FC technology use still leads despite Ethernet nipping at its heels

Some observers have predicted the demise of Fibre Channel (FC) technology for years, but no networking tech has risen above it for mission-critical applications. At least two technologies have tried to overtake Fibre Channel (FC) in the past decade: Ethernet and InfiniBand. Both have failed and FC use continues unabated. Why is that happening, and what's the future of FC? Fibre Channel technology is here to stay for many years to come, but the reasons aren't always clear cut. To understand, one has to look back, even past the origin of FC. Defined in 1988, Fibre Channel was designed specifically for high-reliability, high-performance SANs to allow storage to be shared by many hosts running a variety of applications while delivering predictable performance. Because FC was designed strictly for storage, the technology understood the value of data integrity and that data had to be moved with 100% certainty from source to destination. It also provided multi-tenancy while maintaining low latency. These were new concepts that were ...
