Prioritization of interrupts in a storage controller based on interrupt control directives received from hosts

A method for deploying computing infrastructure, comprising integrating computer-readable code into a computer, wherein the code in combination with the computer is capable of performing:

• 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.

A method, comprising:

• sending, from a host, an interrupt control directive to a storage controller;
• sending, from the host, access requests for at least one at least one storage device coupled to the storage controller, wherein in response to the access requests the storage controller generates a first plurality of interrupts that indicates whether access to the at least one storage device is allowed to the host, wherein the storage controller generates 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 wherein the storage controller determines how many of the first plurality of interrupts and how many of the second plurality of interrupts to send to the host, based on the interrupt control directive;
• and
• receiving, at the host, those interrupts determined by the storage controller to send to the host, wherein the interrupt control directive sent by the host to the storage controller indicates 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.
