Xsan

Finding the right file can be like finding a needle in a haystack, especially when you have terabytes upon terabytes of shared online storage. Xsan 2 leverages the power of Spotlight, making it easy and instantaneous for users to find files on massive SAN volumes — even across terabytes of data — right from the Finder. 

Spotlight works the way people think: by searching the content itself, not just the filenames. With richer Spotlight vocabulary in Mac OS X, searches can be more exact. Options include Boolean logic, quoted phrase searching, category labels, and range support. And with the Quick Look and Cover Flow features in Mac OS X, users can scan hundreds of files in just seconds, without ever needing to open them.
