| Summary: | 1. Field of the Invention
Managing a cache memory includes using a first cache memory, copying data from the first cache memory to a second cache memory, and, following copying, using the second cache memory along with the first cache memory. Prior to using the second cache memory, data may be copied to the second cache memory in response to the data being provided from a disk storage area to the first cache memory. Copying data may include background copying the data during times when the cache memories are not otherwise being used. Using the second cache memory along with the first cache memory may include providing data from a disk storage area to a first cache memory, providing data from the disk storage area to a second cache memory, where the first and second cache memories contain at least some data that is different, and writing a portion of the data to both of the cache memories in response to the portion of data being modified while stored in the cache memories. |
