Abstract: In performing the issuance of a license key to a user through a selling agent or the like on line, the issuance of the license key is performed from a manufacturer to the selling agent or the like in such a manner that information which the selling agent or the like wants to keep in secret is prevented from being transmitted to the manufacturer. Further, when a deadline of a trial period by a trial license key is coming very close, a special license key which extends the deadline of the trial period is issued. In operation, the sales computer receives client information, a product number and a license program name inputted by a purchaser computer and transfers such information from which the client information is eliminated to the license-issuing computer. The license-issuing computer issues the license key when the authentication of the product number is normally finished. Further, the present invention provides a trial license key to a user.

Abstract: The write data is entered from the upper unit into a nonvolatile cache provided in a controller inside of each disk unit through a channel adaptor, a cache shared by each disk, and a disk adaptor. The data from the cache is compressed by the data compressing and restoring device and is written in the disk. At a time, the management information for compressed data is written in the cache and the disk as well. In case of breaking the management information of the cache when a failure takes place in the cache memory, the management information is written for each disk. Hence, the breakage does not have an adverse effect on the other disks. If the management information of the cache is broken, the management information given into the disk may be replaced with the broken information.

Abstract: A semiconductor storage device transfers data with an information processing device and includes a non-volatile semiconductor memory in which data is electrically re-writable, a volatile semiconductor memory connected to the non-volatile memory and temporarily storing data of the non-volatile semiconductor memory, and a CPU connected to the volatile semiconductor memory and the non-volatile semiconductor memory. The CPU controls the transfer of data among the non-volatile memory, the volatile memory and the CPU. The CPU also transfers data with the information processing device in accordance with a fixed-length form for data. When an access from the CPU to the volatile semiconductor makes a miss hit (i.e., misses), the CPU accesses the non-volatile semiconductor memory. When a failure is generated in the non-volatile semiconductor memory or when a predicted service life of the non-volatile semiconductor memory is elapsed, the non-volatile semiconductor memory can be substituted by an alternate memory.

Abstract: A semiconductor storage device is connected to at least one magnetic storage device. The input and output of data is made between the semiconductor storage device and an information processing device.
