Flexible network topologies with any combination of SX, LX, or TX all in a 5U high package. Fast path Technology is the architecture employed in the HP Procurve Switch 4108GL that allows it to provide the highest performance in its class. Each connectivity module is a switch in and of itself, providing wire speed local switching. Traffic that originates and is destined for ports on the same module are switched at full media speed without going through the central switching fabric. HP has taken the concept of switch on a chip, and turned that concept into a high performance mini-chassis with a dynamically scalable switch fabric called the HP Procurve switch 4108gl.
