Data centers to drive Ethernet switch market in 2010

With the exception of Avaya, next-generation data center initiatives are driving the LAN switching market and its consolidation. And they are all intended to compete more intensely with Cisco, which owns 70% of the Ethernet switching market but still has an insatiable appetite for growth.

100G Ethernet: Bridge to Terabit Ethernet 

IT managers who are getting started with – or even pushing the limits of -- 10 Gigabit Ethernet in their LANs and data centers won't have to wait long for higher speed connectivity. 40 Gigabit and 100 Gigabit Ethernet products are slated to ship by year-end; terabit speeds are anticipated by 2015.

10G Ethernet shakes net design to the core 

Convergence, virtualization and more necessitates a new breed of high-performance, low-latency, non-blocking 10G Ethernet switches now hitting the market. And it won't be long before these 10G switches are upgraded to 40G and 100G Ethernet switches when those IEEE standards are ratified in mid-2010.

How to build a 100,000-port Ethernet switch

University of California at San Diego researchers have described software that they say could make data center networks massively scalable. The researchers say their PortLand software will enable Layer 2 data center network fabrics scalable to 100,000 ports and beyond, and they even have a prototype running at the school's Department of Computer Science and Engineering's Jacobs School of Engineering

Is it time to cut the Ethernet access cable?

A range of companies with wireless LANs are discovering that 50% to 90% or more of Ethernet ports now go unused, because Wi-Fi has become so prevalent.

Ethernet vs. Token-ring (Networking's 50 greatest arguments)

It was the classic IBM vs. Digital Equipment Corp. battle taken to the network theatre.

Fibre Channel over Ethernet: Hurry up and wait

Vendors at Interop say it's not driving the market for current data center projects. The market for FCoE is still in the gestation phase as standards are still fluid and pricing is too high.


Arista expands Gigabit Ethernet switch line

Arista Networks has unveiled a Gigabit Ethernet data center switch designed to better accommodate increasing traffic loads between the server access and core layers of the network.

Extreme upgrades Ethernet switch

Extreme Networks unveiled a Carrier Ethernet switch for smaller Tier 2 and 3 service providers.The BlackDiamond 20804 Ethernet Transport switch is the latest addition to Extreme's BlackDiamond 20800 series of Carrier Ethernet switches. Extreme rolled out the 8-slot BlackDiamond 20808 a year ago.

HP extends data center, campus Ethernet switches

The products include blade switches designed to reduce cost and improve security in the data center; an 8Gbps FibreChannel Virtual Connect module and firmware upgrade intended to tune bandwidth to application requirements; and new chassis and modules for its ProCurve 5400 and 8200 Ethernet switches to provide an array of configurations depending on network need.

Juniper's answer to Cisco in the data center: Project Stratus

Juniper's Stratus Project comprises six elements: a data center manager, storage, compute, Layer 4-7 switching, appliances and networking. It is intended to be a flat, non-blocking, lossless fabric supporting tens of thousands of Gigabit Ethernet ports, an order of magnitude reduction in latency, no single point of failure, and with security tightly integrated and virtualized.

NYSE taps Juniper for 10G Ethernet network 

Juniper Networks has landed perhaps its most significant enterprise customer to date, as the New York Stock Exchange plans to deploy hundreds of the company's switches for a time-sensitive, low-latency 10Gbps Ethernet network.

Fujitsu pumps out 10G Ethernet data center switch

Fujitsu has unveiled a 10Gbps Ethernet switch designed to handle important applications in an energy-efficient way. The XG2600 switch is a 26-port Layer 2 device that supports SFP+ optical modules and is designed for use with SFP+ twinax copper cables .The 1RU offering is the first Fujitsu Ethernet switch to support SFP+ connectors, which help the switch consume only five watts of power per port, Fujitsu says.

IBM adds 10G Ethernet switch to data center product line

IBM added 10 Gigabit Ethernet switches from longtime data center partner Voltaire to its roster of resold products. Traditionally a maker of Inifinband switches for the data center, Voltaire recently unveiled the Vantage 8500, a 10G Ethernet switch for converged data center fabrics. The Vantage 8500 is now generally available and customers can purchase it from IBM under this resale agreement between the companies.

Enterays revamps high-end Ethernet switch line 

Enterasys introduced a major upgrade to its Ethernet switch line in an effort to better serve converged networks, including those that are heavily virtualized. The S-Series boasts an almost fourfold increase in switching capacity and a 10x increase in throughput over the predecessor N-Series, plus greater 10G port density. In addition, the switches come with improved policy-based security features, a traditional Enterasys differentiator.

Cisco unveils data center blade switch 

The Nexus 4000 is the first blade switch in the Nexus line, which also includes the Nexus 7000 core switch, the 5000 top-of-rack switch, the 2000 fabric extender and the 1000V software-based virtual switch. The 4000 is intended to fit inside a blade server system enclosure and aggregate multiple 1G server NIC connections into a 10G pipe for connection to and from the Nexus 5000 and 7000 top-of-rack and core switches.

Nortel curtails carrier Ethernet/router investment 

Nortel said in March it was winding down its investment in Carrier Ethernet switch/routers (CESR) in favor of packet optical transport platforms.


Why industrial Ethernet is gaining momentum 

Process industries are trying to reduce plant downtime by deploying whole bunches of intelligent devices across their plants. These devices are expected to give the plant's operators better remote control over other automation components. They will deliver information about what's going on in the plant to business-level decision-making systems. They allow a larger plant to be managed by a smaller team. All of those devices have to communicate their data to the central management system using something, and the openness of Ethernet is compelling.

Terabit Ethernet in sight

Looking down the LAN road, the Terabit Ethernet milestone is very much in sight. While 3.2Tbps and 6.4Tbps speeds were demonstrated in test environments by Siemens/WorldCom and NEC/Nortel respectively starting in 2001, the first set of viable solutions are just now taking shape.


3Com's high-end switch: A fast, green alternative to Cisco

Our exclusive Clear Choice test of its new core switch backs up 3Com's claim that it has a viable high-end switch alternative to offerings from Cisco and others. This chassis-based, 288-port device delivered line-rate throughput in all performance tests, supported more Open Shortest Path First routing sessions than we've ever set up and consumed remarkably little power all the while.


Evolution of Ethernet 

From 3Mbps over shared coax to 40/100Gbps over fiber…and beyond. Here's a timeline showing key milestones in the growth of Ethernet.

Ethernet Everywhere! Few technologies in the world have proven to be as adaptable as Ethernet. Once a meek 3Mbps over shared coaxial cable technology used to connect printers and PCs, it has morphed to 100Gbps and is used to help run trains, planes and spaceships. Here's a look at some of Ethernet's cooler implementations.
