The addition of 2.5G and 5G Ethernet link protocol speeds in the wiring closet will enable the cost-effective scaling of network bandwidth to enterprise access points and provide IT professionals with more data-rate options.
* 25G, 50G and 100G in the Data Center. Enterprise and cloud network operators must build out their networks following carefully planned technology roadmaps that scale according to changing needs. As always, these operators will have to balance performance optimization while maintaining the lowest possible capital and operating expenditures (CAPEX/OPEX). One way to accomplish these often-conflicting goals is by transitioning to higher-speed Ethernet technologies.
Experts predict that the largest cloud operators will shift to 100G Ethernet fabrics while cost-efficient 25G and 50G will remain the workhorses for most of the other well-known data-center companies. The 25G/50G Ethernet Consortium a relatively new body has made its 25G and 50G Ethernet specification open to all data center ecosystem vendors - royalty free - to create and deploy compliant, interoperable product implementations. The standard should hasten the widespread deployment of 25G and 50G Ethernet ports that will coincide with the rollout of 100G Ethernet for cloud fabrics.
A 25G/50G standard may seem like a step backward, because 40G and 100Gbps Ethernet already exist, but it's all about the need for more cost-effective speed, specifically from servers in cloud data centers. For example, 25Gbps cabling is about the same cost structure as 10G at 2.5X the performance. Similarly, 50G is half of the cost of 40G with a 25-percent increase in performance.
* Cloud Scale Networking. How can companies drive down the cost of mobile networking while driving up efficiency and flexibility of their IT infrastructure? The virtualization of networks, storage, and servers is reshaping the way organizations use IT. Cloud computing plays an essential role in this process, providing Internet access to complex applications and massive computing resources.
The cloud delivers the additional capacity required to satisfy growing demand to an enterprise or small business from a third party, giving organizations a way to crank up capacity without investing in a new IT structure. Being able to host processing and data in the cloud frees network administrators to relocate that capacity to geographic locations where the data is being created, as well as control the devices generating the data. A well-designed Ethernet network delivers the low latency and high bandwidth required by cloud computing to deliver the full value of its efficiencies.
* Open-Source Networking. Cloud scale networking is useless without software — every switch needs an operating system. Software must deliver a hardware-agnostic network operating systems that enable an abstraction layer on the merchant-based switch silicon, just like Linux and Windows provide on the server side.
