    • A method for initializing a memory area, the method includes: receiving a request to access a first memory sub area of a first memory area that comprises multiple memory sub areas; and initializing the first memory sub area if a first memory area initialization indicator differs from a first memory sub area initialization request indicator; wherein the first memory area initialization request indicator is a multiple bit variable indicative of a time of a last request to initialize the first memory area and the first memory sub area initialization indicator is a multiple bit variable indicative of a time of a request to initialize the first memory area that resulted in a last initialization of the first memory sub area.
    • 一种用于初始化存储区域的方法,所述方法包括:接收访问包括多个存储器子区域的第一存储器区域的第一存储器子区域的请求; 以及如果第一存储区初始化指示符与第一存储器子区初始化请求指示符不同,则初始化第一存储器子区; 其中所述第一存储区初始化请求指示符是指示初始化所述第一存储器区域的最后请求的时间的多位变量,并且所述第一存储器子区初始化指示符是表示初始化所述第一存储区初始化请求的时间的多位变量 导致第一存储器子区域的最后初始化的第一存储区域。

    • A method for synchronizing data storage systems is provided. The method comprises designating a relationship between a first data storage system and a second data storage system, such that data stored in the first data storage system is copied to the second data storage system, in response to determining that the data stored in the first data storage system has been modified; receiving a first request to modify data stored in a first data block of a first storage volume in the first data storage system, wherein the data block is modified according to the first request; determining that the first data block has not been successfully synchronized when the modified data stored in the first data block is not copied to the second data storage system; and executing a process to retry synchronization of the first data block until synchronization of the first data block is successful, without suspending the relationship while the process is executed.
    • 提供了一种同步数据存储系统的方法。 该方法包括:指定第一数据存储系统和第二数据存储系统之间的关系,使得存储在第一数据存储系统中的数据被复制到第二数据存储系统,以响应于确定存储在第一数据中的数据 存储系统已经修改; 接收修改存储在第一数据存储系统中的第一存储卷的第一数据块中的数据的第一请求,其中根据第一请求修改数据块; 当存储在第一数据块中的修改数据未被复制到第二数据存储系统时,确定第一数据块尚未成功同步; 以及执行重试所述第一数据块的同步的处理,直到所述第一数据块的同步成功,而不执行所述处理时暂停所述关系。
