Patent number: 7443788Abstract: A method and apparatus for improving performance of a loop network, in particular a Fiber Channel Arbitrated Loop. The loop network has two loops and a plurality of dual-ported devices each with one port on each loop. The method includes selectively bypassing redundant ports on the loops by a first command means in the form of a Fiber Channel Arbitrated Loop command to balance port accesses and to reduce the loop overhead by reducing the number of ports in each loop. In the event of a fault, bypassing the port of a device by a second command means in the form of a non Fiber Channel Arbitrated Loop command and enabling all the bypassed redundant ports with a single command to all ports using the first command means. The first command means does not enable the port bypassed by the second command means.Type: GrantFiled: August 6, 2002Date of Patent: October 28, 2008Assignee: International Business Machines CorporationInventors: Paul Nicholas Cashman, Robert Frank Maddock, Robert Bruce Nicholson, Michael Alan Veal
