English to Russian Tech/Engineering IT (Information Technology) Microsoft SQL Server

You can generate GUIDs not just in SQL Server using the NEWID function, but anywhere, using APIs. Otherwise, you could come up with a custom solution that generates smaller random keys. The solution can even be a mix of a built-in tool and some tweaking on top. For example, you can find a creative solution where the author uses the SQL Server sequence object, but flips the bits of the values so that the insertion is distributed across the index leaf.
