Abstract
Techniques are disclosed for performing input/output (I/O) requests to two or more physical adapters in parallel. One method for performing an input/output (I/O) request includes mapping an address for at least a first page associated with a virtual I/O request to an entry in a virtual TCE table and identifying a plurality of physical adapters required to service the virtual I/O request. For each of the identified physical adapters, the entry in the virtual TCE table is mapped to an entry in a physical TCE table corresponding to the physical adapter. This method may also include, in parallel, issuing physical I/O requests to the physical adapters.
