SAN implementation over Gigabit Ethernet
A Storage Area Network is virtualized storage.
A storage area network (SAN) is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage systems.
A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move between servers as they need it. The storage can be added to and removed without requiring the server to be rebooted. The services provided by the server continue to operate without interruption.
The primary purpose for implementing a SAN is to provide a large storage pool that multiple hosts could access. Common storage configurations involve direct attachment of storage to a host. This storage is only available for use by that host. If there were another host that needed storage, you would need to buy additional storage to install on that host.
