摘要： In a disk array system, data read out and data written anew are temporarily held as former data in a former data holding portion. When a write operation has occurred, a CPU searches the holding portion for write data, it generates update data from the new and former write data items, and it holds the generated update data in an update data holding portion. In addition, the CPU stores the storage address of redundant data associated with the held update data, as log data in a log data holding portion. Further, the CPU operates asynchronously with the write operation to read out the redundant data of the address of the holding portion, to calculate new redundant data from the read redundant data and the held update data, and to write the new redundant data into the address of the log data. On this occasion, a parity area and a data area are separated so as to heighten read/write processing speeds and a parity generation processing speed.
摘要翻译：在磁盘阵列系统中，数据读出和重新写入的数据被暂时保持为前一数据保存部分中的前一数据。当发生写入操作时，CPU在保持部分中搜索写入数据，它从新的和先前的写入数据项生成更新数据，并且将生成的更新数据保存在更新数据保存部分中。此外，CPU将与所保持的更新数据相关联的冗余数据的存储地址作为日志数据存储在日志数据保持部分中。此外，CPU与写入操作异步地读出保持部分的地址的冗余数据，从读取的冗余数据和保持的更新数据计算新的冗余数据，并将新的冗余数据写入地址的日志数据。在这种情况下，分离奇偶校验区域和数据区域，以便提高读/写处理速度和奇偶校验生成处理速度。

摘要： An image coding apparatus includes a coding unit which generates coded data on a block basis, by coding the input image; a switching unit which selects and outputs either the coded data or uncompressed image data corresponding to the coded data; and a judging unit which judges, on a block basis, whether the code amount of the coded data is larger than a predetermined threshold. A control unit changes, to a predetermined specified coding type, the coding type of a first block and the coding type of a second block when the code amount of coded data generated by coding the first block is judged to be larger than the threshold, and the switching unit outputs the uncompressed image data corresponding to the coded data when the coding type of the coded data is the specified coding type.

摘要： Multiple storage systems have capability to provide thin provisioning volumes to host computers and capability to transfer (import/export) management information regarding thin provisioning between storage systems. Moreover, at least one of the storage systems posses capability to provide storage area of other storage system as own storage area virtually via connection to the other storage system (i.e. external storage). Target storage system achieves efficient migration and unifying storage resource pool by importing or referring the management information obtained from source storage system and by utilizing the source storage system as external storage. One implementation involves method and process for migration of thin provisioning volumes using chunks having same length between source storage system and destination storage system. In this implementation, storage resource pool is unified by importing management information from the source storage system, and automated page-based relocation is performed to adjust actual location of data.

摘要： A first storage system stores information relating to the updating of data stored in that system as a journal. More specifically, the journal is composed of a copy of data that was used for updating and update information such as a write command used during updating. Furthermore, the second storage system acquires the journal via a communication line between the first storage system and the second storage system. The second storage system holds a duplicate of the data held by the first storage system and updates the data corresponding to the data of the first storage system in the data update order of the first storage system by using the journal.

摘要： A method of utilizing storage in a storage system comprises prioritizing a plurality of storage areas in the storage system for data recovery with different priorities; and performing data recovery of the storage system at an occurrence of a failure involving one or more of the storage areas in the storage system based on the priorities. Data recovery for one storage area having a higher priority is to occur before data recovery for another storage area having a lower priority in the storage system. In various embodiments, the prioritization is achieved by monitoring the access characteristics, or the priority is specified by the host or management computer based on the usage and/or importance of data stored in the storage system, or the priority is determined by the storage system based on the area assignment/release (i.e., usage) of thin provisioned volumes.
