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:
