Whether you have heard or read anything about the IBM z or not, in this tutorial. We are going to explain beasts you should everything you to know about these processing monsters that IBM still has. In development and that are true dinosaurs in many ways, but that They continue to be. IBM zSystem is the name that the blue computing giant has given to its family of mainframes . These mainframes are on the IBM z/Architecture, and have had a long journey throughout history. From the launch of the z to the present day with the new IBM z, the successor to the z, and in which we will stop in this article. As you well know, IBM is the clear dominant in the world of mainframes , currently being a monopoly, although.
What is a mainframe?
Many may be wondering what a mainframe is that was quite common in the past, but now with server and HPC systems it has been left in the background. Well, it must be said that basically, a mainframe is also Qatar Email List a high-performance computer. Specifically, it is an HPC device for high workloads, with a large memory capacity and processors capable of performing a large number of calculations per second, as well as thousands of simple transactions in real time. On the other hand, it must be said that they are to work with heavy workloads, such as large databases, enhancing the I/O system of these devices. Of course, they have to do it with great skill and with safety guarantees, since they usually handle very critical tasks.
Differences with a supercomputer or a server
The differences between a supercomputer and a mainframe are quite unclear. While supercomputers are the largest and most expensive computers. They are especially to process. A large number of mathematical calculations and complex Hong Kong Phone Number List operations as quickly as possible. While a mainframe is something similar, but they are usually smaller, less expensive and slower. Regarding the differences between a server and a mainframe , some key ones should be. Mainframes are to handle much more data, such as billions of transactions per day. While a typical server database might be handling about transactions per second, which is equivalent to million per day. Mainframes run single software in most cases, with very specific operating systems such as z/OS, and programs written in quite old languages such as COBOL, FORTRAN, etc.
