Abstract:
This invention relates to a method, system and computer program product for reading data from a storage controller in storage area network. A read data instruction is received from an application requesting data from the storage controller using a primary data path. If the data on the primary data path is not transferred in a defined time interval using the primary data path, data is requested from the storage controller using one or more alternative data paths. Data is received from the storage controller on one of data paths and into a buffer. When the read instruction has completed and that the data is in the buffer, the application is notified. Each data path is associated with a buffer and the data is received into a buffer associated with the path. The application is informed which buffer holds the data and the application accesses the data from this buffer.
