See full text

Various systems and methods for scheduling commands of a storage area network to minimize latency are disclosed. For example, one method involves receiving a command, where the command is received prior to this command being issued to one or more storage devices. The commands is configured to be issued to the one or more storage devices using one or more paths. The method also involves determining whether the command is a high impact (HI) command, where this determination is based, at least in part, on one or more criteria. In response to a determination that the command is an HI command, the method involves selecting a first path of the one or more paths as a primary HI path, where the selecting is based on one or more other criteria. The availability of the primary HI path to non-HI commands is determined based on one or more different criteria.
