摘要： In a storage system, using a pool of encryption processing cores, the encryption processing cores are assigned to process either encryption operations, decryption operations, and decryption and encryption operations, that are scheduled for processing. A maximum number of the encryption processing cores are set for processing only the decryption operations, thereby lowering a decryption latency. A minimal number of the encryption processing cores are allocated for processing the encryption operations, thereby increasing encryption latency. Upon reaching a throughput limit for the encryption operations that causes the minimal number of the plurality of encryption processing cores to reach a busy status, the minimal number of the plurality of encryption processing cores for processing the encryption operations is increased.
