Lenovo ThinkSystem SR650 V3
The ThinkSystem SR650 V3 is Lenovo's flagship two-socket 2U enterprise server designed for 4th and 5th Generation Intel Xeon Scalable processors (Sapphire Rapids and Emerald Rapids). Delivering PCIe Gen5 throughput, high-speed DDR5 memory architecture up to 5600MHz, and support for high-TDP accelerators up to 350W, it serves as the core platform for enterprise virtualization, AI model inference, in-memory databases, and high-density storage workloads. The server supports EDSFF E1.S and E3.S form factor drives alongside traditional SFF and LFF bays. Buyers in the second-hand market should confirm XCC2 Platinum or Enterprise license keys, check heatsink ratings (standard vs high-performance EVAC heatsinks), and verify the PSU wattage matches CPU and accelerator requirements.
