Mac OS X 10.7.1 is available on a USB drive for $69.

There are three ways to update to Lion Server v10.7.1:

Software Update installation

Choose Software Update from the Apple menu. When Software Updates states "Your software is up to date," you can be sure that all available updates have been installed.

Standalone installer

If you want to download and manually install the update, an installer is available from Apple Support Downloads. This is a useful option if you need to update multiple computers but only want to download the update once.

Remote installation

If you need to install the update on a remote server, you can do so using the Server Admin application or the software update command-line tool.
