1887.0. "Ethernet to FDDI Performance Gain with Q-Bus?" by TROOA::MCCHARLES () Thu Nov 30 1995 16:44

    
    One of our customer's is considering changing the Ethernet cards in his
    two Vax 400 Model 500a to DEFQA-SF FDDI cards.  Given the performance
    limitation of the Q-Bus, is it worth the investment?  What kind of
    throughput improvement would be expected?
    
    Thanks

1887.1		STRWRS::KOCH_P	It never hurts to ask...	`Thu Nov 30 1995 18:41`	4
	Absolutely NOT. the DEFQA has a thruput of 13Mbps. It's better to put 2 Ethernet controllers in with a PEswitch 900TX than to put in the DEFQA. The customer won't be pleased with the performance.
1887.2	Thanks, that's what I suspected.	TROOA::MCCHARLES		`Fri Dec 01 1995 12:21`	1
