Abstract
A network of data processors for providing access to a resource, such as implemented a Storage Area Network that uses iSCSI and Microsoft MPIO-based network communication protocols. In preferred embodiments, the system or method uses (a) target-side consideration of MPIO disk structures, such as by having iSCSI initiators in from iSCSI targets via an iSCSI session object that is settable by a service action; and/or (b) uploading of routing tables from iSCSI targets to iSCSI initiator(s), such as to a Device Specific Module (DSM). Implementations may also involve, in a preferred embodiment: (1) requesting that the contents of the routing table be provided from the iSCSI target side storage servers to the iSCSI initiators, and using this as one of the factors influencing path selection as performed in the MPIO DSM on the initiator side; and/or (2) transmitting information from the iSCSI initiator to the iSCSI target storage server identifying connections as belonging to the same MPIO disk, and then receiving back from the iSCSI target storage server, information about the connections that should be created, and further then having a connection load balancer on the storage server hand…
