Instead of a single device, you get a combination of servers with high speed and low latency. SAN can also have fiber channel connections to consistently ensure the fastest possible speed, delivery, security, and overall performance. By using a fiber channel, data is rerouted around the TCP/IP packetization and reduces any latency concerns, resolving congestion issues with the network. SAN keeps data exchanges across servers continually running smoothly and quickly. Some configurations may also have a private separate ethernet network to keep those servers running even more smoothly and keep traffic away from the primary fiber channel network, resulting in an even greater overall performance. SAN is extraordinarily robust, agile, and extremely flexible and can handle the huge amounts of compute and data sharing needed in today's busy dynamic digital environment.
