Marvell first to production with 10 and 40 GigE switch silicon for carrier networks and datacenters

SANTA CLARA, USA: Marvell, a leader in integrated silicon solutions, announced the mass production of its Prestera CX family of packet processors for broadband switching and datacenters. Hardware and software solutions based on the Prestera CX family are available from several equipment manufacturers and ODMs in the Marvell switching ecosystem including Accton, Aricent, Interface Masters, System Fabric Works, Vadatech and more.


The Prestera CX family is the first commercially available solution to offer up to 48 ports of 10 Gigabit Ethernet (GbE) on a single chip, and the first with multiple ports of 40GbE with line rate throughput.

These packet processors provide 480Gbps full duplex throughput for Carrier Ethernet, including Mac-in-Mac, Multiprotocol Label Switching (MPLS), Virtual Local Area Network (VLAN) Translation and IP Routing and can support up to 128K subscribers with a single device to meet the exponential growth of Internet traffic and massive deployments of high speed optical broadband networks.

The Prestera CX family's reduced XAUI (RXAUI) interface enables doubling of the switching capacity for current broadband access platforms while maintaining compatibility for legacy line cards, enabling in-field upgrade of access platforms as networks migrate to GPON and 10G EPON.

For Converged Enhanced Ethernet (CEE) networks in next generation datacenter deployments, the Prestera CX family offers a highly differentiated feature set including the industry's first commercially available 40GbE ports, Priority Flow Control and Fiber Channel over Ethernet (FCoE) capabilities including Fiber Channel Awareness and Fiber Channel Forwarding.

Multiple reference designs based on Prestera CX are available from Marvell, pre-loaded with software for enterprise and datacenter switching. These include a single rack unit 48 port 10G SFP+ solution as well as a modular 40 port 10G SFP+ solution with two ports of 40GbE uplinks.
