Well, it's Tuesday again, and you know what that means? IBM Announcements!
This week, IBM announces the second generation of Storwize V5000 flash and disk storage systems. There are the V5000F All-flash configurations, as well as the V5000 that can support a variety of flash and spinning disk drives.
There are three models:

Can you believe it has been a year already since IBM announced VersaStack?
In my May 2012 blog post, [EMC Strikes Back], I poked fun at the fact that Cisco had two
Cisco originally partnered with EMC to create a converged system called Vblock which combined Cisco UCS servers and switches with EMC storage. The partnership between VMware, Cisco and EMC was dubbed Virtual Computing Environment (VCE).
However, Cisco then partnered with NetApp to create Flexpod, a converged system that combined Cisco UCS servers and switches with NetApp storage. Many of my clients felt that Flexpod was an improvement over Vblock.
A lot has happened since then. In 2014, [drastically reduced its investment in VCE]. Last year, Dell then spent $67 Billion dollars to effectively take EMC out of the storage business. While this was a huge birthday present for IBM, not everyone is happy to see EMC fade away. Whitney Garcia has a great article titled [Crying at the Dell-EMC wedding: Why VCE customers should consider alternatives].
Before VersaStack, IBM had its own converged system, PureSystems, which combined IBM POWER and x86 servers with IBM storage. The x86 server portion of this business was sold off to Lenovo, but IBM continues to sell POWER-only and blended x86-and-POWER PureFlex systems, as well as PureApplication and PureData systems.
The [VersaStack] collaboration between IBM and Cisco offers an alternative to Vblock and Flexpod converged systems. Cisco is a leader in x86 blades and networking switches, and IBM is #1 in Flash and Software Defined Storage, including Storage Virtualization. VersaStack gives you the best of both worlds!
The VersaStack has Cisco Validated Designs for use with IBM's Spectrum Virtualize products:
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!"
As you can imagine, I get a lot of email from around the world. This one, from a loyal reader from overseas, was particularly interesting. Normally, I would direct them to read the fantastic manual [RTFM], but decided instead to go ahead and tackle it here in my blog.
I will tackle this in three steps.
First, let's attach "Server 1" and the FlashSystem 900 to the SAN fabric. IBM Spectrum Virtualize can handle one, two or even four separate fabrics. Let's assume you have a dual-port Host Bus Adapter (HBA) in server 1, and two redundant fabrics. We will connect each server port to each FCP switch. Likewise, we will connect each FCP switch to the FlashSystem 900, carve up "Volume 1", and create SAN "Zone A1" and "Zone A2", which identify "Server 1" as the initiator, and "FlashSystem 900" as the target. This is all basic stuff.
For those who want to follow along, I suggest you review the full implementation guidance in the IBM Redbook [Implementing the IBM Storwize V7000 Gen2]. Here is an excerpt:
"All Storwize V7000 Gen2 nodes in the Storwize V7000 Gen2 clustered system are connected to the same SANs, and they present volumes to the hosts. These volumes are created from storage pools that are composed of mDisks presented by the disk subsystems. The fabric must have three distinct zones:
Second, we connect the Storwize V7000 Gen2 to the FCP switches. You don't need to connect all of the ports, but I recommend that you have each controller node to each FCP switch, requiring four cables. Add more connections for added performance bandwidth.
Carve up "Volume 2" and this will be referred to as a "managed disk", mDisk for short, and create a "storage pool" which were formerly known as a "managed disk group" which is why you often see MDG in the naming conventions and examples. Storage pools can have one or more managed disks, and you can add more dynamically as needed.
The "storage zone" indicates the Storwize V7000 Gen2 as the initiator, and the FlashSystem 900 as target. If you want to increase the performance bandwidth, consider more cables between the FCP switches and the FlashSystem 900. We create "Zone B1" and "Zone B2". I recommend a separate "storage zones" for each additional storage system that you choose to attach to the Storwize V7000 Gen2.
The "cluster zone" that connects all of the Storwize V7000 Gen2 node ports together for node-to-node (intra-cluster) communication. Storwize V7000 Gen2 ports can serve as both initiators and targets dynamically. For example, when you write to one node, the node then copies the cache block over to the second node so there are two copies stored safely on separate nodes. Since we have two fabrics, we create "Zone C1" and "Zone C2".
Third, we connect "Server 2" to FCP switches, same as we did with "Server 1". We create "Volume 3" which is a "virtual disk, or vDisk for short, from the storage pool containing Volume 2. The "host zone"indicates Server 2 as the initiator, and Storwize V7000 Gen2 as the target. We create "Zone D1" and "Zone D2". I recommend putting each additional server in its own set of host zones.
In theory, you could have a server connected to both Volume 1 and Volume 3. For example, a Windows server would have a "C:" drive connected directly to FlashSystem 900 for high-speed performance, and have a "D:" drive on Storwize V7000 Gen2 to contain data. The Storwize V7000 Gen2 introduces 60 to 100 microseconds of added latency, but provides added value such as FlashCopy, Thin Provisioning, and Real-time compression.
Of course, there are unique situations that might require special configurations, depending on the servers, operating systems, host bus adapters, FCP switches, and storage systems involved.
In the 2004 comedy ["A Day Without a Mexican"], the director envisions how disruptive life would be in California if all the Mexicans suddenly disappeared. The point is that sometimes you take things in the background for granted.
I was reminded of this when I saw Mark Underwood's blog post [Mainframe: Still Not Crazy After All These Years]. The article reminds us how critical IBM z Systems mainframes (and related storage like the IBM DS8880 disk systems) are in our lives. Here's an excerpt:
What would a comparable film depicting "A Day without a Mainframe" be like? I would imagine it somewhere between a disaster movie like  and an end-of-the-world zombie horror movie like [28 Days Later]. I would gladly take a million dollars to write the screenplay!
(FCC Disclosure: I work for IBM and am a filmmaker as well. Earlier in my career, I was chief architect of IBM's Data Facility Storage Management Subsystem (DFSMS) which manages around 80 percent of the world's corporate data. This blog post can be considered a "paid celebrity endorsement" for IBM's z13 System mainframes and DS8880 Disk Systems. I have personal experience with both and highly recommend them. I am neither a Mexican nor resident of California, but work regularly with both in my job responsibilities. Like Warren Buffett, I also own stock in both IBM and Berkshire Hathaway companies. I had no involvement in the making of any of the major motion pictures mentioned in this blog post, have no financial interest in their distribution, and have not been provided any compensation for mentioning them in this blog post. They are all great movies worth watching!)

Happy New Year!
Well, it's Tuesday again, and you know what that means? IBM Announcements!
This week, the new model 314 is [now available in all countries] that IBM does business in.
(Actually, the [XIV Model 314] was announced on Nov 10, 2015 last year, but announcements made in November and December are often overlooked between distractions like holidays and year-end processing. Today's announcement was to eliminate the "not available in some countries" restriction. The last time I mentioned on this blog that a product was not available in some countries, I had tons of questions of "why". Hopefully, waiting until a product is available in all countries eliminates that concern.)
What does the XIV model 314 offer? IBM doubled the processors, up to 180 cores, and doubled the DRAM cache, up to 1440 GB. Both of these changes were done to improve the Real-time compression capability.
To reduce test effort cycle time, IBM simplified the configuration options:
Through a combination of thin provisioning and compression, you can define up to 2 PB of soft capacity per rack.
The firmware v11.6.1 reduces the minimum volume size for compression from 103GB to 51GB. Firmware perpetually licensed for Spectrum Accelerate can be used with the XIV Model 314.
Happy Holidays everyone!
Every December, the "birthday boys" -- Bill, Kris and I -- celebrate our birthdays. For me, it is the big five-0h. According to a recent Harris poll, it is [America's favorite age!] For some people, [fifty is the new thirty]!
From left to right: Melinda Jensen, Bill Terry, Lee Olguin, Kris Keller, Tony Pearson, and Kristy Knight.
The storage, cloud and analytics team celebrated with cake and party hats. None of us "birthday boys" eat chocolate, so this year we chose a new flavor: Strawberry Cream! It was delicious.
It was a good time to reflect on our success and accomplishments. In 2015, I helped close over $270 million USD in revenues for IBM, meaning that I helped close over a million [per day on the job].
The IT industry went through a lot of changes also. Hewlett-Packard [split into two smaller pieces]. Dell started [EMC's fade to non-existence]. Cisco and IBM joined forces to create VersaStack, a converged system that combines the most popular x86 servers with the industry's best storage. Analysts recognized IBM's leadershp in today's [Cognitive Era].
Looking forward to an exciting 2016!
My friends over at Appcessories sent me an awesome infographic on the Internet of Things. If you happen to receive any gifts this holiday related to any of these categories, mention them in the comments below!
Enjoy your time off with friends and family!
Last Friday, I helped students learn about Science, Technology, Engineering and Math (STEM). This was the annual [2015 Arizona STEM Adventure] event in Tucson, Arizona. This year, Pima Community College Northwest Campus provided the venue.
The event hosted more than 900 students, ranging from fourth to eighth graders. Buses collected them from 31 schools across seven cities and towns in the Tucson area. Home-schooled, private-schooled and charter-schooled children participated as well.
I was just one of 130 volunteers. IBM, [Raytheon], [Pima Community College], [Agents of STEM], [SARSEF, [StemAZing], [Office of Pima County School Superintendent], [UA Stem Learning Center], and other individuals volunteered their time to make this happen.
As I arrived, students lined up to ride this "hover chair". A lawn-blower motor floated a chair attached to a platform. A blue tarp represented water. Volunteers would pull the hover chair across the tarp, giving the kids a fun ride. I wanted to ride it myself, but it was not engineered for my body weight!
Students chose among the most interesting of 50 exhibits. IBM led two of these exhibits.
First, we had the [Bike Wheel Gyroscope]. The students would stand on a rotating swivel platform, holding a spinning bicycle wheel. When the student tipped the wheel left or right, the students body would rotate on the platform!
Second, we had Share with Storyboarding. This is the one I volunteered for. IMHO, the best part of STEM is the Arts and Design aspect needed to make products usable. Perhaps we should rename STEM to STEAM to add "A" for Arts and Design.
We held six 30-minute sessions with each group of students. Our team lead, Brenton Elmore, IBM Design Principal, explained what storyboards are, and then gave the students five topics to choose from:
Children paired up in two-person teams based on their topic interest. Why teams? Many creative collaborations involve the strengths of different teammates. For example, an author and an illustrator work together to create a comics or children's book. Broadway musicals often have a writer and composer.
Each team spent 10 minutes to draw a six-panel storyboard on [Post-it notes]. These would be stuck to a single sheet of paper. The team then would write underneath each panel the narrative of what was occurring.
Brenton taped five or six of these to the wall to share with the rest of the class. Each team would then explain to the other students what they drew, and the narrative to go with it.
When there were an odd number of students, one of us volunteers paired up with a student. Shown here is Marilynn Franco, IBM Manager, helping young Bailey in explaining their storyboard. I helped young Lili with her storyboard about a new mobile phone app idea she had.
Storyboards are an essential part of IBM's [Design Thinking]. We use them in a variety of ways, from designing business strategies and product enhancements, to creating videos about the [IBM Tucson Executive Briefing Center]!
When I make presentations to clients at briefings or conferences, I use 36 slides per hour. Each PowerPoint slide serves like a storyboard panel, and I provide the narrative on each one.
Special thanks go to Kathy Carlisle, IBM Tucson Site Operations Manager, and Mike Hernandez, IBM IBM Corporate Citizenship and Corporate Affairs Manager, for setting this up!

Well it's Tuesday again, and you know what that means? IBM Announcements!
(FCC Disclosure: This official launch also includes October 6 announcements. In any case, the usual disclaimer applies: I currently work for IBM, and this blog post can be considered a "paid celebrity endorsement" of the IBM products mentioned below.)
IBM announced various updates to its Spectrum Storage product line. Here is a quick recap.
Here's a great quote from a leading IT industry analyst:
"In multi-petabyte, multivendor installations, overall storage costs of ownership for use of IBM Spectrum Storage solutions averaged 73 percent less than EMC, and 61 percent less than Hitachi equivalents" -- Brian Jeffery, Managing Director, International Technology Group, Naples, FL
As IBM continues its transition from a hardware-oriented company founded over a century ago, manufacturing meat scales and cheese slicers, to one more focused on higher value-add software and services, the Spectrum Storage software family will play a critical role of this transformation!
