Question

What is the difference between  vMotion and svMotion? Why would you use vMotion or svMotion?

Answer 1

SOLUTION:- The differences between vMotion and svMotion are given below:-

(1) vMotion permits an administrator to move a running VM from one physical host to another physical host without having to power off the VM. On the other hand, svMotion confers the ability to move storage for a running VM between datastores.

(2) vMotion allows migration of a VM from one physical host to another without disrupting the user. On the other hand, svMotion avoids app downtime for planned storage maintenance by allowing the migration of the VM files across arrays while the VMs are running. Local svMotion requires VM's powered off and share svMotion is live migration where VM's can be powered on.

Reasons for use of vMotion or svMotion: In order to execute the live migration of running virtual machines from one physical server to another with eliminating the need for server downtime, continuous service availability, complete transaction integrity and to select separate locations for the virtual machine disk files & to migrate virtual machines from one datastore to another, we would use vMotion or svMotion. For example, If we need to move the mail server to the new, faster storage, but the server can't be taken offline to make the change, then we will use svMotion. Distributed Resource Scheduler (DRS) which is the feature of vCenter utilizes the vMotion during the automated load balancing of virtual machines.
