Marvell Prestera Means Better Data Center Ethernet

March 14, 2017

Data centers are, these days, an almost indispensable part of everyday life. Not only do these systems keep our data for everything from bank operations to email access and beyond, but these also allow a lot of peripheral systems, like power grids and the like, to carry on. That requires some potent Ethernet access as well, and recently, Marvell brought out its new Prestera PX line to help drive Ethernet access at the data center level.


With the new Prestera PX Passive Intelligent Port Extender (PIPE) system, data centers have a great new opportunity to not only get the Ethernet access needed for everyday operations, but to get it in at a lower cost as well. While bandwidth needs are only on the rise, data centers have been faced with the unique—and often frustrating—challenge of providing those needs, and beyond, while doing so at significantly lower costs.  The Prestera PX system, meanwhile, offers new tools to help meet that seemingly impossible challenge.

New with the Prestera PX is support for the IEEE 802.1BR standard, which provides a complete and novel solution that allows for top of rack (ToR) switches to be used, but pulling half the electricity they used to. That also means reduced costs, as anyone who's paid a power bill lately knows full well.

Marvell's vice president and general manager of the networking group Michael Zimmerman commented, “Our Prestera PX family is a purpose-built portfolio of port extenders that attaches to high-density 100GbE switches, offering tremendous cost and power benefits. In addition, our PIPE solution doesn't need application software, simplifying the network layers and offering massive savings in both CAPEX and OPEX.”

With less demanding Ethernet switches now in place, it allows for better access to an increasing range of port speeds, as 10 GbE switches often become 25 GbE, and 40 GbE switches become 100 GbE. With the Marvell systems, current data centers are better able to scale up as need be since the less power-hungry switches mean that more such switches can be put into play for the same power demand. That's good news for the data center, and by extension, all its users. Said users mean a big potential market afoot and a potentially great windfall for Marvell.

Data center demand won't be slowing up anytime soon, and that means that ways to make the current data center better will likewise be in heavy demand. Marvell's systems should provide for better Ethernet access at the data center level, and that could be a big success to come for Marvell.
