Forget cutting to the bone. Can you cut through the bone, too?

Hey, have you heard that the economy is in bad shape? It’s bad out there. Just ask the newest Nobel Laureate for economics, Paul Krugman:

Seriously, we are in very deep trouble. Getting out of this will require a lot of creativity, and maybe some luck too.

Well you should know that analysts and vendors are lining up to give networking pros advice on how to save money in 2009.

Today I received an invitation from Enterprise Management Associates for a January webinar entitled How to Reduce Network Management Expenses in 2009. EMA vice president Dennis Drogseth will examine how automation and an integrated life cycle approach to network management can reduce costs.

Network Instruments sent us a list of the “Top five ways you can be network hero in 2009.

  • Harness the information you have. Network devices have tons of metrics that can provide cheap visibility into your infrastructure. For instance, if you aren’t doing this already, start collecting NetFlow data and aggregate it into some kind of analyzer to get real time stats on you applications.
  • Test, test, test. It’s easier to identify and budget for changes to applications before you launch them rather than after. Understand how your apps will run on the systems provided and the network provided before you allow the application team to launch them.
  • Prioritizing critical traffic. Instead of spending money to boost bandwidth, set quality of service thresholds for critical apps and allow bandwidth-hogging apps that aren’t as critical wait a little longer.
  • Stop throwing bandwidth. Slow application performance isn’t always a network issue. Bring some donuts over to the systems guys and ask them to check on how their servers are performing. Maybe they aren’t configured properly for the applications they are running.
  • Anticipate rather than react. Network managers are often in reaction mode, using analysis tools after the network has a problem. Too often they’re waiting for the problem to recur. If you run your tools continuously you can spot network issues before the user experiences them. You’ll spend less time trying to diagnose and fix them. And you’ll have more time to get everything else done.

Info-Tech Research Group has also published a list of Eight Ways to Slash Network and Telecom Costs by Half. I won’t publish them in full since Info-Tech would rather that you spend $195 to get the list from them, but here are a few brief examples of things you can do:

  • Buy used networking gear. This market has grown quite a bit over the last few years. Your vendors might not be happy with you for doing this, but they don’t need to know. I plan to write about this next month on
  • Renegotiate telecom and mobile service contracts. If you are in a position to do it, now is a good time to get a better deal from your providers. They’ll be wiling to lower their charges in order to keep your business in these dark times.
  • Get rid of T1 lines on your WAN. There are lots of cheaper alternatives out there. See if you can find something that meets your requirements at a lower price.

Trapeze not flying high over Magic Quadrant

Shamus McGillicuddy Shamus McGillicuddy Profile: Shamus McGillicuddy

Every year Gartner’s Magic Quadrant for wireless LAN infrastructure has some winners and some losers. One or two vendors will emerge from the crowded quadrant of niche players to become a market leader, a visionary or a challenger. And one or two other vendors will slip back into the crowd of niche players. This year, one of the vendors who came out on the losing end is accusing Gartner of having, at the very least, an appearance of a conflict of interest.

Brian Johnson, director of public relations for Trapeze Networks, called me last week and implied that Meru Networks is receiving favorable coverage from Gartner over Trapeze. Gartner placed Meru in the visionary quadrant for the second year in a row, while Trapeze slipped from visionary status to niche player.

Johnson revealed to me that Tim Zimmerman, one of the Gartner analysts who wrote this year’s Magic Quadrant, is a former employee of Meru Networks. I checked around and indeed Zimmerman was director of industry marketing for Meru Networks from Octbor 2007 to January 2008. Johnson also pointed out that Gartner’s former research director for wireless LAN technology, Rachna Ahlawat, is currently the vice president of strategic marketing for Meru.

Johnson explained that Trapeze has had a good year and is a superior company to Meru. He said it “stretches the imagination” that Meru could be ranked higher than his comapny.

“We have a higher market share than Meru,” Johnson said. “We have more OEM relationships. And we are a public company with a large bankroll behind us while Meru is a private company that is rapidly burning through its cash… In terms of ability to execute, I think that Trapeze has a higher ability to execute than Meru can.”

Johnson also told me that Trapeze brought eight products to market this year and three of them won awards (I looked through a list of press releases on Trapeze’s website and didn’t see that many product releases, but perhaps I missed a few). He also pointed out that Trapeze won the largest wireless LAN deployment in the world this year when it closed a deal with the University of Minnesota.

Johnson was reacting to a story about the Magic Quadrant which I wrote last week. When I talked to Mike King, Zimmerman’s coauthor, for that story, he told me that Trapeze’s downgrade was reflective of its relative silence on the market since it was acquired by Belden over the summer. He suggested that things have slowed down at Trapeze while Belden goes through the process of absorbing it. And he predicted that Trapeze could lose some key OEM partners when its deals with those expire in a few months. All this can be fairly typical for mergers and acquisitions. Motorola experienced a similar decline on the Magic Quadrant when it bought Symbol Technologies, but it has since rebounded and is now identified as a market leader by Gartner.

Now any industry veteran will tell you that analysts take jobs with vendors all the time and research firms like Gartner commonly hire analysts from the vendors they cover. Ahlawat left Gartner for Meru in June of 2007 so it’s been well over a year since she’s had any relationship with the firm. However, Zimmerman left Meru less than a year ago, so it was worth my talking to Gartner about this issue.

First I talked to Andrew Spender, Gartner’s vice president of corporate communications. He said Gartner employs a variety of measures to ensure that its analysts are independent and objective.

“First we have our principals of ethical conduct and our code of conduct which all our analysts sign up to as soon as they join the company,” he said. “They have very intensive training in what that code of conduct means and how they need to adhere to it. It’s very specific in terms of accountability.”

Spender also said that no piece of Gartner research is ever the work of one single analyst.

“When you buy a piece of research or become a Gartner client, you obtain the research from Gartner, not from an individual analyst. Each piece of research is peer reviewed. Our community of 650 analysts have a formal obligation to do peer reviews of other analysts’ research to ensure that any kinds of inconsistencies, any errors of data collection or any errors of conclusions are challenged and corrected before the research sees the light of day.”

I also spoke to Larry Perlstein, Gartner’s ombudsman (Gartner is the only analyst firm I know of that employees ombudsmen), about this matter. He has already conducted an investigation of Trapeze’s complaint.

“Basically I didn’t find anything that made me concerned that there was any real fact in Trapeze’s issues. The analyst that they expressed a special worry about, who was formerly at Meru, was there for only a very short period of time, about three months. It wasn’t clear that anything in that involvement was going to dramatically influence this particular piece of research. Most of our analysts come from vendors. As part of our hiring process we try to ensure that people have the capacity and potential to be balanced and objective.”

On the same day that I spoke to Johnson at Trapeze about this issue, I happened to chat with David Callisch, vice president of marketing at Ruckus Networks. Ruckus is another niche player in this year’s Quadrant, ranked a little lower than Trapeze.

“Tim Zimmerman and Mike King are both very stand up guys,” Callisch said. “I thought we had a pretty mediocre spot on the Quadrant, but to be quite objective, who are we to say? Vendors always think they deserve a better spot… But Tim and Mike did a lot of due diligence. I think they did a good job even if we got a lousy spot.”

He said that Gartner placed Meru high probably because the firm likes the innovative single channel approach Meru takes with its access points, which solves voice roaming very well. He said he has doubts about whether this approach can scale as well as more mainstream wireless LAN technologies, but he doesn’t fault Gartner for giving Meru high marks for their technology.

Callisch went on to call out Trapeze for its acquisition by Belden. He said Trapeze has a very good product line, but it had marketed its technology poorly, driving down the value of the company.

“They ended up being sold to Belden for pennies on the dollar and that hurt the valuation of other [wireless LAN] companies” he said.

Gartner’s WLAN Magic Quadrant: Motorla, HP and Siemens on the rise

Shamus McGillicuddy Shamus McGillicuddy Profile: Shamus McGillicuddy

Where once there were two, now there are three.

Gartner has published its 2008 Magic Quadrant for the wireless LAN infrastructure market. The most noteworthy change from 2007’s Quadrant is the rise of Motorola. Last year Gartner identified Cisco and Aruba as the two leaders in a crowded market. This year, Motorola has joined them as a third market leader.

HP ProcCurve (which purchased Colubris this year) and the newly merged Enterasys/Siemens Enterprise Communications both advanced from niche player status to visionaries. Trapeze Networks appears to have taken a step backwards since it was acquired by Belden, slipping from visionary to niche player.

Meru Networks remains in the visionary quadrant, although it is on the cusp of climbing into market leader status.

Cisco tightens their belt while Aruba sharpens the ax

Michael Morisy Michael Morisy Profile: Michael Morisy


The notoriously frugal Cisco is tightening their belts a little tighter, more or less shutting their offices over the holidays and freezing hiring for a bit. They hope to save $2 billion, which isn’t small change even for the world’s largest networking equipment provider.

They also are looking to cut travel expenses, and since Cisco insiders tell us everyone at the company flies coach to begin with, we guess that means more TelePresence. Layoffs, however, are not planned, at least for now, according to Dow Jones Newswires:

Cisco Systems Inc. (CSCO) doesn’t have any layoffs planned at this point, according to Chairman and Chief Executive John Chambers. …

Chambers, speaking to analysts at a conference hosted by Credit Suisse, said that if the company was to have layoffs, it would be a one-time event, rather than a string of events.

Sounds like he’s hedging his bets, just in case, but it might be tough to cut the fat from Cisco’s already lean (for a company of their size) operation.

Aruba isn’t so optimistic. The company announced they will be cutting jobs to reduce operating costs by 10%, though the exact number getting laid off is unknown.

This is despite Aruba’s record revenues last quarter, which, according to Farpoint Group’s Craig Matthias, came at a price:

“If you look at Aruba’s margins, they have eroded some, and obviously discounting is a heavy element in winning deals,” Mathias said. “So I’m expecting that their margins probably won’t improve much with their sales. But this is an industry that will continue to grow, and it will accelerate into the future.”

It also calls into question what wireless vendors keep whispering to me: Their equipment — and business prospects — are counter-cyclical. The theory goes that wireless is a great way to cut costs: No more having to futz around to rewire desk connections, less physical wiring to lay down, etc. etc. But with such a crowded field of vendors, even the winners might have a tough time staying or getting profitable.

What’s 007 in binary?

Michael Morisy Michael Morisy Profile: Michael Morisy

If you ever find your networking career a little too pedestrian, always know that your IT skills can land you a much more exciting gig if you’re willing to take the risk:

Ali Ashtari, 43, a computer and hi-tech equipment buyer for Iran’s defence industry and nuclear programme, was hanged after admitting he worked for Israel. It is the first known conviction of an alleged Israeli agent in Iran for almost 10 years. …

Behind their backs he allowed the software he bought to be subtly doctored by Israeli computer engineers before it was imported to Iran. Ashtari confessed: “Mossad’s goal was to sell specialised computer equipment through me to Iranian intelligence organisations.”

The case echoes the FBI’s warning not too long ago about Cisco knockoffs as potential Trojan horses, but this time, the threat was apparently real — or at least real enough for Iran to take action.

Corporate espionage is a very real threat, as Intel found out recently, but people aren’t generally executed for it.

As for me? I’ll stick with the IT spying antics of Chuck — a little less realistic, perhaps, but fewer people end up getting killed. In this clip, Chuck and company use social engineering techniquesone of network security’s weakest points — to infiltrate the opposition.

Is Cisco’s coming voice CCIE refresh going to leave CallManager pros out in the cold?

Michael Morisy Michael Morisy Profile: Michael Morisy

Happy Feat

As Cisco unveils the latest addition to the wireless certification line up, its voice CCIE certification is getting a refresh, which had at least one analyst worried some voice experts will be left in the cold.

Cushing Anderson, program vice president of IDC, is concerned because the new voice CCIE, which will go live in July 2009, will be based on Cisco Unified Communications Manager 7.0 software. At that time, a Cisco representative said, the old test labs using Cisco CallManager will no longer be available.

Anderson said Cisco CallManager 4.0 will likely remain in some enterprises for years to come. Unified Communications Managerr was released in September, and many enterprises have no immediate plans to upgrade just yet.

“If people are still using older stuff, shouldn’t people still be able to test on the older stuff?” he asked. “That’s frustrating to me.”

Christine Yoshida, senior manager of learning and development for Cisco, said the sharp cut off date means Cisco can cover on a wider range of UC concepts.

“It’s a more robust, comprehensive skill set that we’re able to test,” she said. In addition, she said, those interested in specifically supporting CallManager will still have CCNA and CCNP certifications.

Over at the InternetworkExpert blog, reaction has been positive, ranging from “At last !!! Yahoo !!!” to “Great! Ive been waiting for these for a while.” Brian Dennis also breaks down the software and equipment that will be used in the updated lab.

What are your thoughts? Is Cisco dropping CallManager too quickly, or does their push on ahead with Cisco Unified Communications Manager give you happy feet? I’d love to hear your opinion.

HP ProCurve could threaten Cisco’s dominance

Shamus McGillicuddy Shamus McGillicuddy Profile: Shamus McGillicuddy

The New York Times has an interesting article about the rise of ProCurve, Hewlett Packard’s networking division. Gartner analyst Mark Fabbi told the Times that Procurve’s revenue has grown by 40% over the last two quarters, putting some pressure on Cisco’s status as the undisputed market leader.

The story explains that HP’s change in leadership from Carly Fiorina to CEO Mark Hurd has had a major impact on the company’s networking business. Fiorina maintained a close partnership with Cisco, in which HP sold computers and printers and Cisco sold networking gear to the same customers. Fiorina even offered incentives to HP sales reps who sold Cisco equipment without offering similar rewards for selling ProCurve gear. Hurd has reversed this policy, encouraging HP to focus on sales of ProCurve technology.

The company has also built up its ProCurve division this year through acquisition. This summer HP acquired Colubris, a maker of wireless LAN technology known for high quality products that are favored by manufacturers, hotels and other vertical industries that require reliable, large-scale wireless networks. Colubris also gave ProCurve instant credibility with 802.11n, the next generation of wireless LAN technology.

While HP builds up its networking business and threatens to be a serious competitor in the industry, Cisco has its eyes on a much bigger threat: the recession. Cisco has announced plans to shed $1 billion in expenses in order to keep its margins healthy during the downturn. Citing UBS Research, GigaOm has reported that Cisco will shut down operations for four days at the end of this year to save money. This follows other reports that Cisco has canceled its annual sales conference in San Francisco.

Five things network administrators do to mess up their enterprises’ virtualization

Tessa Parmenter Tessa Parmenter Profile: Tessa Parmenter

Selecting the Right Virtualization Solution

Network monitoring authority Paessler PRTG has seen the good, bad and ugly of network designs that prevent monitoring a system, which is why their product line solutions cover everything from network management to server performance.

To get an idea of what they’ve seen, PR rep Michael Krems got the company talking about the top five most common mistakes network administrators and IT systems managers make that cause their virtualization deployment to fail.

Here’s what Paessler says will mess up your enterprise’s virtualization:

  1. Virtualizing systems without knowing their usual CPU/memory load, disk usage and network usage: You must monitor a system prior to virtualization in order to know how much load it will put on your VM host servers. System with high load may also be not suitable for virtualization at all.
  2. Running too many VMs on a host: causing overloads: All virtualized systems suffer in performance.
  3. Running too few VMs on a host: spending too much money buying too many host server[s]
  4. Compare mid/long-term monitoring results before and after virtualization to ensure quality of service doesn’t suffer.
  5. The performance of all virtual systems on a host usually suffers from one virtual system going amok or running into a performance/load peak. Without monitoring, such events often happen undiscovered.

It seems like applying common sense would fix a lot of the issues surrounding virtualization. I wouldn’t place a lot of blame on the network manager though. Much of what goes wrong with a virtual deployment just has to do with the capabilities of the technology. Take these issues for instance:

As with any new technology, most of the struggle too, is not having the right information. In the end, do you feel like enough conversation surrounds the impact virtualization has on your network?

Microsoft offers free certification exam retake

Tessa Parmenter Tessa Parmenter Profile: Tessa Parmenter

Can’t afford to get certified? Well, these days, with an even more competitive job market, you can’t afford not to be.

The good news is that Microsoft is giving you two incentives to certify for their exams. Through Second Shot, you get to retake your Microsoft certification exam for free if you don’t pass on your first try.

If you’ve mastered the test on your first try, then you get 25% off your next exam that you decide to take.

All you have to do is register for Microsoft’s Second Shot offer by December 31, 2008. Details can be found on their website (in cased you missed the link above):

If you need that little extra nudge, think of it this way: Those who have higher credentials, especially of the expert levels, get higher pay. If you want to be Microsoft Certified Systems Engineer (MCSE) certified, for example, you need to pass about seven exams altogether. Each one costs $125 through Prometric, so if this seems steep now, think of the payoff later down the line with your new starting salary!

If MCSE isn’t the exam for you, take a look at this newtorking certification guide from our career and training expert, Ed Tittel, to get a taste of the certification landscape. If you need some certification or career training advice, feel free to check out Ed Tittel’s expert section or ask Ed your own career question to guide you in your work ahead.

IT economic outlook: Not so good

Tessa Parmenter Tessa Parmenter Profile: Tessa Parmenter

One way to make financial projections into your company’s IT future is by taking a look around at other IT corporate giants, like Google and Cisco, to see how they are faring. If the company at the top of the food chain is feeling affects from a depressed economy, then chances are, lower down the chain, you’re going to be feeling twice the burden.

magic 8-ball outlook not so good

This past August, although Cisco reported strong 2008 earnings (Compared to last year, net sales were up 9.9%, net income was up 4.4% and earnings per share were up 6.5%.), today, Outlook’s Ritsuko Ando reported Cisco’s shares were down 28% from a year earlier. This downward jump is a jolt I’m sure we’ll all be feeling.

On election day, Scott Moritz of Fortune 500 magazine wrote:

“As a supplier of Internet gear and computer networking systems, Cisco has a broad reach into markets across the globe. And given its position as the dominant provider of data infrastructure, Cisco’s view of tech spending trends, while not always accurate, commands a great deal of attention.”

After all, seeing Cisco Looks into the Abyss at the top of commanded my attention.
