Abstract
Provided are a method, system, and program for handling Input/Output (I/O) requests. A bus enables communication with an initiator, target device and device controller, wherein the device controller accesses the target device to execute I/O commands directed to the target device. An I/O request command is received to access the target device. The initiator is configured to transmit at least one data request on the bus to one memory address in a predefined address window of the device controller. The device controller is enabled to claim the data request to the memory address in the predefined address window from the initiator on the bus to execute the data request against the target device.
