When a 40 Gbps server may be applied?

It’s a widely acknowledged fact that the future of Internet connectivity mostly depends on the changes in the manner in which we organize data centers. The speed and quality of connection depend on a physical layer of server, and 40 Gbps servers are gradually becoming the new standard for web-masters and enterprises that play big. Let’s find out how a 40 Gbps server works, and when this solution can come in handy.

Technical characteristics of 40 Gbps connectivity

As its name suggests, a 40 Gbps server works at a speed of 40 gigabits per second. Such Ethernet solution typically supports five kinds of ports that offer link distances stretching from 1 meter and up to 10 kilometers. Using 40 GBASE-R encoding, 40 Gbps connections require four lanes working with 64B/66B scrambled encoding type. These connections are compatible with two major types of electric links: 40GBASE-KR4 and 40GBASE-CR4.

A system that works with 40 Gbps connectivity may also work via 3 optical links including 40GBASE-FR, 40GBASE-LR4 and 40GBASE-SR4. As for the number of cables, 40 Gbps connection requires eight fiber cords with a standard QSFP connector.

40 Gbps: the new standard of connectivity

I/O data transfer rates at access layer double every two years, and transfer rates at the core layer double every 18 months. The primary driver pushing 40 Gigabit Ethernet is a new generation of computing technologies and applications with a high demand and high speed. These include implementation of cloud computing and virtual servers.

By 2009, nearly every 5th server was virtualized, while financial pressure of economy forced network developers to search for ways to unite their resources to cut on the total cost of ownership. 40 Gbps Ethernet is the next step in development of data networks. The drop of prices helped market researchers to predict that the shipments of optical market would reach $14.5 bln by 2013. The market of 40 Gbps servers alone reached $3 bln in 2016, and this number is expected to grow faster.

Although the new Ethernet standards will influence every aspect of network, the major demand comes from servers: they comprised 40% of 40/100Gbps Ethernet market in 2016.

The demand for 40 Gpbs dedicated servers grows

Dedicated servers with 40 Gbps ports are perfect for dealing with various bandwidth issues and can be applied on various business verticals. The experts claim that the demand for new Ethernet speed will first come from large data and switching centers, computing environments with high performance and Internet exchanges. Anyone who uses 10 Gbps Ethernet is likely to switch to 40 Gbps server ports as soon as they become more affordable and available.

The spheres of application of 40 Gbps Ethernet are expanding. While 10 Gbps Ethernet is still being implemented in data centers, CIOs and IT managers should already consider how to handle the traffic that comes next. Cloud computing, server virtualization, fabric consolidation and other similar business branches have enormous requirements. The need for faster data transfer is growing exponentially, and it concerns network productivity, as well.

The increased speed lets us promote access to 10 Gbps Ethernet resources allowing for 40 Gbps equipment to handle traffic at core and aggregation layers. According to analysts, the development of 40 Gpbs Ethernet and its wide acceptance is just the question of time. What IT managers can already do is to prepare the network architecture to migrate to the new standard.

Where 40 Gbps dedicated servers can be used?

If you have a well-developed project with a huge amount of traffic to be handled, a 40 Gbps server can become a real magic wand. It’ll provide more than sufficient amount of resources together with strikingly fast connection for transferring terabytes of information.

40 Gbps dedicated servers are already being implemented in the following spheres and projects:

- Video on demands;

- Server virtualization;

- Consumer & broadband access;

- Blade servers;

- Fabric consolidation;

- Service providers and IXCs;

- Data centers;

- High-speed computing;

- Research and development.

Even if none of that is your case, you may consider making a business with 40 Gbps server and lease it to multiple users. The sphere of application is pretty wide, so it’s time to jump on the bandwagon that’s only started its way.
