I've asked some weeks ago if it was better in a LTSP lab to use a switch or an HUB. Now I'm looking for a switch and a "technical" have tell me that a good switch is about 600€ this sound amazing... the one I've choose is a 3Com OfficeConnect dual speed 16ports. It's around 100/130€.
He told me that cheaper switchs like that, are not really switchs... and slow down connections... he talks about they have got two stacks... one for 10Mb (8 ports) another one for 100Mb (the other 8 ports)... not comunicating directly together., causing slowing down when a 10Mb port try to contact a 100Mb port. A good switch should be a Cisco... that have just one stack... "that make quikly the connections". And I've think that a good girlfriend should be Monica Bellucci ;-)
Maybe a Cisco switch is better than the 3Com I've choosed but is it really necessary?
He try to convince me that even if I've got a very good server, cables, fast ethernet on the clients if the switch is what him defines "a cheaper switch" all the stuff could work very bad.
He tells that the x protocols is not as fast as other protocols... is windows terminal services faster? :-) I've not asked this to him.
This sound a little bit amazing because in the lab I've tested at the school I work, the lab and NICs are 10/100 but there is an hub/switch... a device that is less smart that a switch isn't it?
I'm not an hardware guru, I just know the difference between an HUB and a switch and how a switch works. I've never heard about the think he talks about... someone can tell me if a switch like the one I've choosed will really slow down the LTSP lab? And more important, the think about the two stacks is true? Someone knows an internet document about that?
Thanks!
