Dell PowerEdge R640 8-bay rack server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6154 processors running at 3.0GHz. Eighteen cores per processor deliver thirty-six cores in total. The system ships with 256GB of DDR4 memory and eight 1.2TB SAS hard drives managed by an H730P controller. A quad-port X550-T4 network adapter is also installed.

Suited to virtualization and database workloads

This configuration targets businesses running virtualization, databases, file storage or application hosting. The installed memory and eight drive bays support multiple virtual machines and data-heavy services. Buyers who need more than 3TB of RAM or additional drive bays should consider a different chassis. Workloads that require dedicated GPU acceleration are not supported by the integrated graphics.

Maximum memory capacity of 3TB

The platform supports up to 3TB of DDR4 memory across its DIMM slots. The current 256GB installation leaves headroom for growth in memory-intensive applications. Verifying the existing DIMM layout before ordering additional modules ensures the final configuration reaches the desired capacity.
