Dell PowerEdge R650 Rack Server — Product Overview & Specifications
Product Overview
The Dell PowerEdge R650 is a hyper-dense, dual-socket 1U rack server designed to optimize workload performance and data center density. Powered by up to two 3rd Generation Intel Xeon Scalable processors with up to 40 cores per socket, the R650 delivers exceptional performance for the most demanding workloads .
The system supports up to 32 DDR4 DIMM slots with speeds reaching 3200 MT/s, accommodating RDIMM, LRDIMM, NVDIMM, and Intel Optane Persistent Memory 200 series. Maximum memory capacity reaches 2 TB with RDIMM, 4 TB with LRDIMM, and up to 8 TB with Intel Persistent Memory .
Storage flexibility is achieved through support for up to 10 × 2.5-inch or 4 × 3.5-inch front drives, with additional rear drive options. The R650 supports PCIe Gen4 and up to 24 NVMe drives, delivering substantial throughput improvements for data-intensive applications .
With up to 3 PCIe Gen4 expansion slots, iDRAC9 management, and optional Direct Liquid Cooling, the R650 is ideal for mixed workload standardization, database and analytics, VDI, and AI/ML environments requiring performance and GPU support in a dense 1U form factor .
