Dell PowerEdge R640 2x Xeon Gold 6148 256GB DDR4 10x 2.5

Dell PowerEdge R640 40-Core Rack Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage, backups and application hosting. Two Intel Xeon Gold 6148 processors deliver 40 cores total at 2.40 GHz, supported by 256 GB of DDR4 memory installed across the system. Ten 2.5-inch drive bays provide storage flexibility with eight bays capable of NVMe drives. The unit weighs 60 units and uses an LGA3647 socket platform.

Suited for virtualization hosts

This configuration suits IT teams deploying virtual machine clusters, database servers or mixed business applications that benefit from high core counts and large memory capacity. The NVMe-capable bays support low-latency storage tiers for performance-sensitive workloads. Buyers who need GPU acceleration for compute or rendering tasks should look elsewhere because only integrated graphics are present. Organisations requiring pre-installed operating systems or drives must provision those separately.

Ten 2.5-inch bays with eight NVMe-capable slots

The single specification that decides fit is the storage bay layout: ten 2.5-inch trays with eight wired for NVMe protocol. This determines which drive types can be used and the maximum NVMe device count without additional hardware. Maximum memory capacity reaches 3 TB across the platform, but the installed 256 GB DDR4 sets the starting point. No drives or operating system ship with the server.
