The new Dell servers all have raid 5 , so the drive array handles traffic much better than software raid based systems in my opinion. The unit shows nice trafic load with no load being seen on the consoles. Nice.
Feel the need for speed? We are testing the new turbo connection sporting 15 megabit down and two up. have to say with any share resource, speeds vary folks, period. With the net's design, not all servers have the same speeds and most have caps so that one person can not eat all the resources.
latency is not as good as I like, so we are working mesh now to handle BGP.
