40-Core Rack Server for Virtualization

The Dell PowerEdge R640 is a 1U rackmount server system equipped with two Intel Xeon Gold 6148 processors. Each CPU provides 20 cores at 2.40GHz, delivering 40 cores total for demanding compute tasks. It ships with 256GB of DDR4 memory installed and supports up to 3TB maximum capacity. The integrated H740P storage controller manages the eight 2.5-inch drive bays behind the included front bezel.

Virtualization and Database Workloads

This server suits IT teams running hypervisors, database clusters, or multi-tenant application hosting where core count and memory bandwidth matter. The dual-socket LGA3647 design and large DDR4 capacity handle concurrent virtual machines and data-intensive services. Buyers who need GPU acceleration, high-frequency single-thread performance, or pre-installed operating systems should evaluate other platforms.

Eight 2.5-Inch Drive Bays with H740P Controller

The chassis provides eight hot-plug 2.5-inch bays wired to the integrated H740P RAID controller, defining the storage topology you can build. No drives are included, so you select SSD or HDD media that match capacity and endurance requirements. This bay count and controller combination determines whether the R640 fits your planned array configuration.

Questions about this item

What drives will the eight 2.5-inch trays accept for future upgrades?

The eight 2.5-inch trays are empty so you can populate them with the drive type and capacity that suit your workload.

Which limit appears first when both Xeon Gold 6148 CPUs run at 2.40 GHz under sustained load?

The 256 GB DDR4 memory ceiling is reached before the 3 TB maximum, so memory capacity becomes the first bottleneck.

How much heat and fan noise should I expect from the 60-weight chassis running all day?

Dual 20-core Xeon Gold 6148 processors at 2.40 GHz generate significant heat, so the system fans will run at elevated speeds continuously.
