Abstract
A method for processing an incoming command destined for a target is provided, comprising: determining if the incoming command is a data command or a management command; forwarding the incoming command to a storage management component of the target when the incoming command is a management command; when the incoming command is a data command: determining if a disk command queue on the target is full; sending the incoming command to the disk command queue when the disk command queue is not full; when the disk command queue is full: starting a timer, the timer having a predetermined length; sending the incoming command to the disk command queue when the disk command queue becomes not full prior to the expiration of the timer; and sending a rejection of the incoming command to the host only if, upon expiration of the timer, if the disk command queue is still full.
