There may be affordable solutions coming for transporting storage mirrors and archives over longer distances.
From the Wall street Journal
""We can no longer rely on last-generation technology, which has essentially remained unchanged for 40 years, to power Internet performance," says Mr. Roberts, who is 69 years old. Last month, his start-up, Anagran Inc., introduced a piece of gear called the flow router that he says can help modernize the Internet. The equipment analyzes Web traffic to discern whether it is an email, a movie or a phone call and then carves out the bandwidth needed for transmission."
"Mr. Roberts isn't the only networking pioneer dissatisfied with earlier achievements. Len Bosack, the 55-year-old co-founder and former chief technology officer of networking giant Cisco Systems Inc., helped commercialize routers, the core piece of networking equipment that allows computers to communicate with one another. Yet he now terms such gear "less and less adequate" for today's Internet needs. Last month, his company, XKL LLC, unveiled a system that allows businesses to connect to underground cables that have nearly 100 times the capacity of current telecommunications pipes."
Is there a possibility that these companies can work with large storage users to make affordable mirrors possible?
