It's Expensive

idea posted by Vikas Garg Project Manager, ITC Infotech
This is a major misconception, I admit that the initial cost of a mainframe is a bit high, but the TCO is very good, total cost of ownership of a mainframe is better than mid-range machines and PCs, because it is more reliable and scalable.

It is not Green

idea posted by Joseph Abraham PM, Infosys
The biggest misconception is that mainframes are energy-inefficient. It is said that 1,500 x86 servers would be needed to provide the processing capacity of a z10 mainframe - yet the z10 would consume 85% less energy. So mainframes are more green than any other.

IBM Monopoly

Well, it's true to certain extent cuz nowadays all the processors are made by IBM. However, when you're looking for suppliers of DASD, tape, printers, communication devices, then the choice is huge. And in terms of software, yes you need IBM's operating system, but after that, there are plenty of choices.
