Fibre Channel Systems
Fibre Channel systems are assembled from adapters, hubs, storage, and switches. Host bus adapters are installed into hosts like any other SCSI host bus adapter. Hubs link individual elements together to form a shared bandwidth loop. Disk systems integrate a loop into the back plane. A port bypass circuit provides the ability to hot swap Fibre Channel disks and Fibre Channel links to a hub. Fibre Channel switches provide scalable systems of almost any size.
