We are in a requirement that our DR site is 200+ KMs apart from our office premises and connectivity over WAN. This DR site also going to deploy with Ussuri version. How we can setup the DR site so effectively so that, when VMs or Physical hosts in our DC clusters crashes or abruptly power to one physical machine got break due to electrical wire pulled out/unplugged , then how automatic failover to the DR site which is 300 miles away from our DC . what will be the solution for this setup so that automatically the VMs crashed in our DC will be served from our DR site with minimum latency or zero downtime (is zero down time possible ? kindly enlight on this or how to achieve near zero down time ) using OpenStack without any data loss ( is this possible no Data Loss ?). How ? Whats the best architecture for this using openstack, what all are the tools components need to be used ? and what type of solutions need to be deployed for the above requirement. VMs are nearly 100 nos and Linux and Windows majority of them with around 100 GB to 200 GB size for each VM. Kindly share your thoughts and expertise in this regard and enlighten me on what techniques / components of OpenStack need to be employed for achieving this. Any hints and tips and reference links highly appreciated. Thanks in advance, Kris -------------- next part -------------- An HTML attachment was scrubbed...
