SYSTEMS AND METHODS FOR AVOIDING HOST LEVEL BUSY AND RETRY LATENCIES

In one embodiment, a system includes logic adapted for receiving a command from a first system, logic adapted for determining which resources are required to process the command, logic adapted for checking for the required resources before receiving data associated with the command, logic adapted for receiving the data from the first system, logic adapted for checking for the required resources after receiving the data when the checking for the required resources before receiving data indicated that the required resources were not available before receiving the data, logic adapted for sending a status to the first system if the required resources are not available after receiving the data, and logic adapted for processing the command if the required resources are available either before receiving the data or after receiving the data. In more embodiments, a method and computer program product for processing a command are also presented.
