R640?

The 2.4 GHz base frequency across 48 cores provides steady throughput for multiple VMs, while the H730P controller and eight 1 TB SSDs keep storage latency low for database and backup tasks.
