(Certain 6500 line cards share bandwidth, I believe, across multiple ports, so you might optimize actual server bandwidth by what servers connect to what ports and/or line cards. For the access switches, you might be most interested in load placed on uplinks (to determine whether channelling or 10 gig would be of benefit) and on server ports. Instead, you might want to measure bandwidth for all your ports.
Since a VLAN can span devices, and since you didn't describe your topology, there might be little benefit measuring VLAN bandwidth. Linking the main comms room to cabinets on different floors of the same building. The following are examples where a fibre optic cable could link together two separate locations. However, what is a fiber backbone and where is it used. You might also want to use a DFC on the line cards. A fibre optic backbone is a link between two different locations that are on the same network.
If your existing 37 switches are the "G" models, and you believe a single gig uplink is insufficent you can either channel up to 8 ports between the access switch and 6509, or for the 3750s, add a 3750-E to a 3750 stack and use a 10 gig uplink (this will require a 10 gig port card on the 6509).Īssuming the servers connect to the 6509 using gig links, you can maximize the bandwidth within the chassis by using a sup720 and using cef720 line cards (e.g. A 10 gig backbone would be a 10 gig circuit or circuits that tie together your top tier components.Īssuming you only have the one 6509 and servers and access switches connect to it, it's acting as your (collapsed) backbone (and can provide even more that 10 gig, internally).
