Abstract
A system and method integrates a persistent reply cache with operation of a file system executing on a storage system. In an illustrative embodiment, the persistent reply cache is embodied as a file comprising a combination of contents of (i) one or more enhanced non-volatile log records of non-volatile electronic storage, (ii) 'dirty' in-core buffer cache data structures, and (iii) on-disk data structures corresponding to those dirty buffer cache data structures. Integration is achieved through atomic operation of the reply cache with the file system to store information associated with a reply, e.g., to a client request, on electronic storage implemented as in-core buffer cache memory of the storage system, as well as on magnetic storage implemented as disks of the system.
