Introducing vSphere vMotion
vSphere vMotion is a VMware technology used to migrate a running virtual machine from one host to another without altering its power state. The beauty of the whole process is that it is transparent to the applications running inside the virtual machine. In this section, we will understand the inner workings of vMotion and learn how to configure it.
There are different types of vMotion:
Compute vMotion
Storage vMotion
Unified vMotion
Enhanced vMotion (X-vMotion)
Cross vSwitch vMotion
Cross vCenter vMotion
Long Distance vMotion
Compute vMotion is the default vMotion method and is employed by other features such as DRS, FT, and maintenance mode. When you initiate a vMotion, it initiates an iterative copy of all the memory pages. After the first pass, all the dirtied memory pages are copied again by doing another pass and this is done iteratively until the amount of pages left over to be copied is small enough to be transferred, and to switch over the state of the VM to the...
