Mainframes and System z in Today's IT


If think of the ubiquitous platform for Linux, most likely you will think of x86. It is, after all, the platform upon which Linus Torvalds first created his enhancement of Minix and certainly the most commonly installed processor in the Linux world.

If you are using seriously heavy workloads, you would be forgiven for thinking that you’d need to set up a Linux cluster of machines or a cloud set of instances to get the job done. And you would not be wrong.

But there are other technologies out there that can do the job of a collection of x86 Linux machines – sometimes, even better. Consider the mainframe, which can still provide massive processing power, ease of management, and security. “Mainframe” may sound old-fashioned in the world of cloud computing and the Internet of Things, but there will always be workloads that are better suited for mainframe platforms.

This is why SUSE Linux Enterprise Server for System z is one of our product offerings – because customers sometimes need the faster performance, tighter security, better resource utilization, and reduced administration you can get with server consolidation.

If you are interested in learning more, The Register is hosting a Regcast on Critical Linux Workloads on May 22 at 1000 BST. The topic will focus on Linux on IBM’s System z, and the crew at El Reg will be “joined by IBM’s John Easton and Tony Lock from Freeform Dynamics, perhaps the last living analyst to recall when mainframes were all there were.”

It should be interesting viewing, where you can hopefully learn more about the very real benefits of System z.
