Detailed Specifications
Lenovo 7D7A100MNA ThinkSystem ST650 V2
Overview
The Lenovo ThinkSystem ST650 V2 (7D7A100MNA) is a high-performance 4U tower server designed to bring enterprise-level data center compute power to office environments, remote branches, and edge locations. Built on 3rd Generation Intel Xeon Scalable processors, it provides the scalability required for intensive workloads such as database management, virtualization, and private cloud infrastructure without the need for a dedicated rack cabinet.
Technical capabilities include support for up to 32 DDR4 DIMM slots and PCIe Gen4 expansion, which doubles the I/O bandwidth over previous generations.This enables the server to support up to eight single-width or four double-width GPUs, making it a viable platform for AI inference and medical imaging at the edge.Management is handled through the Lenovo XClarity Controller (XCC), providing standardized hardware monitoring and remote deployment capabilities across the enterprise.
Deployment is versatile; while optimized as a standalone tower with quiet acoustic profiles for office use, it is also rack-convertible for standard 19-inch data center cabinets. It is highly compatible with software-defined storage (SDS) and hyperconverged infrastructure (HCI) solutions but should not be used in environments requiring ultra-short depth chassis due to its high-capacity storage design.
Key Features
Dual 3rd Gen Intel Xeon Scalable processors with up to 36 cores per socket.
32 DIMM slots supporting up to 4TB of TruDDR4 3200MHz system memory.
Nine PCIe Gen4 expansion slots for high-speed networking and GPU acceleration.
Integrated dual 10GBASE-T ports for high-bandwidth standard connectivity.
Front-loading hot-swap drive bays support SAS, SATA, and NVMe media.
