Abstract: Embodiments pertain to live storage migration for virtual machines. Specific embodiments can implement the migration of VM disk images without service interruption to the running workload. Specific embodiments relate to storage migration between different disk arrays. Embodiments of the subject invention relate to a method and apparatus that can enhance the efficiency of virtual machine (VM) live storage migration in heterogeneous storage environments from a multi-dimensional perspective, e.g., user experience, device wearing, and/or manageability. Specific embodiments utilize one or more of the following: adaptive storage migration strategies, or techniques, such as 1) Low Redundancy (LR), which generates a reduced, and preferably the least, amount of redundant writes; 2) Source-based Low Redundancy (SLR), which can help keep a desirable balance between IO performance and write redundancy; and 3) Asynchronous IO Mirroring (AIO), which seeks high, and preferably the highest, IO performance. Specific embodiments adaptively mix one or more of these adaptive storage migration techniques during massive VM live storage migration.

Abstract translation: 实施例涉及虚拟机的实时存储迁移。 具体实施例可以实现VM盘图像的迁移，而不会对运行的工作负载造成服务中断。 具体实施例涉及不同磁盘阵列之间的存储迁移。 本发明的实施例涉及一种方法和装置，其可以从多维角度（例如，用户体验，设备佩戴和/或可管理性）提高异构存储环境中的虚拟机（VM）实时存储迁移的效率。 具体实施例使用以下中的一个或多个：自适应存储迁移策略或技术，例如1）低冗余（LR），其产生减少且优选地最少量的冗余写入; 2）基于源的低冗余（SLR），可以帮助保持IO性能与写冗余之间的理想平衡; 和3）异步IO镜像（AIO），寻求高，最好是最高的IO性能。 具体实施例在大规模VM实时存储迁移期间自适应地混合这些自适应存储迁移技术中的一个或多个。
