摘要： α-Alumina powder having a purity of at least 99.99% by weight, a specific surface area of from 0.1 to 2.0 m2/g, a relative density of from 55 to 90%, and a closed porosity of 4% or less, wherein in a weight-based particle size distribution obtained by the dry sieving test according to JIS K0069 (1992), an amount of particles having a particle size of less than 75 μm is 5% by weight or less; an amount of particles having a particle size exceeding 2.8 mm is 15% by weight or less; and at least one frequency maximum peak appears in a particle size range of 100 μm or more and to less than 850 μm. This α-alumina powder can be charged in a crucible at a high bulk density, from which sapphire having a few voids can be produced without causing the oxidation of a crucible in a heat melting step.

摘要： When a public line is used for a remote copy function of storage in a disaster recovery (DR) system, the online performance is degraded due to the increase and decrease of the line utilization rate. Therefore, it is desired to change the remote copy function depending on the line utilization rate. Also, there is the possibility of data loss if disaster occurs during the copy between storage devices. Therefore, it is desired to perform the processing to detect the data status immediately before the occurrence of the disaster. By switching the synchronous transmission and the asynchronous transmission in accordance with the increase and decrease of the response time of the remote copy function between storage devices, the online performance of the primary site can be maintained without being influenced by the line utilization rate, and the data loss can be detected based on the used remote copy function.

摘要： In a storage device, a method is provided for preventing the risk of data loss and a significant decrease of writing speed due to area shrinkage when erased erase blocks have become fewer. A process of allocating a new page includes determining whether the length of a deallocated pages list is longer than n pages. If the list length is longer, one page is allocated from the deallocated pages list. If the list length is shorter, a capacity shortage error returns. Deleting a file using an erased pages list includes determining whether a page to be processed is emptied by deleting the file. If not so, the file is deleted from the page. If so, the contents of the last page-a in occupied pages are copied to the page, the page-a is written with data for erasure, and any erase block included in the page-a is made erasable.

摘要： A technology for verifying backup data capable of synchronizing timings of checksum calculation and verifying data consistency regardless of the storing position of the data is provided. In a backup system using a data update log, a checksum of data of a backup source and a checksum of backup data are checked, thereby verifying data consistency. Data check log generation means and the like are provided so that the data update log and the data check log are transmitted in order to a secondary site. By this means, the timings of the checksum calculation are synchronized. Further, by providing data area extraction means and the like, the verification of data consistency can be performed regardless of the storing position of the data.

摘要： A shared-nothing database management system employs a method of adding and removing a database server without significantly affecting the processing performance for accessing a table from a user or an application. A scheduler module creates a schedule which separately handles the addition of a CPU resource and the addition of a storage I/O resource, and a server is added in accordance with the created schedule. A common disk is used to remove a disk at an arbitrary timing. Further, a data region is previously subdivided on the common disk to eliminate a movement of data associated with the addition of a server.
