CurrentServerstower

The ThinkSystem ST650 V2 is Lenovo's flagship 4U tower and rack-convertible enterprise server powered by 3rd Generation Intel Xeon Scalable processors (Ice Lake). Engineered for remote branch offices, healthcare imaging facilities, creative studios, and distributed retail operations requiring high compute density, it supports 32 DDR4-3200 memory slots, up to 9 PCIe 4.0 slots, up to 4 double-wide GPU accelerators, and massive storage capacity up to 32 SFF or 16 LFF drives. The chassis provides whisper-quiet acoustic baffles for office environments. When buying second-hand units, administrators should verify whether tower feet or rack rails are included, check XClarity licensing, and confirm that high-wattage power supplies and auxiliary GPU power harnesses are present.
