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.

System for monitoring and controlling host selection for a multi-host capable PCI-E device

A method for determining throughput of a data passing between end points of a data communication system as a function of bit error rate, comprising: generating a mathematical model of the functional relationship between the throughput of data passing from a transmitting one of a pair of end points of a data communication system and a receiving one of the pair of end points and a bit error rate of data received at the receiving one of the pair of end points.
