Storage array network path analysis server for enhanced path selection in a host-based I/O multi-path system

摘要

Systems and methods are provided for selecting a path through which to send data in a host-based multi-path system. In one embodiment, a system includes a management server that determines a topology of the network and analyzes a plurality of paths for sending data through the network. The management server may also create a path quality index based on the topology and the analysis, the path quality index indicating a quality of individual paths within the plurality of paths. The system further includes a host that receives the path quality index from the management server and automatically selects, based on the path quality index, a path from the plurality of paths through which to send data.
