Abstract
A first image processing system, a second image processing system, a first storage system and a second storage system communicate over a high bandwidth switch. The switch connects the first processing system to the first storage system and also connects the second processing system to the second storage system. At the first image processing system, first location data is read to identify the location of frames on the first frame storage system. Similarly, at the second image processing system second location data is read to identify the location frames on the second frame storage system. In response to control commands issued to the switch, the first image processing system is disconnected from the first storage system and reconnected to the second storage system. Similarly, the second processing system is disconnected from the second storage system and reconnected to the first storage system. In response to the reconnection operations, the second location data is read at the first image processing system and the first location data is read at the second processing system. In this way, immediate and automatic access to the reconnected storage systems is achieved.
