Abstract: Methods and systems for configuring network storage are presented. A method for configuring network storage may include: detecting one more connection rates associated with one or more input PHYs associated with one or more parent devices; detecting a number of input connections associated with one or more PHYs associated with one or more parent devices; setting one or more connection rates associated with one or more input PHYs associated with one or more child devices according to the one or more connection rates associated with the one or more input PHYs associated with the one or more parent devices; and setting a number of input connections associated with one or more PHYs associated with one or more child devices according to a number of input connections associated with one or more PHYs associated with one or more parent devices.

Abstract: An apparatus and method for dynamically enabling and disabling interrupt coalescing in a data processing system. The present invention involves consistently monitoring IO load on an IOP of an IO adapter. The firmware on the IO adapter may have a global variable that stores counters for PCI function registers. Each counter tracks the number of outstanding IOs of a corresponding PCI function register. The counter is incremented whenever a new IO is received and is decremented upon posting the completed message back to the OS. A timer interrupt is generated periodically so that an ISR may be periodically performed. In the ISR, the maximum value stored of each counter seen since last timer interrupt is analyzed. When the maximum value stored is greater than a predetermined threshold value, the interrupt coalescing is enabled.
