I had explained about the Datacenter Activation Coordination (DAC) Mode in one of my previous articles, read it here. The SP1 Beta brings improvements to the feature by adding supportability to the scenarios that isn’t supported in the RTM version.
SP1 Beta brings the following enhancements.
- DAC mode support for two member DAGs that have one member in each datacenter.
- DAC mode support for DAGs that have all members deployed in a single AD site, including single AD site that has been extended to multiple locations.
