Mainframe 101
Part One

We want you to know a bit about the machine and the z/OS environment you will be interacting with during the course of this contest.

The IBM z13 is the latest and greatest Enterprise-class server available and the role it plays in modern business cannot be understated.

Many of the world's largest companies process their mission critical production data on a mainframe. They chose the mainframe because of its excellent performance in reliability, availability, and serviceability (RAS). Even when parts of the mainframe inevitably fail during operation, the redundancy built into the machine ensures that important business processing can continue uninterrupted.

z Systems has an amazing history with lineage that has spanned the past 50 years. z13 is the culmination of unparalleled technical advancements and innovation of this unique computing platform we call the mainframe.

The z Systems hardware that hosts this contest is one of the most matured, reliable, flexible, secure, and function-rich platforms on the planet. The mainframe is a massive server with patented technology not found in any other computing platform on the planet.

The mainframe is the best platform for transaction processing, consolidated and secure data warehousing, and hosting enterprise-wide applications. With hardware and software optimized for high RAS, it's no wonder that 96 of the 100 largest banks, 9 of the 10 largest insurance companies, and 23 of the top 25 US retailers all rely on the mainframe to perform the mission critical processing that keeps their businesses running.

The z13 hardware can be logically carved into 85 separate partitions called LPARs (Logical PARtitions). LPAR technology enables secure multi-tenancy through which many different operating systems can be running on the same machine at the same time. z Systems LPAR is rated at Evaluation Assurance Level (EAL) 5+, making it the most trusted general purpose computing platform on the planet.

Do you care about the environment? Consider the impact carbon emmisions is having on the environment. The mainframe enables consolidation of many smaller servers leading to greatly reduced power consumption, reduced physical data center space, and reduced cooling requirements. Just think about it: you are helping to save the planet with your mainframe skills!

From legacy to Linux, assembler to node.js, console to cloud, the Mainframe does it all.
