About the Lenovo ThinkSystem SR860 V4
The Lenovo ThinkSystem SR860 V4 is a four-socket, 4U rack server built for the most memory-hungry enterprise workloads. It pairs two or four Intel Xeon 6700-series P-core processors - up to 86 cores each - with 64 DDR5 DIMM slots for as much as 16 TB of memory running at up to 6400 MHz, plus optional CXL 2.0 memory expansion. Advanced RAS features including SDDC, ADDDC and memory mirroring keep large in-memory datasets protected, making it a natural fit for in-memory databases, data lakes, big data analytics, business intelligence and OLTP, as well as SAP HANA deployments.
Storage and expansion scale to match: up to 48x 2.5-inch hot-swap drives or dense EDSFF E3.S NVMe configurations, up to 18 PCIe slots (16x Gen5 plus 2x Gen4) and two OCP 3.0 slots delivering up to 400GbE, alongside support for up to 8x single-wide or 4x double-wide GPUs. Up to four redundant 80 PLUS Platinum/Titanium power supplies (up to 3200W), 12 N+1 hot-swap fans with optional open-loop water cooling, XClarity Controller 3 management and TPM 2.0 with PFR round out a resilient platform. Servnet configures, prices and supplies the ThinkSystem SR860 V4 in the UK, with every specification here verified against the Lenovo Press product guide.
