What is storage migration vMotion?

With Storage vMotion, you can migrate a virtual machine and its disk files from one datastore to another while the virtual machine is running. With Storage vMotion, you can move virtual machines off of arrays for maintenance or to upgrade.

Does storage vMotion require downtime?

Storage vMotion is a newer technology from VMware that allows migrating all virtual machine files from one storage location to another while the VM is powered on and without any downtime.

How does live VM migration work?

In live migration, the static part (not changing or having any active write operation) of the VM is transferred first while VM keeps running on the source server. Then VM is suspended and the remaining part is transferred. Live VM migration reduces the down time but engages more resources for a longer time.

How storage vMotion works in background?

Storage vMotion invokes a Fast Suspend and Resume of the virtual machine (similar to vMotion) to transfer the running virtual machine over to the idling shadow virtual machine. After the Fast Suspend and Resume completes, the old home directory and virtual machine disk files are deleted from the source datastore.

What happens storage vMotion?

Storage vMotion is a component of VMware vSphere that allows the live migration of a running virtual machine’s (VM) file system from one storage system to another, with no downtime for the VM or service disruption for end users. This migration occurs while maintaining data integrity.

How do you use storage vMotion?

  1. First login to vSphere web client. Choose the VM which storage you want to migrate.
  2. Right click the VM which storage you want to migrate. Choose the option “Migrate.”
  3. Migration Wizard will open here.
  4. Here you can do multiple things.
  5. Now we are ready to do Storage vMotion.

What are the types of VM migration?

There are two types of VM migration: cold and live. Cold migration occurs when the VM is shut down. Live migration occurs while the VM is actually running.

How do I speed up storage on vMotion?

The easiest way to accelerate vMotion is using 10Gbit connection. This method provides not only better bandwidth but also more concurrent vMotions. If a vMotion is configured with a 1GB line speed, it is possible four concurrent vMotion, while with a 10GB link speed – eight concurrent vMotions per host.

How is live migration done?

Live migration is usually performed when a physical host machine (computer or server) needs maintenance or an update, or when a VM must be switched to a different host. The process transfers the VM memory, network connectivity and storage. Most of the migration occurs while the OS continues to run.
