Merant Sequelink install client side or server side


We were planning to have two separate machine and run wM IS/TN on one and TN database on other. Which box on wM or DB shoud one install Merant Sequel Link for performance purposes and architecture wise. Also we may go for clustered environment in future, so does wM licence provided SequelLink is cluster aware or what u guys suggest for clustering, install merant on all wM clients.
