LATENCY REDUCTION ASSOCIATED WITH A RESPONSE TO A REQUEST IN A STORAGE SYSTEM |
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. |
