比较好的方案是 两台 WFE 和 两台 App server 并且在两台WFE之前要做NLB.

两台App server 可以出来 excel service 等。

No, that wouldn't make sense.  You load balance the WFEs so that users are sent to the WFE with lesser load at that time, and this keeps them in balance in terms of user load.  The app server is not browsed by users, so there's no reason to have it in rotation.  It also shouldn't have the web application service running anyway, so it can't be load balanced.  Btw, you don't load balance the servers themselves, but rather the services on them, which in this case are your content sites (web apps).

Later, you would not "cluster" app servers either.  The whole point of the service application model in 2010 is that the each place you start a "Manager services on server" for a given service app, SharePoint automatically load balances them - no load balancing mechanism needs to be added.  You don't install service apps on the other servers either, because that creates an entirely new instance of that service app.  Instead, you juse go to System Settings > Manage Services on Server, then start each relevant service on your app server.

You don't need to set up web apps on each server.  That's the whole idea on how it works.  You start the web application service on your new WFE, and then all web applications (except central admin) get replicated to that WFE.

PS. NLB is not very good, so it's recommended to use a hardware load balancer.  Yes, you should put each WFE in rotation, but app servers are not WFEs.

 

 

 

 

To compliment Clayton, please read what follows from http://blogs.msdn.com/spses/archive/2010/01/20/sharepoint-2010-shared-service-architecture-part-1.aspx , it means that if you started multiple instance of the same service application on different machine, SharePoint will handle with the built-in load balancer:

Redundancy Built-in

Multiple application servers can run a physical instance of the same Service Application. This is accomplished by running step 3 above on more than one application server. This provides redundancy in that requests from WFE’s pass through a built in load balancer to locate available application server running a physical instance.

For Example: Two application servers are running the same Excel Service application. If one application server goes down, the built-in load balancer will detect it and future request to Excel Service Application will be directed to application server that is still up and running with the associated physical instance.
