Abstract
A method, apparatus, and system for handling a failure of a hardware cryptography/compression accelerator is disclosed. The operations comprise: detecting that a hardware cryptography/compression accelerator at a first data storage system has failed; determining one or more failed cryptography and/or compression operation tasks that were submitted to the hardware cryptography/compression accelerator but were not completed due to the failure of the hardware cryptography/compression accelerator; and performing a remedial operation in response to the hardware cryptography/compression accelerator failure to prevent a systemic failure.
