摘要： A method is provided for a data processing system configured to include multiple logical partitions, wherein resources of the system are selectively allocated among respective partitions. In the method, an entity such as a Partition Load Manager or a separate background process is used to manage resources based on locality levels. The method includes the step of evaluating the allocation of resources to each of the partitions at a particular time, in order to select a partition having at least one resource considered to be of low desirability due to its level of locality with respect to the selected partition. The method further comprises identifying each of the other partitions that has a resource matching the resource of low desirability, and determining the overall benefit to the system that would result from trading the resource of low desirability for the matching resource of each of the identified partitions. Resources are reallocated to trade the resource of low desirability for the matching resource of the identified partition that is determined to provide the greatest overall benefit for the system, provided that at least some overall system benefit will result from the reallocation.
摘要翻译：提供了一种用于数据处理系统的方法，所述数据处理系统被配置为包括多个逻辑分区，其中所述系统的资源在各个分区之间被选择性地分配。在该方法中，使用诸如分区加载管理器或单独的后台进程的实体来基于地点级别来管理资源。该方法包括在特定时间评估对每个分区的资源分配的步骤，以便由于其相对于所选择的分区的局部性水平而选择具有被认为是低可取性的至少一个资源的分区。该方法还包括识别具有与低可靠性的资源匹配的资源的每个其他分区，以及确定由对于每个所识别的分区的匹配资源的低期望性的资源进行交易而导致的系统的总体利益。重新分配资源以交换被确定为系统提供最大整体利益的所识别分区的匹配资源的低可用性资源，前提是至少部分整体系统利益将由重新分配产生。

摘要： A method, system, and program for managing memory page requests in a multi-processor data processing system determines a threshold value of available memory, and dynamically adjusts an allocation time to fulfill a page request if the available memory is below a threshold value. The allocation time to fulfill the page request is based upon a percentage of available memory pages once a page stealer commences a scan for pages. An allocation wait time is inversely proportionally adjusted depending upon the percentage of available memory. The allocation wait time has a duration that increases in time as the percentage of available memory decreases and decreases in time as the percentage of available memory increases. More specifically, an average time per page to allocate a page including a scan time for the scan in computing the average time is determined. Then a tunable value is applied to the average time to determine a wait time. In a preferred embodiment, user defined values are received that would control the allocation wait time before fulfilling a page request.

摘要： Described is a method and system for transparently migrating data between storage systems of a computing environment without disrupting realtime access to the stored data of the storage systems. Specifically, when adding a new storage system to the computing environment, realtime data write operations can be redirected to the new storage system instead of an existing storage system. During the redirection, the data stored on the existing storage system can be accessed for data operations. Concurrently, during the redirection, data stored on the existing storage system can be migrated to the new storage system. When the data migration completes and all the data, stored on the existing storage system prior to the redirection, resides on the new storage system, the new storage system can function as the primary storage system. Thus, storage capacity can increase or be replaced without disrupting data operations.
