Summary:A method of data management in a data storage apparatus includes determining that a memory region (MR) stored in a first storage tier is suitable for hibernation. A tier-down operation is executed to move the MR to a second storage tier. In response to a remote direct memory access (RDMA) request to the MR from a client, a notification response is sent to the client to notify the client of the hibernated status of the MR. Moreover, in response to receiving a remote procedure call (RPC), from the client, the requested memory access is provided to the client. The requested memory access is provided to the client without any additional round-trip times (RTTs).
