Should each CSS in HA mode install with a local DB or remote SQL Cluster ?

A question on installing MS SQL server on 2-nodes CSS setup using CSS built-in failover feature. Will CSS ensure data are replicated from the primary CSS node to the secondary CSS nodes ?



Hi Chuan,

When configuring CSS in HA mode, there is no data replication, once both CSS point to the same database.

For more information about how to configure failover for CSS, check this link.

Hope that helps,


Note, this means the CSS service is HA, but the database it relies on is NOT. It's best to have the database on a different server entirely, so an outage of either CSS won't take out the database too.

Thanks Chris. Noted. This would increase the cost :(. I will check with my local Dynatrace Rep.
