Abstract: The storage virtualization switch is capable of omitting to control (exclusion-control) a reserve condition on a physical storage unit without decreasing fault tolerance and reliability, so that overhead of access to the storage unit can be smaller. The storage virtualization switch comprises: a storage virtualization unit for constituting a virtual storage unit by using a storage area of the physical storage unit; a communication unit for communicating with another storage virtualization switch; and a zoning unit for making a host computer recognize an external virtual storage unit constituted in another storage virtualization switch connected by the communication unit, the zoning unit making the host computer access the external virtual storage unit via the communication unit when the host computer requests to access the virtual storage unit.

Abstract: An object of the present invention is to provide a means for detecting a logical command error, and a storage system and its control method that can properly perform error handling, and detection and blockage of a malfunctioning section. A storage control system includes controller units 130A and 130B for performing processing for data I/O to/from drives 150 and 160 in response to a data I/O request from a host device 100, switches 140A and 140B connecting the controller units 130A and 130B and the drives 150 and 160, and a port selector 300 inserted between the switches 140A and 140B and the drive 160. The port selector 300, when receiving a command generated based on processing performed by an MPU 131, accesses a target drive 160 if that data that forms a command is valid. Meanwhile, if the port selector 300 detects logical command inconsistency, the port selector 300 forwards that detection result to the MPU 131 via the switch 140A or 140B and requests retry processing from the MPU 131.

Abstract translation: 本发明的目的是提供一种用于检测逻辑命令错误的装置，以及可以适当地执行错误处理以及故障部分的检测和阻塞的存储系统及其控制方法。 存储控制系统包括响应于来自主机设备100的数据I / O请求而执行到/从驱动器150和160的数据I / O处理的控制器单元130A和130B，连接 控制器单元130A和130B以及驱动器150和160以及插入在开关140A和140B之间的端口选择器300和驱动器160。 端口选择器300在接收到由MPU 131执行的处理产生的命令时，如果形成命令的数据有效，则访问目标驱动器160。 同时，如果端口选择器300检测到逻辑命令不一致，则端口选择器300经由开关140A或140B将该检测结果转发给MPU 131，并请求从MPU 131重试处理。

Abstract: For each RAID group to be determined for blocking, each disk is classified into three types of totalization unit based on the status of each disk belonging to the RAID group or the presence/absence of an access path to each disk, and the number of disks corresponding to each totalization unit is totalized. The totalization unit is a “used disk”, an “unused disk”, and a “loop-down disk”. The totalization result is compared with the threshold condition set for each RAID level (for example, “unused disk”=0 and “loop-down disk”=‘1 or more’), and the blocking possibility is determined.

Abstract: For a storage area network, verification of path selection protocol comprises disabling a switch port on a switch of the primary path of a data storage device; initiating an input/output command to the device; verifying that a failover occurred. The switch port for the primary path is enabled, an “immediate” input/output command is initiated to the device with the “immediate” bit set; and, in response to a notification by the device resulting from the “immediate” bit, a switch port is disabled on the switch of the primary path for the device; and the method verifies that a failover occurred.

Abstract: A system for a host-based RAID solution in a shared storage environment is provided in which the compute blades of a system are coupled to one or multiple concentrators. The concentrators serve as a switch or expander to couple each of the compute blades to a shared storage resource. Within the shared storage resource, a set drives is configured in a RAID array. The shared disk drives are partitioned so that each partition is dedicated one of the compute blades of the system. Multiple sets of drives may be used so that the collective set of drives can be configured as part of a RAID volume that includes mirroring between at least two of the drive of the RAID volume, such as RAID 1 or RAID 0+1, in which each set of drives is a mirror of the other set of drives and the content associated with each of the compute blades is striped across multiple of the drives in each of the two sets of drives.

Abstract: The splitting of storage applications and functions into a control path (CP) component and a data path (DP) component is disclosed. Reads and writes may be handled primarily in the DP. The CP may be responsible for discovery, configuration, and exception handling. The CP can also be enabled for orchestrating complex data management operations such as snapshots and migration. Storage virtualization maps a virtual I/O to one or more physical I/O. A virtual target (vTarget) in the virtual domain is associated with one physical port in the physical domain. Each vTarget may be associated with one or more virtual LUNs (vLUNs). Each vLUN includes one or more vExtents. Each vExtent may point to a region table, and each entry in the region table may contain a pointer to a region representing a portion of a pExtent, and attributes (e.g. read/write, read only, no access) for that region.

Abstract translation: 公开了将存储应用和功能分解成控制路径（CP）组件和数据路径（DP）组件。 读写可能主要在DP中处理。 CP可能负责发现，配置和异常处理。 也可以启用CP来编排复杂的数据管理操作，如快照和迁移。 存储虚拟化将虚拟I / O映射到一个或多个物理I / O。 虚拟域中的虚拟目标（vTarget）与物理域中的一个物理端口相关联。 每个vTarget可能与一个或多个虚拟LUN（vLUN）相关联。 每个vLUN包括一个或多个vExtents。 每个vExtent可以指向区域表，并且区域表中的每个条目可以包含指向表示pExtent的一部分的区域的指针，以及该区域的属性（例如，读/写，只读，无访问）。

Abstract: Provided is a computer system including at least one host computer; and at least one storage system, characterized in that: the storage system has a disk drive and a disk controller, and provides a storage area of the disk drive as at least one logical unit; upon detecting a failure in a logical path serving as an access route from the host computer to the logical unit, the host computer specifies logical paths for accessing the same logical unit that is connected to the logical path where the failure is detected; the host computer executes failure detecting processing for the specified logical paths to judge whether the specified logical paths are normal or not; the host computer selects normal logical paths out of the specified logical paths; and the host computer accesses the logical unit via the normal logical paths selected.

Abstract: A circuit arrangement, method and apparatus utilize communication links that are selectively configurable to operate in both unidirectional and bidirectional modes to communicate data between multiple nodes that are interconnected to one another in a daisy chain configuration. As a result, in many instances communications may be maintained with nodes located both before and after a discontinuity in a daisy chain configuration.

Abstract: A system and method enables a file server, to support multi path input/output operations for Fibre Channel devices. Upon each Fibre Channel Arbitrated Loop initialization event generated, the system and method updates a path and device instance to track multiple paths to a given device. While the file server is attempting input/output operations, the failure of a given path can be corrected by the use of another path associated with a given device. The data structures generated by the low levels of the storage operating system are exposed for use by upper level services for routing a storage device identification purposes.
