摘要： In a disk array system composed of a disk controller connected to a host system and a maintenance terminal and a disk array connected to the disk controller via a disk channel, when failure occurs in a drive in the disk array, the disk controller writes data stored in a plurality of disk drives on a faulty board on which a faulty drive is mounted into substitution disk drives and informs the maintenance terminal that the faulty board is replaceable after the reorganization of logical groups is completed.

摘要： Embodiments of the invention achieve data write in an appending manner by conversion from a logical block address to a physical block address in a HDD that has only one storage device and does not have a large-scale cache memory. In one embodiment, a check is made as to whether or not the size of an address translation table in a cache memory exceeds a threshold value. If the size exceeds the threshold value, entries whose number is specified are selected by the LRU method. The selected entries are added to a WRITE buffer, and the address translation table is saved on the HDD by executing WRITE. Seek time of a head at the time of WRITE is reduced, thereby improving WRITE performance. There is produced an effect of building such a snapshot that while a usual access to a HDD volume is allowed, it is possible to make an access to a volume of the snapshot which is a past state of the HDD. Disabling write after writing to the HDD is disabled. Thus, it possible to roll back to a HDD state at an arbitrary point of time.
摘要翻译：本发明的实施例通过从仅具有一个存储设备并且不具有大规模高速缓冲存储器的HDD中的逻辑块地址到物理块地址的转换，以附加的方式实现数据写入。在一个实施例中，对高速缓冲存储器中的地址转换表的大小是否超过阈值进行检查。如果大小超过阈值，则通过LRU方法选择号码指定的条目。所选择的条目被添加到WRITE缓冲区，并通过执行WRITE将地址转换表保存在HDD上。在WRITE时寻求头脑的时间减少，从而提高WRITE性能。产生了构建这样的快照的效果，即当允许对HDD卷的通常访问时，可以访问作为HDD的过去状态的快照的卷。写入HDD后禁止写入被禁用。因此，可以在任意时间点回滚到HDD状态。

摘要： Embodiments in accordance with the present invention relate to methods wherein a capacity of a disk drive is increased by partially overwriting adjacent tracks to shorten the track width and collectively updating a data update unit made up of a plurality of tracks, wherein the capacity reduction caused by a defective track is suppressed. Track groups having two types of track widths, or Shingled Tracks(ST) and Tiled Tracks(TT), are allocated in a zone. First, the zone is divided into two areas, namely, a shingled track (ST) area and a spare or tiled track (TT) area. When a defective track is detected in the shingled track (ST) area, it is checked whether or not the spare or tiled track (TT) area affords an area to be transferred. If it does, an area is transferred from the spare or tiled track (TT) area to the shingled track (ST) area. When it is confirmed that the allocation of ST has been completed, TT is allocated to the remaining spare or tiled track (TT) area in subsequent steps.

摘要： In the multiple access storage system, when there is a data access request designated by a data frame transmitted from a host computer to a storage blade SB#0 through a network for data, the data frame is transferred to SB#2 having possibility of presence of data corresponding to the data access request if the data is not found in SB#0. If the data is not found in SB#2 either and the number of transmission times of the data frame between SBs as counted in the data frame is not smaller than the threshold of the number of transmission times set as an equal value in each SB, SB#2 broadcasts the data frame to all SBs having possibility of presence of the data. If the number of transmission times is smaller than the threshold, SB#2 transfers the data frame to another SB having possibility of presence of the data.

摘要： Information update technique where information held by every apparatus does not need to be updated at the same time.A first server is connected with a second server. The first server judges whether it is possible to access the second server. When a result of the judgment shows that the second server may be accessed, then the first server sends an information update request including information to the second server. On the other hand, when the result of the judgment shows that it is impossible to access the second server, the first server repeats the judgment until it becomes possible to access the second server. When it becomes possible to access the second server, the first server sends an information update request including the information to the second server. Receiving the information update request, the second server updates its information by replacing the information with new information, i.e. the information included in the information update request.

摘要： To acquire contents prior to a distribution request from a client in a time zone having sufficient network bandwidth, and efficiently use network bandwidth. An access trends analysis handler analyzes access to contents by a client, a contents prediction handler predicts contents expected to be in demand in the future based on this analysis result, and a contents acquisition handler acquires the forecast contents in a time zone when there is sufficient network bandwidth. A contents deletion handler predicts contents in the acquired contents for which not much demand is expected from the client contents access trends, and deletes these contents. Due to this invention, a contents distribution apparatus can be provided which enables efficient use of network bandwidth and disk capacity.
