Detailed Specifications
Lenovo 7DH5A01UNA ThinkSystem ST250 V3 Tower Server
Overview
The Lenovo ThinkSystem ST250 V3 (7DH5A01UNA) is a high-performance, single-socket 4U tower server designed specifically for small-to-medium businesses (SMBs), edge computing, and remote office/branch office (ROBO) environments. Utilizing the Intel Xeon E-2400 processor series, it offers enterprise-class reliability and security in a compact form factor. This server is primarily deployed for file/print services, web serving, and business-critical applications in locations where a dedicated rack infrastructure may be unavailable.
Technically, the ST250 V3 introduces support for DDR5 memory and PCIe Gen5 connectivity, providing a substantial increase in data throughput and system responsiveness over previous generations. It is managed by the Lenovo XClarity Controller 2 (XCC2), which facilitates remote deployment, monitoring, and troubleshooting, reducing the need for on-site IT intervention. The server's acoustics are optimized for office environments, ensuring minimal disruption when placed in proximity to workstations.
Deployment is highly flexible; the unit can function as a standalone tower or be converted into a 4U rack-mounted system. It is ideal for infrastructure workloads and light virtualization but should not be utilized for high-performance computing (HPC) or large-scale AI training that requires multi-socket architectures or multiple high-wattage GPUs.
Key Features
