Vmotion/HA for dummies

We have an ESXi 4.1 host running 2 guests via an NFS NAS datastore.  We just put in an identical physical server and purchasd vmware essentials plus.
I need a quick how to on setting up vmotion and ha.  With all the product names its hard to tell what needs to be installed.
I have the Vsphere client installed on 32bit windows server to manage the esxi host of course.
I can access the new esxi4 host as well with the client.
I put in the license key on both hosts.
I have not attached the datastore to the new server its just got initial configuration.
now what...?
I thought I would magically have right-click options to vmotion and configure HA.
Some googleing and looking at my vmware account I see downloads for vshere server which requires a 64bit server to run on.  Is that needed?

Yes, it is needed.

This can be installed on a physical or virtual server.

ah thats the ones I was looking for. thanks
so i can install vshere server onto a guest os

I have the 64bit guest so Im ok there.

I do have dual nics on both server but currently only using one.  I want to get it "running" then tune it etc.

thanks for the steps. I knew I was missing some peice. lol. I use esxi alot but never a paid version before so this should be fun.
Yes, physical or virtual server.

We often install on virtual server these days. To reduce the physicals requried.
ok but if I only have the 2 hosts and the vshpere server is hosted as a guest on them and one goes down how doe vcenter tell the other server to start up the guests if it is one of the guests that just went down?  Or is vcenter allowing changes to ESXi that you cant do via the console client directly?
Good Question.

That's what you've got HA for!

If one host fails, after x minutes, the vCenter VM will be moved to the other host.

But what we normally do, is make sure vCenter VM is the always the first VM to start.

you can always fall back to manage machines directly like you do at present, if vCenter is not available.
and if doing maintance on one host, you'd move it to the other etc

But by Entering Maintenance Mode on the host, with HA, vMotion it will do this automaitcally.
oh, and to enable HA, you need to Create a cluster, and add your servers to the Cluster before enabling HA.
OK so the vshere server does not have to be running for ESXi to transfer to the second ESXi server and it will automagically start the guests in the order I set.
Just want to make it clear in my crain that the vshere server is not what "tells" the second server to start the guests.  The second server starts them because it hasnt heard from the first server in x seconds.  correct?
I can really recommend the following book, which tells you alot more, than the Config Guides


VMware vSphere 4.1 HA and DRS Technical deepdive

part of HA, if no hearbeat from server in cluster, machines are started on another host, it's far more complex than that. Suggested Reading above.
yea just looking for the overview.  perfect.  thanks.
Lots of new stuff for you to configure.

If you get stuck, post another question, I'm sure myself and the other Experts will be here to answer it.
