Abstract
During a restart process in which metadata is loaded from at least one of a plurality of storage devices into a cache, a storage controller is configured to generate an IO thread in response to the receipt of an IO request, identify at least one metadata page of the metadata that is used to fulfill the IO request, and generate a loading thread in association with the received IO thread that is configured to cause the storage controller to perform prioritized loading of the identified at least one page of the metadata into the cache. The loading thread is detachable from the IO thread such that, in response to an expiration of the IO thread, the loading thread continues to cause the storage controller to perform the prioritized loading until the loading of the at least one page of the metadata into the cache is complete.
