Abstract
An embodiment of the invention provides a method comprising: performing an application write; storing the application write in a local cache; performing a system call to request an underlying storage system to persist any application writes that are not yet persisted; and in response to the system call, copying the application write in the cache to a shared permanent storage. In another embodiment of the invention, an apparatus comprises: an application configured to perform an application write; a cache software configured to store the application write in a local cache; wherein the application is configured to perform a system call to request an underlying storage system to persist any application writes that are not yet persisted; and in response to the system call, the cache software is configured to copy the application write in the cache to a shared permanent storage.
