The unknown microwave networks

Recently, it became known that there is a private, mysterious network stretching between London and Frankfurt that is twice as fast as the normal Internet. The connection, provided by a series of microwave dishes on masts, was completely secret to anyone but one company. Only when a competitor completed its own microwave link between the two cities, the first company revealed that it too had a link between the cities in order to get a share in this potential market.
Similar stories can be found all over the world, but because these networks are privately owned, and because they are often used by financial groups trying to find an edge on the stock market and eke out a few extra billions, you have to investigate hard to find them.
Hyper-Converged Needs to Get Beyond the Hype

It used to be that, when you bought a server with a NIC card and some internal or direct attached storage, it was simply called a server. If it had some tiered storage – different media with different performance characteristics and different capacities – and some intelligence for moving data across “tiers,” we called it an “enterprise server”. If the server and storage kit were clustered, we called it a high availability enterprise server. Over the past year, though, we have gone through a collective terminology refresh.
Today, you cobble together a server with some software-defined storage software, a hypervisor, and some internal or external flash and/or disk and the result is called “hyper-converged infrastructure.” Given the lack of consistency in what people mean when they say “hyper-converged,” we may be talking about any collection of gear and software that a vendor has “pre-integrated” before marking up the kit and selling it for a huge profit. Having recently requested information from so-called hyper-converged infrastructure vendors, I was amazed at some of the inquiries I received from would-be participants.
