What is a vMotion?
What is a vMotion?
at a glance VMware® VMotion™ enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. VMotion is a key enabling technology for creating the dynamic, automated, and self- optimizing data center.
What happens in a vMotion?
VMware vMotion keeps track of the ongoing memory transactions in a bitmap. Upon completion of the data transfer, vMotion suspends the source VM, copies the bitmap to the target host, and resumes the VM’s activities. The entire process is performed in such a manner so as to ensure transaction integrity.
How many types of Vmotions are there?
vMotion Migration Types. There are three main types or modes of vMotion as listed next.
Why do you need vMotion?
vMotion enables IT departments to migrate individual VMs from a private data center to a public cloud as needed. Be sure the cloud provider can match both the hardware and software requirements for compatibility. Alternatively, migrating powered-off VMs reduces the compatibility requirements.
When was vMotion introduced?
2003
The first iteration of VMotion (yes, it originally had a capital V) was released with VMware Virtual Center 1.0 in 2003.
How long does a vMotion take?
Transfer the virtual machine’s active memory and precise execution state over a high-speed network, allowing the virtual machine to switch from running on the source vSphere host to the destination vSphere host. This entire process takes less than two seconds on a gigabit Ethernet network.
What is EVC VMware?
VMware Pages You can use the Enhanced vMotion Compatibility (EVC) feature to help ensure vMotion compatibility for the hosts in a cluster. EVC ensures that all hosts in a cluster present the same CPU feature set to virtual machines, even if the actual CPUs on the hosts differ.
What is VMware and types?
VMware is a virtualization and cloud computing software vendor based in Palo Alto, California. VMware products include virtualization, networking and security management tools, software-defined data center software, and storage software.
