Marvell has brought to market a programmable switch optimised for 24 and 48 ports of 2.5 Gigabit Ethernet (GbE), and has dedicated 10GbE and 40GbE uplinks and stacking ports. The Prestera 98DX325x delivers wire speed packet processing bandwidth of 168Gb/s in an optimised and compact footprint.

Coupled with Marvell’s 88E2040 quad NBASE-T physical layer devices (PHYs), the Prestera 98DX325x offers a cost-effective way to support the convergence of the wired and wireless network while utilising already deployed CAT5e Ethernet cabling and infrastructure to migrate from 1GbE Copper to 2.5GbE copper.

The 98DX325x can be implemented in various applications including 802.11ac Access Point uplinks, switches, servers, workstations and high-end PCs. Additionally, with the 98DX325x, Marvell now brings software-defined networking (SDN) and switch abstraction interface (SAI) to 2.5GbE campus environments enabling private cloud deployments with a full software stack turnkey solution.

The Prestera 98DX325x switch packs 48 ports of 1GbE with four ports of 10GbE uplinks and two ports of 40GbE stacking for standard Enterprise and SMB/SME access deployments, and up to 24 ports of 2.5GbE with 10GbE and 40GbE uplink and stacking for large wireless campus deployments. It offers support for virtual bridging and routing and congestion management features enabling software-defined networking (SDN)/network function virtualization (NFV) cloud-managed network deployments.

In addition, the devices promise to deliver advanced virtual overlay networking offering support for NVGRE, VXLAN-GPE, NSH, GENEVE, Shortest Path Bridging (SPB), TRILL and GRE. The switch is server virtualisation compliant with IEEE 802.1Qbg EVB, 802.1BR Port Extender and supports IEEE 1588 1-step timing for precision timing applications.

The devices are available for sampling.
