The need to simplify data center networks, supplemented by dwindling prices has made 10 Gigabit Ethernet (10 GbE) a compelling network option for IT managers. From the time 10 GbE first made its entry into the market, active equipment prices have come down by almost 15%. As more suppliers begin to offer 10 GbE, the prices will drop further. On the cabling front, 10 GbE offers an even more attractive option since cabling prices have come down by almost 50%.
It is evident that 10 GbE is the future for wired LAN deployments. However, there are certain mistakes which are bound to happen if you are thinking of taking the 10 GbE route. Let's take a look at how you can avoid the most common 10 GbE implementation mistakes and save yourself future grief.
Avoid buying untested equipment to save a few bucks: Yes, it's very easy to opt for the cheapest 10 GbE solution and show it on your savings sheet. But, remember that this comes at the cost of performance. The biggest mistake that you can ever make on the 10 GbE front is to use equipment or cabling from a low-end manufacturer which has not confirmed or tested its solutions before the sale.
Go the whole hog on cabling: Don't cheat if you want the best out of your investment. For example, if your cabling is a mix of Cat 6a compliant and Cat 6 cabling to save on cost, you will not be able to extract the most from your 10 GbE setup.
To avoid these pain points, the manufacturer or system integrator should look at your project site and ensure readiness to face installation challenges. Infrastructural changes are imperative during a 10 GbE implementation. On the cabling side, Cat 6a is the ideal cable for 10 GbE.
When you install Cat 6a, cabling design is a bit different than is the case for Cat 6 cable. In the case of Cat 6a, you require a different way of looking at cable management. Use of Cat 6a typically means that you will be able to install only a lesser number of cables in the same conduit, same tray or same pathway (than is possible for Cat 6). You should also consider congestion and bend radius, as well as management of cables to the outlet or the back of the patch panel.
Not much has changed when it comes to patch panels and patch cords for 10 GbE. Hence, the important considerations should revolve more around the right size and route for better cable management.
