Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack server configured with four 3.5-inch drive bays, one Xeon Silver 4214R processor at 2.4 GHz with 12 cores, and 256 GB of DDR4 ECC registered memory. A PERC H740P RAID controller and dual 750 W power supplies are installed, and remote management is provided by iDRAC9 Enterprise. No drives are included.

Who this suits and who should look elsewhere

This server suits buyers who need a dense 1U platform with four large-form-factor bays, a single 12-core Xeon, and 256 GB of DDR4 for virtualization or storage workloads. Buyers who want more storage bays, a second processor from the start, or a different memory capacity should look at other configurations.

The specification that decides fit

The chassis provides exactly four 3.5-inch SATA drive bays and supports a maximum of 7.68 TB of DDR4 across 24 slots, so the bay count and memory ceiling are the key constraints for any deployment.
