I would like to move two virtual servers from SiteA and put in SiteB to address performance issues
I need help finding solutions for failing over those two servers back to SiteA in the event that SiteB goes down?
My concern is if SiteB is running those two servers and the internet goes down, would SiteA consider that an HA or FT event and spin up those servers? Meanwhile SiteB users are still making changes locally to those servers. What would happen when the internet comes back online?
We are currently running Citrix Xenserver, however we are due for a refresh which will most likely include vmware. I’ve looked into vmware’s stretched clustering which has very high requirements of 622Mbps. We are running 100/100Mbps Fiber at SiteA and 200/200Mbps Fiber at SiteB
Initially my thought was to setup SQL clustering on Server1 and setup DFRS w/ namespace on Server2. I wasn’t too comfortable with DFSR as I have had issues with large files being stuck in the staging folder and never completing replication. So I started looking outside of OS replication and to VM or Server replication.
Current environment layout:
SiteA – Hosting all server; remote offices are connected via site to site VPN
SiteB – Main office which has a physical domain controller and access all other servers over the VPN
Server1 – SQL server
Server2 – File server which SQL server references
Any help would be much appreciated. We are looking to automate process.
