Features

Accelerated Compute for AI and HPC
The ThinkSystem SR685a V3 is an 8U2S rack server built for demanding AI and HPC workloads. It’s accelerated for intense computing using industry-leading 4th Generation AMD EPYC™ Processors, interconnects with the fastest transfer rate with AMD’s Infinity Fabric or NVIDIA’s NVLink, and supports 8x of the latest GPUs. It has the computing power to tackle modeling, training, rendering, financial tech, scientific research, and more.

Choice and Flexibility
ThinkSystem SR685a V3’s open architecture design enables it to be configured to meet unique workload requirements by offering the flexibility of choice.
Whether you choose to operate AMD on AMD by selecting the MI300x or if you go with NVIDIA H100/H200, we have you covered. You can choose which is right based on workload needs and availability.

Premium User Experience
At Lenovo, we think beyond standards to offer a premium user experience with the ThinkSystem SR685a V3 by adding resilient power supplies, thermals for next-generation GPUs, and easy systems management.
This workhorse includes power supplies supporting full N+N redundancy without throttling, providing maximum resiliency.
Air-cooled with N+1 hot-swap fans; this machine provides sufficient thermal headroom to accommodate today’s and future higher-power GPUs.
The ThinkSystem SR685a V3 includes Lenovo XClarity systems software for ease of deployment and management.
