This is a Microsoft SQL Server 2022 Client Access License (CAL) pack covering 5 named users — a software licensing product, not physical hardware, sold here through Lenovo's Data Center Group channel. A CAL grants named users the legal right to access an already-licensed SQL Server instance; it's required in addition to the SQL Server core/server license itself for any organisation running SQL Server under the server+CAL licensing model rather than per-core licensing. This 5-user pack suits a small team or department accessing a shared SQL Server database, and would typically be purchased alongside (or as an add-on to) an existing SQL Server 2022 installation rather than as a standalone product.
