Conclusion
AlwaysOn Failover Cluster Instance
AlwaysOn Failover Cluster Instance provides instance level failover
Key Enhancements
• Multi-site clustering across subnets
• Flexible Failover Policy
• Improved system diagnostics
• Support for network attached storage (NAS) using SMB
• Support for tempdb on local drive
Multi-Site Clustering
AlwaysOn Failover Cluster Instance natively supports multi-site clustering without requiring V-LAN
Each site can have separate IP subnet
DNS entry updated to reflect current IP address on failover
Multi-site clustering provides protection from site failures
