High-Density Performance in a Compact 1U Chassis
The Dell PowerEdge R640 delivers exceptional enterprise performance within a compact, standard-depth 1U chassis, making it ideal for data centres where space efficiency is crucial. Equipped with dual Intel Xeon Scalable processors and supporting up to 3TB of DDR4 ECC memory across 24 DIMM slots, the R640 provides robust computing capability to handle demanding workloads effortlessly. Versatile storage configurations—including support for up to 10 x 2.5” or 4 x 3.5” hot-swap drives, plus optional NVMe support—enable tailored setups that maximise both storage density and data throughput.
Optimised for Virtualisation, HPC, and Scale-Out Environments
Engineered for agility and flexibility, the R640 is perfectly suited for virtualisation platforms such as VMware ESXi, Microsoft Hyper-V, and Red Hat KVM, as well as for high-performance computing (HPC), edge deployments, and database management. Its powerful combination of high-core processors, extensive memory capacity, and advanced RAID controllers (including PERC H730P, H740P, and H750) make it ideal for intensive applications requiring rapid data access and reliable redundancy. Additionally, integrated Dell iDRAC9 with Lifecycle Controller ensures simplified remote management, rapid deployment, and streamlined maintenance operations.
