Unused memory registrations in a remote memory system are proactively identified and freed. A memory server maintains a list of resource tracking entries for its outstanding memory registrations. The memory server continually monitors its list of resource tracking entities. When the memory server finds an unused memory registration in its list, it unregisters the corresponding shared memory region. The monitoring may be performed in the background of the memory server by, e.g., a monitor thread. As a result, unused memory registrations may be quickly released.

Memory registration for remote direct memory access

In some examples, a computer identifies a plurality of memory servers accessible by the computer to perform remote access over a network of data stored by the plurality of memory servers, sends allocation requests to allocate memory segments to place interleaved data of the computer across the plurality of memory servers, and receives, at the computer in response to the allocation requests, metadata relating to the memory segments at the plurality of memory servers, the metadata comprising addresses of the memory segments at the plurality of memory servers. The computer uses the metadata to access, by the computer, the interleaved data at the plurality of memory servers, the interleaved data comprising blocks of data distributed across the memory segments.

Client allocation of memory across memory servers

In some examples, a client system, in response to a request to modify a first data page at a memory server in a remote access by a client over a network, sends, to the memory server, a request to update a data modification tracking structure stored by the memory server to indicate that the first data page is modified. The client system initiates an incremental data backup from the memory server to a backup storage system of data pages indicated as modified by the data modification tracking structure stored at the memory server.
