PRESTERA

Marvell's purpose-built port extender solution

Prestera PX

The Marvell® Prestera® 98PX1012 is a purpose-built port extender device leveraging the industry standard IEEE 802.1BR.  Termed PIPE, these passive intelligent port extenders offer a modular approach and an optimized solution to enabling a diversity of port densities and speeds, the 98PX1012 allows customers to easily adapt to various port speeds through multiple configurations.  

While existing solutions are designed with a generic switch device that is scaled down to a port extender device, the 98DX1012 is optimized in terms of power, cost and simplification to meet the port-extender requirements.

Marvell’s Prestera PX family also introduces innovative ways to reduce Top-of-Rack (ToR) port configurations by replacing a switch with PIPE devices. This in turn saves power and lowers the cost of maintaining and upgrading systems.
