Storage Area Network (SAN) provide the ability to connect many computers to many storage devices, enabling the computers to negotiate device ownership among themselves, to share data, and eliminate islands of siloed information. The one defining characteristic of a SAN is universal connectivity of storage devices and computers. All clients, servers and storage devices in a SAN are interconnected through a switch fabric, typically iSCSI (GigE) or Fiber-channel.
Key fundamental SAN features are availability, capacity and performance. The I/O performance of a SAN must grow and scale as the number of interconnected devices grows. High-availability can be achieved through clustering, to ensure redundancy, reliability and recover-ability. SAN system applications include clustering, data replication, direct data copy between devices, and management applications for SAN zoning, device discovery, allocation and subsystem configuration.
NIC teaming, multi-path I/O, single-root I/O virtualization are some of the methodologies employed in a high-availability SAN architecture. Backup, cloning, replication and snapshot data services are also a common set of features employed in most SAN server and storage architectures today.
With the advent of software-defined-storage technology, combined with virtualization techniques and distributed embedded file systems, a virtual SAN solution has become a very attractive, cost-effective and highly-scalable hyper-converged storage platform alternative to traditional legacy SAN architectures. Virtual SAN architectures reduce the complexity and increases performance, reliability and scalability at an attractive price.
