Cisco Injects New Life Into Catalyst 6500 Switch

Posted on by Posted in Career, CCIE, CCNA, CCNP, Cisco, Tech

Cisco Tuesday took dead aim at HP and its own shrinking profit margins by introducing a major refresh to its venerable Catalyst 6500 Ethernet switching platform.

The company announced at Cisco Live in Las Vegas the Supervisor 2T engine for the 10-year-old Catalyst 6500, which delivers 2 Terabits of bandwidth to the system. This is almost three times the scale of the previous Supervisor 720, and like with that offering, 2T bandwidth can be doubled when configured into what Cisco calls a Virtual Switching System.

Cisco also announced a new generation of 10G line cards for the Sup 2T and didn’t mince words when describing the system’s purpose: to marginalize competitive offerings from Brocade, Juniper and most significantly HP, which has been gaining share on Cisco of late with lower cost platforms.

NINE LIVES: Catalyst 6500 has another decade or more left, Cisco hints

“We reject ‘good enough’ networks” which are marketed mostly on low price and drive commoditization, says John MCool, senior vice president and general management of Cisco’s Core Technology Group.  “Our market share has hovered around 70%, or 50% of intelligent ports. We’ve been able to maintain share, and grow our core share, by delivering value to our customers.”

At $38,000, the Sup 2T is priced at one-third that of HP’s A9508 switch yet is 3X the performance and supports 200+ features or services, claims Scott Gainey, Cisco director of marketing for Unified Access Solutions. Cisco says it also almost doubles the amount HP spends on R&D — $5.3 billion vs. $3 billion — even though Cisco is half HP’s size in terms of revenue.

HP, citing data from Dell’Oro Group, says it captured 12% of total worldwide Ethernet switching revenue market share in Q1, up 2.5 percentage points year-over- year.  Cisco’s share fell 5.8 points in the same period, HP claims.

But Cisco is also facing a troublesome switching product transition in which the high margin Catalyst 6500 is being squeezed by the lower margin, higher performing Nexus 7000 line. This is lowering switching profits for Cisco, which doesn’t sit well with the company or Wall Street.

So the introduction of the Sup 2T may be a way for Cisco to maintain Catalyst margins in the face of the Nexus transition; or it may indicate that a large swath of the Catalyst 6500 base, especially in the enterprise campus, is resisting the migration to the Nexus.

McCool, however, says it’s simply a case where the market is “bifurcating” into separate requirements for the enterprise campus vs. the data center.

Cisco will be leaner, faster, more attentive, Chambers pledges

Discusses streamlining during keynote but dodges huge layoff expected

LAS VEGAS — Cisco CEO John Chambers briefly addressed the company’s current challenges, restructuring and imminent layoffs during his keynote address at this week’s Cisco Live customer conference.

Best CCNA Training and CCNA Certification at Certkingdom.com

Cisco may shed 5,000 and perhaps up to 10,000 positions early in its fiscal year 2012, which begins in August. The company is looking to cut $1 billion in expenses and dump unproductive or non-core product operations after consecutive quarters of uninspiring performance.

Cisco has lost share and profits in switching, and its foray into consumer electronics has been disappointing. Many blame ambitious incursions into adjacent markets through 145 acquisitions over two decades, which distracted the company from its core routing and switching business, as well as a bloated management structure that stalled decision making.

Chambers promised the audience changes.

“We are continuing to reinvent ourselves,” he said during his address. “We are looking at how to streamline to move a bit faster in the future. We were too complex (in innovation). We are making changes to move at a faster pace.”

The changes will help Cisco innovate faster, Chambers said. That means new products should get into the hands of customers faster. He also promised a Cisco that’s easier to do business with and more attentive to customers.

Cisco has come under fire recently for being heavy handed in customer relations.

“You ask, we deliver,” Chambers told the customer-heavy audience of 15,000. “We’ve got to be easier to do business with, include you in driving our product direction, share our roadmaps, have an easy to use product portfolio. But innovation is the buzzword on where we’re going to go.”

In the past six months, Cisco announced 85 new products. But it also streamlined its operations and re-focused the company on five core areas of product development: Routing, Switching, Security and Services; Video; Collaboration; Data Center/Virtualization/Cloud; and Architectures.

Routing and switching is the bedrock of the company but, why these five?

“Collaboration will be the driver of productivity,” Chambers said. “Data center/virtualization/cloud is the most network-centric architecture. Architectures are the way you tie products together. And video is the next voice.”

Chambers said there are 20 million meetings per month hosted on Cisco’s WebEx application, and that the company is “putting video into everything we do architecturally.”

Cisco adds tools to scale wide-area video

The ECDS platform is designed to make live and on-demand enterprise video more efficient

Cisco Systems continued to build its enterprise video infrastructure on Thursday with the ECDS (Enterprise Content Delivery System), a software-hardware platform to ease video management and make distribution of video to remote locations more efficient.


Best CCNA Training and CCNA Certification at Certkingdom.com

ECDS is part of Cisco’s overall Medianet architecture, designed to automate many aspects of producing and delivering video for employees, partners and customers. The company has been fleshing out this vision since 2006 with an eye to supporting new work styles and the growing network demands that come with them.

BACKGROUND: Cisco fleshes out its business video plan

The purpose of ECDS is to help enterprises distribute both live and on-demand video to large numbers of sites and users. It can be used to support dozens or thousands of users, in thousands of locations, according to Cisco. For example, the system can send live video to a branch office in one stream and then split it at that location into a single stream for each of 10 users there. This removes the need to send 10 streams across an expensive WAN (wide-area network) link, Cisco said.

ECDS consists of software that can be run on one of two new appliances, the Media Delivery Engine 3100 and 1100, or on a virtual blade on a Cisco WAAS (Wide Area Application Services) platform. The MDE 3100 can scale up to 5,000 concurrent users, the MDE 1100 to 500 users, and the MDE 50WVB to 200 users.

Part of the purpose of ECDS is to minimize the impact of video on an enterprise’s network, to tamp down the cost of expanding video use across an organization. It incorporates Cisco’s WAAS application acceleration software and provides caching capability. For example, companies can distribute pre-recorded video during off-peak hours if it doesn’t have to be viewed immediately, Cisco said. ECDS can also provide on-demand caching, which sets aside a local copy of a video the first time it’s viewed at a location, to prevent it having to be downloaded over the WAN on subsequent viewings.

In addition to handling many different video applications from Cisco and other companies, the platform works with multiple formats, including H.264, Flash and Windows Media. It also can be used in distributing video to third-party clients, including tablets and mobile devices.

Many enterprises have several forms of video on disparate systems that they want to consolidate, according to Forrester Research analyst Henry Dewing. For example, they may have an archive of training videos, a videoconferencing system for executives and another set of video offerings for customers. Those may all run on separate systems from different vendors, he said. Cisco’s enterprise video portfolio, the broadest of any vendor, appeals to some of those organizations, Dewing said.

What Cisco still doesn’t have is sophisticated video editing capability and an easy-to-use management interface, Dewing said. Editing capability integrated into the network was part of Cisco’s original vision for Medianet, but what it has provided so far is fairly simple, he said. Given the narrowing of Cisco’s focus to core products, which has already led to the demise of the Flip camcorder, the company may step back from trying to compete in a field already full of editing tools, Dewing said. User interfaces are a longtime issue for Cisco, he added. “They’re getting there, but they’re still no Apple,” Dewing said.

Facebook fires back at Google+ challenge

Facebook responds to Google’s Hangouts with Skype-fueled video calls

A little more than a week after Google unveiled its own social network , Facebook responded today with upgrades to its site, in an attempt to curb growing enthusiasm for the Google+ project.


Best CCNA Training and CCNA Certification at Certkingdom.com

After teasing last week that today’s announcement was going to be ” awesome ,” Facebook co-founder Mark Zuckerberg took the wraps off a partnership with Skype that brings video chat to the social network. The news also came with the unveiling of a new group chat feature for the site.

The announcement seem to take a swing directly at Google+ , which opened with a “Hangouts” feature that is similar to an online group conference call. Facebook’s response to that is to work with Skype for its own group call feature.

That, say industry analysts, is a sign that Google+ may be sufficiently compelling to have Facebook glancing a bit nervously over its shoulder.

“The Skype deal isn’t something they cobbled together in a week, but Google’s announcement might have accelerated this a bit,” said Michael Gartenberg, an analyst with Gartner. “I don’t think this takes the wind out of the sails of Google+. They’re kind of different experiences.”

Dan Olds, an analyst with The Gabriel Consulting Group, said Facebook just might have succeeded in taking some of the luster off Google+.

“This is Facebook both responding to Google’s announcement and pointing out to the market that Facebook has at least a 749-million user lead over Google+,” Olds said. “And Facebook also is signaling that they aren’t going to stand still and watch Google+ come on. So, yah, they are taking away some of Google’s momentum.”

While Google and Facebook have been competitors over the past year, Google’s introduction of its own social network raises the stakes to a new level.

And that is where Microsoft comes into the mix.

Microsoft and Facebook have been partners for several years, and Microsoft bought an early stake in the social network in 2007. That was a fortuitous move, which has made Microsoft and its partner Facebook common enemies of Google. They can work together to battle Google, and the Facebook/Skype deal is proof of it.

In May, Microsoft agreed to acquire Skype for $8.5 billion. While the deal hasn’t closed, upon news of the upcoming buy, there was immediate speculation that Facebook would benefit from it.

“We are going to see Facebook work with partners to try to circle the wagons against Google,” said Gartenberg. “It does become a little of the enemy of my enemy is my friend. Could Microsoft and Facebook find themselves in competition down the road? Sure. But right now they have a common enemy in the guise of Google.”

But despite Facebook’s partnership with Skype and Microsoft, Rob Enderle, an analyst with the Enderle Group, said today’s announcement does make it look like Facebook is chasing Google.

“Facebook may have started down this path first, but Google made theirs public first, so it makes it look like Facebook is catching up,” Enderle said. “Still, both Facebook and Skype have a massive lead in their respective markets and that could render Google+ redundant regardless of how good it is. Facebook and Skype have a massive advantage with respect to customer reach against the very new and unique Google + offering.”

Biochemical And Analytical Process of High Performance Liquid Chromatography

Posted on by Posted in Tech Leave a comment

What is high performance liquid chromatography and what are the other different types of chromatographic techniques? There are different types of chromatographic techniques like ion exchange chromatography, gel filtration, thin layer, and size exclusion chromatography, liquid and solid chromatography. Initially the mixture containing the sample to be separated will be dissolved in the mobile phase. Then it is passed over the stationary phase where the analyte that needs to be quantified will be separated form the other components, based on the difference in the partition coefficient of the analyte in the stationary and the mobile phase.

MCTS Certification, MCITP Certification
Cisco CCNA Training, Cisco CCNA Certification 2000+ Exams at Examkingdom.com

The high performance liquid chromatography is used to purify the analyte and also to measure the amount of a component in the sample. The high performance liquid chromatography finds a good place in biochemistry as well as in analytical chemistry. There are many companies specializing in the high performance liquid chromatography and for trouble shooting problems in the high performance liquid chromatography like SC chromatography. This is involved in repair and maintenance of high performance liquid chromatography equipments. It also aids in proper installation of the equipment and process development.

The SC chromatography offers proper solutions in order to solve the problems related to separation of a mixture to estimate the components using the high performance liquid chromatography. The tips offered by the company for high performance liquid chromatography are not warranted. There are many problems that are commonly faced when using the high performance liquid chromatography, which slow down lab work. These problems might hinder with the final outcome of the lab results or may interfere with the accuracy of the study using the high performance liquid chromatography.

To avoid such high performance liquid chromatography problems, the exact reasons and observations can be provided to the SC chromatography. In order to have a direct phone call with the high performance liquid chromatography specialists or engineers, one can contact them at the following number – 714-871-4331. Some problems of the high performance liquid chromatography tool or the process can be sorted out using the tips provided by SC chromatography. If the issues still persist and there are slow lab outputs, then it is advisable to call the high performance liquid chromatography engineers, so that they could handle the problems personally and ensure a proper solution.

The Sc chromatography is also involved in transporting of the equipments as well as providing training to lab assistants or to those who are new to high performance liquid chromatography. Some of the most common problems that one might encounter and get solved using the Sc chromatography are the leaks that might happen in the high performance liquid chromatography equipment. This greatly affects the lab output but it is one of the problems that can be very easily located and solved. There are other issues, like pressure problems and retention time problems. Sometimes contaminates get accumulated in the high performance liquid chromatography columns and produce erroneous results and lead to a major problem called retention time drift. Temperature and lack of skill may also be reasons for wrong results.

Nowadays, customers want more convenience and performance features in their fridges. It important to them that their refrigerators look attractive, have flexible food storage options and also comes with a choice of configurations such as side-by-side, top freezer, bottom freezer or counter depth.

Let’s not forget the next key factor that every buyer is now on the look-out for, an energy efficient refrigerator which will not only help save the environment but also, help keep the household budget and energy bill at a low.

Modern home appliances, like the most sophisticated model of refrigerator have been designed with some new features. The most sorts after features seem to be the through-the -door water delivery system and ideal for the summer, the through-the-door ice delivery system.

Popular Fridges
Of all the models and makes out there on the market the side-by-side refrigerator with a large freezer capacity and easy to use functions and settings seem to the most popular amongst consumers. And now, most manufacturers offer a through-the-door ice maker/water dispenser as an option on all side-by-sides makes.

Following closely behind the side-by-side, the second popular model is the Top-freezer refrigerators. These tend to offer smaller freezer compartments than side-by sides, and the freezer is at eye level, placing the refrigerator at a lower and less convenient place. But the Top freezer models are less expensive than comparable side-by-side refrigerators which is why if you are on budget these models are worth looking into if you have the required space.

Bottom-freezer refrigerators are catching on in popularity, although manufactures generally offer only one or two models of the freezer-in-the bottom units. These refrigerator freezers are the most energy-efficient. In general, most freezer doors swing open like the refrigerator doors, instead of sliding out like a big drawer as they once did. And as an added bonus, the freezer compartments on these models are larger than in top-freezer models.

More and more modern apartments tend to be fitted with this type of refrigerator- the built-in refrigerator as they can be installed all at once with the kitchen cabinets and kitchen design.. Homeowners can customise their built-in fridges to coordinate with their cabinets by adding custom panels that can be added to the facade.

Conclusion
Before you buy your new home appliance, there are a few things you need to consider. How large is the space or opening in your kitchen where you can fit the refrigerator, for example. Also, consider what features are must-haves and which features are less important for you. Think carefully about the kind of budget you can set aside for your new fridge.

Refrigerators are also adopting more energy efficient mechanisms to reduce energy costs, so consider spending a little bit more on an energy efficient model to help you cut down on your energy bills each month. The above guide provides some top tips to help you decide on the most suitable refrigerator for your needs and budget.

3D TV Tips – The Ins And Outs of 3D TV

Posted on by Posted in Tech Leave a comment

Been put off from watching anything in 3D through the fear of looking unfashionable in those red and blue cardboard glasses? Well, 3D has moved on. Find out how now.

3D TV is the newest home viewing technology to hit the TV market. This technology, while exciting, can be a little bit tricky to understand. But to make the most of 3D, it does pay to understand it a little bit more.

To achieve your very own 3D viewing experience home, there are various ways you can employ and utilise several technologies now available on the TV market.


Best CCNA Training and CCNA Certification at Certkingdom.com

It is also worth reading about what 3D TV technology has to offer before investing in the product.

Take the standard flat screen TV, what you get is a flat 2D image. But we have two eyes which allow us to view in 3D in real life. But on screen, there is no depth to the image that is being displayed- it is simply a flat array of pixels and different colours which is basically like looking at a moving photograph. But it is of course possible for a TV to create the illusion of 3D. This is known as ‘artificial 3D’ as there isn’t actually a 3D object protruding from the screen.

3D technology explained
When talking about 3D technologies, there are in fact several selections of categories in which you can divide the topic in to. There’s anaglyph 3D technology, polarised 3D technology, which is commonly found in cinemas, active 3D technology, which is the one most commonly used for home 3D systems and finally there is parallax-barrier 3D technology. They are all essentially just different ways to feed different images to each eye.

Anaglyph 3D technology
The oldest form of 3D TV technology is the Anaglyph technology. This version of the 3D TV has been around for a very long time and is the one where the image is broken into two colours, red and blue, which gives us the 3D image. If you use this technology, you do not need a special 3D TV as it works even on standard colour TVs, as long as you have the right glasses with the red and blue filters.

Polarized 3D technology – passive 3D technology
You would only find this in cinemas where they show modern 3D films like Avatar. It works well and the required glasses are cheap and light. But Passive 3D is not mainstream technology, therefore cannot be used in the home on any current 3D televisions, but it is an option that could become more prevalent in the future.

Active 3D technology
Currently the leading 3D technology for the home 3D entertainment is Active 3D. Most of the major television manufacturers have active 3D TV models either released or will soon be launching models for sale in the TV market. The technology works well, but it requires each viewer to wear ‘shutter glasses’ which are heavier and more expensive that the polarised glasses required for passive 3D TV technology.

How this technology works is within the active 3D TV technology, the screen switches rapidly between showing the image intended for separate eyes. It switches between images at least 100 times per second, sometimes even more frequently on many 3D TVs.

Parallax barrier technology
The last of the 3D technology types is called Parallax barrier which is becoming fairly popular on personal devices like handheld gaming systems such as the Sony PSP. The beauty of it is that you don’t need glasses, but have to be positioned exactly at the right spot to be able to see the 3D effect. This is because of the limitations of the technology and it’s not yet fully developed for home use.

Conclusion
Having reviewed the various 3D technologies that are available on the market for consumers, this guide offers great tips and a thorough break down of the products for better understanding. This should help you decide on your specific needs and budget when your interest in 3D TV technology starts growing.
