This article contains a list of which Xsan versions are compatible with which versions of Mac OS X client and server; the matrix shows required versions of Xsan and Mac OS X for when you want to upgrade your Xsan version.
Note: Xsan and Mac OS X versions running on MDCs must always be the same or later versions than those which are running on the Xsan clients (for example, clients running Xsan 2.2.1 on Mac OS X 10.6.8 means MDCs must be running Xsan 2.2.1 or later, and Mac OS X 10.6.8 or later). For more information about compatibility between Xsan versions within a SAN, see this article.
