Hi guys,
I wonder if someone can explain me the difference between them.
My knowledge about the Switching capacity is that if we have a 48 Gig port switch, the switching capacity should at least be 48Gbps in the case of all port being used at full speed. It's the capacity to deal with all the bandwind in same time. Some switch under the 48Gbps capacity for a Gig switch are considered as blocking.
So if we take a stack of 8x4800 series, it says 384Gbps in fact sheet(8x48Gbps).
Where im lost is when a stack of 8x5500 series can go up to 640Gbps. Why the stack would need that much capacity if all the port together can only ask for 384 Gbps ?
Also, what's the meaning of Switch Fabric performance ?
And at last, if someone can tell me the switching capacity of a single 4550T, it's hard to find they always use the 4548GT to represent 4500 series. I found 320 Gbps for 8x4548GT. BTW it mean that those 4548GT can be considered as blocking ?
Thanks for your help !
