hi John, I had read already about subnet manager but i don't really understand this, except when it's only configuration tool.
I assume it's not something that's critical in terms of bandwidth, it doesn't need nonstop bandwidth from the machine & switch is it? In case of a simple cluster consisting out of 1 switch with some nodes attached, is it really a problem?
