Abstract:
Systems and methods described herein synchronize events between various components of storage device during the processing of an exception (i.e., an internal error). The storage device can have a plurality of processors which may each coordinate operations on various domains of storage device processing tasks. An exception occurring in one domain may require input and coordination from other domains within the storage device. Each exception may have a list of predetermined steps needed for completion which are coordinated via a series of sync points placed between exception action clusters which perform a series of specific operations until data or processing from another domain is needed to continue processing. The sync points can be utilized to halt processing in one domain until the other domains are in sync and complete one or more exception action operations. In this way, a streamlined and predictable synchronization between domains may occur during an exception.
