2 sunucuda failover cluster senaryosunda "DC" nasıl konumlandırılabilir

The servers for a failover cluster must run the same version of Windows Server 2008, including the same hardware version (32-bit, x64-based, or Itanium architecture-based). They should also have the same software updates (patches) and service packs.

You will need the following network infrastructure for a failover cluster, and an administrative account with the following domain permissions:

• Network settings and IP addresses: When you use identical network adapters for a network, also use identical communication settings on those adapters (for example, Speed, Duplex Mode, Flow Control, and Media Type). Also, compare the settings between the network adapter and the switch it connects to and make sure that no settings are in conflict.
  
  If you have private networks that are not routed to the rest of your network infrastructure, ensure that each of these private networks uses a unique subnet. This is necessary even if you give each network adapter a unique IP address. For example, if you have a cluster node in a central office that uses one physical network, and another node in a branch office that uses a separate physical network, do not specify 10.0.0.0/24 for both networks, even if you give each adapter a unique IP address.
  
  For more information about the network adapters, see Hardware requirements for a failover cluster, earlier in this guide.
  
  


• DNS: The servers in the cluster must be using Domain Name System (DNS) for name resolution. The DNS dynamic update protocol can be used.
  
  


• Domain role: All servers in the cluster must be in the same Active Directory domain. As a best practice, all clustered servers should have the same domain role (either member server or domain controller). The recommended role is member server.
  
  


• Account for administering the cluster: When you first create a cluster or add servers to it, you must be logged on to the domain with an account that has administrator rights and permissions on all servers in that cluster. The account does not need to be a Domain Admins account, but can be a Domain Users account that is in the Administrators group on each clustered server. In addition, if the account is not a Domain Admins account, the account (or the group that the account is a member of) must be given the Create Computer Objects and Read All Properties permissions in the domain.
