I want to be sure something about sql server 2008 fail over clustering. I heard that when i set two sql servers as failover cluster servers i can set load level of sql servers. for examples i have SQL-A and SQL-B as failovered sql servers. SQL-A will process requests. SQL-B will wait. when SQL-A reached to %80 CPU load SQL-B will start to answer requests. Is that correct? this feature is sql server's feature or windows server's?
