Abstract
A storage system that includes multiple CPU hosts and PCI-E multi-host capable devices uses link selection controllers to map shared memory addresses to individual PCI-E links such that each address is accessed via only one of a plurality of PCI-E links. The addresses may be grouped into same-size segments, each of which contains only addresses mapped to the same PCI-E link. The link selection controllers monitor for state changes that affect PCI-E link availability and, in response to detection of a failure, coordinate a response that includes re-mapping the affected addresses.
