Novell® Storage Services™ for NetWare® supports multipath I/O (MPIO), a fault-tolerant and high-availability storage solution. NSS enables you to dynamically manage multiple, redundant connection paths between a server and its external storage devices, according to priorities you set. A single path serves as the primary, active interconnect; the other paths serve as failover paths. In the event of a failure in the active interconnect, NSS automatically and dynamically recovers to another available failover path. This feature is only available if you have multiple interconnect paths in your server-to-storage configuration.
