Abstract:
A method for processing a read sub-command in a secondary storage controller is disclosed. The method includes receiving the read sub-command from a primary storage controller; retrieving data in response to the read sub-command; utilizing a write request to write the retrieved data directly to a memory accessible by a host device; issuing an additional request to the same memory after the write request; receiving an indication of completion of the additional request; and reporting a sub-completion status to the primary storage controller.
