Layering communication fabric protocols

An apparatus for layering communication fabric protocols, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

• allocating storage resources on an initiating storage system for a data transfer, wherein a command protocol to implement the data transfer specifies an exchange of multiple messages;
• receiving, from a target storage system and into the allocated storage resources at the initiating storage system, data within a single message corresponding to the command protocol that specifies an exchange of multiple messages to implement the data transfer;
• and
• in response to receiving the data within the single message corresponding to the command protocol that specifies an exchange of multiple messages to implement the data transfer, generating a status message indicating receipt of the data.

A computer program product for layering communication fabric protocols, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

• allocating storage resources on an initiating storage system for a data transfer, wherein a command protocol to implement the data transfer specifies an exchange of multiple messages;
• receiving, from a target storage system and into the allocated storage resources at the initiating storage system, data within a single message corresponding to the command protocol that specifies an exchange of multiple messages to implement the data transfer;
• and
• in response to receiving the data within the single message corresponding to the command protocol that specifies an exchange of multiple messages to implement the data transfer, generating a status message indicating receipt of the data.
