There's more than one way to build a storage-area network.
Vendors continue to announce standards and plans for alternative storage network technologies.
It is safe to say at this point there is not one dominant technology. And many SANs utilize more than one of these connection technologies, further compounding the issue of determining which is best for you. Interestingly, when we question IT professionals about their reasons for choosing their preferred storage network technology, the reasons are often similar, regardless of the technology chosen. It would appear that distinguishing among these alternatives is not an easy matter, or perhaps it is a very individual decision for each implementation. Again, speed is a reason cited for every technology, indicating there is currently no leader.
