Well it's Tuesday again, and you know what that means? IBM Announcements!
In my previous post, [How is Software Defined different than what we have now?], I explain how software can enable self-service automation through a "Control Plane" to request IT infrastructure resources, and a "Data Plane" to provision those resources.
IBM has chosen three particular Software Defined Environments. At one end, IBM is a platinum sponsor of OpenStack which supports x86 servers, POWER systems and z System mainframes. A problem with open source projects like this, however, is that they can be a bit like putting together IKEA furniture from pieces in a box: "Some assembly required."
At the other end, highly proprietary environments from VMware and Microsoft bring enterprise-ready out-of-the-box solutions. However, nobody wants to be limited to just x86-based solutions. IBM offers the best of both worlds, basing its IBM Cloud and SmartCloud software on OpenStack standards, but providing enterprise-ready solutions for x86, POWER Systems and z System mainframes. This includes IBM Cloud Manager with OpenStack, IBM Cloud Orchestrator, and IBM SmartCloud Cost Management software products.
(Analogy: If open source solutions were vanilla ice cream, and proprietary solutions were chocolate ice cream, then IBM Cloud and SmartCloud is vanilla ice cream with chocolate sauce on top! This is the same approach IBM used for WebSphere Application Server, based on Apache web server, and IBM BigInsights, based on Hadoop analytics.)
For some people, software defined can also refer to how the resources are deployed. Rather than using specialized hardware, solutions based on industry-standard hardware can be delivered either as pre-built appliances, services in the Cloud, or as software-only products.
Back in the 1990s, IBM came up with the [Seascape Storage Enterprise Architecture], deciding to focus the design of its storage systems to be based, where possible and practical, on industry-standard components.
Let's review a few products:
Combining the method the resources are controlled and managed with the way storage is deployed results in a quadrant. Let's take a look at this from a storage perspective:
IBM Spectrum Storage is a family of Category IV software offerings. Here are the products announced:
Last year, IDC recognized IBM as #1 in this new emerging software defined storage market. This announcement reinforces IBM's lead in this area. See the [Press Release] for details.

Well it's Tuesday again, and you know what that means? IBM Announcements!
Today, IBM announced an exciting new addition to the IBM System Storage™ product line, [IBM Spectrum Storage™], a family of software defined storage offerings.
To understand its significance, I need to explain a few things first. Software defined storage is part of a larger concept of software defined environment.
How is software defined environment different than what you have now? In every data center, you need to map business requirements of an application workload with an appropriate set of IT infrastructure, including server, network and storage resources.
The traditional approach involves an application owner or database administrator reviewing the business requirements documented for the application, calling the server, network and storage administrators, who match those requirements to appropriate IT hardware and notify the folks in facilities to rack and stack the gear accordingly.
In a software defined environment, Application Programming Interfaces (API), Service Level Agreements (SLA) and Orchestration workflows can automate the request for the appropriate resources. This is referred as the "Control Plane".
Responding to these requests, the software can provision the appropriate server, network and storage resources required. Server, network and storage virtualization, standard interfaces and deployment technologies exist to make this practical. This is referred to as the "Data Plane".
Any time new a way of doing things is introduced into the world, there could be some resistance. Let's tackle the three most frequently stated objections:
These concerns are addressed well enough in software defined environments, in general, and with IBM Spectrum Storage family of products, in particular.
(Nostalgia: I remember the days before self-service automation. At the bank, I had to stand in line at the bank until I could to talk to a human bank teller to get cash from my savings account. At the gas station, human gas attendants would come out and pump the gas for me, check my oil and wash my windshield. And at a restaurant, I felt like I waited an eternity from the time I ordered my meal to the time the human short-order cook had it ready and human wait staff delivered it to my table. These all seem silly today, doesn't it?)
Today in the USA, we honor [Martin Luther King, Jr.] This year marks the 50th anniversary of the largest political demonstration to date in American history. Over 250,000 people went to Washington DC to hear Dr. King give his now famous "I have a dream" speech.

Happy New Year everyone!
Well it's Tuesday again, and you know what that means? IBM Announcements!
(Update: I thought it was quite clever to announce the new z13 mainframe on January the 13th. A few [triskaidekaphobic] employees pointed out that certain [Greek and Spanish-speaking cultures] consider Tuesday the 13th to be an unlucky day. However, superstitious people should probably not work in IT, as it would be difficult for a worldwide company like IBM to avoid all the numbers that different cultures consider unlucky.)
IBM will have a live streaming event on Jan 14, Redefining Digital Business: The new generation of IBM z Systems], for those who want to hear the announcement in more detail. Here is what the invitation page has to offer:
You are cordially invited to join IBM on January 14 from 2:00pm to 4:30pm Eastern Standard Time (US) when IBM will share a whole new generation of IBM z Systems™ built to meet the needs of your digital business. Join us and learn how IBM z Systems are designed to:
At this live streaming event, you will hear from a remarkable group of business and technology leaders who will share success stories, best practices and the exciting technology innovations and capabilities of the new generation of IBM z Systems. Go to the Registration page] to participate.
But what does this really mean? Are you thinking BFD?
(Update: For those not familiar with IT acronyms, BFD refers to "Bigger, Faster, Denser" -- the trend in IT to announce new generations that are merely bigger, faster, and/or denser versions of the previous generations. Fortunately, the z13 takes up the same amount of data center floor space -- 2 floor tiles = 2 square meters = 20 square feet -- and weighs approximately the same as the z196 and zEC12, so raised floor struts do not have to be strengthened or reinforced to take in this new system.)
You may have noticed that we are now talking about "z System" instead of "System z". This change was made to line up with IBM's change to "POWER Systems" from "System p". Leadership felt that dropping the stodgy old zEnterprise and giving the mainframe a "hip" new name would attract new emerging digital workloads like Cloud, Analytics, Mobile and Social.
This is not the first time IBM has renamed products in a series. While the IBM mainframe just celebrated its 50th anniversary last year, the "13" refers to the 13th generation of CMOS-based mainframe technology introduced in 1994. Here is a quick table to show you the names that have evolved over the years:
(Note: This change also corresponds to a completely restructuring of IBM into business units, eliminating its former hardware and software groups. The design and development of all mainframe-related hardware, software and middleware will be consolidated under the IBM Systems business unit. I will wait for IBM's 4Q financial results announcement on or after January 20 before I cover this in any more detail.)
The z13 machine itself has some unique differences from previous generations. Instead of a "Multi-chip Module" (MCM) that contained multiple processor and storage controllers on a single slab, the z13 uses Single-Chip Modules (SCM) that are either a single 8-core processor, or a single system controller, allowing them to be field replaceable units (FRU).
Previous generations organized the processors in 1 to 4 vertical "books". The problem was that if you had a single book system, you bought a lot of hardware infrastructure designed to support a full four books. In the new design, processors are organized into horizontal Central Processor Complex (CPC) drawers, with additional hardware infrastructure provided per drawer. This makes the lower-end models more affordable. Each drawer has six processor SCMs and two system controller SCMs, providing 39 to 42 usable cores per drawer. Models ranges from 30 to 141 usable cores, with the option to upgrade from one model to another as your needs grow.
The z13 provides N-2 generation compatibility. This means you can have the z196, zEC12 and z13 all participate in the same Parallel Sysplex. You will also be able to upgrade your z196 or zEC12 to the new z13 system.
The new z13 can have up to 10TB of memory, and this can be assigned entirely to a single Logical Partition, or LPAR. The system can be subdivided up to 85 LPARs, versus 60 on the previous generation. Currently, z/OS v1 can only have up to 1TB per LPAR, and z/OS v2 can only go up to 4TB, so I suspect this 10TB is planning for future OS releases.
The new z13 now offers Simultaneous Multithreading [SMT]. Initially, this will double the number of threads for IFL engines (supporting Linux and z/VM), and zIIP engines supporting DB2, Java, XML and IPsec workloads. IBM is eliminating the zAAP engines, since zIIP engines can do all of that. The new [Preview z/OS v2.2] will take advantage of this SMT capability.
To assist with database, analytics and multimedia workloads, the z13 offers Single Instruction, Multiple Data [SIMD] capability. This allows a single instruction to perform the same update or action across many data fields.
For those clients with zBX models 2 and 3, allowing you to run POWER-based AIX and x86-based Microsoft Windows and Linux operating systems on your mainframe, they will be able to upgrade to [zBX model 4 for the z13 System]. Now that IBM has sold off its x86 server business to Lenovo, I suspect it will also phase out the zBX offerings as well.
To handle emerging workloads of Cloud, Mobile and other Web applications, IBM will offer a new stronger and faster Crypto Express5S cryptographic adapter. The z13 will enhance public key support for constrained digital environments using Elliptic Curve Cryptography (ECC) for users such as Chrome, Firefox, and Apple's iMessage. The z13 will also minimize reformatting of databases with new exploitation of VISA format preserving encryption (FPE) for credit card numbers.
The z13 also made some enhancements for Linux clients. The zAware analytics that analyzes internal traces and logs for z/OS has been extended to support Linux on System z. For those who want to use GDPS Business Continuity and Disaster Recovery services, but don't want to develop z/OS skills for the "K" system, there will now be a Virtual GDPS appliance that will run self-contained z/OS. Lastly, IBM has made a statement of direction that it will support open source Linux KVM as a Linux-only alternative to z/VM hypervisor. OpenStack will support both this new Linux KVM as well as z/VM 6.3 release.
The PCIe bus has been upgraded to Gen3 at 16Gbps, from Gen2 used in the zEC12. These can be used for Coupling Facility Links, which are faster than the legacy 6 Gbps InfiniBand, which are also supported for legacy migration. People with z196 and zEC12 can either carry forward their I/O drawers they have previously purchased, or move the PCiE Gen2 cards into the new Gen3 drawers.
The new z13 will also support 16Gb FICON, using the new FICON Express5S cards. Here is my segue into storage, as you are probably now wondering when I was going to get to the storage part of the announcement!
IBM is also announcing corresponding changes to the DS8870 firmware and accessories to go with the z13 System. This includes:
But don't just take my word for it, here are reviews of the new system from various journalists:
"They seem a computing odd couple: the mainframe, the old workhorse, and the smartphone, the cool-kid computer of today. But IBM has designed the latest version of the mainframe, which is being introduced on Wednesday, with the smartphone in mind. The new mainframe, the z13, has been engineered to cope with the huge volume of data and transactions generated by people using smartphones and tablets."
"One customer enthusiastic about such features is Citigroup Inc., a longtime IBM user that favors mainframes for both reliability and security. 'Security is in the DNA of the mainframe,' said Martin Kennedy, Citi's managing director for platforms and storage. Another factor shaping the bank's needs, Mr. Kennedy said, is the rising volume of transactions carried out using smartphones and other mobile devices. Mainframes are particularly good at combining data from a variety of systems and presenting them to a user's mobile app, he said."
"IBM is introducing a new mainframe in a bet that clients will need its souped-up speed and security to handle a surge in consumers using smartphones for everything from banking to checking health-care records. The z13 system can encrypt and analyze data in real time and process 30,000 transactions a second, International Business Machines Corp. (IBM) announced today. That means faster and safer transactions for consumers on mobile phones."
"With the unveiling of the z13, IBM has taken its MobileFirst Platform to deliver even better performance and security than before, as it incorporates the fastest microprocessor in the world, server processors that are twice as fast as existing products, 300 percent additional memory and 100 percent more bandwidth analytics speed. Last year, IBM formed a partnership with Apple to help bring Apple's iDevices to business customers to boost sales, with IBM providing cloud and mobile analytics support."
"'We're driving toward a world where more and more people are using mobile devices, or embedded devices, to interact with systems,' John Birtles, director of IBM z Systems, tells WIRED. 'We need to make sure that those devices are secure, that the transaction's secure, and that our clients get the level of analytics that gives them opportunities to improve their businesses.'"
IBM mainframes are used to process the majority of financial transactions around the world, is well positioned to handle Cloud, Analytics, Mobile and Social workloads. The IBM DS8000 series disk is the #1 market leader for disk storage on mainframe environments.
Well, it's the end of the year, so I thought a recap of year 2014 would be in order.
The year started out with some January announcements, including the IBM FlashSystem 840. IBM is proud to be ranked #1 in All-Flash Arrays, and the IBM acquisition of Texas Memory System has caused all of the other competitors to scramble their own wanna-be offerings. IBM also announced it was going to sell off its System x division to Lenovo.
In February, I wrapped up a project to build a Linux-based PC for a kindergarten class. IBM announced some exciting new things at Pulse 2014 conference, including IBM Bluemix Plat
In March, I completed a six-month film project ["A Tucson Executive Briefing Center: A Quick Visual Tour"]. I was writ
Also in March, I worked with the Netezza, Tivoli and Storwize V7000 team to work out [complete backup options for IBM clients who use PureData System for Analytics, powered by Netezza].
In April, I presented at the Systems Technical University in Istanbul, Turkey. I had been to Turkey before, but this was my first time to the city of Istanbul itself. The owner of my local [Savaya Coffee] is from Istanbul, and was able to introduce me to someone who was able to arrange for a full tour my first day! Meanwhile, on the other side of the pond, IBMers in New York were celebrating the 50th anniversary of the IBM mainframe, including a cameo appearance on the TV show "Mad Men".
In May, I was busy presenting at the IBM Edge conference in Las Vegas. IBM celebrated the sixth anniversary of IBM ProtecTIER data deduplication device, announced "Codename: Elastic Storage" and new features on the DS8870 disk system, and presented analyst findings that IBM Software Defined Storage was substantially less expensive than competitive offerings.
In June, I was recognized as one of the most influential bloggers in the IBM company, earning the prestigious [IBM Corporate Technology Social Business Imact Award for 2013].
In July, I took a nice summer vacation, [a road trip across the state of Tennessee]. IBM made a strategic partnership with Apple to offer mobile apps for the data center enterprise for the iOS operating system on iPhones and iPad tablets.
In August, I completed a summer partnership with University of Toronto and IBM Softlayer to build "Concept IBM Watson", a scaled down version of IBM Watson based on my infamous 2011 blog post [How to replicate Watson hardware and systems design for your own use in your basement]. Rather than using three physical servers, however, we had virtual x86 machines running on IBM Softlayer cloud. The system was only asked the simplest "How many...?" questions against a single text document, but proved to the University that teaching analytics by replicating IBM's historic achievement was effective and possible.
In September, I celebrated my eight year "Blogoversary". That's right, I have been blogging for the past eight years! With over 800 posts, and five published books, I countinue to be ranked #1 most-read blog on IBM developerWorks. IBM was ranked #1 for Software Defined Storage!
In October, I presented at the Systems Technical University in Dublin, Ireland. This was my first time in Ireland, and I found Dublin to be quite a beautiful city, with friendly people and delicious food.
The rest of October, and much of November and December, I spent on the road, visiting clients to help close deals! (Sorry folks... Due to SEC black-out rules, I am prohibited from telling you how well I did) Since I am not allowed to talk about on-going discussions that I have with clients, my blog has been noticeably silent during these months. I apologize for any stress or anxiety this might have caused any of my readers!
Despite too-much-candy, too-much-turkey and too-many-cookies that the year-end often brings, I managed to lose twenty pounds on a low-carb, gluten-free, Paleo diet and exercise.
2015 is shaping up to be a good year!
