Title:
APPARATUS, SYSTEM, AND METHOD FOR DESTAGING CACHED DATA
Document Type and Number:
WIPO Patent Application WO/2012/100257
Kind Code:
A3
Abstract:
An apparatus, system, and method are disclosed for destaging cached data. A cache controller (116) detects one or more write requests to store data in a backing store (118). The cache controller (116) sends the write requests to a storage controller (104) for a nonvolatile solid-state storage device (102). The storage controller (104) receives the write requests and caches the data in the storage device (102) by appending the data to a log (940) of the storage device (102). The log (940) includes a sequential, log-based structure preserved in the storage device (102). The cache controller (116) receives at least a portion of the data from the storage controller (104) in an order favoring operation of the storage device (102) and destages the data to the backing store (118) in that order, which is selected so that operation of the storage device (102) is more efficient in response to destaging.
