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.
摘要翻译：在iSCSI通信期间，根据主机发出的命令内容，由于TCP延迟ACK的影响，命令响应时间增加。因此，分析由主计算机发出的命令，计算发送由该命令请求的数据所需的TCP / IP分组的数量，并且发送优先分组，从而不会由于延迟ACK而产生影响。

摘要： In a situation where a host computer or storage system is an initiator and the storage system or another storage system is a target, when the initiator intends to check LUs in the target, if the initiator judges that the number of delay ACKs is set to more than one, it simultaneously issues the same number of check commands—SCSI Inquiry LUN#a and LUN#b—as the number of delayed ACKs, or check commands in multiples of the number of delayed ACK, to the target; and, when receiving check results—SCSI Data-In—in response to the check commands from the target, sends an acknowledgement to the target. Accordingly, when the number of delayed ACKs set in the TCP in the initiator is more than one, the initiator simultaneously issues check commands to the target designating the same number of LUs as the number of delayed ACKs, and the responses will not be influenced by the delayed ACK.
摘要翻译：在主计算机或存储系统是启动器并且存储系统或另一个存储系统是目标的情况下，当发起者打算检查目标中的LU时，如果发起者判断延迟ACK的数量被设置为更多一个，同时发出相同数量的检查命令 - SCSI查询LUN＃a和LUN＃b - 作为延迟ACK的数量，或者将延迟ACK的数量的倍数的检查命令发送到目标; 并且当接收到检查结果时 - 对来自目标的检查命令的SCSI数据输入响应向目标发送确认。因此，当发起方的TCP中设置的延迟ACK的数量多于一个时，发起者同时向目标发出指示与延迟ACK的数量相同数目的LU的检查命令，并且响应将不受延迟ACK。

摘要： The storage system of the present invention is able to update a secret while maintaining a session between a host and storage. The administrator configures a new secret for the host and the storage. The session manager issues a request to the storage to open a session that uses the new secret. The session manager opens a session that uses the new secret following authentication. A response to an old command issued prior to the secret update is transmitted from the storage to the host via a session that uses an old secret. A new command following the secret update is transmitted from the host to the storage via the session that uses the new secret. When all the old command processing is complete, the old secret using session is closed.
