摘要
An example method of providing deduplication support for remote direct memory access (RDMA) memory includes detecting that a first memory page and a second memory page are identical. A first mapping maps a first virtual memory address (VMA) to a first physical memory address (PMA) of the first memory page. A second mapping maps a second VMA to a second PMA of the second memory page. An RDMA memory region includes the first memory page. The method also includes updating the first mapping to map from the first VMA to the second PMA. The method further includes re-registering the RDMA memory region for RDMA.
