This is a Microsoft SQL Server 2022 Client Access License (CAL) covering 5 devices — a licensing product, not physical hardware or software media. A Device CAL licenses up to 5 specific machines (PCs, terminals, etc.) to connect to and use a properly-licensed SQL Server instance, which is typically the more cost-effective CAL model in environments with more users than devices (e.g. shift workers sharing terminals) rather than a per-user model. It's bought alongside an existing or new SQL Server 2022 server license to legally cover the client side of that deployment, and is sold through Lenovo's DCG (Data Center Group) reseller channel rather than directly from Microsoft.
