    • A storage array presents virtual arrays to hosts through use of virtual port IDs. The storage array includes groups of logical units of storage. The groups are coupled to a switch through at least one physical port. Each group is assigned a unique virtual port ID for each physical port to which it is coupled. The virtual port IDs are assignable by the switch. The virtual port IDs are used by hosts coupled to the switch to exchange data with the groups to which the virtual port IDs are assigned. Further, a zoning table in the switch can associate each virtual port ID to a host facing port on the switch. In this case each host can communicate only with groups of logical units that are assigned virtual IDs associated with the host facing port to which it is coupled.
    • 存储阵列通过使用虚拟端口ID向主机呈现虚拟阵列。 存储阵列包括逻辑存储单元组。 这些组通过至少一个物理端口耦合到交换机。 为每个组分配与其耦合的每个物理端口唯一的虚拟端口ID。 虚拟端口ID可由交换机分配。 虚拟端口ID由耦合到交换机的主机用于与分配了虚拟端口ID的组交换数据。 此外,交换机中的分区表可以将每个虚拟端口ID与交换机上面向主机的端口相关联。 在这种情况下,每个主机只能与被分配与其所耦合的面向主机的端口相关联的虚拟ID的逻辑单元组通信。

    • Failover is provided between groups of logical units of storage presented as virtual arrays. A primary virtual array has at least one primary virtual port coupled to a fabric, each primary virtual port having a source virtual port name and a source virtual port address. A secondary virtual array has one or more secondary virtual ports coupled to the fabric, each secondary virtual port having a secondary virtual port name and a virtual port address. All data resident on the primary virtual array is copied to the secondary virtual array. If a failure occurs in the primary virtual array, the secondary virtual port names and LUN names and numbers are replaced with the primary virtual port names and LUN names and numbers. The fabric updates its name server database so that the database associates the primary virtual port names and LUN names and numbers with the secondary virtual port addresses.
    • 在作为虚拟阵列呈现的逻辑存储单元组之间提供故障转移。 主虚拟阵列具有耦合到结构的至少一个主虚拟端口,每个主虚拟端口具有源虚拟端口名称和源虚拟端口地址。 辅助虚拟阵列具有耦合到该结构的一个或多个辅助虚拟端口,每个辅助虚拟端口具有辅助虚拟端口名称和虚拟端口地址。 驻留在主虚拟阵列上的所有数据都将复制到辅助虚拟阵列。 如果主虚拟阵列中发生故障,则辅助虚拟端口名称和LUN名称和数字将替换为主虚拟端口名称和LUN名称和数字。 Fabric更新其名称服务器数据库,以便数据库将主虚拟端口名称和LUN名称和数字与辅助虚拟端口地址相关联。

    • Data is transparently migrated between groups of logical units of storage presented as virtual arrays. A source virtual array has at least one source virtual port coupled to a fabric. Each source virtual port having a source virtual port name and a source virtual port address. A destination virtual array has one or more destination virtual ports coupled to the fabric, each destination virtual port having a destination virtual port name and a destination virtual port address. All data resident on the source virtual array is copied to the destination virtual array. The destination virtual port names and LUN names and numbers are then exchanged with the source virtual port names and LUN names and numbers. The fabric then updates its name server database so that the database associates the source virtual port name with the destination virtual port address.
    • 数据在呈现为虚拟阵列的逻辑存储单元组之间透明地迁移。 源虚拟阵列具有至少一个耦合到结构的源虚拟端口。 每个源虚拟端口具有源虚拟端口名称和源虚拟端口地址。 目的地虚拟阵列具有耦合到该结构的一个或多个目的地虚拟端口,每个目的地虚拟端口具有目的地虚拟端口名称和目的地虚拟端口地址。 驻留在源虚拟阵列上的所有数据都将复制到目标虚拟阵列。 然后将目标虚拟端口名称和LUN名称和数字与源虚拟端口名称和LUN名称和数字进行交换。 然后织物更新其名称服务器数据库,以便数据库将源虚拟端口名称与目标虚拟端口地址相关联。
