总结
通过上面的步骤演示,在搭建AD DS服务的时候有一些地方是需要注意的,希望大家能够看清楚截图,一步一步进行配置,基本上就没有问题了
现在AlwaysOn可用性组已经完全支持 Windows Azure ,可以把辅助副本部署到 Windows Azure 上
希望通过这篇文章让大家体会到新一代高可用技术AlwaysOn的强大,下一篇是安装并设置故障转移集群
至于Windows Server 的AD 域服务的问题可以参考《Windows Server2012系统配置指南》这本书

希望台湾MVP 戴有炜老师的丰富Windows Server方面的知识能给大家带来更多帮助
操作系统的注意事项,硬件配置、软件配置、故障转移集群都在上面两本书有介绍

AlwaysON – HADRON Learning Series: – How does AlwaysON Process a Synchronous Commit Request

Is this safe for SQL Server?
The answer is yes. An I/O subsystem can return a larger sector size than actual, physical sector size as long as all reported values can be evenly divided by 512 bytes.
4096的块只要能被512整除就无问题
As the diagram below shows, SQL Server maintains parity on 512 byte boundaries, for the log, regardless of the reported sector size. This allows SQL Server to detect a partial write (torn behavior.) For example, if the system reported a sector size of 4K but the physical sector size was 512 bytes, the I/O subsystem is only guaranteed to flush to a 512 byte mark. If the first 4, physical sectors are flushed (2K of the 4K aligned block) and a power outage occurs, SQL Server will be able to detect the entire 4K was not properly flushed.
