Abstract: In a storage server on a storage area network, a media unit manager manages disk space in a manner transparent to the host computers. The media unit manager uses media units corresponding to the physical storage devices on the storage area network to build higher-level media units. The higher level media units can have the attributes of being sliced, concatenated, mirrored, striped, etc. Thus, the host computers need not be aware of the specific physical storage devices themselves, reducing the management and reconfiguration burden on the host computers when storage devices are added to or removed from the storage area network.

Abstract translation: 在存储区域网络中的存储服务器中，媒体单元管理器以对主计算机透明的方式管理磁盘空间。 媒体单元管理器使用与存储区域网络上的物理存储设备相对应的媒体单元来构建更高级别的媒体单元。 较高级别的媒体单元可以具有切片，连接，镜像，条带化等属性。因此，主机计算机不需要自己了解特定的物理存储设备，从而减少存储时主机上的管理和重新配置负担 设备被添加到存储区域网络或从存储区域网络中移除。

Abstract: A computer system may include one or more hosts and a plurality of data storage devices for providing multihop system calls. The data storage devices are interconnected and also connected to the one or more hosts. Each data storage device classifies a data operation as a system call, a remote system call, or a multihop system call. Also described is a multipath multihop system call in which one or more communication paths may be selected using predetermined and/or dynamic communication path selection techniques. The number of communication paths determined may be in accordance with parameters that are included in a multipath multihop system call, tunable system parameters, or a combination of the foregoing.

Abstract: A fail-over switch (100, 102) for use in a data storage system that connects each of a plurality of data storage devices (112) to each of two communication paths (126, 128). The switch (100, 102) may route requests to either of the two communication paths (126, 128). Switching may be accomplished by two switches (100, 102) connected to each other and each in connection with one of the two communication paths (126, 128). With one data storage controller (90) in communication with the data storage devices (112) over a first path (126) and a second data storage controller (92) in communication with the data storage devices (112) over a second path (128), the fail-over switch (100, 102) may be used upon detection of a malfunction on one path to switch a controller into connection with the remaining operable path so as to share that path with the other controller.
