Marvell Develops Gigabit Ethernet Platform

Marvell has introduced a Gigabit Ethernet switch platform designed for small-to-medium enterprises (SME) and businesses (SMB). Based on the Marvell Prestera range of packet processors and Marvell Alaska range of Gigabit transceivers, the Prestera 98DX3130 Ethernet switch and Alaska 88E1545 Gigabit Ethernet transceiver ICs are designed to make Gigabit-level performance more affordable by driving down network Ethernet switch power consumption as much as 70 per cent.

The platform also addresses the growing need in Ethernet networks to support rapidly escalating bandwidth requirements of multimedia content as the number of networked devices increases. The ICs reduce the energy bill for SMB/SMEs by using Marvell's advanced power-saving architecture to operate at less than half a watt per Gigabit port at maximum load. The devices deliver additional power reductions when network traffic is reduced or idle. Both the Prestera 98DX313x range of Ethernet switches and Alaska 88E154x range of Gigabit Ethernet transceivers support the emerging IEEE 802.3az Energy-Efficient Ethernet draft standard.

To increase network bandwidth and lower the operational cost of network management, the Prestera 98DX3130 Ethernet switch supports dedicated high-speed ports between Ethernet switches. Capable of operating with either optical or copper media, the high-speed ports can achieve up to 10Gbps connectivity without the costs traditionally associated with 10G links. Fast switch interconnects, also known as stacking, and embedded IPv6 capability reduce management overhead and network operating costs.

In addition to lowering the energy bill for SMB/SMEs, with this Ethernet switch platform Marvell took a system-level cost-reduction approach by reducing the bill of materials (BoM) needed for the devices. The same software is utilised across the entire product range, regardless of port and speed configuration. All products are compatible with the previous generation of Prestera 98DX3000 devices.
