System and method for migrating virtual machines

摘要

A method, computer program product, and computing system for receiving an indication that a target virtual machine is going to be migrated from a first operating environment to a second operating environment. The target cache system is associated with target virtual machine. An auxiliary virtual machine is generated within the second operating environment. An auxiliary cache system is associated with the auxiliary virtual machine. The target virtual machine and the auxiliary virtual machine are connected. IO requests for the target virtual machine are mirrored to the auxiliary virtual machine. At least a portion of cache data included within a target memory system associated with the target cache system is copied to an auxiliary memory system associated with the auxiliary cache system. The target virtual machine is migrated from the first operating environment to the second operating environment.

1. A computer-implemented method comprising:
receiving an indication that a target virtual machine is going to be migrated from a first operating environment to a second operating environment, wherein a target cache system is associated with the target virtual machine; generating an auxiliary virtual machine within the second operating environment, wherein an auxiliary cache system is associated with the auxiliary virtual machine; connecting the target virtual machine and the auxiliary virtual machine; mirroring IO command requests for the target virtual machine to the auxiliary virtual machine; copying at least a portion of cache data included within a target memory system associated with the target cache system to an auxiliary memory system associated with the auxiliary cache system; disconnecting the target virtual machine from the auxiliary virtual machine; processing the IO command requests that were mirrored from the target virtual machine to the auxiliary virtual machine; and migrating the target virtual machine from the first operating environment to the second operating environment including downgrading a mode of operation of the target cache system including, for a received write request, writing content associated with the received write request directly to a data array associated with the target virtual machine without writing the content associated with the received write request to the target memory system.
