    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.

    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: In one embodiment, a technique for performing partial build fabric operations when merging two or more Fibre Channel fabrics is provided. By maintaining a Principal Switch already assigned for one of two merging fabrics, a limited “partial build” may be performed for the other merging fabric. As a result, the time required for a Principal Switch selection phase may be greatly reduced.
