- 1- In vmware they use the following terms:<br />
High Availability<br />
DRS<br />
Vmotion<br />
<br />
&nbsp;how they are different?<br />
<br />
2- when VM machine needs more resources that can not be provided by the current ESX server, then it moves to another ESX server.<br />
&nbsp;in this case, I believe the VM machine doesn't reboot in order to move from one ESX to another. How does this operation called? HA or Vmotion or DRS?<br />
<br />
-3- when an ESX server that is servicing multiple VMachines fail, the vmachines will move to another ESX server. Would these vmachines reboot before they move to the ESX server? how do we call this operation vmotion,DRS,HA?<br />

Assuming of course there is SAN storage implementation<br />

Vmware terminology

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
