Abstract
A method and system for optimizing input-output requests. Input-output requests are intercepted before any information transfers to a data storage facility. Commands in the input-output request are scanned to determine their starting and ending addresses. The scanned addresses are then converted into an address extent that is coextensive with all the starting and ending addresses associated with commands for transferring data to the data storage facility. That address extent is transferred to the data storage facility and may incorporate fewer addresses than are present in an initial address extent.
