FOCUS NETWORKING UPDATE
UP 10G, 40G AND 100G PORTS The uptake of high-speed 10G, 40G, and forthcoming 100G optical and Ethernet ports on enterprise and service provider equipment continues to accelerate despite global economic difficulties.

service provider ports jumped 38% in 2009 while worldwide revenue totalled $11.1 billion in 2009. The number of 40G ports shipped on enterprise and service provider equipment doubled in 2009.
The company predicts that the strong growth in the high-speed port market is set to continue with the combined 10G, 40G, and 100G port shipments increasing 10-fold from 2009 to 2014. “While worldwide spending on service provider IP edge routers declined overall in 2009, spending on high-speed 40G ports on IP edge routers increased 125%,” notes Michael Howard, principal analyst of Infonetics Research. “A similar trend is playing out in other routing and switching segments and in the optical network hardware space. This is the clearest indication yet that service providers are turning to higher-speed options for their next-generation networks to handle skyrocketing traffic.” Matthias Machowinski, directing analyst for enterprise voice and data and co-author of the report, adds: “Revenue from 10G port shipments to enterprises grew 32% in 2009, to $1.5 billion. Despite the significant pullback in overall investments in 2009 - for example, Ethernet switch sales fell 19% in 2009 - investments in high-speed networking devices increased as enterprises continued building out their core network infrastructure to respond to growing levels of traffic.”
Storage company EMC is pushing ahead with its convergence networking drive by unveiling a new strategy, products and partners. It has inked deals with both Cisco and Brocade to resell their switch technology Over the next few months, EMC plans to introduce an expanded portfolio of converged networking services for Ethernet environments, including network assessment, planning, design and implementation services. These will support a range of protocols – including Fibre Channel over Ethernet (FCoE), Converged Enhanced Ethernet (CEE), iSCSI and Network Attached Storage.
There will be an enhanced suite of tools to assist with the sizing, analysis, design and migration to converged networks. EMC is also planning a major investment in training its staff in Ethernet-based networking and storage skills.
On the technology front, EMC will start selling a full range of Brocade 10 Gigabit Ethernet (GbE) switch products, as well as a data center system solution based on certain Cisco Nexus 10 Gigabit Ethernet (GbE) switches.
Charles King, principal analyst, of Pund- IT, Inc. said “Customers will look to those vendors who can put together packages that advance new IT strategies while also leveraging existing data center investments.”
NEW RDMA OVER CONVERGED ETHERNET STANDARD ARRIVES
A new data center networking standard has been introduced that promises to reduce latencies, increase energy efficiency and reduce the amount of cabling in Ethernet- based data centers. The new RDMA over
Converged Ethernet (RoCE) standard, pronounced Rocky, allows for Remote Direct Memory Access I/O architecture to work over Ethernet. RDMA allows connecting memory of one server with that of another without the use of either machine’s operating system, which results in greater efficiency in compute clusters and storage systems. The new standard can be implemented in 10G and 40G Ethernet clustering and can deliver all three types of unified networking on Ethernet: IPC, NAS and SAN.
Introduced by the InfiniBand Trade Association (IBTA), RoCE can produce energy savings and reduce the footprint of Ethernet-based data centers by reducing the number of servers needed, eliminating cabling and improving application performance. It has a “one fat pipe” approach to server I/O which gives administrators greater flexibility in deploying applications and, IBTA claims, complements the virtualisation strategies being deployed today. Products using RoCE will start arriving next year.
“RoCE addresses a key concern of the enterprise – maximizing and protecting current investments in IT,” comments Cindy Borovick, research vice president, Datacenter Networks at IDC. “RoCE leverages field- proven RDMA, ubiquitous Ethernet and fabric management solutions. This will benefit data center network end users by consolidating data, storage and clustered networking and reducing costs.”
Asaf Somekh, vice president of marketing at Voltaire and member of the IBTA Steering Committee, adds: “The new RoCE specification, with a purpose-built and proven RDMA transport, provides the most efficient and light-weight transport over Layer 2 Ethernet. RoCE is expected to enable the enterprise data center to serve more clients with a broader range of applications – all while providing faster response times and reducing the number of servers, cables and switches required.”
