    Bandwidth Question - What Size Pipe Needed?

    Hi all, quick question:

    750GB over the course of a month needs to be sent out to our servers...what size pipe do we need to sustain this?

    Burstable 100mbps line? T3? OC12?

    That is only a steady 2.26 Mb/s. You could easily push much more than that on a 10 Mb/s or 5 Mb/s or 3 Mb/s line..

    I agree with lumbyjj, unless you feel that there will be large bandwidth spikes on a consistent basis due to the rolling out of new content or something of the sort...

    The size of a pipe is easy to answer but the bigger question is through-put and not total BW per month. A major misconseption is that if you have enough BW per month you are ok. Not so at all.

    BW should be measured per second and not per month. If you get a major spike in BW for 1 minute in the month the pipe will "bottle neck" and will probably cause problems. You need BW "overhead" to make sure that enough Bytes per second can get through.

    Think of a pipe as a highway. Rush hour traffic takes more lanes of road than mid-afternoon cruising..
