    • A technique is disclosed for managing a workload distributed across multiple data processing systems to enhance shared resource access to meet a common performance standard. The technique includes on at least one system, measuring performance of the work units on the system to create local performance data, and on at least some of the systems sending the local performance data to at least one other system of the multiple data processing systems. The method further includes on at least one of the systems, receiving the performance data from the sending systems to create remote performance data, and adjusting at least one control parameter for accessing shared resources in response to the local and remote performance data to modify the performance of the work units distributed across the data processing systems to achieve the common performance standard. A dynamic resource clustering process is also employed to enhance the shared resource management.
    • 公开了一种用于管理分布在多个数据处理系统上的工作负载以增强共享资源访问以满足公共性能标准的技术。 该技术包括至少一个系统,测量系统上的工作单元的性能以创建本地性能数据,以及在至少一些将本地性能数据发送到多个数据处理系统的至少一个其他系统的系统中。 该方法还包括在至少一个系统中,从发送系统接收性能数据以创建远程性能数据,以及响应于本地和远程性能数据调整用于访问共享资源的至少一个控制参数以修改性能 的工作单位分布在数据处理系统中实现共同的性能标准。 动态资源聚类过程也用于增强共享资源管理。

    • Disclosed is a method and computer program device for dynamically managing the assignment of alias addresses to base addresses referencing an input/output (I/O) device, such as a direct access storage device (DASD). Two distinct methods are disclosed. In one method, alias addresses are assigned based on the performance of the I/O devices. In this method, alias addresses are assigned to highly utilized devices, as indicated by device performance data, in order to maximize the efficient utilization of I/O device resources. In a second method, workload management principles are utilized to assign alias addresses. In this method, a correlation is made between each I/O device and the service classes utilizing each device. As in the first method, performance data is generated for each I/O device. Alias addresses are assigned to I/O devices experiencing queue delays as indicated by their performance data, if the device is associated with a service class that has failed to meet one or more processing goals. These methods may operate on a single host, or in a multi-host environment. The methods may be operated individually, or concurrently. Methods are disclosed to manage contention between concurrently operating assignment methods, and between multiple hosts concurrently operating one or more assignment methods.
    • 公开了一种用于动态管理参考诸如直接存取存储设备(DASD)的输入/输出(I / O)设备的基地址的别名地址分配的方法和计算机程序设备。 公开了两种不同的方法。 在一种方法中,根据I / O设备的性能分配别名地址。 在这种方法中,别名地址被分配给高度利用的设备,如设备性能数据所示,以便最大化I / O设备资源的有效利用。 在第二种方法中,使用工作负载管理原则来分配别名地址。 在这种方法中,每个I / O设备和使用每个设备的服务类别之间进行相关。 与第一种方法一样,为每个I / O设备生成性能数据。 如果设备与不符合一个或多个处理目标的服务类相关联,则别名地址被分配给遇到队列延迟的I / O设备,如性能数据所示。 这些方法可以在单个主机或多主机环境中运行。 这些方法可以单独操作或同时操作。 公开了用于管理并发操作分配方法之间的争用以及同时操作一个或多个分配方法的多个主机之间的争用的方法。

    • A method and apparatus for enforcing capacity limitations such as those imposed by software license agreements in an information handling system in which a physical machine is divided into a plurality of logical partitions, each of which is allocated a defined portion of processor resources by a logical partition manager. A software license manager specifies a maximum allowed consumption of processor resources by a program executing in one of the logical partitions. A workload manager also executing in the partition measures the actual consumption of processor resources by the logical partition over a specified averaging interval and compares it with the maximum allowed consumption. If the actual consumption exceeds the maximum allowed consumption, the workload manager calculates a capping pattern and interacts with the logical partition manager to cap the actual consumption of processor resources by the partition in accordance with the calculated capping pattern. To provide additional capping flexibility, partitions are assigned phantom weights that the logical partition manager adds to the total partition weight to determine whether the partition has exceeded its allowed share of processor resources for capping purposes. The logical partition thus becomes a “container” for the licensed program with an enforced processing capacity less than that of the entire machine.
    • 一种用于执行容量限制的方法和装置,例如在信息处理系统中由软件许可协议强加的容量限制,其中物理机被分成多个逻辑分区,每个逻辑分区通过逻辑分区被分配给定义的处理器资源部分 经理。 软件许可证管理器通过在其中一个逻辑分区中执行的程序指定处理器资源的最大允许消耗。 还在分区中执行的工作负载管理器通过逻辑分区在指定的平均间隔内测量处理器资源的实际消耗,并将其与最大允许消耗进行比较。 如果实际消耗超过允许的最大消耗量,则工作负载管理器计算上限模式,并与逻辑分区管理器进行交互,以根据计算的上限模式来限制分区的处理器资源的实际消耗。 为了提供额外的上限灵活性,分区被分配幻影权重,逻辑分区管理器添加到总分区权重,以确定分区是否超过其允许的处理器资源份额以进行封顶。 因此,逻辑分区成为许可程序的“容器”,其强制处理能力小于整个机器的处理能力。
