Abstract

See full text

In an embodiment, an average busy-to-success ratio is calculated for partitions that submitted operations to a shared resource during a first time period. A first busy-to-success ratio for a first partition during the first time period is calculated. If the first busy-to-success ratio is greater than the average busy-to-success ratio and a difference between the first busy-to-success ratio and the average busy-to-success ratio is greater than a threshold amount, a throttle amount for the first partition is increased. A first operation from the first partition during a first time subdivision of a second time period is received. If a number of operations received from the first partition during the first time subdivision of the second time period is greater than the throttle amount for the first partition, a busy indication is returned to the first partition and the first operation is not submitted to the shared resource.
