    摘要: A Fiber Channel switch is provided for a relative addressing scheme for domain values to avoid losing portions of a Fiber Channel identifier. At a Fiber Channel switch, data is stored that assigns a relative domain field value to a run-time domain. The relative domain field value used for a Fiber Channel identifier is determined for devices connected to the switch based on the run-time domain of the devices and the virtual storage area network in which the devices are active. A Fiber Channel identifier is stored in a memory of the switch that comprises the relative domain field value determined for the device together with area and port values for the device. The relative domain value is either a reserved domain field value for an existing virtual storage area network or any of the regular domain field values for a new virtual storage area network.

    摘要: Certain embodiments of the present disclosure generally relate to allocating a sub-area of Fibre Channel addresses (FCIDs) to a device. A range of addresses may be assigned to the device using a mask address, where the most significant bits represent a mask and the least significant bits represent a sub-range of FCIDs available to be assigned to the device. Therefore, routing information may be stored efficiently in a Ternary Content Addressable Memory (TCAM) by storing a single entry in the TCAM for each sub-area of FCIDs allocated to a device, instead of storing an entry for each FCID. The single entry may indicate the mask address and the width of the mask.

    摘要: A Fibre Channel switch and related methods are provided for a relative addressing scheme for domain values used by the switch to avoid losing other portions of a Fibre Channel identifier if a particular run-time domain becomes invalid. At a Fibre Channel switch, data is stored that assigns a relative domain field value to a run-time domain in one of a plurality of virtual storage area networks. The relative domain field value used for a Fibre Channel identifier is determined for each of a plurality of devices connected to the Fibre Channel switch based on the run-time domain of the respective devices and the virtual storage area network in which the respective devices are active. A Fibre Channel identifier is stored in a memory of the Fibre Channel switch for each of the plurality of devices. The Fibre Channel identifier comprises the relative domain field value determined for the device together with area and port values for the device. The relative domain value is either a reserved domain field value for an existing virtual storage area network or any of the regular domain field values for a new virtual storage area network. The reserved domain field value is a domain field value that is not to be explicitly used in a Fibre Channel network for Fibre Channel identifiers according to the applicable Fibre Channel industry standards.

    摘要: The number of domain identifiers is incrementally increased for use by a switch in an established fiber channel switched fabric. In other words, the number of domains assigned to a switch by the Principal Switch of the fiber channel switched fabric is increased without triggering the reconfiguration of the established fiber channel switched fabric. In one implementation, incrementally adding one or more additional domain identifiers includes requesting said one or more additional domain identifiers from a Principal Switch of the fiber channel switched fabric using a different World Wide Name (WWN) than used to acquire the original one or more domain identifiers used by the switch.
