Lenovo ThinkSystem SE450
The ThinkSystem SE450 is Lenovo's compact 2U single-socket ruggedized edge AI server engineered for complex artificial intelligence inference, computer vision, video analytics, and 5G open-RAN workloads deployed directly at telecom cell sites, retail centers, and industrial shop floors. Featuring an ultra-shallow depth of just 300 mm (11.8 inches) and front-accessible I/O and cabling, it fits comfortably into standard telco racks, wall enclosures, and outdoor cabinets. It pairs a 3rd Gen Intel Xeon Scalable processor up to 36 cores with support for up to 4 single-wide or 2 double-wide full-power GPUs (like the NVIDIA A100 or A30). When purchasing refurbished or used units, ensure tamper detection sensors have been unlocked in ThinkShield, check auxiliary GPU power cables, and verify whether AC or DC power supplies are installed.
