The much-anticipated Xsan 1.1 updates are finally available for download. While each of the three above are obtainable via Software Update, you might prefer to check out these standalone installers. The release brings Tiger compatibility, new documentations, and a number of performance improvements, but
no few new features. The updates are free, and your existing Xsan serial numbers will of course continue to work. Don't forget to return to our forums to discuss your update experiences.
From the release notes:
If any system in your SAN is running Xsan 1.1 on Mac OS X v10.4, then your metadata controllers must also run the same. You can't use a metadata controller running on Mac OS X v10.3 if any client is running Xsan 1.1 on Mac OS X v10.4.
We read this to mean the following: If all your systems are running OS 10.3, a mix of Xsan 1.0.1 and 1.1 is O.K. But if any client has OS 10.4 and Xsan 1.1, then you must upgrade your metadata controllers to OS 10.4 and Xsan 1.1.
