Abstract: A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O slot to a logical partition that is powering on and when removing the I/O slot from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of an I/O slot from, or return control to, an operating logical partition in order to facilitate hardware service operations on that I/O slot or on the physical enclosure in which it is contained.

Abstract: Techniques are disclosed for managing a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards, switch modules and a management controller. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards and the switch modules may be operatively connected to the midplane. The switch modules may be configured to switch network traffic for the one or more server cards. The management controller may be configured to manage the switch modules via the fabric interconnect.

Abstract: A resource and partition manager includes a power on/power off mechanism that is used to assure a hardware resource is powered down when control of the resource is removed from a logical partition, and to assure the hardware resource is powered up when control of the hardware resource is transferred to a logical partition. In the alternative, the resource and partition manager may simply place the hardware resource in a power on reset state when the hardware resource is transferred to a logical partition. In this manner, when made available to a partition, the hardware resource is in a power-on reset state, which is the state typically expected by the logical partition.

Abstract: An apparatus, program product and method utilize an event-driven communica- tions interface to support communications between multiple logical partitions (40, 42, and 44) in a logically-partitioned computer. The event-driven communications interface is at least partially disposed within a partition manager (46) that is accessible to each of the logical partitions (40, 42, and 44). Events are typically passed between logical partitions (40, 42, and 44) in the form of messages that are passed first from a source logical partition that initiates the event, through the partition manager (46), and then to a target logical par- tition to which the event is directed, while maintaining the independent address spaces associated with the logical partitions (40, 42, and 44).

Abstract: Un método para contabilizar el tiempo de uso de un procesador que da soporte a la ejecución concurrente de una pluralidad de hilos de hardware y que tiene una pluralidad de recursos usados por dicha pluralidad de hilos de hardware, comprendiendo el método: en cada ciclo de reloj de procesador, determinar el uso relativo de recursos en base a si cada hilo de hardware está o no en un estado particular de ciclo de procesador; y en respuesta a dicha determinación, actualizar una pluralidad de cuentas de uso de recursos de procesador, cada una de ellas asociada a un hilo particular de los hilos de hardware en conformidad con dicho uso relativo de recursos, caracterizado porque dicha actualización se realiza por igual en cada una de dicha pluralidad de dichas cuentas de uso de recursos de procesador en respuesta a la determinación de que ninguno de dicha pluralidad de hilos de hardware se encuentra en dicho estado particular de ciclo.
