Extreme Networks, one of the smaller Ethernet switching vendors out there, has survived the recession so far, but its financial outlook has been dismal lately. Three weeks ago it Extreme warned Wall Street that its earnings would be down significantly for its first quarter, which ended Sept. 27. It’s expecting earnings of $66 million, down from $83.5 million a year ago.

Now Extreme has hit the restructuring button has it tries to sail through continued rough waters. CEO Mark Canepa, who’s been with Extreme since August 2006, has resigned. in order to “pursue other opportunities.” He’ll stay on board for a short time to help with the transition.

CFO Bob L. Corey has been named acting CEO as the company looks for a permanent replacement.

Extreme also laid off 70 people, about 9 percent of its workforce, in order to reduce quarterly operating expenses by $2.5 million.  This is part of an effort to make the company lean enough to break even with $70 million in quarterly revenue.

No details are available on where the layoffs came from within Extreme.

Brocade continues to exploit friction between Cisco and systems vendors

It’s debatable just how much Cisco’s move into the server market with its launch of the Unified Computing System (UCS) has truly soured the networking giant’s strategic alliances with IBM and Dell, but Brocade has wasted no time in exploiting whatever separation may arise as a result.

Cisco’s UCS strategy banks on the need for tight integration between servers, storage and networks in next-generation data centers, particularly those that use a unified fabric, such as converged Ethernet, to transport all forms of data center traffic on a single medium. Cisco see an opportunity here, believing that many enterprises will want to get all their data center equipment from a single vendor in order to build such a highly-integrated infrastructure.

Of course, as part of its plan to exploit this potential market, Cisco has introduced its own line of servers, putting it into direct competition with long time allies in the data center, such as Dell, HP and IBM.

Whatever rift that forms between Cisco and these server vendors is an opportunity for Cisco’s networking competitors.

In the year since the storage networking company Brocade bought Foundry Networks, it has been leveraging its existing partnerships with leading IT equipment vendors to expand the market for its newly acquired Ethernet switching business. Apparently vendors like IBM and Dell are only too eager to find an alternative networking partner.

Earlier this year IBM announced a major expansion to its OEM relationship with Brocade. Big Blue had been selling IBM-branded storage networking gear from Brocade for several years, but in the new deal it expanded that OEM relationship to include a broad range of former Foundry switches and routers.

And now yesterday Dell announced that it is expanding its own OEM relationship with Brocade, from a storage networking channel to a broad line of Brocade’s Ethernet products.

Dell also announced it would start reselling products from IT automation vendor Scalent Systems. This is all part of an “Efficient Enterprise” offering Dell plans to unload on the market toward the end of 2009. As a result of these new OEM deals, Dell can now offer enterprises servers, storage, networks and IT automation software in one deal, enabling enterprises to buy an integrated data center solution from one vendor. IBM is making a similar move with its OEM agreements and its consulting arm. HP is moving swiftly in this direction, too, but it has the advantage of possessing its own, rapidly growing network equipment division in ProCurve.

Soon-to-be-ex-Senator Norm Coleman’s next job: Network engineer?



Posted by: Shamus McGillicuddy
Ethernet, IT humor

We don’t spend a lot of time talking politics on The Network Hub, but I can’t resist this one.

Sen. Norm Coleman (R-Minn.), who lost his re-election bid to comedian Al Franken and who has spent the last six months litigating the election results in Minnesota’s courts, was caught on tape at some Republican shindig talking about how the GOP needs to do a better job of using new media to organize itself. He tells an interviewer in the clip below that his party needs to compete on “the Ethernet.” These poor politicians. They spend all their time glad-handing campaign donors and making appearances on cable news networks and no time actually sitting at a desk working with a computer. The entire Internet thing has completely passed them by.  Just as former Sen. Ted Stevens demonstrated his complete lack of understanding of the Internet by saying it is a series of “tubes” that you can’t drive trucks through, Norm has revealed that he probably hasn’t spent much time surfing the web either.

Or perhaps I’m rushing to judgment. As blogger Josh Marshall points out, maybe Norm, whose teeth are disturbingly white in this video, meant that the GOP needs to brush up its skills on local area networking.

While walking the floor at Interop Las Vegas last week, I met with Brad Booth, chairman of the Ethernet Alliance, who demonstrated Fibre Channel over Ethernet (FCoE). In this video, you can see how the Ethernet Alliance used priority flow control and enhanced transmission selection to protect video traffic moving over FCoE. As Brad describes, this video features a NetApp Fibre Channel array  sending Fibre Channel and ISCSI traffic across an Ethernet network into two servers. The servers are sending streaming video to a monitor while a Finisar Xgig traffic generator is blasting the network with simulated traffic.

Shocker! Cisco leads the pack in Gartner’s Magic Quadrant for enterprise LAN

When I saw that Gartner had published a new Magic Quadrant for enterprise local area network (LAN) infrastructure, I knew one thing was for certain. Cisco Systems would be THE leader in the market. The only question was for me was - how would the rest of the market shake out?

In this blog post I’ll review this year’s Magic Quadrant for the LAN market, and I’ll compare it to last year’s Magic Quadrant for Campus LAN infrastructure, which is essentially a measure of the same market.

As I wrote above, Cisco is THE leader in the LAN market, scoring high in both of Gartner’s criteria for the quadrant: completeness of vision and ability to execute.  In their assessment of Cisco’’s position, analysts Mark Fabbi and Tim Zimmerrman noted that Cisco maintains the broadest portfolio of LAN switching and WLAN technology on the market. The introduction of its Nexus switches have shown that Cisco is providing some leadership in addressing emerging connectivity demands in data centers.

However, Gartner cautioned that Cisco remains the high-priced vendor, with some workgroup switching products being twice as much as alternative products on the market. Gartner also said Cisco might be taking its customers for granted, especially those customers who believe in buying networking gear from more than one vendor. The analysts wrote:

We are hearing increasing concerns about Cisco’s presales organization taking customers for granted, and not providing expected levels of service, especially for customers that have not endorsed an end-to-end Cisco solution.

The only other leader in this Magic Quadrant is HP ProCurve, which was a leader last year as well.  Gartner described ProCurve as the fasted growing LAN switch vendor during the past two years and when clients speak with Gartner about their shortlists for vendors, ProCurve is the the second-most-asked-about vendor after Cisco. Gartner praised ProCurve’s integration into HP’s Technology Services group, which gives it access to HP’s broader sales force. It also praised ProCurve’s low cost of ownership and the successful integration of the WLAN technology it acquired with Colubris Networks.

But Gartner cautioned that ProCurve still lacks high-end core switches (An acquisition of a high end core switching vendor like Arista Networks or Blade Network Technologies would do the trick!). The company also needs to expand its channel for larger sales opportunities. ProCurve has in the past been known as a good vendor for SMBs.

A third leader from last year’s campus LAN Magic Quadrant fell down a notch in this year’s quadrant. Foundry Networks, now known as Brocade, the storage networking company that bought Foundry last year, was classified as a visionary in this year’s Quadrant, scoring high on its completeness of vision but scoring a little lower than last year in its ability to execute.

Gartner praised Brocade’s integration of Foundry but said Foundry lost momentum last year due to its U.S.-centric and data-center-centric sales focus. Gartner said it wants to see market evidence that Brocade’s integration of Foundry is successful and that Brocade can regain market momentum.  I have no doubt that last week’s announcement of a new Ethernet switching OEM agreement between IBM and Brocade will go a long way toward helping Brocade regain some of that lost momentum that Gartner is looking for.

Gartner identified three other visionaries in this year’s Quadrant: 3Com, Enterasys/Siemens and Extreme Networks.

Last year Gartner classified 3Com as a niche player, but it elevated the vendor to a visionary in this year’s Quadrant, giving it higher marks for its completeness of vision. Gartner praised 3Com’s revamped product lines and its growing market share in China and other emerging markets. H3C, 3Com’s Chinese subsidiary, has a 35% market share in China, for instance. And 3Com has a very large, low-cost R&D workforce in China. 3Com recently told me H3C has 2,300 engineers in China.  But Gartner cautioned that 3Com and H3C have been, until recently, run as two separate companies. It will be important for the two to integrate. Also, 3Com has very little market penetration outside of Asia. Gartner warned that taking products developed for China and selling them globally will be a challenge.

Enterasys, which merged with Siemens Enterprise Communications last year as part of a Gores Group acquisition, maintained last year’s position as a visionary. It drew praise from Gartner for it full complement of products from the data center to the access layer, its tightly integrated security technology, and good customer buzz around support and services. But Gartner said Enterasys’s market footprint remains small and its distribution channel is limited. Marketing has also been weak, Gartner said, as the market waits for the new combined company Enterasys/Siemens to change its name.

Extreme Networks, the third visionary in the Quadrant, drew praise for broadening its XOS-based switch line and its policy-based configuration and open architecture. But Gartner noted that Extreme is struggling to maintain revenue and it remains one of the smallest vendors in the market. Gartner also cited some support issues affecting the company’s install base.

Gartner identified two niche players in this year’s Magic Quadrant. First there is Nortel, which was downgraded from its visionary status in last year’s Quadrant. Gartner cited Nortel’s bankruptcy as an impediment to the company competing for new business. Gartner is predicting significant loss of market share and revenue for the company as it remains in bankruptcy. Gartner also said Nortel needs a new core switching platform.

The second visionary, Alcatel-Lucent, drew praise for a solid product strategy and its growing market share and revenue; however, Gartner said the company needs to invest more in R&D to keep pace with the latest innovations in data center switching and wireless LAN technology.

Force10 Networks, which was identified as a niche player last year, was dropped altogether from this year’s Magic Quadrant because it no longer meets Gartner’s revenue requirements for inclusion, whch is 1% of ports sold overall or 5% of ports sold in a specific market segment.

Gartner also noted that Juniper Networks has entered the Ethernet switch market, but it hasn’t earned enough of a revenue share to be included in this year’s Magic Quadrant. Juniper’s switches earned the company $56 million in 2008.

So there you have it, for what it’s worth. Cisco remains on top, but the other players in the market continue to make moves. ProCurve and 3Com are on the rise. Nortel and Force10 are in decline. Everyone else is looking to take a step forward.

Broadcom takeover bid for Emulex about converged Ethernet?

Broadcom is making a $764-million hostile takeover bid for Emulex, a manufacturer of storage networking infrastructure, such as host bus adaptors and I/O controllers. Broadcom, a maker of wireless and wired networking semiconductors, appears to have Emulex’s emergent Fibre Channel over Ethernet (FCoE) converged network adapters in its sites.

Cisco, Brocade and other networking vendors are evangelizing the concept of converged Ethernet for data centers, where storage and data networks are converged on a single network fabric. FCoE is a key element of this movement.  If it takes off, convergenced Ethernet could reduce the number of network connections on servers and simplify data center networking in general.

If Broadcom succeeds in grabbing Emulex, it would be well-positioned to produce the semiconductors that enable this new networking paradigm. Emulex leadership, however, seems uninterested in selling out to Broadcom. Broadcom first approached Emulex about a merger in January, but Exmulex said ‘No thanks.”

10 Gigabit and 40 Gigabit Ethernet market passes $10 billion mark.

The pipes are getting bigger and bigger. This afternoon Infonetics Research published a new report claiming that the market for 10 Gigabit and 40 Gigabit Ethernet (GbE) grew by 47% in 2008 to $10.8 billion. These numbers include optical transport technology and shipments to both enterprises and service providers. Most of those port shipments were 10 GbE, the firm said, but 40 GbE port shipments nearly tripled in 2008.

Matthias Machowinski, Infonetics’ directing analyst for Ethernet voice and data, said that 10 GbE port shipments in particular are driving overall growth in the Ethernet market. Enterprises are pushing to bring 1 GbE connections to desktops, which requires 10 GbE uplinks to the network edge. Because of this trend, 10 GbE port shipments grew by 78% last year, compared to overall Ethernet market growth of 2%.

The first pre-standard 100 GbE port shipments are expected to begin in late 2009. I’m already starting to hear from a few vendors about how they’re going to position themselves for that.

Who needs a DeLorean and its one point twenty-one jiggawatts when you can have a GigaStor SAS, which stores 288 TERABYTES of network data?

According to a press release from Network Instruments, GigaStor “is the largest retrospective network analysis (RNA) platform available for storing and capturing network packets and transactions for later analysis and investigation.” Network Instruments said that the vast capacity was needed as more networks tap into 10 Gigabit Ethernet, particularly for those companies with larger data centers. The appliance was originally designed for a military customer, according to the company, who needed to store a month’s worth of networking data.

Brocade grabs Foundry Networks, challenges Cisco in the data center



Posted by: Shamus McGillicuddy

There’s one vendor out there who is poised to challenge Cisco Systems’ dominance in the data center networking market. No, it’s not Juniper with its new line of EX switches. ProCurve Networking by HP is strong, but it doesn’t have the high-end core switches that Cisco can now boast with its Nexus family of switches.

No, the real challenger to Cisco might just be a storage networking vendor: Brocade.

Brocade announced Monday night that it has reached an agreement to buy Foundry Networks for $3 billion. The new company formed by this merger will feature Brocade’s industry leading storage networking technology and Foundry’s line of high-end service provider and enterprise class data center network switching technologies.

Brocade had already signaled its intention to challenge Cisco in the data center when it unveiled its new DCX Backbone switch last January. This chassis-based switch supports 8 Gbps Fibre Channel and emerging converged Ethernet technology. Also known as data center Ethernet, converged Ethernet holds the potential to carry all forms of data center traffic on one fabric. Instead of having separate networks for storage and for servers, companies can have one unified fabric and one set of network devices to provide connectivity in their data centers. Several standards must be ratified before this technology becomes widely available to the market, but Brocade isn’t the only vendor to invest in it early. Cisco’s new Nexus switches also support converged Ethernet. Both Cisco and Brocade have signaled that this technology is the future of data center networking.

But Brocade’s expertise and breadth of offerings in Ethernet technology doesn’t extend very far beyond it’s DCX product. That’s where Foundry comes in. Established in 1996, Foundry has a reputation for building high-density core data center switches favored by very large enterprises, service providers and Internet-class companies. Foundry lists companies such as AT&T, Google, Yahoo, Apple, Discover, Citigroup, Wachovia, AOL, Ticketmaster, MorganStanley and the U.S. Internal Revenue Service as its customers.

With the Ethernet switching expertise of Foundry, Brocade now appears ready to stake out a solid number two position in the data center networking market. A lot will depend on how well Brocade absorbs Foundry. That will take some time. Cisco isn’t exactly shaking in its boots today, but it will have to stay on its toes.
