  • Patent number: 12524258
    Abstract: Disclosed herein are a method and apparatus for migrating a virtual machine in a memory-disaggregated environment. The method for migrating a virtual machine in a memory-disaggregated environment includes determining whether to migrate a virtual machine based on a number of accesses to a remote memory, establishing a migration policy for the virtual machine based on a remote memory access pattern, and determining a migration destination node based on the migration policy, wherein the migration policy includes a first migration policy corresponding to a case where the remote memory access pattern is sequential, and a second migration policy corresponding to a case where the remote memory access pattern is non-sequential.

  • Patent number: 12153525
    Abstract: Disclosed herein are a method and apparatus for verifying integrity in a memory-disaggregated environment. The method for verifying integrity in a memory-disaggregated environment includes receiving write data and multiple hash values generated based on write data from a remote memory, and verifying integrity of the write data based on the write data and the hash values, wherein verifying the integrity of the write data comprises selecting a hash value for the integrity verification based on an access latency of the remote memory.

  • Patent number: 11849005
    Abstract: Disclosed herein are a method and apparatus for accelerating network transmission in a memory-disaggregated environment. The method for accelerating network transmission in a memory-disaggregated environment includes copying transmission data to a transmission buffer of the computing node, when a page fault occurs during copy of the transmission data, identifying a location at which the transmission data is stored, setting a node in which a largest amount of transmission data is stored as a transmission node, and sending a transmission command to the transmission node.
