I need some guidance with a VMWare project I'm working on. I'll explain what I'm trying to achieve first, then I'll list what I have, and what I've done so far (of course if i went wrong anywhere along the line, I don't mind taking steps back for the sake of moving forward in a proper manner.) First time i'm doing something like this, and it seems I'm in over my head and I seek help.
The situation we are looking to achieve is as follows;
- Site A - 2 Hosts (Host A, Host B) + 1 Synology RackStation (NAS1)
- Site B - 1 Host (Host C)
Important Software:
Veeam Backup and Replication 9.5
VMWare ESXi 6.5
The Situation
All hosts have VMWare ESXi 6.5
Host A is intended to be the primary host, with Host B being a secondary host that will remain powered off unless Host A fails for any reason, then Host B will be powered on, thus, the Datastore has to be somewhere independent of Host A and Host B (which is where the Synology Rackstation was supposed to come into play).
Site B is meant to be a disaster recovery (DR) site. Upon failure of the entire site, then Host C located in Site B is meant to be powered on manually and those VMs located at site A should be accessible in Site B because we intend to use the replication feature of Veeam Backup and Replication to send replications of the VMs to Site B.
What we did
We setup the Synology Rackstation to be an iSCSI target, with the thought that it would be then accessible by both Host A and Host B , however, it is only accessible by the first come (which was Host A in this case).
My question is; is this really the best way to go about setting up what we wish to achieve? If yes, then what did we do wrong (of course you can request more details and i'll provide as best as i can). If it is the wrong way we went about it, please advise the right way (using the current equipment we have)
