network interface cards appeared with the common SFF-8470 cabling handling different interfaces in one box or rack. Then there were high port count multi-protocol chips. Now the protocols run through one slimmer QSFP+ or SFP+ cable assembly using one transport layer. In some Solid State Drive devices,


the Fibre Channel and SAS or SATA and USB interfaces are integrated into a single chip. Apparently many wireless interface people are working on their Camelot next generation convergent interface as well. We can only guess how long it will


take new data centre power and cooling requirements, as well as disruptive CMOS Photonic technologies, to


impact further convergence and wide market acceptance. What we do know is that convergence technologies and interfaces will be the big growth factor over the next few years.


Conclusion


If you’ve made it this far through the interfaces and acronyms, you’ll see that there’s a world of complexities, prophecy and manoeuvring that will affect network infrastructures in the years to come. The best bet is to plan for advances


that have a greater chance of coming to fruition - those that have at least shown signs of stability. How you identify these is a matter of personal


comfort level. If your organisation is just transitioning to Gigabit Ethernet, you may not need to worry about preparing for 100 Gigabit-per-lane optical interconnects just yet. If you are responsible for a financial trading floor network, where milliseconds equal millions of pounds, you may want to keep a closer eye on what’s coming after 40 and 100Gbps. If you take only one thing from


this article, it should be this: History clearly shows that network speeds will continue to increase exponentially, and today’s work on next-generation speeds more than supports that concept. Look forward to a reasonable horizon and be prepared.


Redetec is the leading 19” Rack Mount Cabinet Fire Detection and Extinguishing System on the global market, providing localised fire protection to the most valuable assets within the data centre comms room, eliminating the threat to business continuity due to fire.


Fire Protection Where It Counts: Redetec puts fire protection at the point of greater risk; for faster detection & fire suppression; ensuring continuous asset availability & protection.


Budget Friendly: Cost Effective Solutions:


Why protect a whole room when you can concentrate on protecting high risk, high value, equipment. Redetec uses less extinguishant gas and moves with the rack with no need for re-installation.


Redetec solutions do not need extensive design calculations, room strengthening or costly wiring.Installation, commissioning and maintenance costs are all reduced in a more cost effective solution.

The traditional method of fire protection of IT & electronic equipment is to totally flood the room with a gaseous fire extinguishant. Whilst adequate in many situations, there are occasions where faster, more responsive detection is required to protect the high value and mission critical systems on which the company relies. Companies also prefer to use extinguishant gas more carefully and in smaller amounts, demonstrating a more responsible environmental policy as well as reducing project costs.


Redetec provides fire detection and extinguishant release within the protected enclosure, where a fire can be detected early; and where fire extinguishants can be applied directly.
