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： 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： Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

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： 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.
