Reducing a rate at which requests are sent from one processor to another to reduce processor utilization at the processor receiving the requests

A system for managing Input/Output requests to a storage, comprising:

• a first processor;
• and
• a second processor;
• wherein the first processor performs:
• determining whether processor utilization at the first processor exceeds a utilization threshold;
• determining whether a specified operation is in progress in response to determining that the processor utilization at the first processor exceeds the utilization threshold;
• and
• sending, by the first processor, a message to the second processor to cause the second processor to reduce a rate at which requests are transferred from the second processor to the first processor in response to determining that the specified operations is in progress.

A method for managing Input/Output requests at a first processor from a second processor, comprising:

• determining whether a specified operation is in progress in response to determining that the processor utilization at the first processor exceeds the utilization threshold;
• and
• sending, by the first processor, a message to the second processor to cause the second processor to reduce a rate at which requests are transferred from the second processor to the first processor in response to determining that the specified operations is in progress.
