摘要：
Described are techniques for managing data in a data storage system. While the data storage system is operating in a first mode, portions of cached write data not yet destaged to a data storage device are copied from the volatile memory cache to a first area in a flash-based memory. In response to a vault operation event, the data storage system operates in a second mode in which all remaining portions of cached write data from the volatile memory cache not currently included in the first area are copied to a second area of the flash-based memory.
