Re: Speed between Switches & IDF MDF

said by xdxml12:

how do I know that these 1 gigabit inter-connections will support all the traffic between the switches without issues? What if the right speed that I should have used was 10 gigabit? How often is 10gigabit used to interconnect switches in the idf?

As aryoba noted, the only way you're going to know what speed you're going to need is to set up some sort
of detailed traffic / volume load analysis of what is needed now, and what may be needed in the future.
Understanding what the business requirements are from a latency, volume, reliability, etc view, and a toolset
like Netflow, Opnet, etc is needed.

As the old saying goes, "You can't manage what you can't measure."

Also, a trunk (etherchannel) will not increase the node-to-node throughput between switches. The src/dst (mac) are hashed to determine which link to use. Packets are not fragmented or interleaved -- there's no per-packet load balancing within a trunk.
