    Stacking: Backplane or uplinks?

    I have recently been told by a supplier that stacking switches using a backplane is old-hat and that the current practice is to stack using the Gig uplinks.

    Is this true, and if you were installing a new network which would you choose?

    I know that the HP 2650's only have gig and mini gbic ports for this.

    Here's a whitepaper on how HP Procurves do it:

    Pratically though, what I have here is a mix. Some switches are stacked using GigE or fibre. However, several of the 3com units are stacked using 3coms proprietary backplane system.

    Re: Stacking: Backplane or uplinks?

    It depends on the switches you have really. For example D-Link are moving away from the old 'chasis' type switch and favouring their Xstack style of product - these use a proprietory backplane.

    Personally, I use HP 2650's with fibre uplinks to the core switch and the switches are stacked for easy management.

    The question that is important is 'do I need super speedy backplane speeds or will standard uplinks to a core be suitable'. Everyone has different requirements.

    Re: Stacking: Backplane or uplinks?

    all my 3com switches are stacked, can some one explain to me what the term 'backplane' means?

    Take a look at http://en.wikipedia.org/wiki/Backplane, it doesn't specifically mention networking but it covers it in general.
