You now understand what advantages a storage area network SAN and storage networking technologies can do for your business network. Storage arrays were initially all hard disk drive systems, but are increasingly populated with flash solid-state drives SSDs.

Organizations use SANs for distributed applications that need fast local network performance. SANs improve the availability of applications through multiple data paths.
They can also improve application performance because they enable IT administrators to offload storage functions and segregate networks. Additionally, SANs help increase the effectiveness and use of storage because they enable administrators to consolidate resources and deliver tiered storage. SANs also improve data protection and security. Finally, SANs can span multiple sites, which helps companies with their business continuity strategies.
A SAN switch's only job is to move storage traffic. The switch checks the data packet and identifies its origin and destination. Then, the switch directs the packet to the right storage system.
FC switches are meant to be used with high-performance networks. SAN switches can also be Ethernet based.
Organizations can combine many switches to build large SAN fabrics that connect many servers and storage ports.
