The Lenovo ThinkSystem SR860 V2 has been withdrawn from marketing and is no longer sold as a current product. The server is documented in a Lenovo Product Guide primarily for pre-sales reference, solution design history, and support of existing installations. If you already have SR860 V2 systems in production, Lenovo continues to provide documentation, management tools (such as Lenovo XClarity), and service options under the standard 1- or 3-year warranty and any purchased service upgrades. For new projects, Lenovo recommends considering current ThinkSystem platforms with similar 4-socket or GPU-optimized capabilities.

The ThinkSystem SR860 V2 is designed for demanding, mission-critical and data-intensive workloads that benefit from high CPU core counts, large memory footprints, and GPU acceleration. Typical use cases include: - **In-memory databases and SAP HANA**: Supports up to 12 TB of system memory with DDR4 alone, or up to 18 TB total when combining 12 TB of Intel Optane Persistent Memory 200 Series with 6 TB of DDR4 in App Direct mode. This helps organizations reimagine large in-memory deployments such as SAP HANA. - **Transactional and analytical databases**: Third-generation Intel Xeon Scalable Gold and Platinum processors (up to 4 CPUs, 112 cores, 224 threads) and up to 48x 2.5-inch drives (including up to 24 NVMe) support high I/O throughput for OLTP and analytics. - **AI, deep learning, and advanced analytics**: Supports up to four double-wide GPUs such as NVIDIA Tesla V100S or up to eight single-wide GPUs such as NVIDIA T4, plus enhanced deep learning instructions (bfloat16, VNNI) in the CPUs. - **Virtualization and server consolidation**: High core counts, up to 48 DIMMs, and up to 14 PCIe 3.0 slots enable dense VM hosting and consolidation of multiple workloads onto a single 4U platform. - **General business and line-of-business applications**: The flexible design allows organizations to start with two processors and scale to four as needs grow, while expanding memory and storage over time. Case studies referenced in the guide show the SR860 V2 being used in healthcare, manufacturing, and SAP environments where near-real-time insights and high availability are important.
