Hi All,
Can anyone please assist and suggest me in what sort of replication technology to choose and combine in order to minimize the multiple Application Server downtime when the OS for the SQL Server is patched ?
this is the diagram that I have with the current budget and hardware that has been purchased by the management.
As per the diagram above, I have been granted 1 Physical server in each site with no storage array replication.
I haven't decide which replication technology or what version of the SQL Server to use 2008 / 2012, but for now the proposed solution is to use Prod - DR replication.
The downtime that is acceptable is 15 minutes maximum per day for the failover and patching.
