    • Data is migrated from an original host storage system to another replacement host storage system with minimal client impact on a network. An original host storage system is connected directly to the replacement host storage system which is in turn connected to the network. Data migration occurs while allowing a client to access data in the original host storage system. When access is requested, the replacement host storage system determines if it resides locally or in the original host storage system. Depending on where the data resides, either the replacement host storage system acts on it or obtains it from the original host storage system.
    • 数据从原始主机存储系统迁移到另一个替代主机存储系统,对网络的影响最小。 原始主机存储系统直接连接到替代主机存储系统,替代主机存储系统又连接到网络。 数据迁移发生在允许客户端访问原始主机存储系统中的数据时。 当请求访问时,替换主机存储系统确定它是驻留在本地还是驻留在原始主机存储系统中。 取决于数据所在的位置,替换主机存储系统作用于其上或从原始主机存储系统获取。

    • Some embodiments are directed to replicating a content unit stored in a first storage environment comprising a first plurality of storage clusters to a second storage environment comprising a second plurality of storage clusters. The first storage environment may employ a replication policy, instituted at a first time, that specifies to which one of the second plurality of storage clusters content units stored in the first storage environment are to be replicated. The creation time of the first content unit may be determined and it may be determined when the creation time is before the time at which the first storage environment instituted the replication policy. If the creation time is not before the first time, one of the second plurality of storage clusters may be selected to which to replicate the first content unit based on the replication policy, and the content unit may be replicated to the selected one of the second plurality of storage clusters.
    • 一些实施例旨在将存储在包括第一多个存储集群的第一存储环境中的内容单元复制到包括第二多个存储集群的第二存储环境。 第一存储环境可以采用指定第一存储环境中存储的第二多个存储集群内容单元中哪一个将被复制的第一次建立的复制策略。 可以确定第一内容单元的创建时间,并且可以确定创建时间何时在第一存储环境设置复制策略的时间之前。 如果创建时间不是在第一次之前,则可以基于复制策略来选择第二多个存储集群中的一个来复制第一内容单元,并且内容单元可以被复制到第二个 多个存储集群。
