On April 2nd IBM announced several key enhancements across the Storwize V5000 portfolio.
The models for the V5000 now include V5010E, 5030E and the V5100.
The V5010E includes two single socket Broadwell DE 2.2GHz, 2 core processor canisters. Each canister supports a maximum of 32GB of RAM.
The V5030E includes the Broadwell DE 1.9GHz, 6 core processor in its two canisters. Each canister supports a maximum of 32GB of RAM.
The V5100 boasts a single Skylake 1.7Ghz processor with 8 cores in each canisters. RAM is increased to a total of 576GB for the entire controller, or 288GB maximum per canister.
From a scale out perspective the V5010E model supports a single controller configuration, while the V5030E and V5100 both support up to two controller clusters. This provides for a maximum of 392 drives in the V5010E and a massive 1520 drives in either the V5030E or V5100 dual controller clusters.
While the new lineup for the V5000 is impressive; regarding the quantity of drives, and the storage available per model will blow your mind.
The V5000E & V5100 versions support the following drive types.
Along with the compute & cache layer enhancements across the V5000 platform, the V5100 receieved a large boost in its storage support. IBM has delivered a solid Flash / Hybrid storage controller player to the markey. In the V5100 model we now support both the Flash Core Modules (FCM) and or NVMe Industry Standard SSD drives. In addition in the expansion drawers you can add even more SAS SSD, 10K and NL-SAS capacity.
The combination of Flash Core Modules and NVMe Industry Standard drives makes the V5100 the perfect low to medium class storage controller.
Both the V5010/30E and the V5100 models offer the following on board interface ports per canister:
The Storwize V5000E models support 1 additional interface card, or 1 SAS host attachment adapter per canister. The optional interface cards available are:
The Storwize V5100 model also supports 1 host interface card, and also optionally up to two SAS Storage Expansion adapters. The adapter interface cards available for the V5100 are:
Regarding the software features for the V5000E and V5100 models, all of the models discussed still include the following features as shown. Specifics on the actual software features is documented below:
Reviewing this information has been eye awaking and though valuable I have only touched on pieces of this latest update for IBM storage.
For those seeking an even deeper depth of knowledge I refer you to my learned colleague Barry Whites blog,
Visit Barry's blog [Storage Virtualization] for more details.
Leaving a discussion like this and not providing a review across the Storwize Block Family would not be welcomed by you my readers.
Here is a table reflecting the features by model for your quick reference.

It's good to see IBM TotalStorage Productivity Center evolve and expand. I was the lead architect for this product a few years ago, and my has it come a long way from its early beginnings.
Today, Gartner, Inc. has IBM Positioned in Leader Quadrant for Storage Resource Management and SAN Management Software.
The Magic Quadrant is copyrighted concept by Gartner, representing a two-by-two grid that ranks various offerings from different vendors. Ideally, vendors want their products in the upper right "Leaders" quadrant. Yahoo Finance reports:
According to Gartner, Inc., "Leaders have the highest combined measures of an ability to execute and a completeness of vision. They have the most comprehensive and scalable products. They have a proven track record of financial performance and an established market presence. In terms of vision, they are perceived as thought leaders, having well-articulated plans for ease of use, how to address scalability and product breadth. For vendors to have long-term success, they must plan to address the expanded market requirements for change management and root-cause and performance analysis. Leaders must not only deliver to the current market requirements, which continue to change, but they also need to anticipate and deliver on future requirements. A cornerstone for leaders is the ability to articulate how these requirements will be addressed as part of their vision for resource management. As a group, leaders can be considered a part of most new purchase proposals, and they have high success rates in winning new business."IBM TotalStorage Productivity Center is a strategic part of IBM Service Management, and a foundational component of the IBM Systems Director family. IBM is making a concerted effort across servers, networks, software and storage to help manage the IT infrastructure in a coordinated way.
I have seen other quadrants used to help explain different market segments, such as the one used in this 40-minute video Guy Kawasaki’s Art of the Start speech at TiECon 2006.
To the current architects and developers of Productivity Center, well done!
Every year, March 31 marks "World Backup Day". Sadly, many people forget the importance of backing up their critical information. This is not just true for businesses, non-profit organizations and government agencies, but also for all of your personal information that you keep on computer devices.
My friends over at Cloudwards had developed an awesome infographic related to World Backup Day. Here it is.
(FTC Disclosure: I work for IBM, which has no business relationship with Cloudwards. Cloudwards does not itself provide backup services, but rather reviews services provided by others. This post should not be considered an endorsement of Cloudwards or their reviews.)
I hope you find this information helpful and informative!
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University. On Wednesday evening, we had a poster session.
(I have so many photos that I will split this post up into topics. This post will focus on posters related to IBM Power systems. See my other posts for storage and IBM Z.)
Ding! IBM i Systems Management redefined with SQL
A poster presentation should trigger question-and-answer sessions, and the exchange of ideas and information regarding your topic.
Scott Forstie, IBM Db2 for i Business Architect, coined the phrase "Scott's Query Language", focused on Data Services for Db2 database on IBM i operating system. His design took several charts, printed in landscape mode, and organized in 3 columns of four charts each. His "title" page was printed twice, and placed on the left and right sides.
Scott explained GROUP_PTF_CURRENCY, LICE
IBM Spectrum Scale with Hortonworks Data Platform
Chris Maestas, IBM Global Senior Solutions Architect, IBM and Par Hettinga, IBM Global SDI Enablement Leader, created this poster.
Hortonworks is a leading innovator in the industry, creating, distributing and supporting enterprise-ready open data platforms and modern data applications. They focus on driving innovation in open source communities such as Apache Hadoop, NiFi, and Spark. Their product, Hortonworks Data Platform (HDP), runs on both x86 and Power systems.
The poster design was clean, with basically three enlarged presentation slides. On the top, it explains that Hortonworks now supports IBM Spectrum Scale for storage of files and objects to be analyzed by Hadoop. On the bottom left, it shows how Spectrum Scale eliminates the ingest-and-discard approach used by other HDFS-based systems. On the bottom right, an architecture diagram to build your own "data lake".
Optimizing Power Performance with Affinity Groups – Real World 40Gbit LPM Results / Lessons Learnt
This poster employed a unique 1-6-6 design. Top slide was for title and author: Stephen Diwell, Senior Power Systems Engineer, DXC Technologies
In the middle, the poster had six traditional text-only presentation slides, arranged in two rows of three. LPAR Affinity Groups provides you the ability to give the Hypervisor a hint that you would like this group of LPARs to be located on processor Chips that are closer to each other. Use Affinity Groups to help the Hypervisor place LPARs nearer to the VIO Servers. LPARs that share common resources, like the Fibre Channel and Ethernet adapters within a VIO servers will obtain better performance and adapter throughput the closer they are. The lighting on some of these posters was really poor, and perhaps too dark to read small fonts like this.
At the bottom were performance bar chart results, in three rows of two. I like the use of color for the graphs. For a network job with 8 threads, Stephen achieved a 54% increase in network bandwidth for LPARs communicating on the same Chip to those communicating between Nodes in the E800 frame.
Sundata Power Server Cloud offering
Leave it to the marketing department of a local cloud service provider to turn their poster into an advertising billboard! This one was presented by Kon Kakanis, Managing Director, Sundata Pty Ltd
The Sundata poster encouraged people to move their AIX, IBM i and Linux on POWER workloads to their "PowerCloud" platform. They summarized their advantages into four bullet points:
Founded in 1986, Sundata is an Australia-based organization to help their clients transform into the Cloud, select and deploy IT hardware and keep the lights on with ongoing support and managed services. They have over 100 corporations, government departments and schools enjoying a close and ongoing relationship.
The large fonts, simple design, and the cute cat-in-a-cape logo in the lower right corner captured peoples attention!
In between reading posters and talking to everyone, it was good to take a quick look out the floor-to-ceiling windows. At 297 meters, Eureka Tower has some amazing views. Here is one of the Yarra river and Central Business District.

Next week, I will return to Istanbul, Turkey to present at the [IBM Systems Technical Symposium], June 1-3 at the Hilton Bomonti hotel.
(Frequent readers of my blog may remember that I had been to Istanbul for a similar conference last year. I arrived a day earlier to do some sightseeing, which I documented in my April 2014 blog post [Arrived Safely to Istanbul].)
Like IBM Edge conference in Las Vegas earlier this month, this conference will not just be for Storage, but also include z Systems and POWER Systems content. Here are the sessions I will be presenting:
If you are attending next week in Istanbul, I will see you there!
Last week, fellow IBM blogger Barry Whyte Barry pointed out that my recent post on [Cognitive University for Watson Systems SmartSeller] was my 1,000th blog post. After 10 years of blogging, I have reached the 1,000 mark!
(As IBM is focused on its transformation from a "Systems, Software and Services" company to a "Cognitive Solutions and Cloud Platform" company, it seems appropriate to highlight my 1,000 blog post on the concept of cognitive solutions.)
A lot of people ask me to explain what exactly does IBM mean by "cognitive", which is a fair question. Let's start with the [Dictionary definition]:
What exactly does IBM mean by Cognitive? IBM has taken this definition, and focused on four key strategic areas:
IBM is exploring the use of Cognitive Solutions in a variety of different industries, from Healthcare to Retail, Financial Services to Manufacturing, and more.

But wait, there's more!
I realize this conference is five months away, however one of my pet peeves is learning about a conference, especially a first-of-its-kind conference like this one, at the last minute, and not having time to plan accordingly. Travel budgets are tight for lots of people, so as an added incentive there is a $600 US dollar discount per person if you register before February 1, 2008. So don't wait! Sign up today!Read More]
Later this month, I will be attending the [InterConnect Conference] in Las Vegas, Feb 21-25, 2016. This is IBM's premier Cloud & Mobile conference for the year.
Fellow blogger Stuart Thomson has a great post title [Storage & infrastructure @ InterConnect 2016: The choices are all yours] which provides some interesting statistics:
Wow! That can seem overwhelming. While the conference spans multiple hotels on the strip, I personally will be focusing my time at the [Mandalay Bay resort]. My session will be held at the Solutions Expo on Wednesday 1:45pm. Here are the details:
To help attendees plan your week, InterConnect has a [Session Preview Tool]. I have already found over 40 sessions related to Storage that I am interested in attending!
Need to register? Here is the [Registration Link].
I will be there all week, so if you see me, stop and say "Hello!"
This week, I am in Dublin, Ireland for the [IBM System x, IBM PureSystems and System Storage Technical University] conference.
Here are the sessions that I will be speaking at:

Over 4,000 issues of your favorite magazine now sit, ready for you to search and savor, on an 80GB incredibly lightweight and travel-friendly drive. This high-performance, brushed-aluminum Hard Drive measures only 3x5-inch and can easily fit inside a purse or briefcase so show it off to your tech-savvy friends and co-workers. Plus, there is plenty of extra room on the drive for future updates. Simply install The Complete New Yorker Program (installation CD provided), then connect the drive to a USB port on your Computer and have instant access to every article, poem, short story, and cartoon including every advertisement that has appeared in the magazine since 1925.
The 750MB of disk space required on your system probably contains the indexing/metadata search system to find articles by subject, title or author. Linux is not listed, and if 750MB of disk space are required to run the program, then perhaps this system won't work with Linux at all.
The system claims that there is extra room on the disk to ingest future issues of the magazine. I wonder why they didn't put the indexing/metadata search software on the drive itself, so that it would be self-contained, rather than having a separate installation CD.
I think this is a sign of our times. The New Yorker magazine has taken the archives that they keep anyways, and made them available in bulk, in a handy disk drive delivery system. I know several people who keep boxes and boxes of back issues of all kinds of magazines, and this certainly is an improvement.

Well, it's Tuesday again, and you know what that means? IBM Announcements!
(OK, yes, today is Friday, but I was busy getting married on Tuesday, so IBM pushed the announcements out one day to Wednesday, and technically I am writing this blog post during my honeymoon vacation, so the IBM marketing team and my new wife both cut me some slack. Work/Life balance is all about compromises, right?)
By now, there are multitude news articles on these announcements, so I recommend you go look for them.

I am back from China, and now glad to be back in the old USA. Last week, someone asked me what would it take to add a specific feature to the IBM System Storage DS8300. The what-would-it-take question is well-known among development circles informally as a "sizing" effort, or more formally as "Development Expense" estimate.
For software engineering projects, the process was simply that an architect would estimate the number of "Lines of Code" (LOC) typically represented in thousands of lines of code (KLOC). This single number would convert to another single number, "person-months", which would then translate to another single number "dollars". Once you had KLOC, the rest followed directly from a formula, average or rule-of-thumb.
More amazing is that this single number could then determine a variety of other numbers, the number of total months for the schedule, the number of developers, testers, publication writers and quality assurance team members needed, and so on. Again, these were developed using a formula, developed and based on past experience of similar projects.
Earlier in my career, I was the lead architect for DFSMS for the z/OS operating system, and later for IBM TotalStorage Productivity Center, performing these sizing efforts. A famous IBM architect, Frederick P. Brooks, wrote a now-classic book that was requiredreading when I started at IBM, which just was re-released as Mythical Man-Month: Essays in Software Engineering, 20th Anniversary Edition. In addition to sound advice, he alsooffered a formula or two that helps with these estimating tasks.
Hardware design introduces a different set of challenges. When I was getting my Masters Degree in Electrical Engineering, it took myself and four other grad students a full semester just to design a six-layer, 900 transistor silicon chip, which could only perform a single function, multiply two numbers together.At IBM, another book that I was given to read was Soul of a New Machine, documenting six hardware engineers, and six software engineers, working long hours on a tight schedule to produce a new computer for Data General.
So why do I bring this up now? IBM architects William Goddard and John Lynott are being inducted posthumously this year into the prestigious National Inventors Hall of Fame for their disk system innovation.
Under the leadership of Reynold Johnson, the team developed an air-bearing head to “float” above the disk without crashing into the disk. Imagine a fighter airplane flying full speed across the country-side at 50 feet off the ground. If you every heard the term "my disk crashed", it was originally referring to the read/write head touching the disk surface, causing terrible damage.
A uniformly flat disk surface was created by spinning the coating onto the rapidly rotating disk, leaving many wearing lab coats covered with disk liquid at waist level. Developing disk-to-disk and track-to-track access mechanisms proved more challenging, and nearly halted the project. The team, however, was adamant that this problem could be solved, and customers were increasingly asking for random access technology. The result was the "350 Disk Storage Unit" designed for the "305 RAMAC computer", which I have talked about a lot last year as part of our "50 years of disk systems innovation" celebration.
Neither Goddard nor Lynott had computing experience prior to joining IBM. Goddard was a former science teacher who briefly worked in aerospace. Lynott had been a mechanic in the Navy and later a mechanical engineer. They didn't have a nice formula based on past experience, they didn't have the benefit of Fred Brooks' advice, or the rules-of-thumb or averages now used to estimate the size of projects. They had to break new ground.
Now that's innovation!

Wrapping up my week teaching Top Gun class in Sydney, Australia, I could not resist taking a photo of the cityscape.
Sydney is a beautiful city, and the view from the 13th floor of the IBM Centre at St. Leonards in North Sydney is always worth a picture!
Vic, Scott and I all have engineering backgrounds, so it is easy for us to drop down into the technical weeds in discussing each product and solution. However, the student feedback from both Auckland and Sydney was that some of our material was just too technical.
"Shoe salesman should know how to tie a pair of shoe laces, but do not need to know [how the little aglets at the tip of each lace are made] just to sell a pair of shoes!"
Rather than presenting my standard 137-slide "Dea
Last week, we celebrated Joe's birthday in Auckland. This week, it was Vic's turn, so we went to the Garfish restaurant at Manly beach. Here we are with bacon-enhanced oysters.
The four-day class finished Thursday afternoon, and I went out with some of the students to celebrate their graduation. I started with beers at the Cabana, then wine at [the Ivy Room], and finally dinner at Uccello on the rooftop [Pool Club]. Dinner was awesome: pork sausage-stuffed olives to start, roasted chicken with polenta, and finally a capuccino to finish the meal.
I would have never found these places on my own, and the students provided me some interesting feedback about the class and how to improve it.
I am in Toronto, Canada. It is a lot cold and rainy here, worse than last week in Seoul, Korea.This looks like a slow news week, so slow that the only news here in Canada is the possibility of anew 5-dollar coin. I thought I would make this week's theme about enterprise applications.
IBM doesn't make these applications anymore, we have decided to focus on our core strength, to be the best IT platform to run other people's applications. This means being the best IT systems, software and services company. However, many of the companies that make enterprise applications are both cooperate and compete against parts of IBM, what we call "coopetition".
Let's take a look at some acronyms in this space:
This week I will cover applications that address these, and how they relate to storage.Read More]
Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape, with four specific examples. There was a lot of reaction and reflection fromboth sides.

It's official! IBM System Storage TS1120 tape drive takes home the gold award, the product of the year, announced by Storage magazine.
I spent 18 hours traveling from Australia to China yesterday, and we were partially delayed due to weather, but felt that it was necessary to discuss the innovative use of encryption on this drive.
While most consider the TS1120 an "Enterprise-class" tape technology for the mainframe, it is also attachable to the smallest distributed systems running Windows, Linux, or various flavors of UNIX. Rather than limit users with an Encryption Key Manager that only ran on z/OS, IBM instead chose to implement it in Java, that can be run on anything from z/OS to Linux, Unix and Windows platforms, giving clients choice and flexibility in their deployment.
The design is quite clever and elegant. In the encryption world, there are two ways to encrypt.
So, let's say that Green, Inc. wants to send a tape to Blue, Co. Blue has already provided its public "encryption" key to Green, so Green does the following:
If the super-secret private key is ever compromised, all you have to do is mount the tape, unlock the red key with the old private key, and re-lock the red key with a new public key. Since the red key doesn't change, the rest of the data can be left in tact. The whole process takes less than 5 minutes, compared to Sun Microsystems method, which could take 1-2 hours per cartridge, having to decrypt and re-encrypt the entire data stream.Read More]
I will wrap up this week's theme on travel, conferences and Japan discussingGroundhog day, celebratedtoday (Feb. 2) in the US.
I thought of this because there was a 2003 movie called"Lost in Translation", the title of yesterday's post. This movie is about an American actor, played by Bill Murray, coming to Tokyoto film a whisky commercial. I first saw it with my sister and father, and we musthave been the only three who have actually been to Japan, as we were laughing hysterically,while the rest of the audience was utterly confused. If you have never been to Japan, see the movie before you go, then see it again after you get back home.
Ten years earlier, Bill Murray also played the lead role in another movie called"Groundhog day".In the movie, Bill Murray's character is TV newsman "Phil Connors" who travels to a small townwhere they bring out a small groundhog. If the groundhog can see his shadow, it predictsat least six more weeks of winter. If it does not, winter will end sooner. The nextday, Phil wakes up to realize that he is re-living the same day, over and over, like a modern-day Sisyphus or Promethius. Howhe handles himself in this situation, is what makes the movie so memorable.
When I explain what I do for IBM, to people I meet at home and abroad, I get asked the same set of questions.
The amount of information stored and available today is astounding. Consider the following:
...a weekday edition of The New York Times contains more information than the average person was likely to come across in a lifetime in seventeenth-century England.
Shawn Callahan mentions this in his great presentation on how work really gets done.
Mark Nelson covers this in more detail inWe Have the Information You Want, But Getting It Will Cost You: Being Held Hostage by Information Overload.
To help address this challenge of organizing finding the right information at the right time, Web 2.0 technologies have emerged. You can read the 16-page paper What Is Web 2.0? -- Design Patterns and Business Models for the Next Generation by O'Reilly.
Or better yet, watch the quick 4-minute video Web 2.0 ... The Machine is Us/Ing Us.Read More]
I didn't really have a theme this week, still recovering from jet-lag from my travels through Japan, Australia, China.
Gary Diskman has an amusing blog entry about a Funny disaster recovery job posting. It is not clear if he is being completely tongue-in-cheek, or a bit cynical. However, it rings true that you get what you measure, and some managers look for easy metrics, even if there are unintended consequences.
Western medicine works this way. Rather than paying your doctor to keep you healthy, you pay him per visit, to get refills on prescriptions, check-ups on medical conditions, surgeries and so on. While Eastern medicine is focused on keeping people healthy, Western medicine profits more from resolving "situations".
I have seen similar situations on the "health" of the data center. In one case, the admins were measured on how quickly they bring back up their web-servers after a crash. They had this process down to a science, because they were measured on how quickly they resolved the situation. I suggested switching from Windows to Linux, a much more reliable operating system for web-serving, and showed examples of web-servers running Linux that have been up for 1000 days or more. Management changed the metrics to "average up-time in days" and magically the re-boots all but disappeared, thanks to Linux, but also thanks in part to shifting the incentive structure. Perhaps some of those earlier situations were "artificially created"?
Back in the 1980s, I was working on a small software project that was about 5000 lines of code. In those days, testers were measured by the number of "successful" testcases that ran without incident. Testcases that uncovered an error were labeled as "failures" to be re-run after the developers fixed the code. When I declared my code ready for test, the test team ran 110 testcases, all successfully, and they were all rewarded for meeting their schedule. I, on the other hand, did not accept these results, met with them and told them I would give them $100 each if they could find a bug in my code in the next week. Nobody writes 5000 lines of code without some error along the way, not even me. (As one author put it, more people have left earth's gravity to orbit the planet than have written perfect code that did not require subsequent review or testing. It's so true. Good software is difficult to write.)
The test team accepted the challenge, and found 6 problems, more than I expected, but at least I felt more confident of the code quality after fixing these. As I suspected, the unintended consequence of counting "successful" testcases was that testers would write the most simple, basic, leas So, my advice is to determine metrics that have the intended consequences you want, while avoiding any negative unintented consequences that might undermine your eventual success. People will quickly figure out how to maximize the results, and if you can align their goals to company goals, then everybody benefits. Well, I'll be blogging from Mexico next week (yes, it is a business trip!). Enjoy the weekend.
