I'm watching the Server+ videos and I did not see any coverage on memory "Ranks" and memory channels. Can someone explain these concepts and what you need to understand when purchasing memory for servers.
For example, I have a choice of purchasing sticks that are 1x16GB SINGLE Rank or 1x16GB DUAL Rank.
-
What are the pro's and con's of each?
-
When should I choose one over the other?
-
Does the amount of memory channels affect the decision?
