HP answer to a full redundant network with fully used uplinks

When does HP gonna have a solution so you can have a redundant network without Spanning-Tree setting one uplink in-active so you have two uplinks active and bundled??

Like 3COM have with there XRN and Cisco with the 3750 switches?

Re: HP answer to a full redundant network with fully used uplinks

Which platform are you talking about? If you are working with the 9300 series switches, you do have this functionality--if I read you thread clearly.

So you want a "backplane stacking" capability in the ProCurve stackable switches - is that it?

If that is the case - the 4100gl and 5300xl series products do that today seeing they are modular mini-chassis products at stackable pricing.

Re: HP answer to a full redundant network with fully used uplinks

When you need redundant networks you will have two core switches and maybe in different server rooms.

So your edge switch will have an two fiber uplinks to each core-switch (5300xl or 9300).
One uplink will be inactive because of spanning tree. With 3COM XRN for example you can have two separate coreswitches connected so they serve you uplink trough both fibers.

More and more customers want to fully use there expensive fiber.

Re: HP answer to a full redundant network with fully used uplinks

If you use the 5300xl as and edge switch you can have multiple links trunked together or use multi instance spanning tree to have redundant links to the core all active.

With the new free update coming for the 2600's and 2800's to support multi instance spanning tree in late Oct, this will do the same thing as 3com and Cisco, but using industry standards instead.

Re: HP answer to a full redundant network with fully used uplinks

So with MSTP you can have the 2 fiber uplinks active, each one to a separate core switch.
So the uplink will be 2GB (4GB full duplex).

I don't really see how MSTP will do this job?
There also should be some kind of loadbalacing etc....

We use Meshing for this - it supports traffic on both uplinks, i.e. one TCP session can only use on link.

(5300xl)

Meshing works indeed but only between 5300xl.

Most edge switches I install are 26xx.

Re: HP answer to a full redundant network with fully used uplinks

How would you provide a full redundant network with both active uplinks with ProCurve equipment?

Note: Both Core-switches are in different locations !!
What connections would you need between the coreswitches, bandwith etc....??

let's say we have about a maximum of 500 end users
