Systems and methods for caching data from a plurality of virtual machines may comprise detecting, using a computer processor executing cache management software, initiation of migration of a cached virtual machine from a first virtualization platform to a second virtualization platform, disabling caching for the virtual machine on the first virtualization platform, detecting completion of the migration of the virtual machine to the second virtualization platform, and enabling caching for the virtual machine on the second virtualization platform.

System and method for caching virtual machine data

Systems and methods for caching data from a plurality of virtual machines are disclosed. In one particular exemplary embodiment, the systems and methods may be realized as a method for caching data from a plurality of virtual machines. The method may comprise detecting, using a computer processor executing cache management software, initiation of migration of a cached virtual machine from a first virtualization platform to a second virtualization platform, disabling caching for the virtual machine on the first virtualization platform, detecting completion of the migration of the virtual machine to the second virtualization platform, and enabling caching for the virtual machine on the second virtualization platform.

Techniques for epoch pipelining are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for epoch pipelining comprising the steps of beginning a first epoch, determining for one or more pages of memory if the pages of memory are likely to be modified in a subsequent epoch, performing a first operation on the pages of memory that are likely to be modified in a subsequent epoch, beginning a second epoch, subsequent to the first epoch, performing a second operation on the pages of memory that are not likely to be modified in a subsequent epoch, and ending the first epoch, wherein the first operation and the second operation are dissimilar.

Techniques for improving dirty page logging are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for memory logging comprising the steps of determining for one or more pages of memory if the pages of memory are likely to be modified in a subsequent epoch, performing a first operation on the pages of memory that are likely to be modified in a subsequent epoch, and performing a second operation on the pages of memory that are not likely to be modified in a subsequent epoch, wherein the first operation and the second operation are dissimilar.

Method and apparatus for transactional fault tolerance in a client-server system is described. In one example, output data generated by execution of a service on a primary server during a current epoch between a first checkpoint and a second checkpoint is buffered. A copy of an execution context of the primary server is established on a secondary server in response to the second checkpoint. The output data as buffered is released from the primary server in response to establishment of the copy of the execution context on the secondary server.
