A distributed instance system manages instances and communications between the instances. According to one embodiment, multiple parallel links between a central processing unit and a peripheral device are combined into a single channel, and cells on the various links are received in a round-robin order, and variations in flight time between the various links are compensated through a timer at each receive port of the bundle. Responsive to detecting a match between the current disk sequence and the previous disk IO sequence, a copy of data blocks accessed during the current disk sequence may be stored in a contiguous portion of the disk.
