Abstract: This invention discloses a storage virtualization subsystem and system with host-side redundancy via SAS connectivity. The I/O interconnect interface between the storage virtualization controller and the host is a serial-attached SCSI (SAS) interface. At least one SAS expander is inserted on the I/O interconnect path of the host side to provide the function of device expansion. Or, a built-in virtual SAS expander is disposed inside the storage virtualization controller to provide multiple virtual IDs for each SAS port. When one controller in the storage virtualization controller pair malfunctions or fails, the invention provides solutions in accord with different embodiments so that the surviving controller can inherit the ID of the failed one. Thus, the host can keep functioning normally as it is not aware of any change in the device status.

Abstract translation: 本发明公开了一种通过SAS连接具有主机侧冗余的存储虚拟化子系统和系统。 存储虚拟化控制器和主机之间的I / O互连接口是串行连接的SCSI（SAS）接口。 在主机侧的I / O互连路径上至少插入一个SAS扩展器，以提供设备扩展功能。 或者，内置虚拟SAS扩展器位于存储虚拟化控制器内部，为每个SAS端口提供多个虚拟ID。 当存储虚拟化控制器对中的一个控制器发生故障或故障时，本发明提供了根据不同实施例的解决方案，使得存活的控制器可以继承失败的控制器的ID。 因此，主机可以保持正常运行，因为它不知道设备状态有任何变化。

Abstract: A media area network (10) includes a storage system (16) having at least one storage device (18) for storing digitized information. A host bus (14) adapter provides a link between the storage system and a host system (12) that provides overall control of the media area network. Within the host bus adapter, a lower-level port driver (24) monitors communications between the storage system and the host bus adapter. In the event of a communications failure, the lower-level port driver initiates switching from a failed port to an alternative port, thereby achieving fail-over recovery. Allocating the responsibility for fail-over recovery to the lower-level port driver assures timely handling of port failures, thereby reducing potential latency delays.

Abstract: The storage system includes disk control clusters (1-1 to 1-n). Each cluster has channel IF units (11), disk IF units (16) and local shared memory units. The channel IF units, disk IF units and local shared memory units in the plurality of disk control clusters are connected to each other across the disk control clusters by interconnection (31), global information control unit (21) for storing management information about the disk control clusters is connected to the interconnection. Host computers (2) and the channel IF units of the disk control clusters are connected via front-end switch (7) for storing copy of the management information. Since the front-end switch reflects the contents of the copy of the management information on routing table, an access request from the host computer can be sent to a suitable disk control cluster.

Abstract: The present invention provides a file system capable of reducing time taken to switch I/O paths, and hiding the process of switching the I/O paths from the user.
In a system of the present invention in which a file ID is defined for each file, upon receiving a request for accessing a file specifying a file ID from a user, a file server refers to a file management table to obtain a logical disk ID for accessing the file. The file server then refers to a logical disk management table to obtain an I/O path corresponding to the logical disk ID, and accesses a physical disk device by use of the obtained I/O path. When a fault has occurred in an operational I/O path, a file server rewrites the logical disk management tables in all nodes to change the I/O path.

Abstract: Le système comprend une unité centrale (CPU) associée à un ou plusieurs contrôleurs d'entrée-sortie (Ctl 1 -Ctl 4 ) et un sous-système de disques à redondance (MD), divisés en unités logiques et sous la commande de deux contrôleurs de disques redondants (SP-A, SP-B). Ceux-ci sont attachés au(x) contrôleur(s) d'entrée-sortie par des bus également redondants. Une première partie des unités logiques est assignée au premier contrôleur de disques (SP-A) et l'autre partie au second contrôleur de disques (SP-B). Lorsqu'une unité logique, assignée au premier contrôleur de disque (SP-A), est accédée, l'état du second contrôleur de disque (SP-B) est surveillé par le chemin de réserve. En cas de détection de défaillance du second contrôleur de disques (SP-B), toutes les unités logiques sont basculées sur le premier (SP-A) et lui sont assignées. Un mode de fonctionnement dégradé est initié et l'accès aux ressources s'effectue par le chemin de réserve.
Applicable aux systèmes de traitement de données.
