文件說:預設用單點即可.
A Windows NLB cluster can be configured in either unicast or multicast mode, where unicast is the default mode.
Unicast Mode
With the WNLB cluster configured in unicast mode, the MAC address of each server’s network adapter will be changed to a virtual cluster MAC address, which is the MAC address that will be used by all servers in the Windows NLB cluster. When unicast mode is enabled, clients can only connect to the servers using the cluster MAC address.
Multicast mode
With the Windows NLB cluster configured in multicast mode, a multicast MAC address is added to the cluster adapter of each server in the cluster. Note that I write “is added”, as each server will retain their original MAC addresses.
A Windows NLB cluster, no matter what mode it is configured in, works with just a single network adapter installed in each server, but it is recommended to install a second network adapter in each server, in order to achieve optimal performance, and to separate ordinary and cluster related network traffic.
So what mode should I use for my Exchange 2007 Client Access solution and how many network adapters should I install in each Client Access server? Well, best practice recommendations are to install two network adapters and use unicast mode, so that the host and cluster network traffic are each separated in their own respective network adapter
