    SQL Server software can be configured so that if one server fails, its processing will be picked up, recovered
    and  continued  by  another  server.  All  editions  of  SQL  Server  2012  provide  basic  high  availability  features
    including backup log shipping, database mirroring and two-node failover clustering. Advanced (AlwaysOn)
    high availability features in SQL Server 2012 Enterprise Edition include enhanced support for multiple, active
    (readable) secondary servers and support for multi-site failover clustering.

  • Only one license for db mirroring? Mirroring is db level and partner server can have non-mirrored db, unless you mirror all dbs and can guarantee to failover them at same time.

  • 看起來AlwaysOn也是Cluster技術的延伸,所以授權應該是要兩台沒錯的,謝謝大家了!
