and a little script that anybody can run to show that transfering
files on a network free of netbios is 5x faster but something
musta been wrong with the test script..etc.etc.. it can't be .. etc..etc..

some machines have 4 nics.. all going to the same nortel switch 
( same 1u box ) and connected via is stackable cable in the rear

some are channel bonded .. most are not

backups of 500GB during the day kills the network .. which it
does when it goes to the $150K 10-tape library thingie 
	which in itself should be on a separate tape lan

in my world, backups should be sorta invisible on the network,
and see if the disk latency is tolerable for head seeks
