摘要： An apparatus for improving the reliability of host data stored on Fiber Channel attached storage subsystems by performing end-to-end data integrity checks. When a read or write operation is initiated, an initial checksum for data in the read/write operation is generated and associated with the data, wherein the association exists through a plurality of layers of software and attached storage subsystems. The initial checksum is passed with the data in the read/write path. When a layer of software in the read/write path receives the initial checksum and data, the layer performs an integrity check of the data, which includes generating another checksum and comparing it to the initial checksum. If the checksums do not match, the read/write operation fails and the error is logged. If the checksums match, the integrity check is repeated through each layer in the read/write path to enable detecting data corruption at the point of source.

摘要： A method, system and computer program product are provided for representing resource sets in a variable format. Variable resource sets are represented in two parts: a system topology domain and a system detail level. Logical entities are allowed to consume variable resource sets to specify the domain and level required in the attachment. Thus, the resource set attachment is made using a domain system detail level, but the actual resources represented are derived dynamically. That is, the elements that were once statically represented by bits in the resource set are now derived dynamically to reflect the system state at the time they are being used.

摘要： A method, apparatus, and computer program product for storage pools with write atomicity. An abstraction manager enforces write atomicity and disallows options which are inconsistent with write atomicity. The abstraction manager constructs through a physical device interface a logical continuous view of a storage pool in a manner consistent with write atomicity. Applications collect information specific to write atomicity from the abstraction manager through an application interface.

摘要： The present invention provides an apparatus, method and computer program product for privatizing operating system data. With the apparatus, method and computer program product of the present invention, a block of memory is allocated and divided into identical, smaller, properly aligned storage areas, each dedicated to a single processor in a multiprocessor system. The storage areas are allocated either initially when the system is initialized or on an as needed basis. Each sub-allocation request is made to use storage at the same location relative to the start of that processor's storage space. Because each processor's storage is isomorphic to all other processors, only one allocation record for all processors is needed, thereby reducing the overhead of the data privatization scheme. By allocating memory in this manner, cache line contention is minimized.

摘要： In a data processing system utilizing multiple page sizes for virtual memory paging, a system, method, and article of manufacture for managing page replacement. In one embodiment, the page replacement method begins with a page frame allocation request, such as may be generated following a page fault. A page replacement procedure is invoked to select one or more pages to be replaced by the requested page(s). In a preferred embodiment, the page replacement includes a step of selecting, in accordance with a page type allocation of at least one of the multiple page sizes, a page size to be utilized for page replacement for the page frame allocation request.

摘要： A system and method of allocating contiguous real memory in a data processing system. A memory controller within system memory receives a request from a data processing system component for a contiguous block of memory during operation of the data processing system. In response to receiving the request, the memory controller selects a candidate contiguous block of memory. Then, after temporarily restricting access to the candidate contiguous block of memory, the memory controller identifies a set of frames currently in use within the candidate contiguous block of memory, relocates the set of frames, and allocates the candidate block of memory for exclusive use by the requesting data processing component. The allocation of contiguous real memory occurs dynamically during the operation of the data processing system.

摘要： A computer implemented method, apparatus, and computer program product for dynamically loading a module into an application address space. In response to receiving a checkpoint signal by a plurality of threads associated with an application running in a software partition, the plurality of threads rendezvous to a point outside an application text associated with the application. Rendezvousing the plurality of threads suspends execution of application text by the plurality of threads. The application text is moved out of an application address space for the application to form an available application address space. The available application address space is an address space that was occupied by the application text. A software module is moved into the available application address space.

摘要： A method and system for enabling dynamic matching of storage utilization characteristics of a host system application with the characteristics of the available storage pools of an attached distributed storage system, in order to provide an optimal match between the application and selected storage pool. An abstraction manager is provided, enhanced with a storage device configuration utility/module, which performs a series of tasks to (1) obtain/collect the correct configuration information from each connected storage device or storage pools and/or (2) calculate the configuration information when the information is not readily available. The storage device configuration module then normalizes, collates and matches the configuration information to the various applications running on the host system and/or outputs the information to a user/administrator of the host system via a software interface. By using the collected/calculated configuration information, applications are assigned to an optimal storage pool in an intelligent and efficient manner.
