- We have two separate but identical sites (Production and Disaster Recovery)
- Both sites will have their own infrastructure of 3x servers, 2x iSCSI switches, and 1x SAN
- Data from production site will be replicated to DR site quite regularly (may be real-time)
- Sites utilize VMware ESXi/vSphere 6.5 and will have Acceleration Kits
We are in the process of an infrastructure upgrade, and am in the planning phase of implementation. Once we have all of the above fully implemented, how can I configure a proper fail over and fail back configuration? I am pretty sure I may be able to configure High Availability on a single site for a failure of a single host; would it be possible to configure some type of fail over should a disaster completely bring down an entire site (if building hosting production equipment burns down)?
Is it even possible to utilize VMware High Availability to fail over to another site/SAN? If it was a temporary failover (power at production site is lost, then comes back), would there be an automatic fail back?
Can I use this method to temporarily take down a site for maintenance while having no impact to end users?
Thank you in advance for any assistance provided.
