Each of a plurality of descriptors having a completion indicator and being stored in a cache memory of an input/output processor

A method for input/output processing, comprising:

• creating a first descriptor by a host, wherein the first descriptor includes information associated with a first input/output request and a first completion indicator;
• linking the first descriptor to a preexisting second descriptor, wherein the second descriptor includes information associated with a second input/output request and a second completion indicator and wherein the first descriptor and the second descriptor are stored in a cache memory of an input/output processor;
• placing a first memory address associated with the first descriptor in a first address holder;
• processing a second memory address located in a second address holder and associated with a second data descriptor;
• processing the second input/output request;
• activating the second completion indicator;
• and
• removing the second descriptor by said host.

A method for input/output processing, comprising:

• creating, by a host, a first descriptor having a first completion indicator, wherein the first descriptor is associated with a first input/output process;
• linking the first descriptor to a preexisting second descriptor having a second completion indicator, wherein the second descriptor is associated with a second input/output process and wherein the first descriptor and the second descriptor are stored in a cache memory of an input/output processor;
• interfacing, by said host, with a completion indicator of the second descriptor;
• determining whether the second completion indicator indicates whether the second input/output process is complete.
