Flexibility is a measure of how rapidly you are able to deploy, shift, and redeploy new storage and host assets in a dynamic fashion without interrupting your currently running environment. An example of flexibility is your ability to simply connect new storage into the fabric and then zone it to any host in the fabric. You can do this without any interruption in the I/O to any of the other hosts in your environment. Flexibility can also be seen in the ability of the Fibre Channel directors to perform code loads, component replacement, and insertion while the system is running without any noticeable impact to the hosts.
