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.
摘要翻译：公开了用于逻辑地划分用于系统区域网络的单个信道适配器的资源的方法和系统。每个资源包括分区标识符寄存器，其中存储有分区标识符。通过将第一分区标识符存储在第一资源内的分区标识符寄存器中，将资源中的第一个分配给第一分区。通过在第二个资源中的分区标识符寄存器中存储第二分区标识符来将第二个资源分配给第二分区。通过仅通过第一分区允许对第一资源的访问来执行资源的分区，并且通过检查每个资源的分区标识符来允许仅通过第二分区访问第二资源。

摘要： An apparatus, system and method for providing multiple logical partitions in a system area network are provided Logical partitioning support is provided for host channel adapters which allows multiple operating systems to share the resources of a single physical host channel adapter (HCA). The apparatus, system and method ensures that each operating system is unaware that the HCA hardware resources are being shared with other operating systems and further guarantees that the individual operating systems are prevented from accessing HCA hardware resources which are associated with other operating systems.

摘要： An aliased queue pair is provided within a logically partitioned data processing system 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： The present invention provides an apparatus, system and method for providing a generalized queue pair for use with host channel adapters of a system area network. With the apparatus, system and method, the hypervisor of a host channel adapter maintains a P_Key table for each logical port of the host channel adapter. When a request is received to allocate a queue pair from a requestor application associated with a logical port, a P_Key mode is set in a control register associated with the queue pair based on the type of requestor application that sent the request. Based on this P_Key mode, one or more P_Keys from a P_Key table associated with the logical port from which the request was received are written to one or more P_Key registers allocated to the queue pair. These P_Keys are then used to perform P_Key checks of incoming data packets. In addition, these P_Keys are inserted into headers of outgoing data packets. In a preferred embodiment, the P_Key modes may be a single P_Key check mode, a multiple P_Key check mode, and a P_Key check disabled mode.

摘要： A method, system and program for controlling access to memory areas within a computer are provided. The invention comprises placing a first Bind Work Queue Element (WQE) at the head of a work queue, wherein the first Bind WQE defines parameters associated with a first Memory Window. A set of Work Requests is then placed on the work queue, behind the first Bind WQE wherein the work requests invoke operations that access the first Memory Window. A second Bind WQE is then placed on the work queue, behind the first set of Work Requests. This second Bind WQE defines parameters associated with a second Memory Window. A second set of Work Requests is placed on the work queue behind the second Bind WQE and invoke operations that access the second memory window. The Memory Windows can be associated with a common Memory Region and have different addresses and lengths or different access rights. In another embodiment, the first and second Memory Windows can be associated with different Memory Regions.
