I wonder why you need a managed switch?

Our cluster has one managed switch and one un-managed.  It isn't big 
but from what I read before, management can slow down throughput.  As 
I was limited to one manufacturer (political) I chose the switch with 
the fastest throughput.  No managed switch was rated as fast as the 
unmanaged switch.

Our local supplier has a 3 year warranty as well.  Rackmount cases and 
such.  We ended up with an extra machine due to savings from not 
dealing with a major supplier.
