I have two Virtual Exchange Servers;
One on 1 Active Node and the other on the other node. The remaining two nodes are the passive nodes.
When verifying total memory usage I notice that 95% of the memory is used.
All these servers have 4GB memory. They have also been optimised by following the MS exchange optimisation KB article.
I am considering adding another 4GB per server. Will exchange access all of this memory or would I be wasting my time?
