Abstract
A storage system communicates with a host in a session including one or more connections. The storage system includes a front-end interface, a processor, and a storage area. The storage area stores session management information for managing the session of the communication with the host. The front-end interface stores connection management information for managing the connection of the session. The front-end interface controls access from the host by referring to the connection management information.

A storage system that communicates with a host in a session including one or more connections, the storage system comprising:
- a front-end interface;
- a processor;
- and
- a storage area,
- wherein
- the storage area stores session management information for managing the session with the host,
- the front-end interface stores connection management information for managing the one or more connections of the session, and
- the front-end interface controls access from the host by referring to the connection management information,
- wherein, in termination of a connection of the one or more connections between the host and the front-end interface,
- the front-end interface acquires information of the session corresponding to the connection from the connection management information,
- the front-end interface transmits a disconnection completion notification to the host,
- the front-end interface designates the session and transmits a disconnection request for the connection to the processor, and
- the processor updates the session management information in response to the received disconnection request.
