Re: Max Devices on ethernet adapters

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Andy,

 FOr 80 PCs, dual GbE adaptors are overkill. I like duals but GbE units 
require dedicated IOPs adding even more cost. I have customers with i825 
and heavy SQL loads that don't tax a 100 Mb card.  I would Certainly do 
Dual 100Mb cards before I did a single GbE card.  Even the printers 
aren't really gonna put a hurt on the network.
