I agree. It is a bit strange of a value. That's the way the cluster
was when I got hired, so I assume there's a reason. I'm just still
trying to figure what the reason is. The hosts will do whatever you
tell them, and the switches in question support anything from 594 to
9252, at least according to their documentation.
The problem is that we've had a lot of staff turn over in the last year.
None of us were here when the system was first built about a year and a
half ago. We're still figuring a lot of this stuff out.
Seems to work, though, so for now, I'll leave well enough alone.
