According to Jim Dalrymple (macworld.com), one of the goals for Xsan 2 was to make it easier for customers to set up a storage area network (SAN). “One of the ways Apple has accomplished this is with the SAN Setup Assistant, which is integrated into Mac OS X Leopard Server or as an application that can be run on its own.” “The setup assistant, Dalryple explains, does ”all the heavy lifting for you, setting up everything including Open Directory permissions.”
