The AS/400 iSeries lives on as Power8! Many people are familiar with those designations for IBM’s midrange systems. All of those have become what is now known as the IBM POWER8 system running iOS. The AS/400 has come a long way since its inception and initial release in 1988. The family can go from small desk-side single system units all the way to large mainframe-sized multiple-rack systems. They can be used in everything from small businesses to large multinational corporations to manage their data and day-to-day operations, inventory, sales, payroll, time reporting, accounts receivable and accounts payable needs. In addition to all that, they can be used to host a company’s website and all that comes along with that.
The backbone of this family of systems is the operating system currently known as IBM i, formerly known as OS/400. This operating system possesses legendary reliability and security. It comes fully integrated with its own database and almost manages itself. With logical partitioning, you can easily have several partitions running independently as autonomous systems under the same covers. It also has the capability to run VIOS (virtual I/O server) logical partitions to enable virtual sharing of physical hardware resources between partitions. This saves money as there is less physical hardware to purchase. In addition to all of the above things, you can create an AIX LPAR as well as Linux.
There is a common misconception that the i OS is antiquated simply because most people use green screen. Such is not the case. There is a point and click GUI called Ops Navigator on which you can do any and all functions on the system. It looks basically like Windows. It would solve any green screen dissatisfaction issues.
In closing, I would say that if you get an opportunity to speak to anyone from an iOS shop, no matter whether it’s POWER 5, 6, 7 or 8, do so. You’ll find a that they are very dedicated users and would not easily be talked out of using this fantastic, stable, secure system. They would explain to you how it is a workhorse that just runs and runs and runs. You’d probably be amazed at how much of the world’s companies rely on this system for their business.
