Abstract
Clustered storage systems and methods are presented herein. One clustered storage system includes a logical volume comprising first and second pluralities of storage devices. The first plurality of storage devices is different from the second plurality of storage devices and includes at least the same data as the second plurality of devices. The storage system also includes a first storage node operable to process first I/O requests to the first plurality of storage devices and a second storage node communicatively coupled to the first storage node and operable to process second I/O requests to the second plurality of storage devices. An I/O request of the first I/O requests initiates a redirection condition that the first storage node detects. Then, based on the redirection condition, the first storage node directs the second storage node to process data of the I/O request.
