We have one HP Procurve 3800 acting as a backbone and seven 2920 used as "branch" switches.
All 2920s connected to the 3800, each one with one CAT6, and this actually gives us only 1 GB link between the "branch" switches and the backbone and also creates single point of failure if the port dies.
On 2920s we already have stacking modules allowing us to stack up to 4 switches in one stack.
It is impossible to stack different types of switches together
What would be the best setup to achieve the best possible performance of these switches?
