This is a 3-year Lenovo Premier Support service plan with Next Business Day response, sold for the Lenovo ThinkSystem SR630 V4 rack server. Premier Support is Lenovo's enhanced enterprise-tier warranty upgrade over the server's standard base warranty: it adds a single point of contact for hardware and (limited) software issues, direct access to more senior support engineers, and a committed next-business-day on-site or parts response instead of a longer default turnaround. It's bought alongside (or shortly after) a qualifying SR630 V4 server purchase, not as a standalone product — there's nothing physical to ship, it's an entitlement registered against that server's serial number for three years from activation.
