Companies like Corning (GLW) like to tell data center managers that with the advent of 10G, they should be transitioning their network from mostly copper connections to all fiber-optic. But, as many of you probably know, this is easier said than done. There are many things to consider:
1. How much more is it going to cost me to install fiber instead of copper?
2. Do I change my network architecture to Top-of-Rack in order to facilitate using more fiber? What are the down sides of this?
3. Is it really cost-effective to go all-optical?
4. What is my ROI/IRR if I do go all-optical?
5. Will it really help my power and cooling overload if I go all-optical?
It is very difficult to get to specific answers for a particular data center because each one is different. And guidelines from industry vendors may be skewed based on what they are trying to sell you. OFC/NFOEC management has recognized this and asked me to teach a new short course for their 2011 conference – Data Center Cabling – Transitioning from Copper to Fiber will be part of the special symposium Meeting the Computercom Challenge: Components and Architectures for Computational Systems and Data Centers. I invite your ideas on specifics you would like to see covered in this new short course.
