Other features include full compliance with IEEE standards and FC-AL specifications for interoperability among vendors and easy integration with existing network infrastructure.
Fairness, especially when a shared bandwidth protocol like FC-AL is converted to switching, must be fully understood to appreciate the performance and system level ramifications of accessing large numbers of drives by a small number of controllers.
With more than 70 companies--including industry-leading disk drive, disk array, server, and networking connectivity suppliers--supporting FC-AL, it has become the most widely endorsed open standard for the SAN environment.
Adding InSpeed (basically interconnecting every FC-AL disk tray to a Vixel "chip-switch"), arrays become a switched bunch of disks (Vixel here introduces yet another acronym: SBODs), yielding a three- to five-fold speed improvement.
A pair of modern controllers have enough combined data bus and data memory bandwidth to transfer data between six 2Gbps back-end FC-AL buses and six 2Gbps front-end Fibre Channel fabrics at full speed, which removes internal bandwidth as a performance bottleneck.
FC-AL (Fibre Channel-Arbitrated Loop) configurations incorporate redundancy and switched FC fabric provides redundancy, alternate path routing, and zoning.
While all of the servers, hubs, and storage subsystems are based on the widely supported Fibre Channel protocol known as FC-AL, the early switch products are based on a newer protocol called "Fabric" and are positioned more for SAN backbone applications and less for storage consolidation applications.
Fibre Channel has become the industry standard interconnect with addresses for 127 devices on a single FC-AL loop and sixteen million on a fabric with cascaded switches.
