Xsan is Apple Inc.'s SAN or clustered file system for Mac OS X.
Xsan enables multiple Mac desktop and Xserve systems to access
shared block storage over a Fibre Channel network. With the Xsan
file system installed, these computers can read and write to the
same storage volume at the same time. Xsan is a complete SAN
solution which includes the metadata controller software, the
file system client software, and integrated setup, management and
monitoring tools.

Xsan has all the normal features to be expected in an enterprise
shared disk file system, which includes support for large files
and file systems, multiple mounted file systems, meta data
controller failover for fault tolerance, support for multiple
operating systems etc.
