Issues to consider
| expense) will be required, justifying the investment may be difficult, especially considering the macro environment. However, if the math becomes compelling enough, say below $500 per port, adoption may accelerate.
So why should you be thinking about FCoE now? Products are becoming available--specifically, the Cisco Nexus 5000 and Intel Adapters--and some vendors have made claims that FCoE will be in production environments this summer. Users currently testing FCoE environments using alpha/beta equipment seem quite satisfied with it. With some products available now and more due this fall, I say companies should consider creating a test and development platform for FCoE to become comfortable with the technology. Companies should definitely be planning to include FCoE in their 2009 budget if it isn't already in this year's.
What will be the role of Fibre Channel going forward? Saying that FCoE will be the end of Fibre Channel makes for good headlines, but the reality is that FC is here to stay, at least for a while. The Fibre Channel Industry Association continues to drive toward 16Gig FC. Fibre Channel will co-exist with FCoE for a number of reasons. FCoE still needs to be tested and proven, and FC will continue to deliver services until then. Given that data centers are very slow to change--with plenty of people taking the "If it ain't broke, don't fix it" position--adoption could take a while. Lastly, there will always be protocol zealots resisting any new technology. It should be noted, however, that FCoE was designed to co-exist with FC and these technologies will work with existing management tools.
The green impact of FCoE is a compelling factor. The combination of lower power and cooling requirements (not from the protocol, but from the reduction in equipment) with reduced cabling will certainly be attractive as greater emphasis is placed on green initiatives.
You could also consider FCoE the beginning of the end for the cultural barriers that exist between technology domains in large-scale data centers. At the very least, it provides the storage team with an opportunity to get to know the networking team so they can work together to provide higher levels of service to the business and reduce costs. Ultimately, it could provide an opportunity to embrace the sort of change that delivers significant benefit to the business.
