Fiber Channel SAN switches and fabric QLogic and Emulex
Fibre channel is the storage connection of the past present and future.
Often overlooked, infrastructure have been using iSCSI instead of fibre channel, why because it is easier to install, configure and maintain (maybe). iSCSI works well but it has it limits in performance and bottle necks are frequently observed.
Fibre Channel has always had its misconception of being expensive and complicated although in some cases this might be true the cost of fiber outweighs the performance you can get out of this technology for instance you can now benefit from envy me connections using a whole slew of protocols.
