Cisco Unveils Nexus & Catalyst Products for Data Centers

Cisco unveiled a number of additions to its Nexus family of switches along with several enhancements to its Catalyst product line. These include:

  • The new Cisco Nexus 7018 joins the Nexus 7000 Series with an 18-Slot Chassis that provides up to 16 I/O module slots supporting up to 512 10Gigabit Ethernet ports to meet the demands of the largest data center deployments. The Cisco Nexus 7000 Series supports end-to-end data center connectivity, consolidating IP, storage, and interprocess communication (IPC) networks onto a single Ethernet fabric.

  • A new 48-port Gigabit Ethernet fiber line card also joins the Nexus family to support mixed Gigabit and 10 Gigabit Ethernet environments. Virtual Port Channels (VPC) also enable higher availability, large-scale virtual machine mobility, and higher bandwidth.

  • Improved data center energy efficiency - the Cisco Nexus 7000 Series uses power supplies with up to 90 percent efficiency. Fan modules in the chassis adjust to compensate for changing thermal characteristics, meaning less power is wasted as heat and more power is available for the system to use.

  • The new Cisco Nexus 5010 28-port switch is a one rack unit (RU) switch supporting 10 Gigabit Ethernet, Cisco Data Center Ethernet (DCE), Fibre Channel over Ethernet (FCoE), and Fibre Channel, able to consolidate traffic from local area networks, storage area networks and server cluster onto a single unified fabric.

  • The new Cisco Nexus 2000 Series Fabric Extender helps IT managers cope with two key data center factors: increasing numbers of servers and increased demand for bandwidth from each server. The Cisco Nexus 2148T Fabric Extenders connected to dual Cisco Nexus 5020 Switches can support up to 2,496 Gigabit Ethernet servers, greatly improving scalability of the access layer without increasing management points within the network. The Cisco Nexus 2000 switches can be combined with the Cisco Nexus 5000 Series Switches provides as an access-layer strategy for Gigabit Ethernet and mixed Gigabit and 10 Gigabit Ethernet server environments.

  • Cisco Catalyst 6500 enhancements enable customers to use the Catalyst 6500 as a virtualized service node together with a Nexus core to secure and accelerate applications cost effectively. Other software enhancements include an In-Service-Software-Upgrade and support for long range integrated 10GbE optics reduce the time needed for planned network maintenance and facilitate virtual machine mobility across data centers.

ADC Supplies Broadcast Gear for Super Bowl

ADC's connectivity broadcast gear has been deployed in Corplex Inc.'s mobile HD production units, which will support the upcoming Super Bowl in Tampa Florida this week. Specifically, ADC's ProPatch Miniature (PPM) System is deployed in Corplex's Iridium and Zinc HD mobile production vehicles.

ADC also announced that its InterReach Fusion in-building cellular solution has been deployed at Tampa's 65,000-seat Raymond James Stadium to support mobile services for capacity crowds at football games and other events. The system will provide coverage throughout the stadium, including the inner bowl, all seating levels, luxury boxes, offices and locker rooms, and the stadium parking area.

"As the broadcast market changes and the demand for higher bandwidth gear increases, the space on our mobile production units is still limited to 53 feet and 80,000 pounds, so we are constantly looking for new advancements and products that can help us utilize this same space in better ways," said Dave Greany, vice president and partner at Corplex. "ADC's ProPatch Series frees up valuable space in the mobile unit by providing 30 percent more density. This translates into a third less space and half the weight of a normal patch bay so I can get more equipment in the truck. And ADC's PPM patching systems work the first time, every time."

Cisco Debuts EnergyWise for Catalyst Switches

Cisco unveiled its EnergyWise technology for enabling Cisco Catalyst switches to play a key role in measuring, reporting and reducing electricity consumption across an entire organization, including IP-enabled devices such as phones, laptops and access points along with entire building systems such as lights, elevators, and air conditioning and heating.

Cisco EnergyWise will roll out in three phases to improve IT and building system energy utilization:

  • In the first phase (February 2009), Network Control, Cisco EnergyWise will be supported on Catalyst switches and manage the energy consumption of IP devices such as phones, video surveillance cameras and wireless access points. Initially, this includes devices connected by Power-over-Ethernet

  • In the next phase (Summer 2009), IT Control, there will be expanded industry support of EnergyWise on devices such as personal computers (PCs), laptops and printers.

  • In the final phase (Early 2010), Building Control, Cisco EnergyWise will be extended to the management of building system assets such as heating, ventilation and air conditioning (HVAC), elevators, lights, employee badge access systems, fire alarm systems and security systems.

To enable interoperability and integration between building infrastructure, IT applications and Cisco EnergyWise, Cisco has acquired a middleware platform from Richards-Zeta, a privately-held company based in Santa Barbara, California.

Cisco also introduced adaptive power management functionality in the Cisco Wireless Control System to save power by enabling customers to turn off redundant radios during off hours.

Cisco is working with Schneider Electric for building utility management, SolarWinds for network monitoring, and Verdiem for monitoring PC power in order to extend EnergyWise as a platform for power management across IT and the building systems of an organization by early 2010.

"Cisco believes that information technology has the power to transform the way the world manages its environmental and energy challenges. With EnergyWise, Cisco is uniquely positioned to help our customers gain a network wide view of energy consumption that encompasses not only device-level power, but in the future entire network efficiency, building operations and business practices across an entire organization," said Judy Lin, senior vice president of the Ethernet Switching technology group for Cisco.

Bookham and Avanex to Merge

Bookham and Avanex, both leading suppliers of optical networking components, agreed to merge in an all- stock transaction. Avanex shareholders will receive 5.426 shares of Bookham common stock for every share of Avanex common stock and will own approximately 46.75% of the combined company.

The combined company, which will offer an extensive portfolio of terminal and line products for the metro and long haul markets, will be led by Alain Couder who will serve as President and CEO. The company is expected to have two telecom divisions and one non-telecom division. The board of directors will be composed of Alain Couder and three additional directors from the Bookham board, and Giovanni Barbarossa and two additional directors from the Avanex board.

A new name for the combined company will be announced at closing. Together, the new company will have annualized revenue of about $447 million ($181 million for Avanex and $226 million for Bookham).

"The combination of Bookham and Avanex creates synergies that we expect will significantly improve financial performance faster than either of the two companies could accomplish on a stand-alone basis," said Alain Couder, president and CEO of Bookham. "There is minimal product overlap between our businesses allowing us to quickly expand sales opportunities and improve service to our customers. In addition, both companies have strong technology platforms and the best engineering teams that we expect will allow us to drive innovation and expansion for both existing and new growth areas."

Sun Microsystems opened its latest energy-efficient datacenter in Broomfield, Colorado. datacenter. The facility incorporates the latest in Sun's portfolio of energy-efficient systems and expertise, including new datacenter design and power and cooling technologies. Sun estimates it will save more than $1 million in electricity costs and 11,000 metric tons of CO2 per year in Broomfield, helping the company reduce its carbon footprint by 6 percent in the U.S.

The new Broomfield datacenter follows similar Sun projects completed in Blackwater, UK, Santa Clara, Calif. and Bangalore, India in August 2007.

The Broomfield datacenter is based on Sun's Pod Architecture and energy-efficient SPARC and x64 servers, Open Storage and tape products and the OpenSolaris Operating System. In one example, Sun consolidated 63 servers and 30 direct attached storage devices to two Sun servers.

Features of the new Sun Broomfield datacenter include:

  • Greater space efficiency: A scalable, modular datacenter based on the Sun Pod Architecture led to a 66 percent footprint compression, by reducing 496,000 square feet from the former StorageTek campus in Louisville, Colo. to 126,000 square feet;

  • Reduced electrical consumption: By 1 million kWh per month, enough to power 1,000 homes in Colorado;

Wintegra and PMC-Sierra Team on T1/E1 Transport over Carrier Ethernet

Wintegra introduced its first platform dedicated to Carrier Transport applications that include essential support for the emulation of up to 336 T1/E1 circuits with independent clock domains. Wintegra's new Multi-Service Access Platform includes PMC-Sierra's PM8310 TEMUX 336 framer solution plus its own UFE3 and WinPath2 access processor.

The fast deployment of Carrier Ethernet and MPLS networks requires means of transporting SONET and SDH data using pseudo-wires. Wintegra said this can be achieved in two ways, either using one pseudo-wire for each Synchronous Payload Envelope / Virtual Container (like STS-3c or STS-12c), as described in RFC4842 (Synchronous Optical Network/Synchronous Digital Hierarchy Circuit Emulation over Packet), or by using multiple pseudo-wires that each transport one T1 or E1, using SAToP (Structure-Agnostic Time Division Multiplexing over Packet), as suggested in RFC 4553, RFC 5086, Y.1413 and Metro Ethernet Forum Technical Specification 8 (MEF 8).

The second method, implemented by Wintegra, has the advantage that the packet network can implement an implicit Add-Drop Multiplexer functionality, where individual T1 or E1 circuits can be easily inserted or removed in the Synchronous Payload Envelope / Virtual Containers, by switching them in the packet domain. With the first method, to achieve this, it is necessary to interwork from packet to SONET/SDH, use an Add-Drop multiplexer and then interwork back to packet.

However, the second method is also more challenging to implement, since each T1/E1 can have an independent clock. The need for independent clocks comes from applications where customers lease one or more T1/E1 lines and use asynchronous clock sources to drive the T1/E1 line clocks. In some cases, as an example when the T1/E1 lines are used for Wireless Backhaul, many lines can share the same clock source, since many of them can be connected to the same Radio Network Controller. However in other cases, like Enterprise Access, it is possible for each T1/E1 line to be leased by a different user and hence have an asynchronous clock.

For this reason, and to simplify the management of the SONET/SDH to packet interworking function by not having to define different clock domains, it is necessary to support as many as 336 Differential Clock recovery domains for an OC12 interface.
