DELL PowerEdge R640 4LFF Xeon Gold 6154 64GB DDR4 No Drive

Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 4LFF is a 1U rackmount server system built for compute-intensive workloads. It ships with a single Intel Xeon Gold 6154 processor running at 3GHz with 18 cores and 24.75 MB cache. The system includes 64GB of DDR4 ECC registered memory and a PERC H740P RAID controller. This configuration targets businesses that need dense processing power in a compact form factor.

Four 3.5-inch drive bays and dual 750W supplies

The chassis provides four 3.5-inch hot-plug drive bays connected through the SATA interface and the PERC H740P controller. Dual 750W power supplies deliver redundancy for continuous operation. Remote management is handled by iDRAC9 with an Enterprise licence, allowing out-of-band monitoring and firmware updates. Integrated graphics and a 10GbE two-port 562T adapter cover basic display and high-speed networking needs without additional cards.

Upgrade from smaller rack servers

Organisations moving from 1U systems with fewer cores or limited memory capacity will gain 18 cores and headroom to 7.68TB of DDR4 across two processor sockets. The jump is worth it when virtualisation density, database throughput or licensing-per-core costs demand maximum performance per rack unit. Buyers who need more than four drive bays or GPU-accelerated workloads should evaluate larger chassis or specialised GPU servers.
