The Xsan is a file system from Apple that allows you to share files and volumes of up to 16 TB on a high-speed Fibre Channel network. Up to 64 systems of the SAN can simultaneously read and record the information on shared volumes. In addition, it offers the possibility of distribute data across numerous array devices Raid (which in the case of Apple are the XServe Raid) to get better performance. Thus, each client makes use of this data centralized as if you were directly connected to them, as if it were your computer's hard drive.
Xsan storage networks they also eliminate the bottlenecks of files on Ethernet networks, whose performance worsens with the time as the use of denser formats increases like HD. The Xserve, on the other hand, is an option of external storage that combines Ultra disk technology High-capacity ATA, with a standard Fibre Channel interface 2Gb to ensure reliable and incredibly reliable data access fast.
