We are planning to setup a Teaming 2.1 server for 500 users ( about 30-40% of simultaneous connected users) in a High-availability environment.

May I know how we size the hardware?

2 Server with Teaming and MySQL ?

We are thinking to Clustered both Tomcat, Lucene and also MySQL.

But MySQL database script is in InnoDB, which is not supported in MySQL Cluster. Any idea?
