A storage area network file system (SAN File System) is a scalable, SAN-based and highly available file system and storage management solution. It is used to aggregate files and share concurrent data in a multiplatform and open environment. It uses SAN technology, which helps enterprises connect and share multiple heterogeneous computers and storage devices across a high performance network.
A SAN File System is designed on a fiber channel (FC) network and built to offer exceptional input/output (I/O) performance for data sharing between heterogeneous computers. It also offers growth capability and simplified storage administration.
A SAN file system provides a universal namespace to a customer, enabling data production and distribution with the help of uniform file names from any application or client.
Integrity and data consistency are maintained through a SAN file system's control over distributed locks and lease utilization. A SAN file system provides locks that allow client file access and sharing, as required. To ensure these locks, the maximum time frame required by a metadata server is computed in a lease. To retain the locks, a client must contact the metadata server prior to the lease expiration date. A SAN file system also implements rules and policies for automated file allocation.
Key SAN file system attributes include:
