May 01, 2013 11:30 AMArista Networks’ 7500E makes switches exciting again. New line cards support 10, 40 and 100GbE mix-and-match ports and offer outstanding port density. Arista’s per-port pricing is also compelling.
April 24, 2013 12:33 PMThe Nexus 6004 is a 10-Gpbs/40-Gbps data center switch. While a bit of a power hog vs. competitors’ boxes, it promises line rate forwarding on all ports, with 1-microsecond latency. I look at the architecture that makes this possible.
March 19, 2013 11:25 AMCisco Nexus 5500 port profiles let network engineers apply multiple port configurations with a single command. Port profiles can reduce errors and enforce standard configurations. We show you how with sample code.
February 01, 2013 04:18 PMI got a sneak peek of the Cisco Nexus 6000 switch series at Cisco Live. It's packed with 40-GbE ports, multicast support and solid core Ethernet capabilities that will translate into speed, simplicity and scale. The Nexus 6000 means Cisco finally "gets" cloud networking.
January 28, 2013 02:57 PMCisco Nexus Fabric Extenders (FEXs) provide ToR connectivity for Nexus 5000 and 7000 series switches. This 9-step plan shows you how to bring a FEX online, and includes configuration tips and code examples.
November 15, 2012 06:14 PMSoftware-defined networking (SDN) and OpenFlow aren’t the same thing. We’ll clarify the technical differences and discuss a more important distinction: SDN emphasizes applications that drive network usability and business requirements, while OpenFlow is a technology to link an SDN controller and network devices.
September 12, 2012 10:07 AMThe VDX 8770 is available in a 4- or 8-slot chassis switch that has a backplane, is designed to handle at least 4 Tbs per slot, and offers a new feature called Multi-Gateway L3 Forwarding. Learn more about the latest from Brocade.
May 08, 2012 11:03 AMThe company's new offering, the GS0072, supports 10 and 40 GbE. Find out why an expert says the new switch "has no other competitor."
March 16, 2012 11:00 AMNetwork equipment vendor Alcatel-Lucent Enterprise is introducing new switches and other feature enhancements to a collection of technologies it calls the “Application Fluency” network. This network platform recognizes the device seeking access to the network, authenticates a particular user and identifies the application they are running, and provides the appropriate degree of connectivity required. The company says these innovations are designed to enable enterprises to deliver cloud-based services.
January 30, 2012 09:00 AMThere are five configurations a network administrator should apply to a newly provisioned switch or router. Although application of these configurations may seem like common sense, 90% of devices I see are missing at least one of these settings, and about 75% are missing two or more. Use this checklist as an action item to verify your existing devices have these settings, at minimum, and integrate these in to any templates or provisioning documents you use. You'll appreciate the results of the consistency this adds to your network management and monitoring.
