LinuxONE is a Bargain

September 21, 2018

LinuxONE may be the best bargain you’ll ever find this season, and you don’t have to wait until Santa brings it down your chimney. Think instead about transformation and digital disruption.  Do you want to be in business in 3 years? That is the basic question that faces every organization that exists today, writes Kat Lind, Chief Systems Engineer, Solitaire Interglobal Ltd, author of the white paper Scaling the Digital Mountain.

Then there is the Robert Frances Group’s  Top 10 Reasons to Choose LinuxONE. DancingDinosaur won’t rehash all ten. Instead, let’s selectively pick a few, starting with the first one, Least Risk Solution, which pretty much encapsulates the LinuxONE story. It reduces business, compliance, financial, operations, and project risks. Its availability, disaster recovery, scalability and security features minimize the business and financial exposures. In addition to pervasive encryption it offers a range of security capabilities often overlooked or downplayed including; logical partition (LPAR) isolation, and secure containers.

Since it is a z dedicated to Linux, unlike the z13 or z14 z/OS machines that also run Linux but not as easily or efficiently,  As the Robert Frances Group noted: it also handles Java, Python; and other languages and tools like Hadoop, Docker, other containers, Chef, Puppet, KVM, multiple Linux distributions, open source, and more.  It also can be used in a traditional legacy environment or used as the platform of choice for cloud hosting. LinuxONE supports tools that enable DevOps similar to those on x86 servers.

And LinuxONE delivers world class performance. As the Robert Frances Group puts it: LinuxONE is capable of driving processor utilization to virtually 100% without a latency impact, performance instabilities, or performance penalties. In addition, LinuxONE uses the fastest commercially available processors, running at 5.2GHz, offloads I/O to separate processors enabling the main processors to concentrate on application workloads, and enables much more data in memory, up to 32TB.

In addition, you can run thousands of virtual machine instances on a single LinuxONE server. The cost benefit of this is astounding compared to managing the equivalent number of x86 servers. The added labor cost alone would break your budget.

In terms of security, LinuxONE is a no brainer. Adds Lind from Solitaire:  Failure in this area erodes an organization’s reputation faster than any other factor. The impact of breaches on customer confidence and follow-on sales has been tracked, and an analysis of that data shows that after a significant incursion, the average customer fall-off exceeds 41% accompanied by a long-running drop in revenues. Recovery involves a significant outlay of service, equipment, and personnel expenses to reestablish a trusted position, as much as 18.6x what it cost to get the customer initially. And Lind doesn’t even begin to mention the impact when the compliance regulators and lawyers start piling on. Anything but the most minor security breach will put you out of business faster than the three years Lind asked at the top of this piece.

But all the above is just talking in terms of conventional data center thinking. DancingDinosaur has put his children through college doing TCO studies around these issues. Lind now turns to something mainframe data centers are just beginning to think about; digital disruption. The strategy and challenges of successfully navigating the chaos of cyberspace translates into a need to have information on both business and security and how they interact.

Digital business and security go hand in hand, so any analysis has to include extensive correlation between the two. Using data from volumes of customer experience responses, IT operational details, business performance, and security, Solitaire examined the positioning of IBM LinuxONE in the digital business market. The results of that examination boil down into three: security, agility, and cost. These areas incorporate the primary objectives that organizations operating in cyberspace today regard as the most relevant. And guess who wins any comparative platform analysis, Lind concludes: LinuxONE.

IBM LinuxONE and Open Mainframe Project Expand the z System

August 20, 2015

Meet the new IBM z System; called LinuxONE Emperor (named after the Emperor Penguin.) It is a z13 running only Linux. Check out the full announcement here.

DancingDinosaur is 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. DancingDinosaur never believed it would refer to a mainframe as sexy (must be time to retire).

Along with LinuxONE Emperor IBM announced an entry dedicated Linux machine, the LinuxONE Rockhopper. (BTW; notice the new playfulness in IBM’s product naming.) Rockhopper appears to be very similar to what IBM used to call a Business Class z, although IBM has stepped away from that designation. The closest you may get to a z13 business class machine may be LinuxONE Rockhopper. Rockhopper, according to IBM, is designed for clients and emerging markets seeking the speed, security and availability of the mainframe but in a smaller package.

The biggest long term potential impact from the announcement may come out of the Open Mainframe Project. Like many of IBM’s community project initiatives, IBM is starting by seeding the open community with z code, in effect creating the beginning of an open z System machine.  IBM describes this as the largest single contribution of mainframe code from IBM to the open source community. A key part of the mainframe code contributions will be the z’s IT predictive analytics that constantly monitor for unusual system behavior and help prevent issues from turning into failures. In effect, IBM is handing over zAware to the open source community. It had already announced intentions to port zAware to Linux on z early this year so it might as well make it fully open. The code, notes IBM, can be used by developers to build similar sense-and-respond resiliency capabilities for other systems.

The Open Mainframe Project, being formed with the Linux Foundation, will involve a collaboration of nearly a dozen organizations across academia, government, and corporate sectors to advance development and adoption of Linux on the mainframe. It appears that most of the big mainframe ISVs have already signed on. DancingDinosaur, however, expressed concern that this approach brings the possibility of branching the underlying functionality between z and Linux versions. IBM insists that won’t happen since the innovations would be implemented at the software level, safely insulated from the hardware. And furthermore, should there emerge an innovation that makes sense for the z System, maybe some innovation around the zAware capabilities, the company is prepared to bring it back to the core z.

The newly announced pricing should also present an interesting opportunity for shops running Linux on z.  As IBM notes: new financing models for the LinuxONE portfolio provide flexibility in pricing and resources that allow enterprises to pay for what they use and scale up quickly when their business grows. Specifically, for IBM hardware and software, the company is offering a pay-per-use option in the form of a fixed monthly payment with costs scaling up or down based on usage. It also offers per-core pricing with software licenses for designated cores. In that case you can order what you need and decrease licenses or cancel on 30 days notice. Or, you can rent a LinuxONE machine monthly with no upfront payment.  At the end of the 36-month rental (can return the hardware after 1 year) you choose to return, buy, or replace. Having spent hours attending mainframe pricing sessions at numerous IBM conferences this seems refreshingly straightforward. IBM has not yet provided any prices to analysts so whether this actually is a bargain remains to be seen. But at least you have pricing option flexibility you never had before.

The introduction of support for both KVM and Ubuntu on the z platform opens intriguing possibilities.  Full disclosure: DancingDinosaur was an early Fedora adopter because he could get it to run on a memory-challenged antiquated laptop. With the LinuxONE announcement Ubuntu has been elevated to a fully z-supported Linux distribution. Together IBM and Canonical are bringing a distribution of Linux incorporating Ubuntu’s scale-out and cloud expertise on the IBM z Systems platform, further expanding the reach of both. Ubuntu combined with KVM should make either LinuxONE machine very attractive for OpenStack-based hybrid cloud computing that may involve thousands of VMs. Depending on how IBM ultimately prices things, this could turn into an unexpected bargain for Linux on z data centers that want to save money by consolidating x86 Linux servers, thereby reducing the data center footprint and cutting energy costs.  LinuxONE Emperor can handle 8000 virtual servers in a single system, tens of thousands of containers.

Finally, LinuxONE can run the sexiest app-dev tools using any of the hottest open technologies, specifically:

  • Distributions: Red Hat, SuSE and Ubuntu
  • Hypervisors: PR/SM, z/VM, and KVM
  • Languages: Python, Perl, Ruby, Rails, Erlang, Java, Node.js
  • Management: WAVE, IBM Cloud Manager, Urban Code Openstack, Docker, Chef, Puppet, VMware vRealize Automation
  • Database: Oracle, DB2LUW, MariaDB, MongoDB, PostgreSQL
  • Analytics: Hadoop, Big Insights, DB2BLU and Spark

And run the results however you want: single platform, multi-platform, on-prem and off-prem, or multiple mixed cloud environments with a common toolset. Could a combination of LinuxONE alongside a conventional z13 be the mainframe data center you really want going forward?
