Abstract: A method is provided for regulating access to a data storage configuration that includes a storage controller, a number of disk storage drives usefully configured as a RAID array, and a backend bus connected between the storage controller and the drives. One or more backend expansion ports are also connected to the backend bus, for use in expanding storage capacity as required. In accordance with the method, if a host device is inadvertently connected to a backend expansion port, rather than to an intended host connection port, an algorithm is implemented, preferably in a backend processor connected between the backend bus and the drives. The WWN of the host, received during a login procedure, is examined to determine whether or not the host is an authorized user of the storage configuration. If not, the backend processor is operated to prevent the host from accessing the drives, to prevent corruption of stored data.

Abstract translation: 提供了一种用于调节对数据存储配置的访问的方法，该数据存储配置包括存储控制器，有用地配置为RAID阵列的多个磁盘存储驱动器以及连接在存储控制器和驱动器之间的后端总线。 一个或多个后端扩展端口也连接到后端总线，用于根据需要扩展存储容量。 根据该方法，如果主机设备无意中连接到后端扩展端口而不是连接到预期的主机连接端口，则优选地在连接在后端总线和驱动器之间的后端处理器中实施算法。 检查在登录过程期间接收到的主机的WWN以确定主机是否是存储配置的授权用户。 如果不是，则后端处理器用于防止主机访问驱动器，以防止存储的数据损坏。
