摘要： A method includes segmenting a virtual volume into an active area configured to map to a first type of storage and a non-active area configured to map to a second type of storage through a storage virtualization engine. The second type of storage includes data associated with a host device and the first type of storage includes point-in-time images corresponding to the data associated with the host device. The first type of storage offers a higher performance than that of the second type of storage. The method also includes allocating a portion of space in the first type of storage to serve as a cache memory during a write operation and/or a read operation, and reducing a latency associated with the response to a write request and/or a read request through performing the corresponding write operation and/or the read operation through the first type of storage.
摘要翻译：一种方法包括将虚拟卷分割成被配置为映射到第一类型的存储的活动区域和被配置为通过存储虚拟化引擎映射到第二类型存储的非活动区域。第二类型的存储器包括与主机设备相关联的数据，并且第一类型的存储器包括对应于与主机设备相关联的数据的时间点图像。第一种类型的存储提供比第二种类型的存储更高的性能。该方法还包括在写入操作和/或读取操作期间分配第一类型的存储器中的空间的一部分用作高速缓冲存储器，并且减少与对写入请求和/或读取请求的响应相关联的等待时间通过第一类型的存储执行相应的写入操作和/或读取操作。
