CCR的拓扑结构-->见下图: Majority Node Set Quorum with File Share Witness(FSW)
CCR支持两个节点的群集-->Arbitrator for 2 node
Majority of voters must participate in heartbeat
Specific considerations for cross-site CCR implementations-->Most common failure is Network between DC Locations
FSW located on HUB role within CMS 'preferred owner' DC-->This way network failure between sites does not affect Active node
Active & Passive communication failure - Active will remain Active-->SMB File Lock (Fast Failover)
CCR集群的安装步骤: 准备硬件和网络环境
安装和配置操作系统-->需要在Windows上安装特殊的补丁(KB 921181)
安装Exchange依赖的组件
配置网络
创建集群服务账号(需要特定的数据库加载访问权限)
创建并配置file share witness共享的权限
创建集群
添加第二个节点到集群中
配置MNS file share witness
检查和验证集群的运行情况
安装Exchange Server 2007邮箱服务器角色和集群邮箱服务
在第二个节点上安装Exchange Server 2007邮箱服务器角色
启用transport dumpster
验证集群的功能
创建并配置File Share Witness-->通常在Hub Transport上配置
验证集群工作情况: Run: Move-ClusteredMailboxServer 虚拟服务器名称-targetmachine: 被动节点的物理服务器名称-movecomment: "verifying CCR install"
Run: Get-ClusteredMailboxServerStatus 虚拟服务器名称
