摘要： A method for allocating space in a cache based on media I/O speed is disclosed herein. In certain embodiments, such a method may include storing, in a read cache, cache entries associated with faster-responding storage devices and cache entries associated with slower-responding storage devices. The method may further include implementing an eviction policy in the read cache. This eviction policy may include demoting, from the read cache, the cache entries of faster-responding storage devices faster than the cache entries of slower-responding storage devices, all other variables being equal. In certain embodiments, the eviction policy may further include demoting, from the read cache, cache entries having a lower read-hit ratio faster than cache entries having a higher read-hit ratio, all other variables being equal. A corresponding computer program product and apparatus are also disclosed and claimed herein.

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 data write/read auxiliary device and method for writing/reading data are provided. A data storage unit and a program storage unit are installed in the data write/read auxiliary device, wherein the program storage unit is for storing automatic execution program and protection program. When the data write/read auxiliary device is connected to a data processing device, the automatic execution program is executed for automatically executing programs stored in the program storage unit. The protection program is executed for executing an access process on data storage unit to judge whether driving a write/read head or not based on outcome of the access process when a file sharing software is executed for data downloading and uploading. Through the data storage unit as a buffer area of data before writing/reading data on a hard disk, the data write/read auxiliary device and method for writing/reading data can protect the hard disk.

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.
摘要翻译：在管理多处理器操作时，第一处理器重复地读取高速缓存行，其中高速缓存行从由第一处理器和第二处理器共享的资源的共享存储器的一行缓存。根据高速缓存一致性协议，在共享存储器线和高速缓存线之间保持一致性。在一个方面，重复的高速缓存行读取占用第一处理器并且禁止第一处理器访问共享资源。在另一方面，在由涉及共享资源的第二处理器完成操作之后，第二处理器将数据写入共享存储器线，以向第一处理器通知第一处理器可以访问共享资源。作为响应，第一处理器根据高速缓存一致性协议改变高速缓存行的状态，并读取由第二处理器写入的数据。描述和要求保护其他实施例。

摘要： A delay interval is calculated for a processor that attempts to reserve a reserved shared resource in a multiprocessing system. The delay interval is based on the relationship of a requesting processor and a reservation holding processor. Each delay interval is unique without consistent bias against a processor. The requesting processor queries the reservation status of a shared resource without invalidating an existing reservation. If a shared resource is reserved, the requesting processor waits for an amount of time corresponding to the delay interval before again attempting to reserve the shared resource. The present invention substantially reduces arbitration conflicts within multiprocessor systems.
摘要翻译：对于尝试在多处理系统中预留共享资源的处理器，计算延迟时间间隔。延迟间隔基于请求处理器和预约保持处理器的关系。每个延迟时间间隔是唯一的，没有对处理器的一致的偏置。请求处理器在不使现有预留失效的情况下查询共享资源的预留状态。如果共享资源被保留，则请求处理器在再次尝试保留共享资源之前等待与延迟时间相对应的时间量。本发明大大减少了多处理器系统内的仲裁冲突。

摘要： Method for selectively clearing persistent data such as metadata in a storage subsystem. The method includes identifying one or more metadata tracks to clear, receiving a request from a client to clear the identified metadata tracks, passing the request to a storage device driver, and clearing the identified metadata tracks. The metadata tracks to be cleared may be identified by a specific storage function associated with the metadata to be cleared or by a specific storage target associated with metadata. Alternatively, both a storage function and a storage target may be specified. Preferably, the request to clear one or more identified metadata tracks may be executed without affecting unrelated storage functions. In addition, the request may be executed while preserving metadata tracks unrelated to the identified metadata tracks. Thus, execution of a request to selectively clear identified global metadata tracks in accordance with the present invention will typically not cause the loss of configuration information and will not necessitate a reboot of the system. In addition, a request as described above may be executed at any point in time while the storage system is running.
摘要翻译：用于选择性地清除诸如存储子系统中的元数据的持久性数据的方法。该方法包括识别一个或多个元数据轨道以清除，接收来自客户端的请求以清除所识别的元数据轨道，将请求传递到存储设备驱动器，以及清除所识别的元数据轨道。要清除的元数据轨迹可以通过与要清除的元数据或与元数据相关联的特定存储目标相关联的特定存储功能来识别。或者，可以指定存储功能和存储目标。优选地，可以执行清除一个或多个所识别的元数据轨道的请求而不影响不相关的存储功能。此外，可以在保留与所识别的元数据轨道无关的元数据轨道的同时执行请求。因此，根据本发明的执行选择性地清除所标识的全局元数据轨迹的请求通常不会导致配置信息的丢失，并且不会使系统重新启动。此外，当存储系统运行时，可以在任何时间点执行如上所述的请求。

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.
