摘要： The present invention provides a method for guaranteeing a data consistency among a plurality of storages and sites, when data transfer is performed by asynchronous remote copying from a site including a plurality of storages.When writing is made into a first storage system or a second storage system, the storage system that received the writing transfers the write data to the other storage system within the site by synchronous remote copying. At this timing the first storage system gives the write data information for order assurance.Furthermore, the first or the second storage system transfers the write data and thus given information for order assurance to the third or the fourth storage system by asynchronous remote copying.Furthermore, the third or the fourth storage system which has received the write data transfers to the other storage system within the same site the write data and information for order assurance by synchronous remote copy.

摘要翻译： 本发明提供一种当从包括多个存储器的站点进行异步远程复制执行数据传输时，保证多个存储器和站点之间的数据一致性的方法。 当写入第一存储系统或第二存储系统时，接收到写入的存储系统通过同步远程复制将写入数据传送到站点内的其他存储系统。 在这个时刻，第一个存储系统给出写入数据信息以进行订单保证。 此外，第一或第二存储系统通过异步远程复制将写数据和由此给出的用于订单保证的信息传送到第三或第四存储系统。 此外，已经接收到写入数据的第三或第四存储系统通过同步远程复制传送到同一站点内的另一个存储系统的写入数据和用于命令保证的信息。

摘要： An embodiment of the invention provides a system and method for displaying the scheduling availability of a user. The system includes an occupancy module for analyzing the schedule of the user to determine the occupancy for a time period in the schedule. The time period includes an available time slot and/or an occupied time slot. A processor connected to the occupancy module determines whether the occupancy for the time period is above a threshold level of occupancy. The threshold level of occupancy includes a maximum number of occupied time slots, a maximum percentage of occupied time slots, a maximum amount of occupied time, and/or a maximum percentage of occupied time. A scheduling module connected to the processor automatically displays the scheduling availability of the user as unavailable for the time slot when the occupancy for the time period is above the threshold level of occupancy.
