D-Link 10-Gigabit Ethernet

Standardized Solutions for Maximizing Bandwidth and

Enabling Storage and Computing Technologies

White Paper

July, 2007

Abstract

Bandwidth intensive applications, VoIP, OS virtualization, cluster computing, video and audio proliferation, and high-performance back-up

solutions are all driving the charge for higher capacity networking. There’s also a push to simplify networks and reduce connectivity costs

– all while maintaining reliability and decreasing latency. Fortunately, network bandwidth doubles approximately every two years. Gigabit

Ethernet, for example, is now maturing and making way for 10Gigabit Ethernet (also referred to as 10GbE or IEEE 802.3ae), which was

introduced in 2002.

10GbE, which increases capacity by a factor of 10 over Gigabit Ethernet, easily connects to existing Ethernet equipment, enables network/

server consolidation and clustering virtualization, and offers copper technology speciﬁ cally designed for upgrading short-range links.

A 10GbE solution is particularly compelling in SAN/NAS disaster recovery and business continuity environments, where expensive Fiber

Channel links can be replaced while unifying the entire network on Ethernet.

10GbE and iSCSI technology can act as high-speed trunk lines where multiple GbE clients access the SAN, for example – supporting disaster

recovery and business continuity initiatives. In departmental scenarios, this option is a very compelling alternative to Fibre Channel switches.

Existing Ethernet skill sets ensure that training and implementation costs are minimized. There is no additional technology to learn and no

new expertise necessary.

This white paper explains 10GbE solutions for ﬁ ber optic links as well as copper, summarizes market drivers, examines some of the more

common applications, and details D-Link’s new low-cost 10GbE local area and wide area solutions.
