This is a bundled software license — Microsoft SQL Server 2025 Standard edition paired with Windows Server 2025 Datacenter as a ROK (Reseller Option Kit) license, licensed for 16 cores and covering multiple languages (Multilang). A ROK license is tied to being sold alongside specific server hardware (in this case, catalogued under Lenovo DCG) by an authorised reseller, rather than purchased as a standalone retail or volume license. SQL Server Standard gives core relational database functionality suited to small-to-mid-sized business applications (as opposed to Enterprise edition's higher scalability ceiling), while the bundled Datacenter-edition OS underneath provides unlimited Windows Server VM rights on the host. Aimed at organisations deploying a new Lenovo server specifically for database workloads.
