Hello,
I have a two node windows 2012 cluster on which I have configured SQL Server 2012 High Availability Groups.
These two SQL server nodes are in different data centers.
These are used by ASP.NET application which is also running in 2 node NLB Cluster with each node being in a data center.
The following diagram depicts my setup
Now I when configuring the cluster, I am configuring it with "Node and File Share Majority"
I do not use any SAN at all. no Shared Storage.
I don't have any other data center. So no 3rd data center. Only 2 data centers.
Currently I have created a fileshare on web server 1 and configured the cluster. The problem is that if I loose the data center 1. then my cluster will go down. desptite the fact that my Web Server 2 and SQL Server (Mirror) are alive.
My intention is that even when an entire data center is down. my application contiues to work because I have all the components of my application (web server and database server) in the second data center.
Currently the file share is a single point of failure and since I don't have shared storage across data centers if the machine on which the file share resides goes down, then the cluster goes down... even though it has healthy machines in other data centers.
How do I resolve this? Can I provide 2 file shares? one on web server 1 and second on web server 2 as witness?
