摘要： A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.

摘要： The present invention provides a method that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. Specifically, a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control out of user space I/O operations is provided. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device. Entries include access control values which identify whether the entry is valid and what access type operations may be performed on a corresponding portion of a storage device. I/O requests may be checked against these access control values to determine if an application instance that submitted the I/O requests may access the LBAs identified in the I/O requests in the manner requested.

摘要： A method, computer program product, and distributed data processing system for memory management. Memory regions are registered and have access rights and Protection domains associated with them in response to receiving a request for a memory operation including a virtual address, which is used to address into a data structure. A second data structure is then used to translate the virtual address into physical addresses for the operation. A third data structure is used to allow an incoming request responsive to a remote operation being initiated.

摘要： The present invention is a method and system for improving resource utilization in a connection management system. The present invention alleviates the resource contention and resource under-utilization problems, and avoids the problem of contamination from the late arrival of delayed packets to a new connection which utilizes the same resources used in a preview connection. The method includes transferring data by using the connection resources from the server; determining if an error occurred during the transfer of data; if an error is not detected, returning the connection resources to the server; and if an error is detected, indicating the existence of the error with a status bit and waiting a predetermined period of time prior to returning the connection resources to the server.

摘要： A fencing system for a small systems computer interface (SCSI) bus based multiprocessor system having a first processor, a second processor, a peripheral device and a SCSI bus for connecting the first and the second processors to the peripheral device. The inventive fencing system is connected to the SCSI bus and includes a system controller for generating a fencing signal and a device address. A fence control circuit is included for receiving the fencing signal and the device address and for disabling communication between the first processor and the peripheral device in response thereto. In a particular embodiment, a differential driver and receiver are provided on each line of the SCSI bus. The fencing system disables each driver and receiver for the processor to be fenced effectively isolating it from the peripheral device or its controller. Hence, the invention provides a system and technique for fencing nonproprietary i.e., SCSI based clusters of processors.
