Understanding Access Points (Names and IP Addresses) in a Failover Cluster
Applies To: Windows Server 2008 R2
An access point is a name and associated IP address information. You use an access point to administer a failover cluster or to communicate with a service or application in the cluster. One access point can include one or more IP addresses, which can be IPv6 addresses, IPv4 addresses supplied through DHCP, or static IPv4 addresses.
When selecting a network to be used for an access point, avoid any network that is used for iSCSI. Configure networks used for iSCSI so that they are not used for network communication in the cluster.
