Mainframe Cost

What is the Average Cost per MIPS or MSU? Who Cares!

The title of today’s post is a question that I get asked all the time. Sometimes by users who are interested in trying to curtail mainframe costs. Sometimes by vendors looking for a way to promote their products that help to reduce costs. While both are well-meaning, this is a question I never answer. Because it is meaningless. Let’s discuss why this is so. First, let’s look at some of the “answers” to this question

Planning a Successful Shifting COBOL Compute Project Now Available on YouTube

As mainframe costs continue to rise, alternate compute and execution environments such as the zIIP, Linux, and the cloud are gaining more attention and credibility. Using cross-compile techniques to transform COBOL systems to Java creates opportunities for application owners and IT management to explore and prove the economics of hybrid environments that leverage less expensive execution. While IT organizations are getting comfortable with hybrid environments for enterprise applications, most still need to pull their mainframe

The Many Types of Mainframe Pricing

Whenever somebody talks about software pricing on the mainframe or tuning to save on their monthly mainframe bill, I always wonder just exactly what they are talking about. Are they aware of all their company’s licensing agreements and all the intricacies therein? Before we move on, let me just state that the mainframe still makes good economic sense. The total cost of ownership (TCO) for the mainframe, when you add up all of the cost

The Last MSU is the Cheapest

The cost per MSU (or MIPS) is not steady. At least not for sub-capacity pricing. As the number of MSUs or MIPS  you consume increases, the cost per/MSU (MIPS) goes down. This means that each MSU (or MIPS) saved will be the cheapest you are paying for. This can be verified by reviewing the IBM Z Software Pricing Reference Guide. The price per MSU is based on a multi-level system unique to the sub-capacity pricing

The Whack-a-Mole Effect: Tuning Mainframe Usage for Cost Savings

There are many reasons for tuning your mainframe applications. Surely the most important reason is to provide faster access to your end users. The quicker an application responds, the happier the people that use it will be. But a close second is likely to be cost reduction. Unfortunately, tuning to achieve cost savings is frequently undertaken without a good understanding of just how mainframe costs are calculated. Or at least the major contributor to those

Understanding Mainframe Pricing to Aid in Modernization and Cost Control

Cost containment is an important criterion for IT departments as organizations everywhere embrace financial austerity. Every decision regarding your computer resources is weighed based on not only the value that it can deliver to your organization, but upon the cost to procure, implement, and maintain. And in most cases, if a positive return on investment cannot be calculated, the software will not be adopted, or the hardware will not be upgraded. One area that many

What is DRDA? zIIPs and Distributed Db2 SQL

When it comes to exploiting the zIIP specialty processor, a lot of attention is paid to distributed Db2 SQL requests, and rightly so. Distributed SQL issued against Db2 is one of the largest opportunities for reducing stress on general purpose processors. Indeed, most modern applications that access Db2 data do so using dynamic SQL using DRDA. But let’s back up a moment and take a look at some of these terms and what they mean.

Ebook: From A to zIIP Now Available for Download

Specialty processors are an IBM enhancement introduced to mainframes in the early 2000s. These processors augment a mainframe’s general processor, allowing organizations to shift specific workloads off the GPU.  Why do this? While there are many reasons, one rises above all others— cost savings. In this ebook, noted mainframe authority Craig Mullins reveals what you need to know to leverage the zIIP IBM Specialty Processor for mainframe cost savings. Download this eBook if you want

Types of Processing That Can Utilize zIIPs & Why You Want to use zIIPs

In our last installment of this series on IBM zIIP processors, we defined what is meant by zIIP eligibility. We took a look at specific types of workloads that IBM has made zIIP eligible. This post will dig a little deeper into what makes a workload eligible for running on zIIPs. And we will also take a look at why you would want to exploit zIIP processors for your workloads.  TCBs and SRBs To fully

Understanding Mainframe Specialty Processors: zIIPS and more

If you are an IT professional who works on IBM z Series mainframes, then you’ve probably heard about zIIPs and other “specialty processors.” But you may not really know what they are, what they do, and why they exist. With that in mind, let’s take a brief journey into the world of specialty processors. Starting in the early 2000s, IBM has introduced several different types of specialty processors. The basic idea of a specialty processor

Upcoming Webinar: Measuring the Impact of Shifting COBOL Compute

Upcoming Webinar: Measuring the Impact of Shifting COBOL Compute

Shifting COBOL compute to less expensive platforms may be the best first step on the modernization journey. Identifying and moving the execution of your most expensive COBOL batch jobs provides an opportunity to reduce cost or free up funds in an existing IT budget. This modernization technique offers a low-risk, straightforward, and cost-effective approach that […]

Common Shifting COBOL Compute Mistakes

Shifting COBOL compute to less expensive platforms is a great first step on many organizations’ application modernization journey. There are multiple reasons an organization might want to begin with shifting COBOL compute, including low risk, the straightforward nature of the approach, and the potential for extraordinary ROI. NOTE: Cross-compiling COBOL programs into Java byte code […]
