Method and apparatus for providing virtual ports with attached virtual devices in a storage area network

摘要

Systems particularly a virtualization switch or a storage device, which include virtual ports connected to virtual devices with virtual worldwide names and virtual LUNs. Because Fibre Channel environment hosts can track worldwide names from one port to another and allow continuity in that regard, the virtual worldwide names are provided with relevant virtual LUNs and connected these to virtual ports so that the virtual devices can be moved as desired to overcome failures or to allow load balancing.
