Various systems and methods for determining and/or using paths through switches of distributed computing system. For example, one method involves accessing switch information by accessing switches using a first network protocol, where the switch information includes parameters of the switches. One or more nodes are configured to access storage devices using the switches, and the node is configured to perform the access using a second network protocol. The method also involves determining one or more paths through the switches, where path is configured to couple the node to the storage devices. The method also involves calculating a path score for at least one path, where the path score can indicate health of the path.
