HA and DR together

[Nusret Fetlyaev]

We have Live Site Recovery deployed and operational for a single VM over two geo-separated sites, physically connected over Dark fiber of 5 miles distance.
We use VM based VR as each of two hosts uses its internal disks as storage. 
Storage usage of the VM is 1.5 TB. DCI is 1 Gbps with 2 msec latency. 
Now we consider to deploy HA for the same VM at Site A only while we want to keep the Live Site Recovery in place. 
So, we consider to move the VM from the internal storage to a shared storage reachable from both sites via iSCSI. 
Next we should add Host B to Cluster A and enable HA. 
We assume Host B can be a part of both Custer A (for HA) and Cluster B (for DR), and we don't need to change its Mgmt IP address.
Please confirm if the above is feasible.

If I understand your request, you have Sites A and B, and they have one or more ESXi, and you have shared storage. If your network can present the same IP ranges on both Site A and B, you can create a stretched cluster. This would remove the need for Live Recovery.

[Duncan Epping]

Just to make sure you understand, a host can only be part of 1 cluster. You cannot add host B to Cluster A and have it be part of Cluster B at the same time. This is not an option.

If you want to add HA in Site A you will need to add a host to Site A as well.
