Abstract

System and methods for selectively or automatically migrating resources between storage operation cells are provided. In accordance with one aspect of the invention, a management component within the storage operation system may monitor system operation and migrate components from storage operation cell to another to facilitate failover recovery, promote load balancing within the system and improve overall system performance as further described herein. Another aspect of the invention may involve performing certain predictive analyses on system operation to reveal trends and tendencies within the system. Such information may be used as the basis for potentially migrating components from one storage operation cell to another to improve system performance and reduce or eliminate resource exhaustion or congestion conditions.

Claims

1. A storage system that automatically transfers a storage resource from a first storage operation cell to a second storage operation cell, the storage system comprising:

monitoring a first operational characteristic of a first storage resource in the first storage operation cell wherein the first operational characteristic has an associated first threshold;

identifying a second storage operation cell including a second storage resource having a second operational characteristic that does not exceed a second threshold;

determining whether the first storage resource may be transferred to the second storage operation cell such that the transfer is capable of causing the first operational characteristic to remain within the first threshold; and

automatically transferring the first storage resource to the second storage operation cell if the first operational characteristic is near or exceeds the first threshold;

wherein the identifying includes creating the second storage operation cell.
