Two years ago, the folks at University of Toronto asked me to help their graduate students build a "Watson" running entirely on IBM SoftLayer to see if this would be a worthwhile class project. Needless to say, it was more difficult than they expected, but we managed to pull it off during that summer, able to answer a handful of simple questions from a single page corpus.
Last month, [Industry Leaders Establish Partnership on AI], combining the talents from Amazon, DeepMind/Google, Facebook, IBM and Microsoft, to form a non-profit to explore best practices and ethical questions related to Watson and other Artificial Intelligence applications.
Since data is at the core of any Artificial Intelligence, IBM is pleased to announce today that IBM Cloud Object Storage System is now available on IBM SoftLayer. This is based on the Cleversafe technology IBM acquired last year.
While other cloud service providers have offered data storage in the cloud, this new offering also allows hybrid configurations with geographically dispersed erasure coding. Unlike RAID which protects against the loss of one or two drives, erasure coding can protect against a larger number of concurrent failures. For example, using an Information Dispersal Algorithm of "7+5", where seven pieces of data are encoded on twelve independent disks, the system can lose up to five disk drives without losing any data.

Combining this with Geographically Dispersed Configuration across three or more sites means that you can lose an entire data center, four of the twelve disks, and still have instant full access to all of your data from eight drives at the other locations. In the graphic, you see two on-premise data centers combined with a third location in IBM SoftLayer.
Today, I met with Teresa Ferraro and Mike Buttrum from FirstRain in their Manhattan office in downtown New York City. IBM recently contracted FirstRain to provide IBMers like myself with analytics on publicly-available news to keep us informed for business meetings. Here's how IBMers can get the most out of this service.
Basically, FirstRain takes a list and generates the best summaries of publicly-available news that are most relevant. You can organize into different channels. Here I have seven channels.
Companies to watch refer to existing or prospective clients that I plan to be talking with soon. Some of my colleagues are assigned to specific clients, so they can set this up once and enjoy the news for the rest of the year. I, on the other hand, meet with different clients every week, so I will be updating this list on a frequent basis.
I have divided the Competitors between major ones, and smaller startups. Since I am often working with business partners and distributors, I made that a separate channel as well.
For product lines, I picked three: Data migration, Data storage solutions, and Software defined storage.
For conferences where I don't know which companies will attend, such as the IBM Technical University, I can set up information by territory. Here is one for Brazil.
I also attend industry-oriented events, so I can pick those vertical markets that might be helpful with dinner conversations. In this example, I chose Energy, Electric Utilities and Gas Utilities.
Once you have your channels configured, you get your results in various sections:
Management Changes lists any changes in top C-level positions, who left the company, who got recently hired.
Key Developments indicates news like mergers and acquisitions and government regulations.
First Reads prioritizes the top six articles for your channel. You can access more, but these six will get you started as you have your morning coffee.
First Tweets gives you the six most relevant tweets, if those articles above were just "TL;DR"
A section on Business Influencers and Market Drivers is interesting to see who the big players are, and what topics are driving the most conversation. Here's an example from my Energy/Electric/Gas channel:
The Most Talked About section covers quotes and commentary about the most talked about companies in your channel.
With most news sources focused on politics, weather and celebrity gossip, it is nice to have a quicker, more focused approach to get the news I need to prepare for my client briefings. Special thanks to my hosts Teresa and Mike for their hospitality!
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year.
Day 4, the last day of the conference, is only a partial day, and many people opted to leave on Wednesday evening, or Thursday morning instead. The breakfast and lunch meals had fewer people than the previous days. Here is my recap of day 4 Thursday breakout sessions.
Building Hyperconverged Infrastructure for Next-Generation Workloads
Supermicro is more than happy to customize these, upgrading the CPU, RAM, disk or networking connectivity as needed. This solution is roughly half the price of Nutanix, and offers a better Next-Business-Day/9am-to-5pm support package .
The last time I was in Las Vegas, I presented this topic at [IBM Interconnect conference]. Back then, I was given only 20 minutes, was placed on the Solutions Expo showroom floor, competing with the noise and traffic of attendees going to lunch.
This time, it was much better, a large room, and a bigger-than-expected audience given that it was scheduled on Thursday morning.
Cloud storage comes in four flavors: persistent, ephemeral, hosted, and reference. The first two I refer to as "Storage for the Computer Cloud" and the latter two I refer to as "Storage as the Storage Cloud".
I also explained the differences between block, file and object access, and why different Cloud storage types use different access methods. I wrapped up the session covering the various storage solutions that IBM offers for all four Cloud Storage types.
IBM Storwize and IBM FlashSystem with VersaStack versus NetApp FlexPod
Norm Patten, part of the IBM Competitive Project Office Storage Team, presented a competitive comparison between VersaStack with IBM storage, versus FlexPod with NetApp storage.
Commodity Solid State Drives (SSD) and Shingled Magnetic Recording [SMR] offer low-cost, high-capacity storage.
However, they have their own set of problems, so IBM is developing software that can be included in IBM Spectrum Accelerate, Spectrum Scale, and Spectrum Virtualize to optimize their utility.
The concept of Log-Structured Array has been around since 1988. The IBM RAMAC Virtual Array back in the 1990s used it. NetApp's Write-Anywhere File System (WAFL) is an implementation of the [Log-Structured File System] general concept.
SALSA combines Log-Structured Array with enhancements borrowed from the IBM FlashSystem design, that I covered in my Monday and Wednesday presentations, to enhance write endurance by as much as 4.6 times!
This was an NDA session, so I cannot blog any of the details.
World-class Flash-optimized Data Reduction and Efficiency with IBM FlashSystem A9000 and A9000R
Tomer Carmeli, IBM Offering Manager for the A9000 and A9000R presented. He presented an overview of these models on Monday, so this session was focused on the data footprint reduction technologies.
Basically, it is a three step process. First, all "standard patterns" are removed. IBM has identified some 260 standard patterns that are 8KB in length, such as all zeros, all ones, or all spaces, and replaces these blocks immediately with a pattern token.
Second, [SHA-1] 20-byte hash codes are computed on 8KB pieces on a rolling 4KB alignment boundary. In other words, if a 64KB block of data is written, bytes 0-to-8KB are hashed an compared to existing hash codes. If no match, then bites 4KB-to-12KB are hashed, and so on. This approach nearly doubles the likelihood of finding duplicates. When a block match is found, the algorithm can replacing them with pointer and reference count.
Third, any unique data that still remains is compressed using Lempel-Ziv algorithm. This is done using the [Intel® QuickAssist]. This co-processor can compress data 20 times faster than software algorithms running on general-purpose x86 processors.
Do you want an estimate of how much "reduction ratio" you may achieve? IBM has developed two estimator tools to help. The first tool is a complete scan for data expected to be dedupe-friendly. It is a slow process, taking 8 hours per TB. This would be ideal for Virtual Desktop Infrastructure or backup copies.
The second tool is the infamous [Comprestimator] that IBM has had for awhile to help estimate compression savings for IBM Spectrum Virtualize storage solutions like SVC, Storwize and FlashSystem V9000. This tool is very fast, looking at only a statistically-valid subset of the data.
The results of both tools are merged, and the result is within five percent accuracy. This allows IBM to offer guidance on which data to place on these new A9000 and A9000R models, as well as offer a "reduction ratio" guarantee.
A client asked me why I bother to attend other sessions, when I probably know most of the material they present. I explained that I can always learn from others. I can honestly say that I learned something new and useful at every session I attended.
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year. Here is my recap of Day 3 Wednesday.
Become your own Storage Consultant
Gary Graham, IBM Field Technical Specialist for Storage, and Brian Pioreck, IBM Client Technical Specialist for Storage, co-presented this session. This session explained how to use IBM's 30-day free trial of IBM Spectrum Control Storage Insights, a cloud-based services offering.
(Note: 15 years ago, I was the chief architect of version 1 of what we now call IBM Spectrum Control. I am pleased to see how well this product has evolved over the years.)
Storage Insights provides a reporting-only subset of the popular IBM Spectrum Control Standard and Advanced editions. It reports on IBM storage devices, as well as any non-IBM devices that are virtualized behind IBM Spectrum Virtualize products like SAN Volume Controller (SVC), Storwize, and FlashSystem V9000.
If you are a storage administrator, consider trying this out for 30 days, get some immediate results. Since it is cloud-based, you only need a Windows, Linux or AIX system to install a "collector" on site. This collector sends data up to the Cloud at one of IBM SoftLayer facilities. The installation process takes only 30 minutes, and you can download the code from the Internet.
If you find Storage Insights valuable, helping you reclaim some unused space, or provide other insight that saves your company money, consider buying the service, for only 250 US Dollars per 50 TB monitored. If you want more than just monitoring and reporting, consider one of the on-premise solutions like IBM Spectrum Control Standard, or IBM Spectrum Control Advanced edition, which provide provisioning and configuration capabilities as well.
Enhance your Security posture with At-Rest Encryption using the latest IBM Spectrum Virtualize
All of the IBM Spectrum Virtualize products support Data-at-Rest Encryption. For direct-attached storage, the 12Gb SAS controller performs hardware-assisted encryption.
For SAN-attached storage via FCP, FCoE or iSCSI back-end devices, IBM uses the [AES-NI instruction set] that comes included in certain Intel CPU processors.
Last November 2015, [IBM acquired Cleversafe] for $1.3 Billion US dollars because Cleversafe has the brand name recognition as the #1 Object Storage vendor the past two years in a row (2014 and 2015). On July 1 of this year, the transformation was complete, and their flagship product was officially renamed to the IBM Cloud Object Storage System, which some abbreviate informally as IBM COS.
Since then, IBM has been busy integrating IBM COS into the rest of the storage portfolio. I explained how IBM COS can be used for all kinds of static-and-stable data, but not suited for frequently changed data, such as Virtual machines or Databases.
Object storage can be access via NFS or SMB NAS-protocols using a gateway product, like IBM Spectrum Scale, or those from third-party partners like Ctera, Avere, Nasuni or Panzura. It can also be used as an alternative to tape for backup copies, and is already supported by the major backup software like IBM Spectrum Protect, Commvault Simpana, or Veritas NetBackup.
A few years ago, I explained to a client that Converged and Hyperconverged were like a pendulum swinging back. Over the past few decades, we have gone from internal disk, to externally attached disk, to SAN and LAN networks.
Each time, we gained more flexibility, greater connectivity and longer distances. Then I explained that Converged and Hyperconverged is like going backwards, the pendulum swinging back to the days of internal and direct-attached storage. The analogy was a hit, and thus this session was born!
IBM offers multiple Converged Systems. IBM PureSystems, PureData, PurePower and PureApplication solutions offer racks of compute, storage and network gear. Last year, IBM collaborated with Cisco to create VersaStack, a converged system that combines Cisco's x86 blade servers and switches with IBM FlashSystem and Storwize products.
IBM also offers Hyperconverged solutions. IBM Spectrum Accelerate allows the compute, storage and network functions run on 3 to 15 VMware ESXi hosts to form a cluster. The cluster can then make iSCSI-based volumes available to other virtual machines running on these same hosts. The volumes can also be made available to servers outside the cluster, such as bare metal servers or other Hypervisors. This is available as software-only, or you can get pre-built system called the Supermicro Hyperconvergence Appliance.
IBM Spectrum Scale provides a clustered file system that allows the compute, storage and network functions to run on 3 to 16,000 machines. Formerly called General Parallel File System (GPFS), IBM Spectrum Scale has been around for over 18 years. Over 200 of the world's largest "Top 500" supercomputers run IBM Spectrum Scale today.
IBM Spectrum Virtualize and IBM Storwize Birds-of-a-Feather
Barry Whyte, fellow blogger and IBM Master Inventor, presented an overview of the latest features, and where IBM is headed in 2017 for the IBM Spectrum Virtualize family of products. Barry now works in Advanced Technical Skills for Storage Virtualization Asia/Pacific Region.
The group then moved to another room offering delicious food and drink, as Eric Stouffer, IBM Director, Storwize Offering Manager and Business Line Exec, presented the future areas that IBM is consider for this product family.
All of this was done under Non-Disclosure Agreements (NDA), preventing me from blogging any details. Back in 2003, Las Vegas started a marketing campaign ["What Happens in Vegas, Stays in Vegas"]. Coincidentally, this is the same year IBM introduced the IBM SAN Volume Controller, the first product in the IBM Spectrum Virtualize family.
This was a long day, but was pleased with the large audiences I had at my sessions.
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year. Here is my recap of breakout sessions on Day 2.
Introducing IBM FlashSystem A9000 and A9000R: Grid Architecture Designed for the Hybrid Cloud
Tomer Carmeli, IBM Offering Manager for the A9000 and A9000R presented. Both models offer data-at-rest encryption, snapshots, remote mirroring, and data footprint reduction, assuming 5.26:1, a combination of pattern removal, data deduplication and hardware-assisted Real-time compression.
The A9000 is an 8U high pod that can fit into existing racks. It comes in 60TB, 150TB and 300TB effective capacity.
The A9000R includes its own 42U rack. The rack is organized as two to six "grid elements" combined with two InfiniBand switches. Grid elements come in 150TB and 300TB effective capacities, giving you up to a whopping 1.8 PB in a single rack!
Similar to the IBM XIV and IBM Spectrum Accelerate offerings, the A9000 and A9000R support Hyper-Scale features. Hyper-Scale Manager lets you manage up to 144 devices on a single pane of glass. Hyper-Scale Mobility lets you move volumes (LUNs) non-disruptively from one device to another.
Different data compresses or dedupes at different ratios. Your mileage may vary. Unless you are evaluating a JBOF (just a bunch of flash) device, there is a great difference between raw, usable, and effective capacity. Raw capacity can be calculated by the size of each chip, times the number of chips. Usable capacity factors out RAID, and any spare capacity set aside for RAID rebuild and garbage collection. Effective capacity indicates the amount of information that can be stored by taking advantage of data footprint reduction technologies, such as compression or data deduplication.
IBM offers three options:
Measured Estimate -- IBM has a set of data reduction estimator tools that can scan your existing data, and estimate your reduction ratio, within 5 percent accuracy.
Competitive Match -- If a competitor had run their own set of estimator tools, IBM might be able to match the reduction ratio, without repeating the analysis, by just reviewing the competitor results.
"Sight unseen" -- without analyzing your actual data, reduction ratio is determine by the type of data (DB2, Oracle, SQL server, etc.), based on experience with similar data at other data centers.
Both A9000 and A9000R models are published at 250 microsecond latency, about 30 times faster than traditional spinning disk, although some workloads actually can run even faster than that. Assuming 5.26:1 reduction, these sell for about $1.50 per effective GB.
Flash Primer - Ready to move from disk storage?
Patricia Crowell, IBM Worldwide FlashSystem Enablement manager, presented. She presented an interesting time line:
First Solid-State Drive (SSD)
First Flash card, such as for digital cameras
First USB stick
Flash used in specialized IT appliances
Flash for the enterprise - Microsoft and UCSD paper on SSD
In 2012, Microsoft Research and University of California San Diego published ["The Bleak Future of NAND Flash Memory"], 8 pages, by Laura M. Grupp, John D. Davis, and Steven Swanson. Here is an excerpt:
"The technology trends we have described put SSDs in an unusual position for a cutting-edge technology: SSDs will continue to improve by some metrics (notably density and cost per bit), but everything else about them is poised to get worse. This makes the future of SSDs cloudy: While the growing capacity of SSDs and high IOP rates will make them attractive in many applications, the reduction in performance that is necessary to increase capacity while keeping costs in check may make it difficult for SSDs to scale as a viable technology for some applications"
IBM disagreed with this bleak assessment, announced it was investing $1 billion US Dollars into this technology, acquired Texas Memory Systems, and has deployed flash throughout its product line. For the past three years, IBM has been the #1 vendor for Flash storage systems.
Patricia offered the following example. What would it take to run 20 million IOPS? Here's a comparison:
Disk systems 15K rpm
Disk systems 7200 rpm
How to migrate from SONAS to IBM Spectrum Scale/ESS using Active File Manager
Paul Schena, IBM Senior IT Specialist, presented his experiences migrating existing SONAS data to new IBM Spectrum Scale or Elastic Storage Server (ESS) deployments. SONAS is going End-of-Service (EOS) on April 30, 2018, so it is never too soon to start this migration.
Paul gave two different methodologies. The first used Active File Management (AFM):
Setup an IBM Spectrum Scale "Gateway Node" in "Independent-Writer" AFM mode. Paul recommends 10 threads per gateway node.
Issue an AFM pre-fetch, disabling the "cache eviction" feature to ensure data remains. AFM transfers the directory structure, file data including sparse files, Access Control Lists (ACL), extended attributes.
Define your exports with no-root-squash and move your user mounts to the new systems
Once all the data is moved, convert the cache filesets to regular filesets
Define your quotas, export settings, ILM policies and rules
Decommision the SONAS
The second used Robocopy and Rsync, which may be required if there is high-latency, long-distance connection that prevents proper AFM connections:
Configure IBM Spectrum Scale CES servers to appropriate NFS and/or SMB protocols
Use Robocopy and/or Rsync as appropriate to move the data to the new system
Decommision the SONAS
Having it all: Hybrid Cloud Storage Services for Block, Power and Backup
Clint Parish, Director of Enterprise Solutions and Services for VSS, and Marc The'berge, Business Development for Supermicro, co-presented this session.
VSS offers POWER8-based Cloud services. They consider themselves "boutique" with POWER8 servers, able to run AIX, IBM i and Linux on POWER applications, but not at the scale and size of larger x86-based clouds like Amazon Web Services or Microsoft Azure.
For IBM i, they attach to IBM Storwize V7000. For AIX and Linux on POWER, they use IBM Storwize V7000 and/or Supermicro Hyperconverged Appliance, a pre-built system based on IBM Spectrum Accelerate.
Supermicro offers three "tee-shirt sizes", their small systems have six nodes, medium with 9 nodes, and large with 15 nodes. Unlike other Hyperconverged systems, the ones from Supermicro include a rack, and are pre-cabled with all the necessary Ethernet switches necessary to make a complete solution.
To offer backup services, VSS uses IBM Spectrum Protect with the Supermicro appliances.
In the evening, we were treated with a concert with Train, known for songs like "Meet Virginia", "Hey Soul Sister", "Calling all Angels" and "Drops of Jupiter". They played all of these, plus covered some songs by Led Zeppelin, Journey, Queen and Aerosmith,
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year.
General Session - Outthink Status Quo
This week's motto is "Outthink the Status Quo.. Before the Status Quo disrupts your business!
Tom Rosamilia, IBM Senior VP for IBM Systems (and my fifth-line manager), kicked off the event. There are about 5,500 people at this event. He mentioned that just like a picture is worth a thousand words, "a prototype is worth a thousand meetings."
He showed a video of our client "Plenty of Fish" [POF], which is a dating site. They have 100 million members, of which 4 million access their site every day. IBM FlashSystem paid for itself, with an ROI payback period of 2 months.
Jason Pontin, Editor in Chief and Publisher of [MIT Technology Review], mentioned three major areas to watch:
Explosive innovation in Artificial Intelligence (AI), including IBM Watson, machine learning, etc.
Pervasive computing, including augmented reality or virtual reality, what IBM calls Internet of Things (IoT)
Re-writing life, directly editing genomes for healthcare and agriculture
Jason feels there are two major challenges for humans. First, what is the "future of work"? People are no longer working for the same company for their entire career. Rather, they come and go, moving in and out of companies. Second, how will we deliver food and water to the 9.6 billion population expected to exist by 2050, with added challenge of climate change. Ed Walsh, IBM General Manager for Storage and Software Defined Infrastructure, presented next. Last year, I was asked to throw my hat in the ring to be the next General Manager of IBM Storage. I was up against some strong competition, and in the end upper management selected Ed Walsh instead. He is a good choice, and I support his efforts.
Matt Cadieux, CIO for [Red Bull Racing], presented on the IT challenges of designing, building and racing Formula One racing cars. They have 21 races per year, and each race has slightly different specifications, forcing Red Bull Racing to break down and rebuild their cars for each race.
Michael Lawley, Senior IT Vice President for [HealthPlan Services], explained how his business grew 300 percent in the past four years. Their workloads are very "spiky", so it is good that they can scale up or down their IT infrastructure 3-4x as needed, within minutes.
Jacob Yundt, CIO for University of Pittsburgh Medical Center [UPMC], explained the importance of genomics as the next frontier of medicine. Genomics allows for more accurate cancer determinations, which helps target specific treatments. They moved from x86-based clusters to those based on Power LC models from IBM. For analytics, they chose IBM Power8 S822L servers with Elastic Storage Server (ESS) and the Hadoop Transparency Layer.
Lastly, Terri Virnig hosted two technology partners to the stage for some major announcements. First, Jim Totton from Red Hat, announced that RHEV v4 (based on Linux KVM) is announced for POWER platform. Secondly, Scott Gnau, CTO for [Hortonworks], announced that Hortonworks will run on the POWER platform, as part of IBM and Hortonworks Open Data Platform [ODP] initiative.
Trends & Directions: The Future of Storage in the Cloud and Cognitive Era
Eric Herzog, IBM Vice President, Product Marketing and Management Software Defined Infrastructure, served as emcee for this session.
Ed Walsh, IBM General Manager for IBM Storage and Software Defined Infrastructure, marveled at IBM's "storied history in storage innovation". He suggests clients should modernize and transform their business with IBM broadest storage portfolio in the IT industry.
Clod Barrera, IBM Engineer and the Chief Technical Strategist for IBM Systems Storage, explained that in the past 60 years of disk systems, areal density has improved by a factor of one billion. Unfortunately, that is slowing down, and we won't see such improvements anymore.
Bina Hallman, IBM Vice President, Software Defined Storage Solutions Offering Management, hosted a panel of clients, including:
Bob Osterlin, from [Nuance], that has 5-10 PB of data using IBM Spectrum Scale for voice recognition software.
Rich Spurlock, from [Cobalt Iron], that provides Backup-as-a-Service using IBM Spectrum Protect. Their clients experience an 80 percent reduction in operating expenditures (OPEX) using Spectrum Protect.
Moshe Perez, from [RR Media], that provides television channel distribution like ESPN and BBC to other countries. They use IBM Spectrum Accelerate to handle the demand peaks, such as the Olympics.
Mike Kuhn, IBM Vice President for Storage Solutions Offering Management, also hosted a panel of clients, including:
Kevin Muha, from [UPMC], managing 13 PB of storage, across a variety of IBM storage devices, including 700 TB of FlashSystem V9000.
Bill Reed, CTO for [Arizona State Land Department], that uses VersaStack with IBM FlashSystem V9000 for geographic information system [GIS] applications. They manage over 9.2 million acres to help fund K-12 schools in Arizona.
Owen Morley, from Plenty of Fish [POF] dating website, evaluated nearly every flash device in the market, and chose IBM FlashSystem. "The one metric that matters is Latency!"
These were the two main keynote sessions on Monday morning. During the rest of the week there will be over 285 storage-related breakout sessions, dozens of labs, and 7 panels.
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year. In previous years, this conference was held in May, June or July, but this year, it was moved back to September, to coincide with the 60th Anniversary of IBM Disk Systems.
I have arrived safely to Las Vegas, and checked in at Edge 2016 Conferenece Registration.
This year, the Solutions EXPO opens early, on Sunday with a reception. This gives people a chance to go to booth #330 to make appointments for one-on-one with various IBM Executives!
I was able to catch up with co-workers I have not seen in a while! There is a whole section on IBM storage products such as the IBM DS8888 All-Flash Array, as well as software products like IBM Spectrum Protect and IBM Spectrum Control.
On Monday, my session "All Flash is Not Created Equal: Tony Pearson Contrasts IBM FlashSystem and SSD" has moved from the tiny room to a much larger room "Studio A". There was a lot of demand for this session, so I have agreed to present this again, as a repeat session, on Wednesday.
Edge will be different in many ways this year. The past few years we had separate "Executive Edge" for C-level executives, "Winning Edge" for IBM Business Partners, and "Technical Edge" for server, network and storage administrators.
This year, all 1,000 sessions are combined back into one, but with clever hints in the titles. The words "General Session", "Outthink" or "Cognitive" are used to indicate C-level executive talks. Those that use the terms "Winning" or "Community" target IBM Business Partners, Managed Service Providers and Cloud Service Providers. Those that mention z Systems, POWER servers, or Storage solutions, often adding the term "Deep-Dive", are technical.
(Unlike other sessions that might appeal to one portion of the audience or another, mine are suitable for everyone, from C-level executives and IBM Business Partners to storage administrators. To help people find them under the new naming scheme, I have added "Tony Pearson Presents", or words to that effect.)
About 260 breakout sessions relate to IBM Storage, but there are only 20 or so time slots, so obviously you can't see them all in person.
I strongly suggest you pick about three to five topics per time slot, so that you are not overwhelmed by the dozens of choices during the event. This allows you to make a quick decision on which one you finally decide on during each time slot.
Occasionally, a session might get canceled, postponed, or be so full of attendees that nobody else is allowed in, so having three to five topics selected allows you to chose an alternate.
Here is my schedule for next week at Edge 2016.

For those interested in a one-on-one meeting with me, over breakfast, lunch or dinner, or some other time, I have several slots still available. Fill out a request form on BriefingSource at: [https://briefingsource.dst.ibm.com/]
As I have mentioned before, I started this blog on September 1, 2006 as part of IBM's big ["50 Years of Disk Systems Innovation"] campaign. IBM introduced the first commercial disk system on September 13, 1956 and so the 50th anniversary was in 2006. That means this month, IBM celebrates the "Diamond" anniversary, 60 years of Disk Systems!
For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
You can read more about it www.ibm.com/storage/tape."
Short and sweet, but it got me started, and I ended up writing 21 blog posts that first month. You can read blog posts from all 10 years by looking at the left panel of my blog under "Archive".
While traditional disk and tape storage are still very important and relevant in today's environment, IBM has also expanded into other technologies:
In 2012, IBM [acquired Texas Memory Systems]. In 2014, IBM shipped 62PB, more Flash capacity than any other vendor. In 2015, continued its #1 status, shipping 170PB of Flash, again, more than any other vendor.
IBM has flash everywhere, from the advanced FlashSystem 900, V9000, A9000 and A9000R models, to other all-flash array and hybrid flash-and-disk systems a with various sets of features and functions to meet a variety of workload requirements.
The DS8888 all-flash array, and the DS8886 and DS8884 hybrid flash-and-disk systems round out the latest in the DS8000 storage systems family. SAN Volume Controller and Storwize family of products, based on IBM Spectrum Virtualize software, also have all-flash array and hybrid configurations. The most recent being the Gen2+ models of Storwize V7000F and V5030F. The latest solution is the DeepFlash 150 models, designed for analytics and unstructured data.
Between internally-developed IBM Spectrum Scale and IBM Spectrum Archive, and IBM's [acquisition of Cleversafe], IBM is ranked #1 in Object Storage. IBM Cloud Object Storage System, IBM's new name for Cleversafe's flagship product, is available as software-only, pre-built systems, or in the IBM SoftLayer cloud.
Software-Defined Storage (SDS) with IBM Spectrum Storage
Last year, IBM re-branded its various storage software products under the "IBM Spectrum Storage" family. Earlier this year, IBM announced the new [IBM Spectrum Storage Suite license] which makes it even easier to procure, either with a perpetual software license, elastic monthly licensing, or utility license that combines some of each.
IBM is ranked #1 in Software-Defined Storage, with over 40 percent marketshare, offering solutions as Software-only, pre-built systems, and in IBM SoftLayer cloud.
Well it's Tuesday again, and you know what that means? IBM announcements!
(For those wondering where I went in July, then perhaps the better question should be "where didn't I go?". I started in Boston, MA, then Iceland, England, Hungary, Romania, Qatar, Kenya, Dubai UAE, and finally Seattle, WA. Whew! This week, I am visiting clients in Tennessee.)
Today, IBM launches a whole set of updated offerings based on the IBM Spectrum Virtualize software code base.
IBM Spectrum Virtualize v7.7.1 software-only offering
Like the rest of the IBM Spectrum Storage family of products, IBM Spectrum Virtualize can now be purchased as software only, allowing you to install it on your own x86 servers, rather than purchasing pre-built systems from IBM.
The software license comes in two flavors. The traditional "perpetual license" allows you to move the software from one x86 server to another. Say after 4 years, you have depreciated the server, or the hardware components fail, and you want to get a newer server. This is the same perpetual license that clients with IBM SAN Volume Controller and Storwize family have enjoyed since 2003.
The other is a "monthly license", which allows you to stand up your own "SVC" using your own x86 servers, for a period of months needed for a development/test project, disaster recovery, or some other purpose. After the project is over, you can discontinue the license, and re-purpose the x86 servers for something else. This is especially handy for Managed Service Providers (MSP) and Cloud Service Providers (CSP), but certainly can prove useful in traditional datacenters as well. The "monthly licensing" option is also available for IBM SAN Volume Controller (SVC) as well.
The software license is based on Tebibyte [TiB]. For those not familiar with international standards, here is a comparison table:
The v7.7.1 also provides new features for existing SVC, Storwize and FlashSystem V9000 products. Here are a few:
Manageability with CLI support for host groups
Scalability with support for up to 10,000 virtual disks, depending on the model; and up to 20 Expansion Enclosures on SVC 2145-DH8, Storwize 5639-SV1, FlashSystem V9000 models
RAS and performance enhancements for distributed RAID (DRAID)
Flexibility with iSCSI virtualization support for XIV® Gen 3, Spectrum Accelerate, FlashSystem A9000 and FlashSystem A9000R arrays.
The IBM SAN Volume Controller now offers "Enterprise Class Support" as an option. In the past, the SVC was a "customer setup" box, similar to midrange and entry-level products. Now, you can upgrade your support to match that of IBM DS8000 and XIV enterprise class offerings. This means that IBM experts will maintain your microcode levels for you.
The new 624 model is based on the 10-core [Intel Broadwell] processor, which IBM has clocked at up to 45 percent performance improvement. It also offers up to 128GB of cache memory per system, 64GB per node, double what came standard on the 524 model!
Why "Gen2+"? Moving from an 8-core Haswell to a 10-core Broadwell CPU, and doubling the cache memory didn't seem to be enough "architectural change" to justify calling in a "Gen3", so marketing decided on Gen2+ instead.
I refer to the IBM FlashSystem V9000 as my "Superman" product. When Superman dons on his glasses he becomes "Clark Kent", mild-mannered newspaper reporter. But behind the glasses, he is always Superman! Likewise, the FlashSystem V9000 is an all-flash array with an impressive set of features, but take off the fancy bezel, and you find that it is a pair of fully-loaded SAN Volume Controllers (which we call "Control Enclosures AC3") and a FlashSystem 900 drawer of the world's fastest flash storage.
The FlashSystem V9000 can attach up to 20 expansion enclosures over 12Gb SAS connections. Each expansion enclosure can hold either 24 of the smaller 2.5-inch drives, or 12 of the larger 3.5-inch drives. Of course, the FlashSystem V9000 can also virtualize any of almost 400 other storage arrays, similar to SAN Volume Controller. This provides tiering options that match well with the FlashSystem 900 inside using IBM's Easy Tier auto-tiering capability.
IBM Storwize V7000F and V5030F all-flash array models
The FlashSystem V9000 was originally going to be called the Storwize V9000, but the FlashSystem folks wanted to keep all of the "FlashCore" technology under one name. In perhaps a bit retaliation, or maybe sibling rivalry, the Storwize team added the letter "F" to refer to the All-flash models of the Storwize V7000F and V5030F.
The "flash" in the V7000F and V5030F are just Solid-state drives, not nearly as fast as the cards in the FlashSystem models. The drives come in 1.92TB and 3.84TB capacities. You might see these rounded up to 2TB and 4TB on some presentations, but IBM officially never likes to exaggerate.
Last week, I presented at the "IBM TechU Comes to You" event in beautiful Nairobi, Kenya. This was a three-day event, so here is my recap of Day 3, Thursday Aug 4, 2016.
Business Continuity and Disaster Recovery for z Systems
I have been working in Business Continuity and Disaster Recovery my entire career at IBM, so when I was asked to give a "z Systems" mainframe slant to my standard BC/DR pitch, I was up to the challenge. IBM offers a complete set of solutions, and I presented best practices for each.
Data Protection, Management and Journey to the Cloud with IBM Spectrum Protect
This session was presented by Saumil Shah, IBM Spectrum Protect Sales Leader for Middle East, Turkey & Africa. I am glad that Saumil volunteered to cover IBM Spectrum Protect, as I already had six sessions on my plate for this week. My version tends to focus on the "What and How" of data protection, whereas Saumil focused instead on the "Why" of data protection. Why should you protect data, and why you should use IBM Spectrum Protect instead of the various other software out in the marketplace.
IBM Spectrum Virtualize - Understanding SVC, Storwize and the FlashSystem V9000
IBM Spectrum Virtualize is the new name for the code base shared by all of these products. I presented the latest features of SVC, Storwize and FlashSystem V9000 hardware models, as well as the latest software features.
How to combine the advantages of Storage Virtualization and Flash performance (the Turbocompression effect)
This session was presented by Dominique Salomon, IBM Certified IT Specialist Storage and European New Technology Introduction Leader. He works at the IBM Montpelier Briefing Center in France, a sister organization to the IBM Tucson Executive Briefing Center that I work in. The term "Turbocompression" was initially coined by his team in Montpelier to explain the combined benefits of Flash technology, Easy Tier automated sub-LUN tiering, with Real-time Compression.
I have to admit that the first time I heard this, I was skeptical. It sounded like a marketing gimmick to mention these together. However, once I saw the demo and the resulting numbers, I was convinced. IBM Easy Tier technology identifies and ranks which blocks are the busiest, and moves extents to the appropriate place. Real-time Compression can compress data in cache memory, flash and spinning disk, allowing more of the busiest blocks of data to reside in the fastest storage media. This means higher hit ratios for cache, lower latency for flash, and less wear-and-tear on the spinning disk drives.
Storage Integration with OpenStack
While OpenStack is used by more than 60 percent of Cloud Service providers, it is used by fewer than 10 percent of the Fortune 500 corporations. This represents an excellent opportunity for IBM, leading in having its storage products support this important open source interface.
IBM supports OpenStack Cinder interface for its block level devices, including DS8000 and XIV. IBM Supports OpenStack Swift for its object storage, including IBM Spectrum Scale, IBM Spectrum Archive, and IBM Cloud Object Storage System (formerly Cleversafe). IBM Spectrum Scale supports OpenStack Cinder, Swift, and Manila interfaces for a complete solution across volumes, files and objects.
Marlin Maddy, IBM Manager of Worldwide Systems Technical Events, served as master of ceremonies. He thanked the audience for attending, and drew names for prizes. This time these were Samsung "smart-watches".
Thursday evening, some people left, and the few of us remaining had dinner at the Intercontinental Hotel. I joined folks from USA, Germany and Middle East. I love our informal discussions! I learn so much listening to other points of view.
Last week, I presented at the "IBM TechU Comes to You" event in beautiful Nairobi, Kenya. This was a three-day event, so here is my recap of Day 2, Wednesday Aug 3, 2016.
IBM Spectrum Scale overview and update
This session was covered by Mack Kigada, IBM Executive Consultant for the "Executive Advisory Practice" portion of Systems Lab Services. This session explained the basic features of Spectrum Scale, including the latest features of version 4.2, and related Elastic Storage Server pre-built systems.
Software Defined Storage - IBM Spectrum Overview
This session was presented by Saumil Shah, IBM Spectrum Protect Sales Leader for Middle East, Turkey & Africa. Since SDS is an important topic, the conference coordinators schedule several speakers to present at different time slots, to give everyone a chance to hear the SDS message. Rather than using my same charts, Saumil used his own deck, which he customized based on his experience working in this region.
Flash and the Next Generation Data Center
This session was covered by Firat Ozturk, IBM FlashSystem Sales Leader for Middle East, Turkey & Africa. While IBM offers all-flash array versions of its DS8000, SVC and Storwize product lines, Firat focused on the IBM FlashSystem family, including the FlashSystem 900, FlashSystem V9000, and the new A9000/A9000R models.
According to IDC, Flash-based technologies are predicted to represent 50 percent of the storage capacity sold in 2018. Today it is about 10 percent, so that is a big leap. The primary reason he feels are new applications like Cloud and Mobile that are driving customer expectations to faster performance.
Which product should you get? Firat indicated that the FlashSystem 900 is ideal to boost the performance of specific applications, like Oracle or SAP HANA. The FlashSystem V9000 borrows all the code base from SVC and Storwize with Real-time compression ideal for OLTP and Database applications, while offering Storage Virtualization to protect your existing storage infrastructure investment. The FlashSystem A9000 and A9000R are targeted to Cloud deployments, as well as Server Virtualization and Virtual Desktop Infrastructure (VDI).
What is Big Data? Architectures and Practical Use Cases
I have been presenting this since 2013, but still draws a new crowd every time. Based on my [2015 Presentation], I made some updates to reflect IBM's latest support for Spark, and the new POWER8 solution offerings.
Storage Tiering on z Systems: Less Management, Lower Costs, Less Management, and Increased Performance
When I present Storage Tiering for distributed systems, I typically focus on Easy Tier feature of SAN Volume Controller, the Analytics-based storage optimization of Spectrum Control, and the Information Lifecycle Management (ILM) policies of Spectrum Scale and Spectrum Archive. This time, Glenn Anderson asked me to give this a "z Systems" slant, for a mainframe-oriented audience.
In this new version, I focused on Easy Tier on IBM DS8000 systems, Hierarchical Storage Management in DFSMShsm, and the new Class Transition features that were introduced initially with DFSMSoam for objects, and now extended for data sets.
Linux on IBM z Systems and its Participation in Open Source Ecosystem, including Blockchain
Wow! What a long title!
This session was presented by Holger Smolinski, IBM Senior Performance Analyst Linux and KVM on IBM z Systems from the Boeblingen, Germany Lab. Back in the late 1990s, Holger and I worked on porting Linux to the S/390 platform. I led a team to test all of the device drivers for IBM disk and tape storage systems, working with Holger and his team to fix the drivers and submit them to the Open Source Community, so that they would be incorporated formally into the latest Red Hat and SUSE distributions.
Holger gave quite an extensive overview of the entire Open Source Ecosystem that run on Linux on z System mainframes. Over 60 percent of new mainframe customers use Linux on z Systems operating system, and the complete set of capabilities, makes this quite practical.
One of the latest of these is [Blockchain], a new way to track transactions between organizations. The open source project for this is [HyperLedger]. Transactions are recorded into blocks that are encrypted with a hash code, which prevents tampering and fraud. These blocks are then chained together as transactions occur between organizations.
For example, if a product is manufactured in China, shipped over the Pacific Ocean by a shipping company, received at a port in the United States, processed by US Customs, then shipped via trucking company to the buyer, these all would be represented as transaction blocks chained together.
Wednesday we had free evening to explore on our own. Some of my colleagues went to an all-you-can eat steakhouse for dinner, but I will get plenty of that in my upcoming trip to Sao Paulo, Brazil, so went elsewhere.
Last week, I presented at the "IBM TechU Comes to You" event in beautiful Nairobi, Kenya. This was a three-day event, so here is my recap of Day 1, Tuesday Aug 2, 2016.
Opening Keynote Session
Once again, Marlin Maddy, IBM Manager of Worldwide Systems Technical Events, served as master of ceremonies. He arrived into Nairobi just a few hours earlier, and we were worried that one of us might have to jump in and take over if he had any delays in his flight schedule. Fortunately, he arrived and did a great job welcoming the audience.
Eric Jaoko, chief manager of Kenya's Rural Electrification Agency [REA], presented next. Back in 1973, the Kenyan government wanted to have all of its rural areas offering electrical service. Some 30 years later, in 2002, only 4 percent of the rural areas had achieved this. In 2006, the Kenyan government formed this new REA agency to accelerate the progress. By 2008, nearly 25 percent of rural areas were electrified. Currently (2016), they are now at 68 percent, including all primary schools (more than 20,000 across the country).
Eric mentioned that this success was in part to their partnership with IBM for Information Technology. REA switched from Oracle to SAP applications on IBM Power systems with IBM Storwize V7000, resulting in lower costs, less power consumption, easier to deploy and manage, redundancy and high availability, scalability and high speed access to critical data. Not surprisingly, IBM's leadership in "Mobility" plays another key role, since these areas are rural and often connected only by cellular phone service.
REA employees both AIX and Linux on POWER operating systems, and uses OpenStack to manage both the servers and storage components. PowerVM, PowerVC and PowerHA complete the solution to provide a more robust environment. REA found it was very easy to clone their SAP systems, which made it very easy to test software upgrades without impacting their production environments.
The next speaker was IBM's own Glenn Anderson, IBM z Systems Consultant and Worldwide Technical Events Content Manager. His talk was titled "Think Outside the Cubicle" to emphasize that there are changes underfoot in the IT industry. Rather than focusing on IT as a cost to be reduced, enlightened CEOs are discovering that IT can be used to optimize value for their organization.
One trend that has changed drastically is what IBM refers to as "Systems of Engagement". To better connect with clients, customers and suppliers, organizations now create conversations on social media channels, listen and react to those conversations, building communities that allow them to better understand and serve their markets.
Another trend was "Two-speed IT", often called "Bimodal IT", which indicates that some projects should have "fast-track" status, streamlining the process of design, development and deployment for new innovations. This is in contrast to traditional "slower" projects for mission critical "Systems of Record" operations, like databases and Online Transaction Processing (OLTP).
His last trend he covered was this notion of "Cognitive Business", the use of self-learning, natural language processing to assist in business decision making. Glenn compared the old way as a static map that indicated "You Are Here". The new way was more like GPS, which indicated where you are, where you want to be, and the steps to get there.
(You might ask "Why do business leaders need such assistance?" First, business executives cannot ingest and comprehend the vast amount of data they need to make correct decisions, causing them to make less-than-optimal choices with limited information. Second, business leaders are often only on the job a few years, moving around from one opportunity to another, and do not build the experience background that a computer that can ingest millions of documents can achieve much more quickly. Third, business leaders often are prone to bias, surrounding themselves with ["yes-men"], unwilling to accept any information that contradicts their world view. Computers do not have that bias, and are capable in finding insights, trends and patterns that business leaders might not have considered.)
Software Defined Storage -- What? Why? How?
I was honored to be asked to be the keynote kick-off for the IBM Storage track of this conference. There is still much confusion over the concept of Software Defined Storage (SDS). While there are many different positions on this, IBM has adopted the IDC definition, which requires all three criteria to be met:
Solutions based on Industry-standard, off-the-shelf components.
Solutions that offer the complete set of storage features and functions, such as point-in-time copies, data footprint reduction, technical refresh migration, and remote replication.
Solutions that are offered in multiple ways, such as software-only, pre-built systems using industry-standard off-the-shelf components, and cloud-based services.
IBM's SDS offerings include all of the IBM Spectrum Storage family available as software-only, pre-built systems like SAN Volume Controller and XIV Gen3, and cloud-based services like IBM Cloud Managed Backup and Archive, and IBM Cloud Object Storage System (formerly Cleversafe).
IBM ranks #1 in SDS marketplace, with over 40 percent marketshare. The advantage of IBM's approach is that it does not require a complete rip-and-replace of existing IT infrastructure. IBM solutions can work with your existing servers and storage that you have already in place! This allows for a smooth and graceful transition.
Cloud Computing Concepts and the Role of Infrastructure
This session was covered by Mack Kigada, IBM Executive Consultant for the "Executive Advisory Practice" portion of Systems Lab Services. Frankly, I think this should have been classified as a "Cross-Brand" rather than other "Storage", as it showed not just storage but also how servers and OpenStack participate in a complete Hybrid Cloud solution.
The new IBM FlashSystem A9000 GUI
This session was presented by Dominique Salomon, IBM Certified IT Specialist Storage and European New Technology Introduction Leader. He works at the IBM Montpelier Briefing Center in France, a sister organization to the IBM Tucson Executive Briefing Center that I work in.
When IBM was ready to launch its newest FlashSystem offering, which combines the low-latency IBM FlashCore technology from IBM FlashSystem 900 with the IBM Spectrum Accelerate software from XIV, they had to decide what Graphical User Interface [GUI] to deploy it with. The IBM development team had narrowed it down to three options:
Use the IBM XIV Gen3 GUI, which is installed client code that runs on a handful of select operating systems. This GUI is nine years old.
Adopt and modify the browser-based GUI used by all of the other IBM Storage systems like DS8000 and SAN Volume Controller. By using HTML5, AJAX and Dojo widgets, this newer approach eliminates Operating System and Java dependencies, and can run on desktops, laptops, tablets and smartphones. However, this technology is four years old.
Deploy a new GUI, adopting the latest techniques and methods, offering a new, simpler way to manage the new device.
The development team decided on the third option, and so Dominique spent the first half hour explaining what the IBM FlashSystem A9000 and A9000R systems are, and then the last half showing a live demo connecting back to his systems in Montpelier, France.
IBM XIV, Spectrum Accelerate and the new IBM FlashSystem A9000
This session was covered by Maurice "Mo" McCullough, IBM Storage Technical Content Leader for IBM Systems Worldwide Technical Events. In retrospect, he admitted that he should have scheduled this session before Dominique's session above, which would have reduced the amount of time and questions Dominique spent explaining the IBM FlashSystem A9000 and more time showing the new GUI.
Mo first covered the newest model of the XIV Gen3 pre-built system, the model 314. It has double the cache memory and double the processing cores to drastically improve Real-time compression. Then, he explained IBM Spectrum Accelerate, available as either software you can deploy on your own x86 servers on-premises, or in cloud-based servers from IBM SoftLayer. Finally, Mo covered the A9000 and A9000R, the newest members of the IBM FlashSystem family that share features and capabilities with the XIV Gen3 and Spectrum Accelerate offerings.
Tuesday evening we had a welcome reception for all the attendees, staff and speakers. This was a great time to relax and meet everyone on a social level.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
New Nearline expansion enclosures for FlashSystem V9000 and SAN Volume Controller (SVC)
The new 12 Gb SAS expansion enclosure expands total capacity and delivers a tiered data solution. Each LFF expansion enclosure supports twelve 3.5-inch 8 TB NL-SAS drives. Up to two expansion enclosures are supported by a FlashSystem V9000 or SVC controller pair, delivering up to twenty-four drives and 192 TB of raw capacity. The capacity can be compressed up to 5x (80 percent savings) using IBM Real-time Compression.
IBM Spectrum Control and IBM Virtual Storage Center V5.2.10 release
IBM Spectrum Control continues its quarterly continous delivery model with version 5.2.10 release. This is also included in all variants of IBM Virtual Storage Center which bundles IBM Spectrum Control with IBM Spectrum Virtualize products. New features include:
View more details about capacity growth over time for storage systems, pools, volumes, fileset, and file systems. This helps capacity planners to plan for future purchases and procurement.
Aggregate basic information across multiple Spectrum Control servers into a single place, rolling up information was temporally removed in Spectrum Control V5.2.8 and is now available in the web-based GUI for the first time. This is intended for clients to manage multiple data center sites, but can also be used to Cloud Service Providers and Managed Service Providers to generate reporting across a group of clients.
Compare the workload and performance characteristics of IBM SAN Volume Control and IBM Storwize systems against best practice performance guidelines. This is especially useful synergy for the IBM Virtual Storage Center bundles.
Export performance data for storage systems and fabrics using a new Create Performance Support Package wizard. This is helpful in case you observe a performance problem with your IBM storage system, and the IBM support for that device would like to receive the measured performance statistics for further analysis. In the same manner that IBM Spectrum Control drastically reduces troubleshooting time for clients, it is also proven useful for IBM support teams.
Understand how the capacity of storage systems is used when storage virtualization is implemented in the environment, by looking at the information about virtualized and non-virtualized capacity. This allows storage administrators to show upper management how their investment in IBM Spectrum Virtualize (SVC, Storwize, etc.) has returned on investment.
Launch the IBM Spectrum Scale GUI from IBM Spectrum Control to deliver an even better integration of the two products.
It is hard to believe I was the "Technical Evangelist" for SAN Volume Controller when it launched in 2003. That was 13 years ago! Since then, a variety of products using the shared codes base (IBM Spectrum Virtualize) have launched, including IBM Storwize family and IBM FlashSystem V9000 mentioned above. The new IBM Spectrum Virtualize Software V7.7 delivers the following improvements:
Reliability, availability, and serviceablility with NPIV host port fabric virtualization. This is actually pretty cool feature. NPIV stands for "N-port ID Virtualization". Every Spectrum Virtualize port has an N-port ID, and if one node fails, multi-pathing software must scramble to look up its partner node and re-direct traffic to the ports of that other node. With NPIV, the partner node takes on the N-ports of both its own node, as well as the failed node, and handles all the traffic, and then gives back the N-ports back to the other node when it is back up and running.
Distributed RAID (DRAID) support for encryption. IBM added support for distributed RAID-5 and RAID-6 in the previous release, but at the time did not include the built-in encryption feature for these new kind of RAID ranks. Now it supports encryption.
Graphical User Interface (GUI) enhancements to manage your IP-based quorums. Previously, if you had a two-site configuration like Stretched Cluster or HyperSwap, best practices would require a third location as "tie breaker". Thus, people ran fiber optic cables from both sites to a third location, with a small disk system in a closet somewhere. The IP-based quorum is a little Java program you can run on any system, and so long as both sites have LAN or WAN access, serves the same role.
Graphical User Interface (GUI) enhancements to run the "Compresitmator" tool. The Comprestimator tool can run against existing volumes (vDisks) to identify estimated compression savings.
Flexibility Virtualization of iSCSI-attached and Fibre Channel-attached external Storage arrays. Previously, only Fibre Channel (FCP and FCoE) back-end devices could be virtualized. Initially, this will support iSCSI virtualization of IBM Storwize and Dell EqualLogic.
Performance with 64 GB read cache. The software code was enhanced to take advantage of 64-bit memory addressing to support larger read cache.
Software licensing metrics to better align the value of SVC software with Storage use cases through Differential Licensing, based on Storage Capacity Unit (SCU). The licensing for SVC has base and compression license based on the back-end (managed physical usable capacity), and then various features that are based on the subset of front-end capacity (virtual volumes). The new Differential Licensing applies SCU to the back-end (base license and compression). The front-end features continue to be TB-based.
IP Link compression to improve usage of IP networks for remote-copy data transmission
Differential Licensing based on Storage Capacity Unit (SCU)
Differential licensing based on new concept IBM calls Storage Capacity Unit (SCU). Previously, software was licensed per Terabyte (TB), but that treated all TB the same, from Flash to Nearline disks. The new license method takes storage media into three categeories:
1 SCU equals 1.00 TB of Flash and Solid-State Drives (SSDs), and any other storage not listed in the categories below.
1 SCU equals 1.18 TB of 10K and 15K rpm drives, such as Serial Attached SCSI (SAS) Drives and Fiber Channel Drives, as well as systems using "Category 3" (Nearline or SATA drives) with advanced architectures to deliver high-end storage performance, such as IBM XIV Storage System, HP 3PAR or Infinidat .
1 SCU equals 4.00 TB of 7200 rpm Nearline SAS (NL-SAS) and Serial ATA (SATA) Drives
This new licensing is experimental. I would be interested in your feedback.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
Last week, IBM announced a variety of tape system enhancements.
IBM TS7760 Virtual Tape System
The IBM TS7760 combines the benefits of the previous TS7720 and TS7740 offerings. Those with IBM z System mainframes will recognize both. The TS7740 has a small amount of disk that pretend to be a tape library, with enough capacity to hold a few hours to a few days worth of data. After that, the data is moved to physical tape. The TS7720 is an all-disk solution, holding up to 1 PB of disk to hold weeks or months worth of data, but did not have tape attachment. Previously, IBM announced the TS7720T, a high-capacity offering with tape attachment. The new TS7760 is now the replacement for all three of these, powered by the latest POWER8 processor.
In addition to all the features available in the former models, the new TS7760 uses 4TB drives instead of 3TB drives, resulting in a maximum capacity of 1.3PB of disk capacity before compression. The disks are encrypted and protected by distributed RAID-6 referred to as "Dynamic Disk Pooling". While tape attachment is still optional, it supports both IBM TS3500 and TS4500 tape libraries.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM ProtecTIER TS7650G model DD6 supports File System Interface (FSI)
The IBM ProtecTIER Data Deduplication appliance (TS7620) and gateway (TS7650G) support three protocols used by major backup software products:
VTL - Virtual Tape Library. Originally, backup software products were designed exclusively to work with tape drives and libraries. To introduce disk-based storage and data deduplication, the easiest way was for disk-based systems to pretend to be a tape library. Hence, "Virtual Tape Library" acts just like a physical tape library.
OST - OpenStorage Technology API, a proprietary interface used exclusively by the Veritas NetBackup software to talk to disk-based backup repositories.
FSI - File System Interface, which are your familiar NAS interfaces like NFS and SMB (formerly known as CIFS). Some backup software like Commvault Simpana are optimized for NAS storage pools.
In the past, FSI was limited to the single-controller models. This is because having an active/active file system sharing was very complicated to implement.
In the new DD6 dual-controller model, you can now run two independent FSI instances, each controller owns its own set of files. To learn more, see the IBM Press Release [IBM ProtecTIER DD6 supports FSI].
IBM TS3000 System Console enhancements
The Tape Storage System Console (TSSC) is a console that allows administrators to manage up to 24 systems in tape libraries (such as TS3500 and TS4500) and virtual tape systems (such as TS7720T and TS7650G). The new features include:
Error-initiated problem reporting, often called "Call Home" support, with staged, error-specific data gathering for support
Automatic wellness checking
Remote services such as remote monitoring support and call-in capability with authenticated access through a modem or broadband, including file transfers and multiple connections with attached systems
IBM offers two sets of products for entry-level and midrange disk systems:
Storwize V7000 and V5000 products are optimized for random-access workloads like Virtual Machines (VMs), Databases, Email and other Online Transaction Processing (OLTP).
The DCS3860 and DCS3700 are optimized for sequential throughput, like video streaming, batch processing or big data analytics.
Prior to this announcement, the DCS3700 and DCS3860 supported 4TB and 6TB Nearline 7200 rpm drives, and 800GB and 1.6TB Solid-State Drives (SSD). Obviously, it doesn't make sense to offer SSD on sequential-oriented solutions. To align better with this worldview, IBM is discontinuing the SSD options, and adding a new 8TB Nearline drive option.
IBM Spectrum Control Advanced Edition and IBM Virtual Storage Center
Earlier in my career, I was the chief architect of what is now called IBM Spectrum Control. If you still have IBM Tivoli Storage Productivity Center (TPC) Standard Edition V4.x products, you can now migrate to IBM Spectrum Control Advanced Edition V5.2 by ordering a trade-up part number through Passport Advantage.
IBM Virtual Storage Center (VSC) Entry uses a per-TB pricing model. This is a discounted version of VSC "Classic" for those with four or fewer SAN Volume Controller (SVC) node pairs, and 500 TB or less managed storage capacity per enterprise.
I love Hollywood movies where the main character joins the [Witness Protection Program]! For those not familiar, this is when a person witnesses a horrible or obscene crime. To protect the witness from the criminals, the US Government would change your name, create a new identity, and move you to a new city until the trial is over. While this hides the witness from the bad guys, it also means losing touch with all your friends and family.
I mention this because every time IBM renames an existing product, modifies the code to meet IBM standards, translate to other international languages, and all the other activities needed to [assimilates the product into the IBM "Borg"], it is very similar to joining the Witness Protection Program.
(Internally, we refer to this renaming and assimilating as "blue-washing", not to be confused with the traditional definition of "bluewash" -- To tout a corporation's commitment to social responsibility, and to use this perception for public relations and economic gain; to present a humanitarian front in this manner, which IBM also does. See this article [Sesame Workshop and IBM Watson Team Up to Advance Early Childhood Education] for an example.)
Last November 2015, [IBM acquired Cleversafe] for $1.3 Billion US dollars because Cleversafe has the brand name recognition as the #1 Object Storage vendor the past two years in a row (2014 and 2015). Unfortunately, Cleversafe has "witnessed" a huge rise in obscene profits and revenues, and is now joining the "Witness Protection Program".
Renaming Cleversafe software, pre-built appliance hardware, and related cloud services to [IBM Cloud Object Storage System] is like someone acquiring the Coca-Cola company and renaming their namesake soft drink product to "Brown Carbonated Sugar Liquid", which adults might shorten to "Bro-Carbo" and the kids would nickname "Sugar-Liq".
(FCC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement" for IBM Storage products. I have no financial interest in the Coca-Cola Company, CBS Television, Paramount Pictures, or Warner Bros. I have no knowledge of any IBM's future plans in acquiring any beverage-based manufacturing or bottling companies. I use Coca-Cola® merely as a well-recognized brand for illustrative purposes.)
Honestly, I don't know if "IBM Cloud Object Storage System version 3.8" offers any new features over "Cleversafe 3.7", or if the numbering change was just to help avoid confusion with existing v3.7 clients.
The IBM 3592 Tape Controller Model C07 which provides FICON access for mainframe attachment did not meet the Restriction of Hazardous Substances [RoHS] directive. This is the directive to not have lead-based paint or other hazardous substances in the paint, plastic or other materials in IT equipment.
IBM had a tough business choice. Either fix it, or stop selling it. Our mainframe clients just don't use physical tape anymore. Instead, IBM offers IBM Virtual Tape Systems (TS7720, TS7720T and TS7740) as well as the IBM ProtecTIER TS7650G Mainframe Edition.
In journalism, this is called [burying the lede]. IBM has combined the world's fastest storage, IBM FlashSystem 900, with IBM FlashSystem® A9000/A9000R Software V12.0, based on IBM Spectrum Accelerate and XIV v11 software technology.
This new software has many of the features you love from IBM Spectrum Accelerate and XIV, but adds excellent data footprint reduction. First, we eliminate repeated patterns, then apply data deduplication, and finally apply advanced compression.
This combination works great for Virtual Desktop Infrastructure, Virtual Machines for traditional applications, and even databases. Since this applies to all data, the models are priced based on their "effective capacity" based on 5.26x reduction. Different data dedupes or compresses at different rates. Your mileage may vary.
Two models were announced:
FlashSystem A9000 - This is an 8U rack-optimized solution that has three 2U x86 servers combined with a 2U drawer of FlashSystem 900 with a nice bezel on the front. This can fit into any standard 19 inch rack. Since FlashSystem offers 1.2TB, 2.9TB and 5.7TB IBM Microlatency modules, the FlashSystem A9000 is offered in 60TB, 150TB and 300TB effective capacities. Performance is at least 250 microsecond latency, up to 4.5 GB/sec throughput and 50,000 IOPS.
FlashSystem A9000R - The "R" on the end refers to "Rack". Instead of something that slides into an existing rack, the A9000R is a free-standing 19-inch wide rack with two to six flash enclosures. Each flash enclosure will have two x86 servers running the IBM FlashSystem A900R Software v12.0, and one FlashSystem 900 drawer. IBM offers both 150TB and 300TB effective capacity per flash enclosure, based on the 2.9TB and 5.7TB IBM Microlatency modules. Performance is at least 250 microseconds, up to 18 GB/sec throughput and 2 million IOPS.
Some have called these new models the "All-Flash" version of XIV, in much the same way that the FlashSystem V9000 is the all-Flash version of SVC. That is a reasonable analogy.
This week, I presented at the "IBM TechU Comes to You" event in beautiful Dubai, United Arab Emirates. This was a three-day event, so here is my recap of Day 3.
IBM Spectrum Control Family - The right products for your storage management needs
Mike Griese (IBM Spectrum Storage Evangelist) presented the IBM Spectrum Control family. There are now four editions of IBM Spectrum Control:
IBM Spectrum Control Based Edition -- comes included with specific IBM Storage products to provide Cloud APIs such as those required for VMware.
IBM Spectrum Control Standard Edition -- Includes "Based Edition" and adds monitoring, provisioning and troubleshooting for IBM and non-IBM storage devices. Also includes IBM Copy Services Manager for select IBM storage devices.
IBM Spectrum Control Advanced Edition --Includes "Standard Edition" and adds Spectrum Protect Snapshot to take application-aware snapshots, and the Storage Analytics Engine to optimize data placement.
IBM Spectrum Control Storage Insights -- A "Software-as-a-Service" subset of "Advanced Edition" for IBM storage products.
Implementation of Incremental Forever Backup and Deduplication with Spectrum Protect
This was combination of an overview of IBM Spectrum Protect plus an update of the latest v7.1.5 release. For those who use alternative backup software like Veritas NetBackup or Commvault Simpana, I explained how to implement "Incremental Forever" backup, which has been shown repeatedly by analysts and studies as being far more efficient than traditional backup methods like Full+Incremental or Full+Differential.
For those who may be using an earlier version of IBM Tivoli Storage Manager, I presented the new "Dedupe 2.0" features, including the new concept of "Container Pools" that can either be "Directory Pools" on SAN or NAS-based disk storage, or "Cloud Pools" on object storage, like IBM Cleversafe or IBM SoftLayer.
Spectrum Control Storage Insights - Redefining storage management simplicity
Mike Griese presented the newest member of the IBM Spectrum Control. Storage Insights is a Software-as-a-Service offering, that was recently reduced in price: only $250 per month for the first 50TB. Increasing amounts of storage capacity monitored are tiered at lower and lower prices.
Real-time Compression in Database environment
When it comes to compression, should you compress at the database level, or in the storage device? Database management systems like IBM DB2 and Oracle DB offer row-level or page-level compression.
IBM Real-time Compression available in IBM XIV and all of the latest Spectrum Virtualize products: SAN Volume Controller, Storwize V7000, Storwize V7000 Unified, Storwize V5000, FlashSystem V9000, as well as any of these in the VersaStack converged system from IBM and Cisco.
IBM ran tests that compared volume with database uncompressed, database-based compression, compression on IBM Storwize V7000 with IBM Real-time Compression, and a test run that does both database and storage-based compression together. The results might surprise you!
I explained the pros and cons of each method of compression, and why you might choose one or the other.
Be Ready for Object Storage with CleverSafe
Eric Forestier (IBM Montpelier) presented a quick overview of IBM Cleversafe, then did a live demo of the PUT and GET features. For example, he used the Linux CURL command to upload a video file as an object in his IBM Cleversafe cluster back in France. Then he used a regular browser to stream the video back.
Was Dubai too far away for you to attend? Want to hear the latest technical information about IBM Storage, but not willing to wait until the big [IBM Edge Conference] this September? We will have several more "IBM TechU Comes to You" events in May and June.
This week, I presented at the "IBM TechU Comes to You" event in beautiful Dubai, United Arab Emirates. This was a three-day event, so here is my recap of Day 2.
Introducing the Spectrum Storage Suite
Mike Griese (IBM WW Spectrum Storage Software Evangelist) presented an overview of the IBM Spectrum Storage family of products, and the new IBM Spectrum Storage Suite license which drastically simplifies the TB-licensing of all six products into a single number.
Spectrum Scale - introduction, use cases, competitive advantages
I presented an overview of IBM Spectrum Scale v4.2.1 release. I covered our support for POSIX, NFS, SMB, Hadoop, OpenStack Swift and Amazon S3 interfaces.
IBM Spectrum Scale is an ideal solution to replace NetApp filers, EMC Isilon or DataDomain storage devices. Use cases include clustered NAS, Object store, and Hadoop repository for analytics.
IBM Spectrum Archive -- Integration with Spectrum Scale, and its Applications in CCTV and Media
This was another special request from the UAE team, and I had a lot of fun putting it together. I started talking about IBM's recent acquisitions in video technologies, including LiveStream and ClearLeap.
I then explained how Spectrum Scale works, and how Spectrum Archive works either separately, or in combination with Spectrum Scale.
A live demo was planned to show this all off, but sadly I had network, firewall and/or VPN issues that prevented me from attaching to my Tucson-based systems. I then wrapped up with client references that have successfully used IBM Spectrum Archive in this area.
IBM Virtual Storage Center - Prepare your existing storage for the future
Mike Griese presented IBM Virtual Storage Center, which combines the "Control Plane" product of IBM Spectrum Control Advanced Edition, with the "Data Plane" products under IBM Spectrum Virtualize.
Introduction to Object Storage and its Applications - Cleversafe
I presented the basics of object store, a radical new way of storing information and how it is different from block or file-based storage alternatives.
I then covered the features of IBM Cleversafe solutions, available as software, pre-built appliances, and in the Cloud. I wrapped up with practical use cases for Content Repository, Enterprise Collaboration, Active Archive, Storage as a Service, and Backup storage pool.
Integration between IBM Spectrum Scale and Cleversafe
This was a fun session.
I presented an overview of IBM Spectrum Scale which provides volume, file and object-level storage interfaces on data that can span various flash, hybrid and spinning disk storage devices.
I gave a quick recap of Cleversafe for those who missed my earlier session.
I then showed how files can be migrated from IBM Spectrum Scale to either Cleversafe on-premises, Cleversafe in the Cloud on IBM SoftLayer, or LTFS-enabled tape using Spectrum Archive, or to any combination of disk, tape, object storage, Cleversafe and Cloud through IBM Spectrum Protect HSM and Space Management features.
Tuesday evening I went out to dinner with the z Systems team. Earlier in my career, I was the chief architect of DFSMS, the storage management element of z/OS operating system, so I continue to have close ties with the folks from Poughkeepsie.
Was Dubai too far away for you to attend? Want to hear the latest technical information about IBM Storage, but not willing to wait until the big [IBM Edge Conference] this September? We will have several more "IBM TechU Comes to You" events in May and June.
This week, I presented at the "IBM TechU Comes to You" event in the beautiful [Kempinski hotel], part of the [Mall of the Emirates] on the famous Sheikh Zayed Road in Dubai, United Arab Emirates. This was a three-day event, so here is my recap of Day 1.
Marlin Maddy (IBM Systems Lab Services) acted as emcee to kick off this event. We had about 150 attendees. Louise Hemond-Wilson (IBM Distinguished Engineer) and Glenn Anderson (IBM Systems Lab services) presented similar to last week in Atlanta. See my blog post [Atlanta Day 1 Recap] for an overview.
Software Defined Storage - What is it, How can it help?
Mike Griese (IBM WW Spectrum Storage Software Evangelist) presented his viewpoint on Software Defined Storage. His focus was on what we call "software-based" or "software-deployed" storage solutions. These are solutions that are basically software deployed on industry-standard servers, such as x86 or OpenPower, that provide a choice of server vendor.
(In Atlanta, Clod Barrera, Jeff Barnett, and I presented back-to-back sessions on Software Defined Storage (SDS). See my blog post [Atlanta Day 1 Recap] for an overview of those three sessions.)
The key difference between "Software-Deployed" storage and "Software-Controlled" storage is that the former is ideal to reduce costs by using commodity, off-the-shelf servers, but may not have all of the OpenStack, VMware or Microsoft APIs needed to effectively manage the solution as part of a large data center or Cloud facility.
If, however, you are deploying Software-deployed storage in Remote Office/Branch Office locations, Test/Dev departments, or similar small deployments, that may not be an issue.
All Flash is not Equal -- Contrasting difference between IBM FlashSystem and SSD
This was a special request by the local UAE team, because many FlashSystem presentations focus on the product, but don't explain the underlying technology, specifically what differentiates IBM FlashSystem from substantially slower competitive alternatives like EMC XtremIO and PureStorage that are based instead on fallible commodity Solid State Drives (SSD).
By working closely with our chip vendor, Micron, IBM was able to improve the write endurance of these Multi-level cell (MLC) chips by 9.4x, and reduce write amplification by 45 percent.
I explained IBM's clever asymmetrical wear-level balancing, heat segregation, read disturb mitigation, voltage level shifting, and health binning, all of which contribute to the performance and reliability of this solution. IBM's innovative Error Correcting Code provides LDPC-like correction strength but at much faster BCH-like latency speed.
This was such a popular session that I have been asked to present again at the upcoming IBM TechU events in San Francisco, Chicago and Boston.
How to combine advantage of storage virtualization & Flash performance (Turbocompression effect)
Dominique Salomon (IBM Certified IT Specialist Storage from Montpelier, France) presented Turbocompression, the benefits of combining IBM Real-time Compression (RtC) with Easy Tier sub-volume automated tiering.
Sometimes two things just go well together. Chocolate and Peanut Butter, Bacon and Maple Syrup, Peaches and Cream, are just a few pairings that come to mind.
Initially, when IBM introduced RtC, it did not allow Easy Tier on the same compressed volumes, in an effort to avoid conflicts. Then in a later release, IBM lifted the restriction, allowing them to apply to the same volumes. The results were surprising, both benefit each other. IBM has taken this further, using Easy Tier information to enhance compression algorithms on an extent by extent basis.
The combination improves performance while reducing total cost of ownership, and is available on all of the latest Spectrum Virtualize products: SAN Volume Controller, Storwize V7000, Storwize V7000 Unified, Storwize V5000, FlashSystem V9000, as well as any of these in the VersaStack converged system from IBM and Cisco.
DS8880 IBM Newest Disk Storage System
Maurice "Mo" McCullough (IBM Lab Services and Training) presented the latest DS8000 models, the DS8884 and DS8886. IBM is number #1 in storage attached to the mainframe, with 42 percent marketshare, and this is because IBM's investment in this platform, beating out HDS, EMC and HPE.
Each country and culture is different, but in many of the Islamic countries, it is considered inappropriate to serve alcoholic drinks at the after-hours reception. Instead, we had our sponsors serve juice and coffee. IBM does business in over 170 countries, and I have been to nearly half of them, so we know how to adjust and adapt to each and every unique situation.

Last week, I was in Atlanta for the "IBM TechU Comes to You" event at the beautiful Marriott Marquis hotel. This was a three-day event, so here is my recap of Day 3.
Troubleshooting SAN Performance Issues
Jim Blue (IBM SAN Central) did a great job presenting best practices for resolving performance issues in your Storage Area Network (SAN). This was an advanced technical session intended for SAN administrators, with more level of detail than I am used to.
IBM's Cloud Storage Options
What do all IBM Storage products have in common? They can all be used in Cloud deployments. All of them. Really! No exceptions. I did a short 20-minute version of this in Las Vegas last February for InterConnect conference. Here in Atlanta, I expanded this to a full hour version.
(Whenever IBM Storage is sold into a Cloud deployment, IBM counts this as "IBM Cloud revenue" instead of "IBM Systems Storage revenue". Total IBM Cloud revenues (public,private and hybrid) for the first quarter of 2016 increased 34 percent--up 36 percent adjusting for currency--thanks to this clever way of counting money. See the [IBM 1Q 2016 Results] for more details.)
When I was first asked to cover "Cloud Storage", I asked "What do YOU mean by Cloud Storage?" as different people have different notions of what that is. Their response "You tell US what Cloud Storage is!" So, I came up with a four category taxonomy, and for each category, I explain which protocols of block, file or object provide the best fit, and which IBM Storage products we lead with in each area.
Optimizing Performance with IBM Spectrum Virtualize
IBM Spectrum Virtualize is the software that runs on IBM SAN Volume Controllers, Storwize, FlashSystem V9000, and all of these can be part of a VersaStack solution from IBM and Cisco. John Wilkinson from the IBM Hursley Lab that develops the IBM Spectrum Virtualize software gave a great presentation on how to optimize performance with these offerings.
A good part of his session was discussing the new "Distributed RAID" feature. Rather than having a dedicated SPARE drive that becomes a bottleneck during a RAID rebuild, the spare drive space is interspersed and rotated among all the drives, so that rebuilds can occur in parallel, much like the distributed RAID-10 in the IBM XIV storage system.
Using IBM Spectrum Control to manage IBM Spectrum Scale
Brian Sherman presented the latest synergy between Spectrum Control and Spectrum Scale, two products in our IBM Spectrum Storage family. In past releases, Spectrum Control was focused almost exclusively on SAN-based storage, with some support for IBM N series and NetApp filers. Now, IBM Spectrum Control provides a range of features to help manage IBM Spectrum Scale deployments, both at the file and object level.
At the end of the last day of this conference, people left early. Atlanta traffic is worse than Los Angeles or Boston. Rather than fly back home to Tucson, only to fly out again to Dubai, I stayed in Atlanta to fly directly to Dubai for my next speaking gig.
