Hi
I've looking for some ideas about designing disaster recovery planning with ovirt 4.2. Since 4.2 we have options to have intergration with disaster recovery site also. I went through some videos at internet and want to share if those are correct or not. Thus you can help me regarding what other things I should be having ideas during planning and designing more about this.
1. We've to keep both sites on and already created datacenter, cluster and one site with storage domain attached and other site with no storage domain.
2. We've to keep latency of 10ms at maximum between both sites.
3. Have to configure virtual machines with affinity group.
4. The VM's which are configured as high-available vm, will be migrated first.
5. There's an Ansible script while have to run to fail over and fail back.
Now, please could you help me out regarding this.
1. Where can I find this ansible script? Is this https://github.com/oVirt/ovirt-ansible-disaster-recovery.git?
yes. Note the youtube links on that.
@Maor for the rest of your questions.
2. Can this script run at rhv also ? or just for ovirt? Or what other changes I have to make for rhv to have this functionalities?
3. How ovirt/rhv works with the OVN compared to NSX? Is there's any challenges ?
4. Can you share me some high and low level diagram related to rhv disaster planning?
5. How the storage migrates on backend ? During the script ?
6. Where do I run this script? During fail over at primary site and during fail back at secondary site?
7. Basically since only the storage migrates and all other components are on already so basically backend it's only dealing with storage migration according to defined policies ?
Please could you help me out with some designing and ideas what're the best architecture during planning on disaster recovery at RHV.
If you are a Red Hat customer, a Red Hat Consulting engagement could also help.
Thank you.
