Since the days when processor time was costly (and you input a job on punch cards), the CPU Busy metric has had intense focus. There are so many ways to look at the metric, all having vastly different meanings. Virtualization made it even more complicated. But for many in our field, this is still a very critical number. But is it the most important number?
Many datacenters are enjoying the software savings provided by ThruPut Manager’s Automated Capacity Management (ACM) component, a safe and selective method to reduce MSU consumption and resulting MLC costs. Now, ACM introduces a significant enhancement – LPAR Sets.Monthly License Charges are implemented on a CPC basis, but each LPAR may contribute to the total in different ways with different software stacks, varying business requirements, or various MSU costs for each LPAR. We are now introducing LPAR Sets to give you more granular control over your batch workload.
A guest post by Denise P. Kalm – When BMC Software releases the results of its latest survey showing that 90% of the participants are confident in a long-term future for mainframes, you have to listen. Or more importantly, the management teams who keep trying to move off of it needs to read the report. While security and availability are frequently cited as important factors – who has hacked a mainframe lately – too often forgotten is the unequalled ability to manage costs on this platform.
Very often, with distributed systems, the cost is the cost; you pay for seat licenses or for the total capacity of the box or some other immutable metric. And let’s not forget the lower availability statistics, nor the fact that Wintel boxes are the biggest targets for hackers. But back to cost, because every systems programmer has had to become an active participant in managing and reducing costs. Which platform is the most flexible in terms of cost?
If you take advantage of IBM’s variable workload license charges (VWLC), you’re more than familiar with the challenges of keeping costs low. In all likelihood, due to the complexity of how the rolling-four-hour-average (R4HA) is calculated, you find out the good or bad news only after you get your bill. You probably have IMS, CICS, DB2 and more running in a variety of LPARs with demand fluctuating throughout the day. And even if you keep your eye on your monitors, looking at the online work may give you a false feeling of confidence about how well you’re managing.
Just as IBM helped customers with CPU costs by offering zIIP engines, it’s again stepping up to the plate to make the cost of mobile applications more affordable. The company’s new program, highlighted in a previous post, is designed for z/OS customers running such programs as CICS, IMS and DB2 with IBM’s new Mobile Workload Pricing program (MWP). The new program allows those implementing sub-capacity AWLC, AEWLC or zNALC to run a new tool, the Mobile Workload Reporting Tool (MWRT), which acts like SCRT but for mobile workloads.
When it was first introduced, IBM’s sub-capacity pricing was a boon for capacity planners from a financial standpoint—allowing them to be more proactive in their planning. In the pre-sub-capacity era, all upgrades had to be carefully managed because of the huge potential impact on software pricing. Now, you can right-size your hardware and worry less about software costs—until you hit a soft cap, that is.
A guest post by Denise P. Kalm – Super heroes abound in cinema and on TV. Batman, Superman, Iron Man and even Ant Man return on an annual basis recycling plots and themes and yet, people stream to the theater to see them again and again. Why? I think it’s because we all secretly want to be heroes in our own lives. Seeing others achieve what few can is inspiring; it makes you believe it’s possible, at least while you’re caught up in the story.
Then we go back to work. Where once, companies bought hardware on your say-so, now the pressure is on to save money and reduce costs while delivering even better performance with increasing workloads. By now, you’ve found all the easy wins–the quick-hit savings opportunities. Where else can you look? Those who can meet management’s directive to accomplish these tough goals will be IT super heroes, and you’d like to be the one who pulls it off.
