Help understanding IRF "stack" through-put
Hi guys and girls,
I'll try to explain this the best i can, but i've also drawn a little pic for you all (yay Art).
I have a core stack that consists of four HP A5500 EI switches that have dedicated stack ports/cables on the rear of the unit.
Each of these four switches has a aggregated port which connects to an edge switch.
My edge switches are HP1910-48g and do not have dedicated stack ports.
They have a feature called IRF that allows me to define which ports i want to use in a stack.
I'm having problems finding info of what data though-put a IRF port is capable of between the stack.
Looking at my pic below (dont laugh took me ages!). the switches on the left are my edge switches.... the switch on the right is my core stack.
If the edges switch are connect via a single irf cable (this is just a standard cat6 cable where the port has been configguired as a irf port) Am i right in thinking that the "Master" switch has a data through-put to the core of approx 4GBits, but the slave only 1Gbits because of the cable bottle neck?
i can add another 3 IRF ports to make a 4gbit link, but just wanted to know if a port is set as a IRF port its through-put is equl to the switches internal swich speed or capped @ 1Gbit.
I'm alittle confused.
