Hi, What I understand from the documentation is that Active/Passive is a true failover solution. But there is like a resource waste as one server is just doing nothing when there is no failover. On the other hand, the active/active seems to be more money efficient as it makes use of the 2nd server. Each node must have two SQL2K instances installed. In case of failover, the remaining node takes the load of both SQL instances. And when both nodes are working, the server resources are shared by the two SQL2K instances. i.e. the active instance cannot use all the RAM of the server, because this RAM must be split and allocated at the time the SQL instance is installed. Q1. Is the summary above correct? Q2. What is the recommended approach for SQL2K Clustering? Thanks in advance.
