    摘要： 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.

    摘要： An impact of configuration changes on controllers is projected, in a computing environment including one or more bridge attached channels. This projection quantifies the impact for each controller affected by the change, such that it is known by a quantifiable value how much the change impacts the controller. In order to project the impact, a projected I/O velocity of the controller is determined. In making the projections, pseudo channels associated with a particular bridge attached channel are modelled as independent channels. Alternatively, a utilization metric of a bridge attached channel is determined and compared to a threshold; pseudo channels associated with the bridge attached channel are modelled as independent channels if the utilization metric is below the threshold.

    摘要： 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.

    摘要： Allocation of shareable resources of a computing environment are dynamically adjusted to balance the workload of that environment. Workload is managed across two or more partitions of a plurality of partitions of the computing environment. The managing includes dynamically adjusting allocation of a shareable resource of at least one partition of the two or more partitions in order to balance workload goals of the two or more partitions.
