    • In accordance with one example, a method for comparing data units is disclosed comprising generating a first digest representing a first data unit stored in a first memory. A first encoded value is generated based, at least in part, on the first digest and a predetermined value. A second digest representing a second data unit stored in a second memory different from the first memory, is generated. A second encoded value is derived based, at least in part, on the second digest and the predetermined value. It is determined whether the first data unit and the second data unit are the same based, at least in part, on the first digest, the first predetermined value, the first encoded value, and the second digest, by first processor. If the second data unit is not the same as the first data unit, the first data unit is stored in the second memory.

    • The present invention relates to a trifunctional catalyst used in catalytic cracking device in petroleum refining industry and a method for preparing the same. The trifunctional catalyst of the invention comprises absorbent, cerium dioxide and vanadium pentoxide acting as oxidative catalyst and cerium oxyfluoride acting as structural promoter. The oxidative catalyst and structural promoter are dispersed over the absorbent. The absorbent is spinel-based composite oxides having a general formula of MgAl2-xFexO4.yMgO, where the x is 0.01-0.5 and y is 0.2-1.2. In the trifunctional catalyst, the raw material for forming the chemical compound containing rare-earth cerium is hamartite powder. The method for preparing the trifunctional catalyst of the invention is shown as follows: the components relating to the preparation of the finished product are dissolved or dispersed into liquid materials; then the trifunctional catalyst is obtained after the mixing, drying and calcining of such liquid materials. The trifunctional catalyst of the invention is used for highly efficient absorption and desorption of sulfoxides contained in the catalytic cracking flue gas regenerated in the process of petroleum refining, the combustion promoting of carbon monoxide and the reduction of nitrogen oxides. Furthermore, the method for preparing such trifunctional catalyst is featured for its lower cost.

    • Data is stored by utilizing a first operating mode and a second operating mode. In one embodiment, in the first operating mode, a continuous replication method is utilized to store data on a primary storage system and to generate a backup version of the data on a backup storage system. While data is being stored in accordance with the first operating mode, one or more activities performed by the data storage system(s) are monitored. As long as the monitored activity or activities display a first status, the first operating mode is maintained. If the monitored activity or activities display a change in status, the first operating mode is suspended, and data is stored pursuant to the second operating mode. In one embodiment, in the second operating mode, a delta replication method is utilized to store data on the primary storage system and to back up the data on the backup storage system.
    • 通过利用第一操作模式和第二操作模式来存储数据。 在一个实施例中,在第一操作模式中,使用连续复制方法来在主存储系统上存储数据,并在备份存储系统上生成数据的备份版本。 当根据第一操作模式存储数据时,监视由数据存储系统执行的一个或多个活动。 只要所监视的活动或活动显示第一状态,则维持第一操作模式。 如果监视的活动或活动显示状态的变化,则暂停第一操作模式,并且根据第二操作模式存储数据。 在一个实施例中,在第二操作模式中,使用增量复制方法来在主存储系统上存储数据并备份备份存储系统上的数据。

    • A method and system are provided for comparing data stored in a first storage system with corresponding data stored in a second storage system. In one implementation, the first system generates a random value associated with a respective data block P, and transmits to the second system an identifier associated with the data block P, and the random value. The second system generates a first digest representing a data block B, uses the first digest to encode the random value, producing a first encoded value, and transmits the first encoded value to the first system. The first system generates a second digest representing the data block P, uses the second digest to encode the random value, producing a second encoded value, and compares the first and second encoded values. If the two encoded values are equal, the data block B is a duplicate of the data block P. If the two encoded values are not the same, the data blocks are different. Additionally, a method is provided for synchronizing data stored on a second system to data stored on a first system. In one implementation, a data block P stored on a first system is compared to a data block B stored on a second system, as described above. If the two data blocks are different, the first system transmits a copy of the data block P, and the second system stores the copied data block P.
    • 提供了一种方法和系统,用于将存储在第一存储系统中的数据与存储在第二存储系统中的对应数据进行比较。 在一个实现中,第一系统生成与相应数据块P相关联的随机值,并向第二系统发送与数据块P相关联的标识符和随机值。 第二系统生成表示数据块B的第一摘要,使用第一摘要对随机值进行编码,产生第一编码值,并将第一编码值发送到第一系统。 第一系统生成表示数据块P的第二摘要,使用第二摘要对随机值进行编码,产生第二编码值,并比较第一和第二编码值。 如果两个编码值相等,则数据块B是数据块P的副本。如果两个编码值不相同,则数据块是不同的。 此外,提供了一种用于将存储在第二系统上的数据与存储在第一系统上的数据进行同步的方法。 在一个实现中,如上所述,将存储在第一系统上的数据块P与存储在第二系统上的数据块B进行比较。 如果两个数据块不同,则第一系统发送数据块P的副本,第二系统存储复制的数据块P.
