SQL Server 2012 - DB Mirroring + Log Shipping + Multi-Subnet

$

Hi again,

So AG would be nice to have, but considering the costs of getting it, well, it is a no go for me at the moment (This is like a 1:20 ratio considering Std comes with server licencing and enterprise is only per 2 cores).

So, having 2 sites, with different subnet. Is it possible to configure automatic failover for DBM ? We are running Windows 2012 R2 which supports multi subnet failover. But what about DBM in this case ?

Can the witness be configured on a third site ? (I was thinking of having the following weights: Site 1:2, Site 2:1, Quorum:2 just to have no reconfig to do in case of Datacenter failure)

Also, in order to offload some of the backup load as the DB are somewhat big (1TB), I was thinking of having one additional node per site to which the logs are shipped and that are used to run the backups. The question being, is it possible to log ship from each "primary" on each site rather than have the primary on site 1 do it for all the servers across the subnets ?

It would be a setup like this:

Site 1 Primary <---DBM---> Site 2 Primary (Hot failover)

Site 1 Primary <---LogShips---> Site 1 Secondary

Site 2 Primary <---LogShips---> Site 2 Secondary

And thus reduces the load on the link between the 2 sites.

I do hope to see AG in the future for Std as they are removing DBM in the next version.

Thanks,
