The Nexus is no Lexus

February 13, 2008 6:56 AM | 3 Comments

Lexus has a reputation as a high quality, high performance, high reliability automobile. How does the recently announced Cisco Nexus 7000 stack up to its near-namesake?

High quality right? The Nexus is a new technology for the core data center, with new hardware and a new unproven OS (they call it release 4.0, but this isn’t very convincing).

One of our customers told us: “We have a strong focus on being environmentally friendly and helping to improve the world we live in. It is in our strategic objectives that, the environment and sustainability will be a key element of our business proposition."

Gartner estimates that companies in the U.S. spend as much as 10% of their total IT budgets on power and cooling. Most of the discussion on Green IT has been with respect to the data center, which Gartner estimates represents over 23% of global carbon dioxide emissions from ICT.

Today's Juniper announcement marks their entry into the Ethernet switching space, one which is dominated by Cisco. In my view, it makes enterprises think twice about procurement strategies which rely on a single vendor (Cisco) solution, with lost agility and poorer price/performance.

That said, Juniper will be challenged on a number of fronts:
#1 Enterprise is not carrier. Juniper has been successful in taking away Cisco share in the carrier router market, but their recent entry into the enterprise router market has resulted in a 1% share (according to Dell'Oro).

Consolidation, centralization and virtualization of storage and processing are the generally accepted paths to increased agility, to lower TCO and to the greening of IT.

With Microsoft making its virtualization play, the focus will shift during the remainder of the decade from servers and storage virtualization in the data center to virtualization in the network, to meet business, organizational and governance requirements; for example, federations across partners and suppliers; common infrastructures across separate entities; and security, sensor and telemetry domains in a hyperconnected enterprise.

I'm not talking about just partitioning a router or firewall device. I'm talking about a new level of virtualization that allows dynamically controllable isolation of routing, security and performance of multiple logical network topologies on a single IP network.

Securing The Hyperconnected Enterprise

December 10, 2007 12:12 PM

One of the greatest impacts of Hyperconnectivity is in the security area.

Multiple approaches to security enforcement should be used in different parts of the network, operating under enterprise-wide policies. This ‘layered defense’ is further bolstered by adopting an open-security philosophy that embraces a security ecosystem leveraging security leaders such as Symantec, Check Point and Sourcefire.

I recently spoke to an Israeli financial institution that was experiencing 25,000 attacks per day (not a typo!).

In my Oct 22 posting "Beware the Single Vendor as Trusted Advisor: Gartner", I discussed with you the pitfalls of single vendor networking. Well opportunity knocks and I had a chance to debate Cisco on this hot topic.

Take a look and tell me what you think about dropping Cisco in favor of best in breed vendors.

Let's talk about Hyperconnectivity and network implications of unified communications and of an explosion in network-connected devices - for example, in the realms of energy and property management, asset and location tracking, telemetry and enhanced security systems. This is enabled by low-cost sensors and actuators that can detect over 100 different physical parameters, including temperature, radiation levels, door closures, visual and audio signals and location - and that can cost-effectively transmit this information.

Scaling the network by a factor of 10 to 100, the most obvious of a number of new requirements, can’t be achieved without fundamentally streamlining current network environments. Hyperconnectivity demands simplification on a grand scale, transforming the network into a business optimized infrastructure.
