Network convergence and economic infrastructure

While selecting the right network components can help to support energy – efficient operations throughout the data centre and LAN, there is much more to going green. It is really about smarter working across all systems within a facility. That's where IP convergence comes in.

ETHERNET AND IP have advanced to the point where it can now be used to transmit voice, video, security, industrial control and building management information across the network. Where facilities once had several proprietary systems running over their own cabling to their own equipment, IP convergence allows several building systems to run as open networks that use the same cabling media and send data signals using a common protocol. This eliminates a lot of unnecessary cabling and material.

For example, many hospitals used to deploy separate coax networks for delivering TV and entertainment to patient rooms and waiting areas and another copper network for delivering Internet access and telephony. With IP convergence, data from various systems can be centrally managed from one interface vs. separate equipment and more easily shared between applications for simplified building operations.

Critical alarms and notifications from life safety systems can interface with the corporate LAN and phone system to send alerts to PCs and cell phones of those responsible for facility management. The possibilities are endless.

Total IP convergence is not yet a reality, and many systems are still deployed separately. However, as this way of designing and deploying building systems comes to fruition, it will ultimately result in overall simplified, efficient operations that significantly reduce waste and produce green, sustainable facilities.

Green physical layer components

• Heat containment systems can provide up to 50% energy savings when compared to standard hot aisle/cold aisle and enable 100 percent utilization of existing cooling infrastructure by efficiently managing   airflow and providing hot aisle/ cold aisle containment.

• High density racking systems can provide a 60% reduction in floorspace requirements while enabling scalability and easy reconfiguration.

• Power and thermal management products save space, monitor and control temperature and deliver efficient three phase power distribution to the cabinet for better load balancing, increased airflow and reduced material usage.

• High performance 10/40/100 gigabit Ethernet cabling systems offer top performance and longer lifecycles to reduce the occurrence of product obsolescence. Systems with smaller diameter cables enable higher densities, or space savings, and improved airflow for energy efficiency.

• Pre – terminated optical fibre and copper cabling systems significantly reduce installation and waste, provide up to 40 percent material reduction, offer high density for space savings and ensure a longer lifecycle due to performance and reusability.

• High density patch panel systems maximize space and provide scalability, while angled patch panels reduce space takeup by over a quarter per rack, and facilitate intuitive cable management and improved airflow.

• IDC systems reduce the floor space requirement and improve material usage due to crossconnect cable vs. patch cords.

• Fast, simple to use fibre – optic field installable connectors can significantly reduce installation labour and waste on site.
