The Lenovo ThinkSystem SR645 is a 1U/2U AMD EPYC-based rack server, configured here with two AMD EPYC 7352 processors (24 cores each, second-generation EPYC/Rome) and four 32GB memory modules (128GB total). The dual-socket EPYC platform gives high core density and strong memory bandwidth per rack unit, a common choice for virtualization hosts, database servers and general enterprise compute where per-rack-unit performance and power efficiency matter. As a rack server it's intended for proper data centre or server-room deployment rather than an office desk, and is aimed at IT teams building out or refreshing server infrastructure needing solid multi-socket AMD performance.
