Abstract
Shielding a storage device of a storage system from one or more storage performance enhancement procedures (SPEPs) is disclosed. A SPEP can be regarded as a procedure that manipulates data stored via a storage device in a manner that attempts to improve performance of the storage system. As such, SPEPs are generally distinct from basic reading and writing of data that is not associated with storage system performance optimization. A SPEP can typically be effectively run without storage device performance degradation, however some conditions, such as very full drives, etc., can result in substantial storage device performance degradation where one or more SPEP is performed. As such, shielding can restrict permission to perform one or more SPEPs at a storage device expected to, or actually experiencing, a threshold level of performance degradation. Shielding is distinct from conventional techniques marking a drive as failed, failing, etc., as is disclosed herein.
