The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for data storage includes, in a system that includes multiple servers, multiple multi-queue storage devices and at least one storage controller that communicate over a network, storing data by the servers in a storage process that, (i) caches the data in a cache memory that is accessible to the servers and to the storage devices and, (ii) de-stages the cached data from the cache memory to the storage devices. A progress of the storage process is continually journaled, by the servers, in a plurality of server-specific journals residing in the cache memory. In response to a failure occurring during the storage process, the data is recovered by the storage controller based on the server-specific journals.”
The patent application was filed on February 6, 2017 (15/424,921).
