Hi Jomy,

Our Windows Failover Cluster options with VVR are not a robust as the SFW-HA GCO with VVR solution.  As a result, the components to control replication migrate and takeover functions are not available to the basic Windows Failover Cluster configurations.

 

We do have a solution that works with Windows Failover Cluster when clusteirng virtual servers with Hyper-V but it requires hardware replication such as EMC SRDF.  If you are clustering Hyper-V VMs then this might be a solution for you.

 

Thank you,

Wally

Environment Details

OS platform: Windows 2012 STD.
Database: MS SQL 2012 -------- (DB server is Active –Passive Cluster).

SAN Storage: HP P6000 series.

same configuration on primary and secondary site

We want to replicate primary site's data base to secondary site and secondary site should get up

in the case of primary site is down

looking for a solution with this senario.

Hi Jomy,

The licenses that you mention would not include Windows Failover Cluster.  But it does include the HA/VCS product with GCO and VVR.  This solution would allow for minimal interaction or fully automated site to site failover.

You need to look at the SQL 2012 HA/DR solutions guide for the 6.0.2 product.  This covers Windows 2012 and SQL 2012 in a 2 site GCO setup using VVR.  Here is a link to that guide:

Here is where you can find all of the guides for the 6.0.2 product line.

Keep in mind that Symantec Technical support is available 24 x 7 x365 to assist you with any problems that you might have with our software.  Please reach out to us and open a case if you have some problems with this configuration or need some guidance on how to set it up.  This is a very complicated solution and can be very overwhelming the first time that you set it up.

Thank you,

Wally

Hi Jomy,

I don't understand your last query. 

 

SFW-HA can be configured with single node clusters at both sites. 

SFW with VVR on a standalone server can be used to replicate SQL data to a remote server also running SFW with VVR.

The one thing to keep in mind when setting up VVR with SQL is to keep the volumes used for SQL Database files and their associated log files in the same Replicated Data Set (RDS).  This will maintain write order fidelity between the SQL database and log files which will keep them in a good state on the VVR secondary site.

Thank you,

Wally

Hi Wally,

do let us know the ip requirement at primary and DR site

Hi Jomy,

 

Here is the basic rundown on IPs needed for a GCO configuration.

 

Production site:

* Each server needs an Admin IP.

* 1 IP for the Cluster Service group used by GCO for cluster heartbeats.

* 1 IP for VVR to use for replication.

* 1 IP for the Global application.

* Additional IPs may be needed depending on enviornmental needs such as dedicated backup networks or any local groups that might need to be configured.

For a 2 node Production site cluster using VVR with a single global application service group, you would need a minimum of 5 IPs.

 

DR site would have the same IP requirements.

For a 1 node DR site cluster using VVR with a single global application service group, you would need a minimum of 4 IPs.

 

Thank you,

Wally
