1. A method comprising:

  • reading an access list defining an allowed subset of a plurality of information systems on a network supporting IP packets;

    receiving a request to create a first session to a first information-handling system of the plurality of information handling system; and

    if the first information-handling system is in the allowed subset then performing the tasks of;

    creating the first session, the first session defining a route for SCSI commands and data between the first information-handling system and a fibre-channel attached device, andprocessing IP packets containing one or more SCSI commands and data for routing between the first information-handling system and a fibre-channel attached device, wherein processing the IP packets includes;

    receiving IP packets through an internet protocol (IP) port coupled to the network,extracting the SCSI command and data from one or more of the received packets,routing the extracted SCSI command and data to a fibre-channel interface,inserting the extracted SCSI command and data into a fibre-channel data structure, andpassing the fibre-channel data structure to a first one of a plurality of storage devices on a fibre channel network.
