1. A method for correlating the execution throttle levels of the servers of a network to the command queue depth of the storage controllers in the network, each of the storage controllers managing one or more logical storage units, comprising the steps of:

  • identifying the servers of the network;

    identifying the logical ownership of each logical storage unit on the network;

    verifying that a rule governing the command throughput of the servers and storage controllers of the network is satisfied, the rule defining a relation between the execution throttle levels of the servers of the network and command queue depth of the storage controllers of the network; and

    adjusting the execution throttle level of at least one server of the network in response to a determination that the rule was not satisfied.
