Abstract:
1. A method, comprising: receiving, at a storage controller, an interrupt control directive from a host; generating, at the storage controller, a first plurality of interrupts, in response to access requests received from the host for at least one storage device coupled to the storage controller, wherein the first plurality of interrupts indicates whether access to the at least one storage device is allowed to the host; generating, at the storage controller, a second plurality of interrupts, wherein the second plurality of interrupts comprises unsolicited interrupts for the host that are different from the first plurality of interrupts; and controlling, at the storage controller, how many of the first plurality of interrupts and how many of the second plurality interrupts to send to the host, based on the received interrupt control directive, wherein a predetermined ratio of the first plurality of interrupts and the second plurality of interrupts that are to be sent to the host during a period of time is indicated in the received interrupt control directive.
