摘要： A virtualization switch virtualizes a data storage area provided by a server device and provides it to a server device with. This virtualization switch processes a priority control and a bandwidth control also on the output side to packets which make an access to a virtual volume and which have different demands for a QoS but identical IP headers according to a discrimination result of a TCP connection. Here, the TCP connection is discriminated by managing a TCP source port on the side of the virtualization switch.

摘要： To provide a technique whereby a value of an error recovery level determined in negotiation processing between an initiator and a target can be set to a suitable value that is intended by a manager. A storage system comprises a storage section containing a target module that is connected to an initiator device; and a management section that manages the storage section. The target module carries out negotiation processing with the initiator device so as to determine a value of a first error recovery level. The first error recovery level is determined as the smaller of a value of a second error recovery level of the initiator device and a value of a third error recovery level of the target module. The management section carries out setting processing for allocating the initiator device that is to be connected to the target module to the target module, according to an instruction from a manager. In the setting processing, the value of third error recovery level is notified to the manager.

摘要： A storage system is provided which is capable of realizing a remote copy function for speeding up lines virtually by satisfying such demand to distribute copy data into a plurality of lines. In a storage system for connecting a local storage device and a remote storage device via a plurality of lines, the local storage device includes a remote copy program for distributing data of a plurality of logical volumes accessed from a host computer into a plurality of paths on the basis of status of the plurality of paths interposing the plurality of lines, to perform a remote copy from the local storage device to the remote storage device. Accordingly, the local storage device distributes data of the logical volumes into the plurality of lines to copy the data to the remote storage device, resulting in speeding up the lines virtually.

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.
摘要翻译：本发明的存储系统能够在保持主机和存储器之间的会话的同时更新秘密。管理员为主机和存储设置一个新的秘密。会话管理器向存储发出请求以打开使用新秘密的会话。会话管理器打开一个使用新密钥认证的会话。在秘密更新之前发出的对旧命令的响应通过使用旧秘密的会话从存储器发送到主机。秘密更新之后的新命令通过使用新秘密的会话从主机传输到存储。当所有旧的命令处理完成时，旧的秘密使用会话被关闭。
