Infinera — a provider of intelligent transport networks — recently unveiled Cloud Xpress, a platform designed for network operators delivering cloud-based services to consumers and businesses worldwide.
As cloud adoption increases, large network operators are reporting a magnification effect on incoming traffic, said Vinay Rathore, Infinera's senior director solutions marketing, at a media briefing in Hong Kong. He explained that a single request from an end user can generate up to 10 times the amount of traffic between data centres than what was contained in the request.
This magnification effect is accelerating the deployment of high-capacity transport solutions into the metro cloud. Metro cloud is a transport network that interconnects multiple data centres within a relatively small geographical area of around 200km. By doing so, service providers are able to offer high-bandwidth networking at relatively low costs.
To help network operators cope with the magnification effect, the Cloud Xpress simplifies the deployment of high bandwidth connections while lowering the power and space required to scale metro cloud networks.
Simplified operations and low power required
Rack and stack is not uncommon for a cloud operational model. "As customers are used to stacked blades for servers and racked units for storage, they want the same form factor for networks," said Rathore. Cloud Xpress thus comes in a small, stackable platform to address that demand.
To simplify the implementation process, the Cloud Xpress also comes with a software that enables it to plug into existing cloud provisioning systems using open software defined networks application programming interfaces (SDN APIs). This ensures smooth integration into existing operational processes, enabling cloud providers to quickly scale, reduce human errors and lower operational costs.
In terms of power required, Rathore said that the Cloud Xpress only requires around 130W per 100G. This is 50 percent less than transport solutions offered by category leader, he added.
The Cloud Xpress delivers one terabit per second (Tb/s) of input and output capacity in two rack units, with up to 500 gigabits per second of line-side capacity and a mix of 10 gigabit Ethernet (GbE), 40 GbE and 100GbE client-side interfaces. Cloud Xpress is thus ideal for network operators that need to scale the metro cloud in the least amount space. This is because it delivers 21 TB/s of input and output capacity per 42 rack units rack.
Even though the Cloud Xpress is currently undergoing customer trials, Infinera is taking orders for it now and plans to launch it to the masses in December 2014.
Since the metro cloud is growing at a healthy rate, it is forecasted to make up around 24 percent of the US$18 billion optical cloud market by 2019, projected ACG research. It is thus the right time to bring 100Gb/s solution such as Cloud Xpress into the market, said Andrew Bond-Webster, Infinera's vice president for Asia Pacific.
