DELL PowerEdge R640 1U rack server Dual Xeon Bronze 3106 384GB DDR4 H730 8x 2.5

Purpose-built virtualization server

The Dell PowerEdge R640 is a 1U rack server designed for business workloads such as file storage, virtualization, databases and application hosting. Dual Intel Xeon Bronze 3106 processors deliver 32 virtual threads at 1.7GHz to run multiple services simultaneously. With 384GB of DDR4 memory installed across 24 DIMM slots, the system supports dense virtual machine deployments and data-heavy applications. It targets IT teams that need a compact, redundant platform for core infrastructure tasks.

Chassis, power and connectivity

A 1U rackmount chassis houses redundant 750W hot-swap power supplies for continuous uptime. Eight 2.5-inch hot-plug drive bays accept SAS or SATA drives, while the integrated H730 controller manages RAID 0, 1, 5, 6, 10, 50 and 60 arrays. Networking starts with a four-port 1GbE daughter card, with optional 10GbE upgrades available. Three PCIe Gen3 x16 slots provide room for additional controllers or accelerators, and iDRAC9 with Lifecycle Controller enables remote firmware updates and hardware monitoring.

Memory ceiling decides fit

The installed 384GB matches the listed maximum memory capacity, leaving no headroom for future expansion without replacing modules. Buyers who anticipate growth beyond this limit or who require persistent memory options should evaluate a different configuration. The 24 DIMM slots are fully populated to reach this total, so any upgrade path requires module replacement rather than simple addition.
