The last z System that conformed to the expectations of Moore’s Law was the zEC12. IBM could boast that it had the fastest commercial processor available. The subsequent z13 didn’t match it in processor speed. The z13 chip runs a 22 nm core at 5 GHz, one-half a GHz slower than the zEC12, which ran its 32nm core at 5.5 GHz. Did you even notice?…

Nowadays, most RACF administrators report to Chief Information Security Officers (CISOs) who have never worked with z/OS or RACF, and they are being inspected by auditors, both internal and external, who likewise have had little exposure to the mainframe. The RACF administrators we speak with and those who post messages on discussion forums are constantly saying something like "my (fill-in-the-blank) doesn't understand RACF, and this is causing me endless headaches." To address this situation, we took it upon ourselves to write a brief description of RACF that administrators can pass on to their manager and others within the organization who need a basic understanding of RACF's purpose and function. The following overview is the result. Although the overview has just been published on our website, it has already been downloaded many times, and we have received feedback that it has been helpful. We hope you find it helpful, too…

The research also shows that businesses benefit from having their staff being coached. Although, having said that, there is anecdotal evidence of organizations using coaching in a fairly random way, where HR has no record of who the coaches being used are and what the outcomes of the sessions led to!…

Over 50 years after their introduction, as much as 80 percent of the world’s corporate data still resides on mainframes. They are used by 71 percent of the Fortune 100, and not just for residual workloads that IT departments haven’t yet offloaded into some newer storage and processing system. Mainframes are still incredibly relevant in a rapidly evolving IT landscape – they remain the best option for secure, large-volume transactions, the foundation of many modern technologies. The dwindling number of “IT experts” who say the mainframe is nearing its end are ignoring how it has helped IT organizations and, more importantly, how it continues to support modern-day tech like mobile, cloud and still-emerging technologies like real-time analytics and the Internet of Things (IoT)…

What’s Wrong With the Mainframe?

Something is wrong with the mainframe. Unfortunately, most people don’t realize what it is.

One piece of evidence that something is wrong with the mainframe is the near-total absence of positive media coverage regarding the platform. This is definitely odd given the fact that the mainframe remains the transaction engine of choice for the global economy…

Although friends and family appreciate my enthusiasm for technology, there's nothing like trading ideas with others who share your passion. I recently attended the SHARE conference in Orlando and was, as always, happy to reconnect with the mainframe and enterprise community. I also came away excited by how the event reflects the present moment in mainframes. Here are a few of my major takeaways…

I am excited by several aspects of this announcement: IBM is establishing, in conjunction with the Linux Foundation, an Open Mainframe Project; the company is breaking with its traditional mainframe pricing model; it also is putting KVM and Ubuntu on the machine; and it is offering a smorgasbord of app-dev options, including some of the sexiest in the industry today. I never believed I would refer to a mainframe as sexy (must be time to retire)…
