Computer system and its renewal method

A proximity detection unit detects the proximity of a finger to a screen and outputs a proximity detection signal. A contact detection unit detects the contact of the finger to the screen and outputs a contact detection signal. On the basis of the proximity detection signal, a display control unit magnifies and displays a predetermined range around a proximity corresponding position. On the basis of the contact detection signal depending on the contact operation of the indicator for the predetermined range, the display control unit fixes the magnified display of the predetermined range and does not change the display position of the magnified predetermined range depending on the movement operation of the finger on the screen.

A storage system has a plurality of flash packages, and a storage controller for receiving a write request from a host and sending a write-data write request based on data conforming to this write request to a write-destination flash package. A virtual capacity, which is larger than the physical capacity of the flash package, is defined in the storage controller. The storage system compresses the write data, and writes the compressed write data to the write-destination flash chip.

If a monitor measurement cycle is set as a long cycle, promotion in a short cycle cannot be performed; and even if the number of I/Os is very large in response to fluctuations of the number of I/Os in several minutes to several hours of normal work, pages will be promoted after waiting for several weeks. As a result, I/Os which could have normally accepted by an upper tier will be accepted by a lower tier, which results in a problem of worsening the performance efficiency. A monitoring system capable of preventing demotion due to temporary reduction of the number of I/Os for specific pages from a viewpoint of a long cycle and enabling prompt promotion in response to an increase of the number of U/Os for 3 the specific pages is realized. A load index value defined from a viewpoint of a long cycle and a load index value defined from a viewpoint of a short cycle are updated based on the number of I/Os which is counted cyclically for each storage area. Promotion and demotion are implemented based on a value(s) calculated from these load index values.
