2U/1P Optimized for VDI and SDS

World-Class Performance

The Lenovo ThinkSystem SR655 with the next generation AMD EPYC™ architecture delivers outstanding TCO for Virtualization, Big data, Analytics, and scale up software defined deployments. It offers two-socket performance in a 2U, single-socket design, featuring higher core, and storage density; increased I/O throughput with less latency; along with built-in system security.

The SR655 proves highly capable when managing both rising data center costs and data volumes while also addressing ever-expanding capability requirements for the software-defined data center.

With the enterprise class AMD EPYC™ 7002 Generation processor, the world’s first 7nm data center CPU, the SR655 features up to an unprecedented 64 cores with 128 PCIe lanes in a single socket to reduce bottlenecks and increase server utilization.

Compared to the previous processor generations, ThinkSystem servers with AMD architecture deliver up to 2X performance and 4X floating point capability, providing faster data transfer and analytics without sacrificing memory capacity or I/O with PCIe Gen4 support and faster memory speeds up to 3200MHz.

Flexible Design

ThinkSystem SR655 is a multi-GPU optimized rack server, providing support for up to 6 single-wide GPUs that offer 200% more workload acceleration in AI Inference, and virtualized desktop infrastructure (VDI).

Harnessing the power of 64 cores to VDI instances provides cutting edge application efficiency in health care applications such as EMR, PACS, and medical imaging or electronic trading platforms for financial services applications.

The SR655 can support up to 32 NVMe solid-state drives that, when paired with high speed networking, make it an excellent choice for workloads that need large amounts of low-latency high-bandwidth storage, including virtualized clustered SAN solutions, software-defined storage (SDS), and applications leveraging NVMe over Fabrics.

Outfitted with up to 9x PCIe Gen4 slots provides scalability that make it well-suited for capacity planning and supply chain optimization in the manufacturing industry, networking security, and telco use cases.
