Live Migration
Improved Live Migration Windows Server 2012 R2 takes full advantage of your hardware to reduce the time required to live migrate virtual machines. It is now faster and easier to manage and maintain and your private cloud infrastructure. When maintenance or upgrades are required on your server running Hyper-V, live migration enables you to quickly migrate your virtual machines. This reduces the time it takes to monitor lengthy migration operations.You can also quickly and efficiently balance your virtual machine workloads. In Windows Server 2012 R2, live migration provides three options to reduce the time required to live migrate your virtual machines. You can choose to use memory compression. Alternatively, you can choose to use Remote Direct Memory Access (RDMA) functionality (which requires RDMA-enabled adapters) or multichannel network adapters.
Faster Live Migration (less than 10 GB)
In environments where hardware and networking resources are constrained, live migration delivers performance improvements for migrating virtual machines by compressing the memory data before sending it across the network. This utilizes spare CPU capacity available in the server running Hyper-V. Hyper-V closely monitors the CPU requirements of the virtual machine and only consumes an appropriate amount of CPU resources to quickly move virtual machines from one server to the next.
Faster Live Migration (greater than 10 GB)
In environments where networking resources are not constrained, you can configure live migration to use multi-channel network adapters or RDMA-enabled network adapters, which reduces the time required to live migrate virtual machines.
Live Migration with RDMA-enabled Network Adapters
Hyper-V compresses virtual machine memory transferred across the network. Hyper-V utilizes available CPU resources on the server running Hyper-V to reduce the network load. Migrated Virtual Machines Virtual Machine More efficient use of CPU resources Server Running Hyper-V Server Running Hyper-V Live migration compression is enabled by default. Virtual Machine Virtual Machine You can implement multi-channel functionality while using live migration. Each host computer is configured with dual 10 GB Ethernet network adapters. Server Running Hyper-V Virtual Machine Server Running Hyper-V GbE (Gigabit Ethernet) Network Connectivity Virtual Machine Computers that are running Windows Server 2012 R2 can be equipped with RDMAenabled network adapters that deliver significantly faster live migrations for your virtual machines. RDMA is able to perform a direct memory access from the memory of one computer into that of another without involving the operating system. This permits highthroughput, low-latency networking and delivers greater efficiency with live migration.
Live Migration with Multi-Channel Network Adapters
Windows Server 2012 R2 servers running multi-channel network adapters installed can perform faster live migrations for your virtual machines. Large virtual machines can be migrated simultaneously, utilizing multiple network adapters and hence achieving faster migration efficiencies.
