Consultation available to identify the optimal solution that will meet business and IT requirements No need to purchase or manage servers, system software, storage or network equipment. Hardware and software components are built to create a stable, secure, fault-tolerant, and scalable infrastructure Customers focus on supporting their application product, not the hardware or operating system.
Disk Administration CDT monitors and manages the disk space. Backup Full merge backups occur once per week and incremental backups occur on the other six days. The primary copy of each backup remains at the CDT data center and is retained for 30 days. The replicated copy of each backup is located at the opposite campus within the Virtual Tape System.
Monitoring CDT proactively monitors the network and server infrastructure health with multi-layer security and monitoring systems designed specifically for the managed servers. Vendor Contract Administration CDT manages the vendor contracts for the zLinux platform and provides licenses for hosted servers.
Maintenance Schedule Preventative Maintenance Schedule. The rate schedule represents standard CDT services. The Customer creates an architectural diagram.

Would you share your thought process about what kinds of workloads are better suited to zLinux vs. Input from the group is welcome, of course. Not exactly how I want to spend my CPU budget. Some people turn off monitoring in total which is throwing the baby out with the bathwater so to speak. Then when you have issues, you have nothing in history to go against and you have to start from ground zero to find out what is normal. Putting something like a monitoring system on there does not make sense either, since that is a constant polling system.
That does work even when the rest of the systems are doing no work at all. Loading up a VMware cluster and then letting that spread the work around is far cheaper for us than IBMs solution set. Once you have more than a couple of special engines, then it starts to make sense to run more on the zVM and zLinux systems, but if you have just one or two engines, it is hard to make a case to do much on them other than science tests. Just my view point.
The results of our highly unscientific poll seem to back up your assertion that zLinux isn't widely used beyond, as you put it, science tests.
And yet, there seems to be a lot of interest in zLinux. Something to watch. But in my opinion, the entry costs to Linux on mainframes is much too high! If you're a purely distributed shop, and your server inventory is rapidly growing it may be cheaper to consider a cloud solution such as Amazon EC2, or the Google AppEngine - there's a lot more that goes into this decision such as data security requirements, and the portability of you applications.
What I wantet to state ist that Linux on system z ist too expensive to start with. If you go to your boss an tell him that you wnat to install linux on system z he says: " Why not, what does it cost me? All that stuff adds very fast to k. And that ist really too much for a system you joust want to play with or migrate some programs. In light of the good debate going on here, I thought I'd take a minute to update the results of our still highly unscientific poll.
Whether that's due to the expense involved or other factors is beyond the purview of this poll, but I'll leave that all of you to continue to debate here.
Once you have enough, then it is worthwile to use them for more than a simple test here and there. Hi Henrys,That's actually a great question to put to ndefreitas, who, so far, is the only voice here who seems to be using zLinux in production.
I am not sure about the scientific approach of your poll. Another poll mentioned by the Mainframe 2. He stared at me blankly for a minute then said "That might not be such a crazy idea".
That was in I believe they presented at Share years ago. If you only have and projected servers, okay, the mainframe is probably not worth it. Will large enterprises go to what they know, mainframes, or to something that has outages every months, Google, Amazon, Azure, Rackspace, etc.
I believe the question for will become, should an enterprise with a mainframe now get rid of ALL other servers? We are in for a Disney E-ride Hi KLCameron,You're not late at all--this is an ongoing discussion and one, as you note, that will likely get even more interesting in I, too, have seen the kinds of studies you mention that point to increasing interest in Linux on System z and I'm the first to point out the unscientific nature of our poll.
Cloud migration projects are happening in virtually every large enterprise throughout the world, and in many small and midsize companies as well. For most, cloud data migration is an ongoing journey, For organizations running IBM Z mainframe systems, several converging trends in recent years have made it more challenging than ever to achieve the needed organizational performance at the best Virtually everything in your business depends on IT running smoothly.
For most enterprises, service outages result in lost productivity, missed opportunities for revenue, and sometimes severe Christopher Tozzi May 10, Share on: LinkedIn Twitter Facebook. A very brief history of mainframe operating systems If you have worked in the mainframe world for decades, you know that mainframes are much older than Linux-based operating systems.
