摘要： A method for migrating files from a source server to a target server are disclosed. The method includes determining file property information for one or more data files on the source server. One or more data file entries are created in a file property table with the file property information for each data file. A data file entry is selected from the file property table. The file property information of the selected data file entry from the file property table is compared to the file property information of the corresponding data file stored in the source server to determine whether there is a match. In response to determining a mismatch, the data file in the source server is copied to the target server. The data file copied to the target server is verified to be the same as the data file of the source server.
摘要翻译：公开了一种从源服务器向目标服务器迁移文件的方法。该方法包括确定源服务器上的一个或多个数据文件的文件属性信息。在文件属性表中创建一个或多个数据文件条目，其中包含每个数据文件的文件属性信息。从文件属性表中选择一个数据文件条目。将来自文件属性表的所选数据文件条目的文件属性信息与存储在源服务器中的相应数据文件的文件属性信息进行比较，以确定是否存在匹配。响应于确定不匹配，源服务器中的数据文件被复制到目标服务器。复制到目标服务器的数据文件被验证为与源服务器的数据文件相同。

摘要： A system and method for reading files stored on a storage system is disclosed. The method includes communicatively coupling one or more remote systems for reading files stored in storage with a first set of files according to a predetermined data format and in a cache memory with a second set of files, the second set of files being a subset of the first set of files. Next one or more remote systems are received at least one read request for reading a sequence of files. A determination is made, among the files of the sequence of files, whether one or more cached files are already stored in the cache memory and whether one or more remaining files are not already stored in the cache memory. Creating, within the one or more remaining files, an order according to which the remaining files should be read on the storage system.
