marvell prestera 98dx3336/3236 next-generation packet processor for carrier, industrial, campus, smb/sme access switching applications product overview the marvell? prestera? 98dx333x and marvell prestera 98dx323x series of devices are a new generation of highly integrated, high-performance and low-power packet processors that enable intelligent switching, security and performance at the access/ edge of next-generation networks. the marvell prestera dx3300-based systems enable feature-rich and secure gbe and 10gbe access networking platforms for campus, industrial and carrier networks. armed with dual-core on-chip arm cpus, the marvell prestera dx3300 family of devices is capable of meeting demanding yet cost-sensitive performance needs by enabling host management and embedding additional value-added security or monitoring applications. native integration of phys enables direct-attached copper or fber-based 10gbe network connections, as well as multi-system stacking. support for the ieee 802.1br tunneling schemes enables centralized management architectures and a port extender model of deployment. the marvell prestera dx3200 family of devices continues to address the needs of cost-sensitive gigabit ethernet access for unmanaged and intelligent access networking solutions by providing an extremely power-effcient design, without compromising on the full complement of features needed in such networks. the new marvell prestera dx devices support an aggregate bandwidth of up to 84gbps and offer 10g/20g ports for uplinks, stacking or cascading. two devices can be cascaded to build non-blocking 48 x gbe + 4 x 10gbe or 48 x gbe + 2 x 10gbe + 2 x 20gbe switch systems. 24*gbe + 4*1gbe 24*gbe + 4*10gbe 24*gbe + 2*10gbe + 2*20g stacking sgmii / qsgmii / sfp+ ? ? ? ? ? ? ? ? ? pcie ddr3 serial flash usb network shield ingress policers secure control multicast egress policers ingress policy packet bu?er memory egress policy transmit queues & shapers bridge ipv4 / ipv6 routing 800mhz armv7 2-core cpu network / interface ports fig 1. marvell prestera 98dx3336 device block diagram packet processors
