A system with a plurality of devices compatible with the Fiber Channel Protocol, with at least one initiator/originator and one target/responder. The initiator/originator is provided with the capability to send both data and command frames to the target/responder to increase write performance. The target/responder allocates a portion of its Responder-Exchange-Identifiers for the write use of the initiator/originator, which manages the use of these identifiers.

System and method for increasing write performance in a fibre channel environment

A computer system with a plurality of devices compatible with the Fibre Channel Protocol, wherein at least two of which devices are initiators. The computer system is provided with the capability to control and manage multiple initiators configured in an Arbitrated Loop. This capability is realized by manipulating the contents in outstanding.sub.-- link.sub.-- services arrays associated with the initiators.

System and method for controlling multiple initiators in a fibre channel

A computer system with a plurality of devices compatible with the Fibre Channel Protocol, which computer system is provided with the capability to dynamically alter the configuration of the plurality of devices without a system reset, or without additional software overhead. This capability is realized by providing unique mapping relationships between low-level Fibre Channel information structures related to the devices and upper-level link elements compatible with an Operating System associated with the computer system.

System and method for automatically and dynamically changing an address

A computer system with a plurality of devices compatible with the Fibre Channel Protocol. The computer system is provided with the capability to recover from a loop hang condition resulting from an unresponsive communication link in an Arbitrated Loop. This capability is realized by providing a sense mechanism for detecting a no-change condition in the states associated with a controller arranged in the Arbitrated Loop.
