Subject: Planners

Hello All ,

We are discovering compute offering section and couldn¹t understand something 
about planner.

Looks like deployment planner is like intelligent placement on Hyper-v or 
Vmware DRS but only the placement part.

First we can not find explanations of implicitdedicationplanner and bare metal 
planner , any one know about it ?

Second what is planner mode ? What is relation between deployment planner and 
planner mode ? If we choose deployment planner must we set the planner mode too 
? 

Maybe sounds like stupid but , another thing is we can not imagine some 
deployment planners, for example if we are running cloud and have a resource, 
default behaviour should be spread everything almost equal , why people want to 
put vms depend same account on same pod/cluster or what happen if i have small 
number of vm on host but there is high resource usage on that hosts. For 
example KVM do not have an option like vmware drs , how cloudstack handle 
spread of vms on KVM cluster ?

Regards
VM
