摘要： A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.

摘要： A network switch allows defining a virtual port worldwide name (VPWWN) and associating the VPWWN with an F_port of the network switch, for use by a host bus adaptor (HBA) connecting to the network switch. Both a default and a user VPWWN may be defined, with the user VPWWN typically taking precedence over the default VPWWN. A database of VPWWN associations may be used to ensure uniqueness of the user VPWWN. Where the HBA allows dynamic assignment of WWNs, the VPWWN may be pushed to the HBA. The VPWWNs may be deleted, and moved to another port as desired.
摘要翻译： 网络交换机允许定义虚拟端口全球名称（VPWWN），并将VPWWN与网络交换机的F_port相关联，供连接到网络交换机的主机总线适配器（HBA）使用。 可以定义默认和用户VPWWN，用户VPWWN通常优先于默认VPWWN。 可以使用VPWWN关联的数据库来确保用户VPWWN的唯一性。 在HBA允许动态分配WWN的地方，VPWWN可能被推送到HBA。 VPWWN可能被删除，并根据需要移动到另一个端口。

摘要： Subsets of isolated communications networks are selectively merged without merging the entire isolated communications networks, and devices are imported across isolated communications networks without merging the isolated communications networks. The presently disclosed technology provides for improved scalability, performance, and security in logical networks spanning two or more physical communications networks.
