Abstract
Methods and systems for processing an input/output (I/O) requests are provided. The method includes generating an I/O request by an initiator adapter of a computing device that interfaces with a target adapter; indicating by the initiator adapter that the I/O request is sequential in nature. When the I/O request is a sequential read request, the target adapter notifies a target controller to read-ahead data associated with other sequential read requests; and stores the read ahead data at a cache such that data for the other sequential read requests is provided from the cache instead of a storage device managed by the target controller. A sequential write request is processed without claiming any cache space, when data for the write request is not to be accessed within a certain duration.
