  Hi,

we are having 4510R+E , now with 1 gigabit uplink want to go for 10 gigabit uplink

what are the benfits of 10/100/1000 with 10g uplink against if we buy 10/100 with 1g uplink. kindly suggest some models of both

regards

rajat

Whenever you increase edge bandwidth, i.e. moving from 10/100 to 10/100/1000, it should take less time to transfer the same amount of data.  Having an uplink faster than the edge allows multiple concurrent edge transfers without congestion; it also reduces serialization latency.  However, if you don't commonly have multiple edge transfers, and serialization latency isn't adverse, you might find you don't benefit as much from increasing uplink 10x, especially if Etherchanneling is an option.  Also remember, increasing edge bandwidth 10x doesn't mean there's also a 10x increase in actual data transferred. In other words, as you increase edge bandwidth from 10 to 100 to 1000, you might find you don't need to increase uplink bandwidth in the same ratios.

Thanks a lot joseph,

if we move 1 gigabit uplinkhaving backplane 6gbps  to 10gigabit uplink but backplane is 48gbps how much performance speed will improve do you have any mathematical calculation.please suggest best 10g uplink switch without poe

I presume you haven't heard of the 6500E and the Sup2T with 80 Gbps backplane and ability to support 40 Gbps.

Hi leolaohoo

thanks for your kind knowledge sharing but i have limitation that ihave hardware platform of 4510R+E instead of 6500E. so, waiting your reply as my above query.

You might be mixing "apples and oranges".  The 6 Gbps backplane is the limitation bandwidth to original 4500 card slots, not a limitation to uplinks on supervisor itself.  (For example, the SupV-10ge can drive both 10 gig links at wire-speed.)  The 48 Gbps backplane is available with the Sup7 and 48 Mbps line cards.

Assuming most your bandwidth usage will be "north-south" (i.e. to/from uplink), the uplink(s) become the principle bottleneck.  For such, the SupV-10ge might be as effective as a Sup6 or Sup7 variant.  The Sup6/7 variants are better if you need more bandwidth between line cards or need 10 or 20 gig to supervisor to/from and individual line card.
