Lenovo ThinkSystem SR650
The ThinkSystem SR650 was Lenovo's core two-socket 2U rack server for 1st and 2nd Generation Intel Xeon Scalable processors. Widely deployed across corporate data centers for virtualization, enterprise applications, databases, and software-defined storage, it succeeded the legacy System x3650 M5. It introduced AnyBay backplane technology allowing mix-and-match configurations of SAS, SATA, and NVMe U.2 drives in the same drive bays. In the secondary market, the SR650 is one of the most traded servers; buyers should inspect XClarity Controller (XCC) Enterprise license status, check RAID controller battery or supercapacitor health, verify drive backplane cabling, and check heatsink suitability for higher-TDP CPUs.
