    摘要： A method, system, and computer program product are disclosed within a logically partitioned data processing system for providing an aliased queue pair for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.

    摘要： An information processing system is provided which includes a plurality of system resources, and an event queue having a predetermined number of entries. An event recording mechanism of the information processing system is operable to make entries regarding events in the event queue, wherein the entries are limited to a predetermined number of active entries in the event queue per each type of event per each of the system resources. In a particular embodiment, the number of entries per each type of event for each of the system resources is limited to one.

    摘要： Performance counters are provided for virtualized network interfaces of communications networks, while minimizing the use of hardware resources. A virtualized network interface includes physical resources, as well as logical resources. Dedicated performance counters are provided for the physical resources of the virtualized network interface, as well as for logical partitions coupled to that interface, while non-dedicated performance counters are provided for the logical resources. This enables the provision of performance counters for virtualized network interfaces, while minimizing hardware resources consumed by those interfaces.

    摘要： A method and system are disclosed for logically partitioning resources of a single channel adapter for use in a system area network. Each resource includes a partition identifier register within which is stored a partition identifier. A first one of the resources is assigned to a first partition by storing a first partition identifier in the partition identifier register within the first one of the resources. A second one of the resources is assigned to a second partition by storing a second partition identifier in the partition identifier register within the second one of the resources. Partitioning of the resources is enforced by permitting access to the first resource by only the first partition and permitting access to the second resource by only the second partition by checking the partition identifiers of each resource.

    摘要： A Host Channel Adapter supporting a plurality of Logical Partitions is provided. A Subnet Manager, having an associated aliased Queue Pair, may run in a Logical Partition. A single physical subnet management Queue Pair and its associated firmware are provided for each physical port in the Host Channel Adapter. If a packet is to be routed to a Subnet Manager residing in a Logical Partition, the packet is enqueued on the physical port's send queue for transmission to the aliased Queue Pair for the Subnet Manager. The Host Channel Adapter hardware loops the packet back to the aliased Queue Pair in the appropriate Logical Partition. The aliased Queue Pair is also capable of transmitting packets that are looped back to a Hypervisor Subnet Management Agent.

    摘要： A method, apparatus and computer program product are provided for implementing dynamic Virtual Lane buffer reconfiguration in a channel adapter. A first register is provided for communicating an adapter buffer size and allocation capability for the channel adapter. At least one second register is provided for communicating a current port buffer size and one second register is associated with each physical port of the channel adapter. A plurality of third registers is provided for communicating a current VL buffer size, and one third register is associated with each VL of each physical port of the channel adapter. The second register is used for receiving change requests for adjusting the current port buffer size for an associated physical port. The third register is used for receiving change requests for adjusting the current VL buffer size for an associated VL.
