Leopard, Snow Leopard versions available
Beyond a Mail Services update, Apple is also targeting the enterprise this week with updates to Xsan, its storage area network software. The v2.2.1 FileSystem Update is said to include "general" filesystem fixes, as well as particular corrections for reliability and the cvfsck repair utility. Editions are available for both Leopard and Snow Leopard.
Apple has correspondingly released a v2.2.1 uninstaller, which completely removes Xsan including the Admin tool and any documentation files. Though the software requires Mac OS X 10.5, it can allegedly remove any version of Xsan at or beyond v1.4.2, on Mac OS X 10.4 or later. The file is a 545KB download.
