Mainframes have long been called dinosaurs. Check out this interview where mainframes are compared to elephants and learn how mainframes are much more agile than either dinosaurs or elephants.

 

Happy holidays to you! Have a wonderful 2011.

Mainframes in the cloud

Is the mainframe a cloud?

 

The short answer is “no,” but mainframes and clouds have a lot in common. Clouds have a centralized mainframe-like core with distributed nodes, and they are quite attractive. Some pundits believe that the cloud will bring a paradigm shift as powerful as the Internet. According to recent analyst studies, virtualization and cloud computing are the top priorities of CIOs. Is it time for you to jump on the cloud bandwagon?

 

Virtualization has been a hot topic for years, and it has evolved to become cloud computing. But what was the first virtualized system? The mainframe, of course, over 40 years ago. After all, the mainframe operating system’s middle name was “virtual” (multiple virtual systems – more commonly known as MVS).

Check out this recent research on the real cost of mainframe processing.

 

Dr. Howard Rubin says, "Mainframes can run at 80- to 90-percent utilization or more. Say you have  100,000 MIPS on the mainframe. For that same power, you have 60,000 servers. Servers have a 15- to 25-percent utilization average, hitting dead spots of 3 to  5 percent and peaks in the 60s. Their performance is very much tied to the application, and the utilization isn’t high, even in a virtualized environment. On a unit-cost basis, if you drive down your cost of goods and keep the quality and sell price the same, your profitability is higher and you have better  earnings per share—whether shipping a ton of freight on a railroad or a  passenger mile on an airplane."

 

What is the ratio of MIPS to server processing power in your shop?
