Storage requirements have been grown exponentially doubling every 18 months. The only way to solve this has been to buy servers with large attached disks and mapping the drives to make them accessible across the Ethernet network.
The growth of servers, RAM, CPU, power supplies, rack space, power consumptions, UPS capacity and heat output continues to increase the cost per megabyte of disk space.
Storage Area Network is a self contained system with built in redundancy ensure that this big rack of disks has no single point of failure and continues to keep data available for processing.
SAN's contain high speed medium cost for continuous use and slow speed, low costs disks for seldom used data such as archives or backups. Access to the data is by fiber optic interface cards for high speed and also by normal Ethernet connections when speed is not so critical.
Processing speed gains can be achieved by avoiding Ethernet network bottlenecks by using the fiber connections.
Storage scalability allows for growth and storage of new data types as the business grows.
Central storage allows virtualization of servers, which allows dynamic changes to be made to balance loads, recover from failures as schedule maintenance without downtime.
The Major benefit of SAN is maximizing availability of systems.
