A method, system, apparatus, and signal-bearing media for provided discovering a target device via one port of a plurality of virtual ports, creating a target data structure associated with the target device, and allocating a second port of the plurality of virtual ports to a host if the second port is available. In an embodiment, an initiator identifier for the host may be created based on a port number of the second port and a media access control address and sent to the target device to identify the host.

Transparent mode

A method, system, apparatus, and signal-bearing media for finding a logical unit data structure associated with a command and a logical unit of a device, selecting a command table based on the logical unit data structure and a host that issued the command, indexing the command into the command table, and performing a routine indicated by the command table in response to the indexing. The command table may be a normal command table if no other host has reserved the logical unit or a reserved command table if another host has reserved the logical unit.

Reserve release proxy

A method, system, and logic for determining connectivity information for routers running on servers that are attached to a device. A router is resigned in favor of a corresponding router at another server when the corresponding router has better connectivity to the device, where partial connectivity is better than no connectivity, and full connectivity is better than partial connectivity.

Network router failover mechanism

A storage router having an internet protocol (IP) port for coupling to a network supporting IP packets, a fibre channel port for coupling to a fibre channel network to a plurality of storage devices, and a SCSI router having an iSCSI interface that extracts SCSI command and data information from packets received through the IP port, wherein the SCSI router passes the extracted SCSI command and data information to the fiber channel port. Some embodiments further include a session to an information-handling system. The session supports a target-only mapping (wherein a source-specified target value is replaced by a mapped target value that is then passed by the SCSI router toward a first storage device and its LUNs), or target-and-LUN mapping (wherein source-specified target and LUN information is replaced by mapped target-and LUN information such as a loop-ID and LUN combination, a WWPN and LUN combination, or a WWNN).

Session-based target/LUN mapping for a storage area network and associated method

A system and method for accessing Storage Area Networks over an IP network. A SCSI request is generated and encapsulated in one or more IP packets. The encapsulated SCSI request is routed over an IP network and received by a storage router. The storage router extracts the SCSI request from the one or more IP packets and routes the extracted SCSI request through a virtual SCSI router to the storage area network.

SCSI-based storage area network having a SCSI router that routes traffic between SCSI and IP networks

Virtual SCSI bus for SCSI-based storage area network

A system includes a configuration module operable to configure a routing device to communicate with one or more network devices. Each of the network devices having device identifiers and other device data. The device data can be maintained in a database. The system also includes a command interpreter for the configuration module. The command interpreter operates to display at least a subset of the device identification data in response to detecting a completion token entered by the user.

System and method for configuring fibre-channel devices

A method, system, apparatus, and signal-bearing media for determining connectivity information for routers running on servers that are attached to a device. A router is resigned in favor of a corresponding router at another server when the corresponding router has better connectivity to the device, where partial connectivity is better than no connectivity, and full connectivity is better than partial connectivity.
