摘要： A storage system encrypts plain text from an external device and stores the cryptogram into a disk unit, decrypts stored data in the disk unit and transmits decrypted text to the external device. The plain and decrypted text must be in agreement when seen from the external device. If a failure occurs in the encrypting or decrypting process, the plain and decrypted text disagree. The storage system includes an encryption unit for encrypting first data, a decryption unit for decrypting the encrypted data into second data, and a comparison unit for comparing the first and second data. When the first and second data do not agree, the first data is encrypted by a different encryption unit and the encrypted data is decrypted into third data, whereupon the first and third data are compared. When the first and third data do not agree, a failure report is sent.
摘要翻译：存储系统从外部设备加密纯文本，并将密码存储到磁盘单元中，对存储在磁盘单元中的数据进行解密，并将解密的文本发送到外部设备。从外部设备看时，明文和解密的文本必须一致。如果在加密或解密过程中发生故障，则明文和解密的文本不同意。存储系统包括用于加密第一数据的加密单元，用于将加密数据解密为第二数据的解密单元，以及用于比较第一和第二数据的比较单元。当第一和第二数据不一致时，第一数据被不同的加密单元加密，并且加密的数据被解密成第三数据，于是比较第一和第三数据。当第一和第三个数据不一致时，发送故障报告。

摘要： During iSCSI communication, according to the contents of commands issued by a host computer, the command response time is increased due to the influence of the TCP Delayed ACK. Thus, a command issued by the host computer is analyzed, the number of TCP/IP packets required for transmitting the data requested by this command is calculated, and a precedence packet is transmitted, so that no influence is experienced due to the Delayed ACK.
