摘要： The amount of data of presence information delivered from a presence server to a terminal is reduced by letting the presence server discard part of the presence information depending on communication measures and data type available to the terminal, by which the amount of data processed by the terminal is reduced. The presence server fetches terminal information stored therein based on terminal information contained in a presence inquiry request message from a user and thereby learns the type of data that can be processed by the terminal of the user. The presence server reconstructs the presence information of a referred user into information that can be processed by the terminal, and sends the information to the application of the terminal. By reducing the amount of presence data transmitted from the presence server to the terminal, the amount of data to be processed by the terminal can be cut down.

摘要： In the process of controlling a plurality of storage devices 190 in any one of a normal mode and a plurality of power-saving modes (such as standby and LRPM), a controller 110 selects the storage devices whose mode should be shifted from the normal mode to any of the power-saving modes; and before shifting to control of the selected storage devices in any of the power-saving modes, the controller calculates time and electric power required to make the selected storage devices return from each power-saving mode to the normal mode; and based on each calculated value, the controller sets a combination of power-saving modes and the number of storage devices that satisfy the return conditions defined by the host timeout period and the supplied power; and then, the controller controls the selected number of storage devices in the set combination of power-saving modes.

摘要： The storage control device of the present invention suppresses a drop in the performance of a host and storage control device by preventing the execution of encryption processing in the host and storage control device. The user presets an attribute that relates to the encryption of each storage device by considering the type of data transmitted from a higher order device (encryption data or plain data, for example) and the importance of the data and so forth. Such user operating policies are registered in a configuration management section via a setting section. When the data received from the higher-level device are encryption data, the storage control device stores the data in the storage device as is without performing encryption processing. When the received data are plain data, the storage control device converts the plain data into encryption data by performing encryption processing and stores the encryption data in the storage device.
