Abstract
Methods and systems for a read ahead operation are provided. The method includes maintaining a data structure by an adapter to track whether data blocks associated with a logical unit number (LUN) have been written or modified; extracting a starting logical block address (LBA) for executing a read request for reading data stored using the LUN; generating a LBA range for a read ahead operation that is used to predict data that may be read subsequent to the read request; determining if blocks associated with the LBA range for the read ahead operation have been written or modified; only reading ahead the blocks associated with the LBA range, when the blocks have been written to or modified; and temporarily storing the read ahead data at a cache LUN maintained by the adapter.
