SQL server 2014 Always On Availability groups requirement/deploy question
Posted on 2014-12-28
Hello Experts team,
I am a little confused here in regards to cluster requirements to deploy SQL 2014 Always On availbility groups for a couple of servers in one site or across sites.
I would like to deploy SQL 2014 Always Availability group following design below. Please, let me know if that is not possible
Two Virtual machines running Windows 2012 R2 standard edition and SQL 2014 enterprise edition in one site,.
One VIrtual machine deployed on a secondary or DR site
Do I have to install traditional MSCS failover cluster for SQL servers and instances on site 1? or I just need to install failover cluster component?
If so, Do I have to setup 2 virtual NICs for each VM? one for intracluster communication and the second one for production communication?.
If not, can you please attach a link step -by-step to deploy SQL server 2014 Always ON availability groups for a couple of servers in one site, and then replicate information to a DR site?
Once the HA question is clarified, how can I replicate the information from main site to DR site? Can i still use SQL Always on AG, or should I pick up another replication method?
Please, be aware that my client is looking for HA and DR for this design, but according to all blogs and documentation I've read so far, SQL server 2014 for VMware is supported only on a Non-shared disk, meaning that the traditional cluster is not an option. Here is my confusion. I understand that your team only supports SQL and HyperV, but according to VMware official KB, SQL server Always On availability groups is supported only on non-shared disk
