The present invention is an information system that includes: a first computer; a first storage apparatus; a first network apparatus, to which the first computer and the first storage apparatus are connected, providing a first fabric service; a second computer; a second storage apparatus; a second network apparatus, to which the second computer and the second storage apparatus are connected, providing a second fabric service; and a network that connects the first network apparatus and the second network apparatus, wherein the first computer accesses the first fabric service, the second computer accesses the second fabric service, and the first storage apparatus and the second storage apparatus access the first fabric service and the second fabric service, respectively.

Information system having computer and storage apparatus coupled to network

Since no access history is generated for when a file update which makes use of a copy and paste function is performed, it is difficult to detect the file that served as the reference source during the update. Hence, the present invention is provided to manage a client access history for each file that is stored in a storage device, and detect a file, which has been accessed between a time when a corresponding user logs into the storage device and a time when an updated file is updated based on information of the access history, as the reference source for the updated file.

File detection device and method

A management device connected to a file server providing a computer with file data stored in a storage subsystem, and collects information about access to the file data. In the management device, a log of access to the file data stored in the storage subsystem is collected as access data, and the access data for the same file data is grouped. With such a configuration, a large amount of information about access to the file data can be easily used, and the amount of information can be compressed.

Management device and computer system

A network system including a management device with both a status managing unit for collecting status information on a terminal status and a terminal instructing unit for transmitting a shift start message to the terminal to make transfer data to the server on the basis of the status information collected by the status managing unit. The terminal includes a determining unit for determining data transfer in response to the shift start message, a data transferring unit for transferring the data to the server when the determining unit determines the data transfer, a storage device control unit for erasing the data from a storage device after completion of data transfer, and a thin client shifting unit for causing the terminal to function as a thin client after erasure of data.

Network system

A management system accepts a connection request from a client computer to a server computer, acquires connection settings information, calculates a network bandwidth required for processing for connection from the client computer to the server computer, stores the connection request into a connection request processing queue, determines whether the processing for the connection from the client computer to the server computer can be performed or not, and notifies the client computer of a server identification number. The client computer issues a connection request to the server computer based on the received server identification number, and starts communication therewith. In spite of concentration of connection requests from a large number of client computers to server computers, the connection requests can be processed while controlling the communication data volume generated in a network at a point where the server computers are aggregated, so as to avoid occurrence of congestion.

Communication system and communication management method

Provided is an information system for preserving data of a storage device in a computer that repeats the connection to and disconnection from a communication network. The computer acquires data to be written into the storage device and manages the update status of the storage device, transfers the data written into the storage device to the storage controller independent from the writing of data into the storage device when the computer is in a communicable state with the storage controller, and discontinues the transfer of data written into the storage device to the storage controller and manages the transfer status when the computer is not in a communicable state with the storage controller.

Information system and information storage method of information system

The invention enables the control of the information in a storage unit in a user terminal, prevents data from leaking to unauthorized users and protects information in the user terminal. A management OS manages the input/output to/from a user work OS in the user terminal, identifies a control-triggering condition set by a management server, controls the information in the storage unit storing the user work OS-related information so that information leakage can be prevented, and it also backs up the user work OS-related information to the storage apparatus using the user work OS input/output information.
