摘要:
A system and method is illustrated for identifying an Input/Output (I/O) driver module, using a hypervisor, to receive a read command to read a virtual memory page from a remote memory location. Further, the system and method includes reading the remote virtual memory page, using the I/O driver module, into a memory buffer managed by the I/O driver module. Additionally, the system and method includes storing the virtual memory page in the memory buffer to a persistent storage device. The system and method also includes identifying a remote super page, using a hypervisor, the remote super page including a remote sub page. Additionally, the system and method includes identifying a local super page, using the hypervisor, the local super page including a local sub page. Further, the system and method includes swapping the local sub page for the remote sub page, using the hypervisor, the swapping occurring over a network.
