Aloha,
I am attempting to set up an Ovirt environment across every server that I currently
manage. I have a set of servers in one location, behind a single firewall with multiple
IP's, and I have another set of servers in a second location halfway around the world,
also with their own set of IP's. Additionally, the servers have different types of
Intel CPU's, and varying amounts of memory and storage. I also have a Fiber Optic SAN
that I would like to use as my storage.
My question is: Do I have to set up a VPN between every server that I want to install
Ovirt on in order to manage them under a single Ovirt installation? If so, how would I
gain a highly available scenario? In this case, if the server acting as the VPN server
failed, the entire Ovirt system would collapse as well due to inability to communicate.
My goal is to combine the resources of all of my servers so that I can live migrate
VM's between them based upon workload, and also availability of hardware. If the
servers in Canada fail for instance, I want the services to automatically migrate to my
servers in Hawaii.
Any assistance you can provide would be greatly appreciated. Thank you!

Hi Trenton,
From what you described, you have two sets of servers in two
locations.
With the right network architecture it should be ok to have just one
(with no HA) VPN connection between the two locations.
To achieve HA, you would need at least two redundant VPN connections,
as well as redundant switches in both locations.
Let me know if you have any further questions.
Thanks,
Marcin

Do you have the same SAN at both locations? Are you able to set up async
replication between the two SANs?
My question is: Do I have to set up a VPN between every server that I

installation? If so, how would I gain a highly available scenario? In

You need to have a VPN link between two sites, preferably a redundant one,
and with some serious bandwidth too, if you intend to replicate the SANs
across it. Once you have a replica of your storage domain on the second
site working, if the primary site goes down, you can bring everything up on
the secondary site. If you want this at a VM and not SD level, you might
either have to replicate LUNs separately and use direct LUNs for VMs, or
write some management scripts around it, so you will never end up with the
same VM started on both sites. The latter will also require active-active
LUN replication, which is usually a bad idea to start with.
My goal is to combine the resources of all of my servers so that I can
live migrate VM's between them based upon workload, and also availability
of hardware. If the servers in Canada fail for instance, I want the
services to automatically migrate to my servers in Hawaii.
load balancing will be very tricky, DR - much easier.
