Easily Unlock Data Center Leaf-Spine Architecture - Blog of FS.COM. As virtualization, cloud computing, and distributed cloud computing becomes more popular in the data center, a shift in the traditional three-tier networking model is taking place as well.
A new networking architecture, leaf-spine, which promises to overcome some of the limitations of the three-tier fabric and creates a fast, predictable, scalable, and efficient communication architecture in a data center environment is gradually become the mainstream in today’s data center deployment. Let’s take a close look at it in this article! Traditional Three-Tier Architecture A traditional three-tier network architecture, as shown in picture below, is composed of three layers.
The bottom of the architecture is the access layer, where hosts connect to the network. The middle layer is the aggregation layer, to which the access layer is redundantly connected.
Fiber Optic Transceivers Supported for Cisco Catalyst 3560-24TS Switch - Blog of FS.COM. Gigabit Ethernet, providing the speeds of 1000 Mbps, is able to boost performance while increasing the return on existing infrastructure investments.
The workers today are placing higher demands on networks, running multiple, concurrent applications. The Cisco Catalyst 3560 series switches provide a means to intelligently scale the network beyond 100 Mbps over existing Category 5 copper cabling and have SFP ports supporting different fiber optic transceivers to achieve optical transmission. Fiber Optic Solutions for Cisco C3KX-NM-10G Module - Blog of FS.COM.
SFP stands for “Small Form-factor Pluggable”.
SFP transceiver is used for Fast Ethernet applications. Switch with a Cisco C3KX-NM-1G module can support SFP. But with the increasing needs for higher data rates, 1 Gbps speed is not enough. 7 Times When You Should Just Say Thank You, But Don't. I don’t say “Thank You” as often as I should and I doubt I’m the only one.
In fact, I’m starting to believe that “Thank You” is the most under-appreciated and under-used phrase on the planet. It is appropriate in nearly any situation and it is a better response than most of the things we say. Let’s cover 7 common situations when we say all sorts of things, but should say “Thank You” instead. HP FlexFabric 5700 Switch Series Optics Options - Blog of FS.COM.

40G QSFP+ Optics Installation Guide. To install and remove the transceiver optics in a right way is very necessary to ensure the network to work stably and efficiently.
Today, we are going to introduce an installation guide of QSFP transceivers and DAC/AOC cables in 40G network. 40GbE QSFP+ Transceivers Overview 40 Gigabit Ethernet (40GbE) aggregation switches are becoming more common in today's data centers. At the heart of the 40GbE network layer is a pair of transceivers connected by a cable. The transceivers are plugged into either network servers or a variety of components including interface cards and switches and connected via the cables such as OM3 and OM4 for multimode application.
Who would be a Member of Parliament? - BBC News. More than 180 new MPs arrive at the Houses of Parliament for the first time this week.
What motivates them? Power? Glory? Pay and perks? Or might it be the principle of public service? When it was confirmed to David Cameron that he had won an overall majority at the election he made two speeches - one relatively private, the second very public. In the first, at a bouncing Conservative party headquarters he told his jubilant supporters: "The real reason to be excited is we are going to get the opportunity to serve our country again. " Guide to Multimode Fiber Cabling in 40/100G Migration - fiber optics. Nowadays one and 10 Gbqs data rates are not adequate to meet the continued requirement for expansion and scalability in the data center, thus technology evolves and standards are completed to define higher data rates such as 40/100G Ethernet.
In the meanwhile the cabling infrastructures installed today must provide scalability to accommodate the need for more bandwidth in support of future applications. OM3 and OM4 multimode cabling solutions have been proven to be a cost-effective solution for 40G data center. Today’s article will make you familiarize with this new Gigabit Ethernet and OM3/OM4 cabling to help you smoothly upgrade to 40G Ethernet. Multimode Fibers in Data Center. Who needs the House of Lords? Meet the peers rattling the Commons. It is late October in the House of Lords and the chamber is full.
The peers squeeze on to benches, or crowd four deep around the throne. The government has threatened to suspend the Lords, which is about to debate the abolition of tax credits. It is not the first time this House, which was last suspended by Oliver Cromwell, has faced an existential threat. You could say it is part of its remit. 40G AOC – A Shining Star in the Data Center - fiber optics. Recently 40GbE is gradually becoming the dominant Ethernet in the data center, which greatly promote the popularity of 40G components, especially 40G optical transceivers and 40G QSFP+ cables. 40G optical devices, featured by its unique specification, are designed to meet different interconnection applications in data center.
It is known that 40G copper direct attach cables (Copper DAC), 40G Active Optical Cables (AOCs) and 40GBASE-SR4 QSFP+ optics are used in data center to achieve 40G interconnection. But according to IHS (a research company), 40G AOC won larger market share than the other two solutions in 2015 and the trend will keep going in 2016.
So what makes it so popular in the data center? The following article will list several features of 40G AOC to give you a satisfying answer. Guide to 40 Gigabit Ethernet Cabling With MPO Technology - fiber optics. In the past decades, the network speed has a great leap from 10Mbit/s in 1983 to today’s 40/100 Gbit/s.

EU referendum: Tory MPs plot revolt in vote on 'purdah' rules - BBC News. Image copyright PA MPs are to debate planned changes to EU referendum campaign rules amid the prospect of a rebellion by Tory MPs. The government made concessions last week in a row over so-called "purdah" rules limiting the material ministers can publish in the run-up to the vote. Despite this, Eurosceptics remain worried the "Whitehall machine" may be used to help the pro-EU campaign. It comes amid reports that business leaders are being urged to tone down attacks on the risk of EU exit.
The Financial Times claimed Downing Street was privately advising pro-EU business figures to stop warning about the dangers of EU withdrawal for fear of undermining David Cameron's negotiating position.
