Windows Server 2012 Dynamic Memory Improvements

Dynamic memory first appeared in Windows Server 2008 R2 Hyper-V, which enables virtualized hosts to use physical memory more efficiently and distribute it to virtual machines running on the host. Dynamic memory technology can adjust the amount of memory a virtual machine can use in real time. These memory allocation adjustments are based entirely on the virtual machine's memory requirements and the configuration parameters of the dynamic memory on the virtual machine.

dynamic memory technology provides tremendous scalability and performance gains, especially in the Virtual Desktop Infrastructure (VDI) environment, in this environment, within a specific time, there will be a lot of running on the host The virtual machine in is idle or in a low load state.

memory by using a dynamic scenario like this, to integrate a larger number of virtual machines to Hyper-V host. In the end, only a small number of hosts are needed to provision virtual desktops for more users, and this means you don't need to buy too many high-end server hardware. In other words, dynamic memory technology can save you money.
