Does vMotion work without shared storage?

vMotion does not require environments with shared storage. This is useful for performing cross-cluster migrations, when the target cluster machines might not have access to the storage of the source cluster. Processes that are working on the virtual machine continue to run during the migration with vMotion.

What happens if storage vMotion fails?

If something occurs while the copy is in progress that results in insufficient disk space on the target data store (for instance, if a new VM is created), the Storage vMotion process fails, the files copied to the target datastore are deleted, and the VM continues to run on the source data store.

What are the reasons for vMotion failure?

If the target host does not have enough memory to satisfy the reservation of the virtual machine, vMotion will fail. To fix this, migrate the virtual machine to another ESXi host that can provide the guaranteed memory for the VM or reduce the memory reservation of the virtual machine.

What is the difference between vMotion and storage vMotion?

Summary: VMware vMotion vs vMotion Storage But there are some significant differences: VMware vMotion allows you to move VMs from one ESX server to another without downtime for users, while the data store can be mounted on both the source and target hosts.

Does storage vMotion affect performance?

Storage vMotion consumes a lot of resources during the migration of a virtual machine, especially processing power. It can also affect the performance of other virtual machines on your network during the process. Few data centers are willing to let go of the time, labor, effort, and resources to use Storage vMotion.

How long does storage vMotion take?

It took 7.5 hours to storage vmotion across 1.7TB worth of machine\storage.”

What are the prerequisites for vMotion?

vMotion in an environment without shared storage is subject to the following requirements and limitations:

  • The hosts must be licensed for vMotion.
  • The hosts must be running ESXi 5.1 or later.
  • The hosts must meet the networking requirement for vMotion.
  • The virtual machines must be properly configured for vMotion.

How do you initiate vMotion?

To perform a simple vMotion of a virtual machine on any given ESXi host, login to vCenter Server, right-click on a virtual machine and select Migrate. The migrate wizard will launch allowing you to select the type of migration to be performed.

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.
