The future of enterprise networking is no more networks



Posted by: Tessa Parmenter

At Burton Group’s Catalyst Conference, I chatted briefly with speaker Matt Lavallee about how the conference was going, and he asked me this question: “Have there been any surprises for you?”

In short, my answer was “yes.” But in long, if the title of this blog post is any indication, I was quite taken aback by what I heard from Burton Group senior analyst David Passmore in his first session on the “wireless everything” era.

When I spoke to Passmore last week in an interview on computer networking trends for 2009, I hadn’t quite realized that his future of networks meant the extinction of them.

In the first point of our interview Passmore stated, “Wireless is one [networking trend of ‘09] because there’s an increased use of mobile phones for both data as well as for voice. We’re also seeing enterprises using wireless LANs (WLANs) often as a substitute for wired Ethernet.” From these trends, he suggested that we would some day no longer need networks.

Consider this tongue-in-cheek dialogue between Passmore’s explanation of this at Catalyst and the audience’s reaction:

Passmore: For longer-term networking trends, we may actually see the disappearance of enterprise networks.

Audience: Blank, saucer-eyed staring

Passmore: You’re probably thinking, “How can that be?”

Audience: Those not nodding vehemently to his question are doing so internally, thinking “Yes, how can that be?”

Passmore: Well, we’re already seeing a shift from wired Ethernet access for the use of wireless LANs.

Audience: OK, but that’s still a network — hence the “n” in wireless “LAN”…

All kidding aside — what he meant was that Ethernet is very surely being replaced with wireless, which will then be replaced by 4G mobile cellular data. Does this seem probable? I think he has a valid point, but how soon will a transition like this occur? Will the network engineer have to move into wireless telecommunications in his lifetime? Who’s to say?

Persistent, reliable and secure wireless LANs (WLANs) remain the top concern for networking professionals across all verticals. However, John Gaede, Director of Information Systems at El Centro Regional Medical Center (ECRMC), has presented a compelling case to use it in the health care industry – safely and reliably. In this Q&A video below, I speak to Gaede at Burton Group’s Catalyst conference in San Diego to address these concerns and gain insight into how next generation WLANs could contribute to healthcare reform in the United States.

Dell’Oro will adjust reporting after WLAN market share squabble

802.11n, Meru, Aruba, Dell'Oro, wireless LAN, Wireless networking

Earlier this month I wrote a story about how Aruba and Meru were both claiming second place in the 802.11n enterprise wireless LAN market based on the same numbers from Dell’Oro Group. There were a variety of claims made by the vendors over the issue, but the central discrepancy appeared to be how OEM sales were counted towards market share. Aruba has a significant OEM channel through Alcatel-Lucent. Dell’Oro reports market share based on brand, so Aruba wasn’t getting credit for the sales Alcatel made.

Today Dell’Oro sent a letter to Aruba, which I peeked at today. In it, Tam Dell’Oro wrote that her firm will “add a section to our Enterprise WLAN Vendor Tables with our 2Q09 report which reflects the data by manufacturer. That is, those shipments that are produced by Aruba, regardless of which distribution channel it flows through, will be reflected as Aruba.”

Based on that, Aruba’s market share in 802.11n access points appears to be significantly higher than Meru. Aruba moved 15,000 802.11n APs in the first quarter of this year (both Aruba and Alcatel-Lucent branded products)  versus Meru’s 10,000.

It’s not clear to me at this time wheter Dell’Oro will start reporting OEM sales data in this way for other markets beyond wireless LAN.

Computer networking trends 2009 from senior Burton Group analyst at Catalyst conference

The needs of the network are changing in 2009 as enterprises centralize their data centers, rely on fluid storage sources and depend more and more on wireless LANs instead of wired Ethernet. At this year’s Catalyst show in San Diego, I spoke with senior Burton Group analyst David Passmore, to grasp what trends will directly impact enterprise technology and what IT professionals need to prepare for in both the short and long term. Here is what Passmore had to say:

1. As the networking track chair of Burton Group’s Catalyst conference 2009, what major themes will you be addressing this year?

David Passmore: From a networking standpoint, there were four areas we thought would be of most interest for our enterprise IT clients:

  • Wireless is one because there’s an increased use of mobile phones for both data as well as for voice. We’re also seeing enterprises using wireless LANs (WLANs) often as a substitute for wired Ethernet.
  • The second focus is on wide area networking and what’s happening in the telecom industry, with particular emphasis on what enterprises can do to save money. If you’re a large enterprise, your phone bill, for example, is the second largest recurring expense after salaries. Obviously, if there’s any way for large enterprises to save on their telecom costs, then that’s going to be of interest.
  • A third area that we wanted to focus on is unified communications, which essentially is an outgrowth of phone systems — where most large enterprises over the last couple of years have been migrating over to VoIP and IP telephony. Now what they’re doing is trying to figure out how to combine these systems with instant messaging and presence and email, and other forms of communication.
  • The fourth area is data center networking: most enterprises have in recent years, consolidated their datacenters: So they’ve gone from a large number of smaller data centers to a small number of larger datacenters. In doing so, now they’re beginning to implement server virtualization. They have these large storage arrays. And essentially, they need a new network that can support the IT requirements in a consolidated datacenter. So we’ll be talking about — for example, how to have your network work well with virtualized servers, and with storage area networks based on Ethernet, and trying to reduce cabling costs — a lot of the issues that affect networks in large enterprise datacenters.

2. How have these themes changed since Catalyst two or three years ago?

Passmore: Each of them has their own specific changes. A big emphasis this year given the economic environment is saving money or cost avoidance. So a lot of the discussion is around initiatives that provide a near-term economic payback.

3. Are the trends this year something we can apply to today, or something to think about for the future?

Passmore: Actually, it’s a combination of both. One of the things we always try to do at Burton is to avoid just telling people what’s worked well in the past. We tell large enterprises what they need to pay attention to or what needs to be on their radar screens as they go forward — such as wireless. The fact that, increasingly, communication is migrating from wired infrastructures to wireless infrastructures, and that includes, not just the use of WLANs within the enterprise, but more use of cellular, data and voice networking.

At some point this might actually make the [networking professional's] jobs easier, because they might find that more and more of their enterprise’s communications is actually flowing over a wireless network operator['s] network. There will be less of a need for enterprises to have to run their own circuits to manage their own networks for connectivity between or within their sites.

Right now, it’s more of a burden because enterprises have to worry about both wired and wireless communications, and people will look at that as doubling their expenses.

In the near term it, it may be doubling the expense, especially because enterprises are interested in how they can get those to work together. For example, [users] have a single phone number that works for both your desk phone and your cell phone; [they] have a single voice-mail box that works for both their desk phone and their cellular phone.

So that’s the near-term goal, but longer term, we expect that a lot of the enterprise equipment will go away in favor of people making use of mobile devices and using the cellular network operator services.

To learn more about these trends, Passmore speaks particularly about how to overcome the challenges storage and server virtualization puts on networking pros, in this Q&A.

This week in WLAN adoption: Schools love Ruckus, Aruba gets logistical



Posted by: Shamus McGillicuddy
Ruckus Wireless, Aruba, wireless LAN, 802.11n

Looking at last week’s wireless LAN adoption news…

Ruckus took the opportunity this week to announce that 24 colleges and universities have decided to install Ruckus’ 802.11n wireless LAN technology over the last 90 days. The most recent school to sign on is Benedict College in Columbia, S.C.  Benedict will run campus Internet radio and television over the networks, as well as IP video surveillance.

The rest of the schools that have signed on with Ruckus include Temple University, the University of Pennsylvania, the University of Virginia at Wise, Carleton University, Emmanuel College, the University of Toronto, Lake Superior State University and an assortment of international schools in Switzerland, Canada, Costa Rica, Indonesia, India, and Malaysia.

Meanwhile, Aruba Networks announced that French logistics company Groupe FM Logistic has bought Aruba’s AirWave Wireless Management Suite to manage its heterogeneous wireless LAN network in warehouses spread across 12 countries.

Group FM Logistic will use AirWave’s role-based administration and its fault and management reporting features to consolidate management of its Cisco and Motorola Wi-Fi hardware.

UPDATE: Ruckus’ original press release on its higher education customers mistakenly identified Temple University as a customer. Temple University is actually a Meru Networks customer.

In a new semi-regular feature on The Network Hub, I’m going to provide a quick run-down of newly announced wireless LAN projects. I get a lot of press releases from WLAN vendors about customer wins. I don’t get to write about all of them, but I can at least offer you a quick summary of the latest decisions your peers have made.

First up is John Marshall Law School, which is deploying an 802.11n wireless LAN network from Aerohive Networks on its Chicago campus. The school is replacing a legacy WLAN from Airspace (acquired by Cisco in 2005).  The old system was presenting interference and attenuation problems within the school’s century-old buildings. Centralized management was also an issue. The school chose Aerohive from a short list that also included Aruba, Meru and Xirrus.  The school chose Aerohive for its ease of deployment, controllerless architecture and wireless mesh capabilities, according to the case study.

Also this week, Aruba Networks announced that Virginia Union University has chosen their 802.1n wireless LAN to retrofit the wireless network on its 84-acre campus in Richmond (Click on this link for more information on Aruba’s specific solutions for the education market). The school had a network of independent, “Fat AP” access points that lacked centralized management capabilities and performance. Robert Gray, the schools IT director, said he chose Aruba’s AP-125 access points for their coverage and range. He is also using some of Aruba’s advanced management technologies, such as Adaptive Radio Management, Aruba’s policy-enforcement firewall and the AirWave Wireless Management Suite.

Meru and Aruba both lay claim to second position in 802.11n WLAN market

Would the real second fiddle please stand up and take a bow?

This week both Meru Networks and Aruba Networks have issued press releases claiming that they hold the second biggest share of the 802.11n wireless LAN market. Not only that - both vendors are citing the same research: Dell’Oro Group’s “First Quarter 2009 Wireless LAN Report.”

Yesterday, Meru announced that it had earned 12% of total vendor revenues for 802.11n products, ahead of Aruba (the long-standing second-place WLAN vendor).

Today Aruba sent out its own press release refuting Meru’s claim. Aruba claims a 15.5% market share. In his email, Aruba Head of Strategic Marketing Michael R. Tennefoss wrote: “Yesterday Meru issued a press release claiming that it had displaced Aruba from the #2 position, a statement not born out by the facts as Meru neglected to include Aruba’s substantial OEM sales.”

I’ve left a message with Dell’Oro’s president, Tam Dell’Oro for some clarification on this. I’ll update later with her response.

Wireless LAN spending is down, 802.11n spending is up



Posted by: Shamus McGillicuddy

Market analyst firm Dell’Oro published a 1st quarter assessment of the wireless LAN market which showed that a severe 11% drop in enterprise spending from the 1st quarter of last year and a 15% drop from the 4th quarter of 2008.

Dell’Oro says Cisco’s huge share shrank a little, from 63.1% to 60% from a year earlier. HP ProCurve doubled its share from 1.7% to 3.1%, no doubt thanks to its acquisition of WLAN vendor Colubris. Aruba’s share is 8.1% and Motorola’s is 5.9%.

Despite the overall poor showing for WLAN, 802.11n technology sales grew 4% from the 4th quarter of last year, according to a report from PCWorld.  and 802.11n technology now makes up the majority of the WLAN sales for the first time ever.

Cisco’s domination in the wireless LAN market remains intact, but it’s interesting to see their share shrink just a little bit. In fact, looking at the numbers, the amount of market share Cisco lost equals ProCurve’s ENTIRE market share.

The WLAN market remains extremely crowded and some of the largest network infrastructure vendors not named Cisco (Brocade, Juniper) lack a true WLAN product line. I expect to see some more consolidation before the recession ends.

Aruba Networks joins lifetime warranty club



Posted by: Shamus McGillicuddy
Aruba, HP ProCurve, wireless LAN

Aruba Networks announced this morning that it will now offer lifetime warranties on all its indoor wireless LAN access points. This will provide some nice investment protection to customers. It’s pretty clear to me that the lifetime warranty approach that HP ProCurve has adopted is going to rub off on other other networking vendors who are vying for share of the market that Cisco hasn’t locked up. It’s also possible that Aruba is recognizing that ProCurve is now a serious competitor for WLAN business in the wake of its acquisition of Colubris last year. ProCurve extended its lifetime warranty approach to Colubris’ entire product line after it closed the deal for the company.
