Cisco might be trying to win the hearts and minds of consumers, but it hasn't forgotten that its large business customers still pay the bills.
On Monday, the company plans to announce its most significant switching product for large companies since it introduced its Catalyst line of Ethernet switches in 1994. The new Nexus 7000 is a modular chassis that combines IP routing, Ethernet switching, security and storage into a single hardware and software platform. The product, which is expected to have a life cycle of decades rather than years, will serve as the centerpiece of Cisco's strategy to help large companies build new and more efficient data centres using its technology.
For more than 20 years Cisco has provided networking infrastructure to businesses large and small. The company has enjoyed over 80 percent market share in IP routing and Ethernet switching for several years, beating out competition at almost every turn. But as the company aims to grow its revenue to $50bn (£25bn) a year or more, it needs to find new markets to energise growth — and so it has. The company has been bulking up its service-provider business and taking bold steps into new markets like the consumer electronics industry.
But the enterprise market still makes up more than 50 percent of Cisco's sales, and some industry experts warn that Cisco's traditional routing and switching revenue stream may be running out of steam. Not only is it difficult for the company to grow the business in which it already dominates, but the networking gear that it sells could become commoditised, with falling prices eating into Cisco's enviable profit margins.
The data centre, which is on the cusp of major change, is Cisco's opportunity to tap into a market that could be just as big as its Ethernet switching business. But, to pull this off, the company will have to convince IT managers to take a new network-centred approach to building their data centres, a move that will likely pit the company against some of its biggest partners.
The amount of data going over networks today is in orders of magnitude greater than it was a few years ago. All of that information has to be stored somewhere

"The enterprise is Cisco's cash cow," said Zeus Kerravala, senior vice president at Yankee Group Research. "It's what allows them to do other things like go after the consumer market. But Cisco also needs to find new markets within the enterprise to drive future growth, and that's what the data centre is about."
The data centre in transition
As consumers and businesses move to more web-based applications, the amount of data being accessed and stored in the network has ballooned. On the consumer side, there are the social-networking sites like MySpace.com and Facebook that are accessed constantly and where photos and video are stored and shared. On the corporate side, companies are moving towards more web-based applications to access client information or collaborate with partners and between different groups.
"The amount of data going over networks today is in orders of magnitude greater than it was a few years ago," said Arun Taneja, founder and consulting analyst for the Taneja Group. "All of that information has to be stored somewhere — and it has to be accessible to people."
More servers and storage devices are added to the data centre all the time to keep up with demand. But adding devices adds capital and operational costs. And often the servers and storage devices are only 25 percent to 35 percent utilised. To keep up with demand while managing operational and capital costs, a trend toward virtualisation has emerged. For the most part, this has meant consolidating multiple servers or storage devices onto a single machine.
Cisco is taking advantage of this trend as it consolidates the functions of multiple devices into one. The new Nexus 7000 switch combines switching, IP routing, storage and security into a single device. And, while it doesn't necessarily take over the functions of servers or storage area devices in the data centre, it will allow companies to use their servers and storage devices more efficiently.
"Right now the data centre is going through a massive transformation," said Jayshree Ullal, senior vice president of the data centre switching and services group at Cisco. "And we see a big opportunity. In fact, we think the data centre and unified communications will be the two fastest-growing sectors in the enterprise over the next three to five years."
But Cisco's view of the new data centre is very different from those of other companies. IBM and HP are more server-centric. And EMC is more focused on…

High quality? The Nexus is a new technology for the core data center, with new hardware and a new unproven OS. And it doesn’t even support Fibre Channel?
High performance? Look again. One slot has a max I/O of 230 Gb/s and with 10 slots per shelf, my math says 2.3 Tb/s is the real capacity. And it’s an energy hog in spite of Cisco’s claims to the contrary.
High reliability for data center applications? Wrong again. It takes the Nexus 7000 4-5 seconds to recover from network failures (it doesn’t even support the much touted VSS capability). And no intelligent services virtualization and limited module options complicates real data center networks.
