Features and aspects hereof allocate a range of exchange identifier (X_ID) values used in issuing a plurality of physical I/O operations to a plurality of physical FC target devices that comprise the virtual FC target volume. The plurality of physical I/O operations are dependent upon one another for completion of the original request to the virtual FC target volume and allow substantially parallel operation of the plurality of physical FC target devices. A primary X_ID is selected from the range of allocated X_ID values for communications with the attached host system that generated the original request to the virtual FC target volume."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for managing asynchronous dependent I/O for a virtual fibre channel target","description":"Methods and apparatus for managing exchange IDs for multiple asynchronous dependent I/O operations generated for virtual Fibre Channel (FC) target volumes.
