About the Lenovo ThinkEdge SE455 V3
The Lenovo ThinkEdge SE455 V3 is a purpose-built, short-depth edge server that packs a single AMD EPYC 8004 Series "Siena" processor - up to 64 cores across an 80W to 225W TDP envelope - into a rugged 2U chassis just 438mm deep. Designed for deployment outside the data centre, it meets NEBS Level 3 requirements, tolerates 5°C to 55°C operating temperatures, and can be fitted with a front dust filter and locking security bezel. Six TruDDR5 RDIMM slots deliver up to 768GB at 4800 MHz, while four front hot-swap 2.5in bays (plus an optional four internal) and dual M.2 boot drives cover SATA and NVMe storage.
With up to six single-wide or two double-wide GPUs (including NVIDIA L4 24GB on the inference model) and AMD Alveo V70 accelerator support, plus six PCIe slots and an OCP 3.0 slot for 1/10/25/100GbE, the SE455 V3 suits edge AI inferencing, telco vRAN Distributed Unit, retail and video-analytics workloads. Redundant front-serviced power (1100W Titanium/Platinum AC, 1800W Platinum AC or 1100W -48V DC) and XClarity Controller 2 management round out a true edge platform. Servnet configures, prices and supplies the ThinkEdge SE455 V3 in the UK, with every specification verified against the Lenovo Press product guide.
