Xsan Overview Xsan is a storage area network file system (ACFS, or Apple Cluster File System) and a management application (Xsan Admin) you can use to provide expandable storage to users or applications on client computers with shared high-speed access. [View full size image] The Network A storage area network (SAN) is a way of connecting computers to storage devices that gives users very fast access to files and gives administrators the ability to expand storage capacity as needed without interrupting users. An Xsan SAN consists of the following: • Volumes of shared storage, stored on Apple Xserve RAID (Redundant Array of Independent Disks) systems, available to clients as mounted volumes that they can use like local disks • At least one computer acting as a metadata controller that coordinates access to the shared volumes • Client computers that access storage in accordance with established permissions and quotas • Underlying Fibre Channel and Ethernet networks The following illustration shows the physical components of a typical Xsan SAN: [View full size image] SAN Volumes Shared SAN volumes that you create in the Xsan Admin application will appear to the client as a single local volume. You can create these volumes by selecting a combination of RAID arrays to be included in a pool, which, in turn, is added to create the volume. Volumes can be up to 1024 terabytes (TB) in size, which means a client machine will be able to display up to eight 1024 TB volumes on its desktop. Furthermore, clients can write one file that is 1024 TB in size, or create up to 4 billion files and directories per volume!
