Rare server software update
Apple has released Xsan 2.2.2, a rare update to its storage area network software. The patch is specifically labeled the FileSystem Update for 10.6, and fixes problems with filesystem reliability as well as "low-memory client behavior." It applies only to copies of Xsan running on Snow Leopard clients or servers. To go with it, Apple has posted a new Xsan Uninstaller.
