Stackable Switches - why is it better?
When we redesign our infastructure during the summer, one of the things I am inclined to include is a stack of "stackable" switches (3x 48port), as opposed to the current setup of a single copper link between them. Does having stackable features differ significantly, and are they worth the extra money? I know they are easily managed by single IP in the management interface, but what else is desirable?
For instance, the Netgear stackable (using GS748TS as an example) has HDMI connections at the rear which I believe can provide around 20gbps throughput between switches, which of course is significantly more than single copper links.
On the other hand, I have been looking into some HP switches to do the same job (on a budget), so noticed the Procurve 2810 series include "virtual" stack ability within them. How does a physical stack with the NG compare with the "virtual" stack as described in the HPs? Can the high throughput between switches be achieved on the HP as well as the NG? If anyone has this model of HP switch or knows of them, how does the stack work (ie: just copper links or is there special connectivity).
