摘要： A method to enable a user mode process to operate in a privileged execution mode is disclosed. Applicants' method provides an operating system comprising a privileged execution mode and a non-privileged execution mode, and a plurality of user mode strings operating in the non-privileged execution mode. The computing device receives a request from a first user mode string to operate in the privileged execution mode to perform one or more designated tasks. Applicants' method authorizes the first user mode string to operate in the privileged execution mode, and the first user mode string performs those one or more designated tasks using the privileged execution mode. Applicants' method continues to permit the first user mode string to operate in the privileged execution mode after completion of the one or more designated tasks.

摘要： In managing multiprocessor operations, a first processor repetitively reads a cache line wherein the cache line is cached from a line of a shared memory of resources shared by both the first processor and a second processor. Coherency is maintained between the shared memory line and the cache line in accordance with a cache coherency protocol. In one aspect, the repetitive cache line reading occupies the first processor and inhibits the first processor from accessing the shared resources. In another aspect, upon completion of operations by the second processor involving the shared resources, the second processor writes data to the shared memory line to signal to the first processor that the shared resources may be accessed by the first processor. In response, the first processor changes the state of the cache line in accordance with the cache coherency protocol and reads the data written by the second processor. Other embodiments are described and claimed.

摘要： An apparatus, system, and method are disclosed for selecting a space efficient repository. A cache receives write data. A destage module destages the data sequentially to a coarse grained repository such as a stride level repository and destages a directory entry for the data to a coarse grained directory such as a stride level directory if the data satisfies a repository policy. In addition, the destage module destages the data to a fine grained repository such as a track level repository overwriting an existing data instance and destages the directory entry to a fine grained directory such as a track level directory if the data does not satisfy the repository policy.

摘要： Disclosed are a storage controller, and a method of operating a storage controller, for interfacing between host systems and a storage devices system. The storage controller includes a first cluster including a first processor and a first cache, and a second cluster including a second processor and a second cache. The method comprises the step of directing data from the host systems through first and second data paths to the storage system. The first processor and cache are associated with the first data path, and the second processor and cache are associated with the second data path. Under one set of conditions, the controller enters a failover mode, wherein data directed to the first data path are routed to the second data path. Under another set of conditions, the controller deconfigures the first cache without entering the failover mode.

摘要： A method to rebuild an NVS image is disclosed. The method provides information to a first cluster of an information storage and retrieval system, and writes that information to a non-volatile storage device disposed in a second cluster. Upon losing utility power to all or part of the information storage and retrieval system, the method provides back-up power to a processor and a data cache, and determines if the information written to the second non-volatile storage device is accessible. If the information written to the second non-volatile storage device is accessible, then the method copies the image of that second non-volatile storage device to an external storage device. If the information written to said second non-volatile storage device is not accessible, then the method creates a virtual NVS image using the information disposed in a local data cache, and copies that virtual NVS image to an external storage device.

摘要： A data storage control unit is coupled to one or more host devices and to one or more physical storage units. Data is stored in one of the storage units and, for data integrity, copied to another storage unit. An updated state of the copy process (metadata) is maintained and updated in metadata tracks in a memory of the storage controller and periodically destaged to corresponding metadata tracks of a storage unit. If the copy process is interrupted, such as by a power failure, an error handling routine commences. Track state fields associated with each in-memory metadata track are initialized to an ‘invalid’ state and background staging of metadata tracks from the storage unit to the memory. After a track is staged, the associated track state field is changed to a ‘valid’ state. If a request is received to access a track of copy state data and the track has been staged (as indicated by the state of the associated track state field), the track is accessed. If the requested track has not been staged, requester waits while the requested track is staged; then the requested track is accessed. Once the error handling routine is completed, normal I/O operations with customer data may resume. Preferably, completion of the error handling routine is independent of the completion of the staging of copy state data tracks.
摘要翻译：数据存储控制单元耦合到一个或多个主机设备和一个或多个物理存储单元。数据存储在其中一个存储单元中，为了数据的完整性，数据被复制到另一个存储单元。复制过程（元数据）的更新状态在存储控制器的存储器中的元数据轨道中被维护和更新，并且周期性地转移到存储单元的相应元数据轨道。如果复制过程中断，例如电源故障，则会启动错误处理例程。与每个存储器间元数据轨道相关联的跟踪状态字段被初始化为从存储单元到存储器的元数据轨迹的“无效”状态和背景分段。在轨道分段后，相关的轨道状态字段将更改为“有效”状态。如果接收到访问复制状态数据的轨道的请求，并且轨道已经被分段（如由相关联的轨道状态字段的状态所指示的），则该轨道被访问。如果所请求的轨道尚未分段，则请求者在所请求的轨道分段时等待; 然后访问所请求的轨道。一旦完成了错误处理程序，可以恢复与客户数据的正常I / O操作。优选地，错误处理例程的完成与复制状态数据轨道的分段的完成无关。
