Jim is an IBM Fellow for IBM Systems and Technology Group. There are only 73 IBM Fellows currently working for IBM, and this is the highest honor IBM can bestow on an employee. He has been working with IBM since 1968.
He is tasked with predicting the future of IT, and help drive strategic direction for IBM. Cost pressures, requirements for growth, accelerating innovation and changing business needs help influence this direction.
IBM's approach is to integrate four different "IT building blocks":
Scale-up Systems, like the IBM System Storage DS8000 and TS3500 Tape Library
Resource Pools, such as IBM Storage Pools formed from managed disks by IBM SAN Volume Controller (SVC)
Integrated stacks and appliances, integrated software and hardware stacks, from Storwize V7000 to full rack systems like IBM Smart Analytics Server or CloudBurst.
Mobility of workloads and resources requires unified end-to-end service management. Fortunately, IBM is the #1 leader in IT Service Management solutions.
Jim addressed three myths:
Myth 1: IT Infrastructures will be homogenous.
Jim feels that innovations are happening too rapidly for this to ever happen, and is not a desirable end-goal. Instead, a focus to find the right balance of the IT building blocks might be a better approach.
Myth 2: All of your problems can be solved by replacing everything with product X.
Jim feels that the days of "rip-and-replace" are fading away. As IBM Executive Steve Mills said, "It isn't about the next new thing, but how well new things integrate with established applications and processes."
Myth 3: All IT will move to the Cloud model.
Jim feels a substantial portion of IT will move to the Cloud, but not all of it. There will always be exceptions where the old traditional ways of doing things might be appropriate. Clouds are just one of the many building blocks to choose from.
Jim's focus lately has been finding new ways to take advantage of virtualization concepts. Server, storage and network virtualization are helping address these challenges through four key methods:
Sharing - virtualization that allows a single resource to be used by multiple users. For example, hypervisors allow several guest VM operating systems share common hardware on a single physical server.
Aggregation - virtualization that allows multiple resources to be managed as a single pool. For example, SAN Volume Controller can virtualize the storage of multiple disk arrays and create a single storage pool.
Emulation - virtualization that allows one set of resources to look and feel like a different set of resources. Some hypervisors can emulate different kinds of CPU processors, for example.
Insulation - virtualization that hides the complexity from the end-user application or other higher levels of infrastructure, making it easier to make changes of the underlying managed resources. For example, both SONAS and SAN Volume Controller allow disk capacity to be removed and replaced without disruption to the application.
In today's economy, IT transformation costs must be low enough to yield near-term benefits. The long-term benefits are real, but near-term benefits are needed for projects to get started.
What set's IBM ahead of the pack? Here was Jim's list:
100 Years of Innovation, including being the U.S. Patent leader for the last 18 years in a row
IBM's huge investment in IBM Research, with labs all over the globe
Leadership products in a broad portfolio
Workload-optimized designs with integration from middleware all the way down to underlying hardware
Comprehensive management software for IBM and non-IBM equipment
Clod is an IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage. His presentation focused on trends and directions in the IT storage industry. Clod started with five workload categories:
To address these unique workload categories, IBM will offer workload-optimized systems. The four drivers on the design for these are performance, efficiency, scalability, and integration. For example, to address performance, companies can adopt Solid-State Drives (SSD). Unfortunately, these are 20 times more expensive dollar-per-GB than spinning disk, and the complexity involved in deciding what data to place on SSD was daunting. IBM solved this with an elegant solution called IBM System Storage Easy Tier, which provides automated data tiering for IBM DS8000, SAN Volume Controller (SVC) and Storwize V7000.
For scalability, IBM has adopted Scale-Out architectures, as seen in the XIV, SVC, and SONAS. SONAS is based on the highly scalable IBM General Parallel File System (GPFS). File systems are like wine, they get better with age. GPFS was introduced 15 years ago, and is more mature than many of the other "scalable file systems" from our competition.
Areal Density advancements on Hard Disk Drives (HDD) are slowing down. During the 1990s, the IT industry enjoyed 60 to 100 percent annual improvement in areal density (bits per square inch). In the 2000s, this dropped to 25 to 40 percent, as engineers are starting to hit various physical limitations.
Storage Efficiency features like compression have been around for a while, but are being deployed in new ways. For example, IBM invented WAN compression needed for Mainframe HASP. WAN compression became industry standard. Then IBM introduced compression on tape, and now compression on tape is an industry standard. ProtecTIER and Information Archive are able to combine compression with data deduplication to store backups and archive copies. Lastly, IBM now offers compression on primary data, through the IBM Real-Time Compression appliance.
For the rest of this decade, IBM predicts that tape will continue to enjoy (at least) 10 times lower dollar-per-GB than the least expensive spinning disk. Disk and Tape share common technologies, so all of the R&D investment for these products apply to both types of storage media.
For integration, IBM is leading the effort to help companies converge their SAN and LAN networks. By 2015, Clod predicts that there will be more FCoE purchased than FCP. IBM is also driving integration between hypervisors and storage virtualization. For example, IBM already supports VMware API for Array Integration (VAAI) in various storage products, including XIV, SVC and Storwize V7000.
Lastly, Clod could not finish a presentation without mentioning Cloud Computing. Cloud storage is expected to grow 32 percent CAGR from year 2010 to 2015. Roughly 10 percent of all servers and storage will be in some type of cloud by 2015.
As is often the case, I am torn between getting short posts out in a timely manner versus spending some more time to improve the length and quality of information, but posted much later. I will spread out the blog posts in consumable amounts throughout the next week or two, to achieve this balance.
This post concludes my series of posts on Oracle OpenWorld 2011 conference. Here are some pictures from Wednesday and Thursday.
IBM as the yardstick by which everyone measures against
Our friends at Violin Memory systems mentioned our joint-venture success results with IBM GPFS, scanning 10 billion files in less than an hour. (Their booth must have been slow, because members of their team spent a lot of time in our IBM booth!)
In fact, it seemed every company compared themselves to IBM in one fashion or another. Larry said that "IBM is a great company" and mentioned the IBM systems several times in comparisons to Oracle's newly announced hardware offerings.
Larry's Sailing Vessel
When things slowed down, I took a walk to see the other parts of the exhibition area. In the Moscone West building was Larry's catamaran that won [last year's America's Cup].
I used to sail myself, and have been part of crews in sailing races in both Japan and Australia. A few years ago, I watched the America's Cup time trials in New Zealand.
On the Streets of San Francisco
On the streets, IBM had advertised some of its products in a manner that thousands of attendees would see every day. Here we have some factoids related to IBM Netezza and DB2 database on POWER servers. We were very careful not to mention either product in the IBM Booth itself, as we all understand that IBM is a guest in Oracle's house this week. We certainly don't want to do anything to upset Larry in any way to make him treat IBM like he treated HP last year, or Salesforce.com this year.
Rest in Peace, Steve Jobs, 1955-2011
On Wednesday evening at Oracle OpenWorld, we were tearing down the booth when we heard that Apple co-founder Steve Jobs had passed away. This is truly a loss for the entire IT industry. I never met Steve in person, nor have I been to any Apple conferences like MacWorld that he spoke at.
At various keynote sessions, Larry Ellison compared his Oracle products to those of Apple, Inc., suggesting that Oracle is the "Apple for the Enterprise".
On our way back to the Hilton hotel on O'Farrell, there was a candle vigil at the Apple Store near Union Square. People left sticky notes on the glass window.
There were a lot of tributes to Steve Jobs, but I liked this 15-minute video of his 2005 Commencement Speech at Stanford University titled [How to Live before you Die.
This will be one of those moments where years later, many people will remember exactly where they were, and what they were doing, when they heard the news. For many, that news came as tweets or text messages on the very iPhones and iPads he helped design.
Rock Concert - Wednesday night
On Wednesday evening, I joined thousands of other attendees on Treasure Island to hear and watch Sting, Tom Petty and the Heartbreakers, and the English Beat in concert. It was cold and dark, but we all had a good time. Needless to say, I didn't make it to Marc Benioff's 8:00am Thursday morning session!
A word of advice: If you go to an evening rock concert at Treasure Island, dress warmly!
Despite the sad news about Steve Jobs, I had a great time at this conference. I learned a lot about what other IT vendors are doing, talked to dozens of IBM clients at the booth, and got to make some new friends that work in other parts of IBM.
(FTC Disclosure: I work for IBM. IBM and Apple are technology partners. I proudly own an Apple iPod, several Mac Mini computers and shares of stock in both IBM and Apple, Inc.)
Continuing my coverage of the 30th annual [Data Center Conference]. here is a recap of Wednesday breakout sessions.
Aging Data: The Challenges of Long-Term Data Retention
The analyst defined "aging data" to be any data that is older than 90 days. A quick poll of the audience showed the what type of data was the biggest challenge:
In addition to aging data, the analyst used the term "vintage" to refer to aging data that you might actually need in the future, and "digital waste" being data you have no use for. She also defined "orphaned" data as data that has been archived but not actively owned or managed by anyone.
You need policies for retention, deletion, legal hold, and access. Most people forget to include access policies. How are people dealing with data and retention policies? Here were the poll results:
The analyst predicts that half of all applications running today will be retired by 2020. Tools like "IBM InfoSphere Optim" can help with application retirement by preserving both the data and metadata needed to make sense of the information after the application is no longer available. App retirement has a strong ROI.
Another problem is that there is data growth in unstructured data, but nobody is given the responsibility of "archivist" for this data, so it goes un-managed and becomes a "dumping ground". Long-term retention involves hardware, software and process working together. The reason that purpose-built archive hardware (such as IBM's Information Archive or EMC's Centera) was that companies failed to get the appropriate software and process to complete the solution.
Cloud computing will help. The analyst estimates that 40 percent of new email deployments will be done in the cloud, such as IBM LotusLive, Google Apps, and Microsoft Online365. This offloads the archive requirement to the public cloud provider.
A case study is University of Minnesota Supercomputing Institute that has three tiers for their storage: 136TB of fast storage for scratch space, 600TB of slower disk for project space, and 640 TB of tape for long-term retention.
What are people using today to hold their long-term retention data? Here were the poll results:
Bottom line is that retention of aging data is a business problem, techology problem, economic problem and 100-year problem.
A Case Study for Deploying a Unified 10G Ethernet Network
Brian Johnson from Intel presented the latest developments on 10Gb Ethernet. Case studies from Yahoo and NASA, both members of the [Open Data Center Alliance] found that upgrading from 1Gb to 10Gb Ethernet was more than just an improvement in speed. Other benefits include:
45 percent reduction in energy costs for Ethernet switching gear
80 percent fewer cables
15 percent lower costs
doubled bandwidth per server
Ruiping Sun, from Yahoo, found that 10Gb FCoE achieved 920 MB/sec, which was 15 percent faster than the 8Gb FCP they were using before.
IBM, Dell and other Intel-based servers support Single Root I/O Virtualization, or SR-IOV for short. NASA found that cloud-based HPC is feasible with SR-IOV. Using IBM General Parallel File System (GPFS) and 10Gb Ethernet were able to replace a previous environment based on 20 Gbps DDR Infiniband.
While some companies are still arguing over whether to implement a private cloud, an archive retention policy, or 10Gb Ethernet, other companies have shown great success moving forward!
This week I am in Moscow, Russia for today's "Edge Comes to You" event. Although we had over 20 countries represented at the Edge2012 conference in Orlando, Florida earlier this month, IBM realizes that not everyone can travel to the United States. So, IBM has created the "Edge Comes to You" events where a condensed subset of the agenda is presented. Over the next four months, these events are planned in about two dozen other countries.
This is my first time in Russia, and the weather was very nice. With over 11 million people, Moscow is the 6th largest city in the world, and boasts having the largest community of billionaires. With this trip, I have now been to all five of the so-called BRICK countries (Brazil, Russia, India, China and Korea) in the past five years!
The venue was the [Info Space Transtvo Conference Center] not far from the Kremlin. While Barack Obama was making friends with Vladimir Putin this week at the G2012 Summit in Mexico, I was making friends with the lovely ladies at the check-in counter.
If it looks like some of the letters are backwards, that is not an illusion. The Russian language uses the [Cyrillic alphabet]. The backwards N ("И"), backwards R ("Я"), the number 3 ("З), and what looks like the big blue staple logo from Netapp ("П"), are actually all characters in this alphabet.
Having spent eight years in a fraternity during college, I found these not much different from the Greek alphabet. Once you learn how to pronounce each of the 33 characters, you can get by quite nicely in Moscow. I successfully navigated my way through Moscow's famous subway system, and ordered food on restaurant menus.
The conference coordinators were Tatiana Eltekova (left) and Natalia Grebenshchikova (right). Business is booming in Russia, and IBM just opened ten new branch offices throughout the country this month. So these two ladies in the marketing department have been quite busy lately.
I especially liked all the attention to detail. For example, the signage was crisp and clean, and the graphics all matched the Powerpoint charts of each presentation.
Moscow is close to the North pole, similar in latitude as Juneau, Alaska; Edinburgh, Scottland; Copenhagen, Denmark; and Stockholm, Sweden.
As a result, it is daylight for nearly 18 hours a day. The first part of the day, from 8:00am to 4:30pm, was "Technical Edge", a condensed version of the 4.5 day event in Orlando, Florida. I gave three of the five keynote presentations:
Game Change on a Smarter Planet: A New Era in IT, discussing Smarter Computing and Expert-Integrated systems, based on what Rod Adkins presented in Orlando.
A New Approach to Storage, explaining IBM Smarter Storage for Smarter Computing, IBM's new approach to the way storage is designed and deployed for our clients
IBM Watson: How it Works and What it Means for Society Beyond Winning Jeopardy! explaining how IBM Watson technologies are being used in Healthcare and Financial Services, based on what I presented in Orlando.
(Note: I do not speak Russian fluently enough to give a technical presentation, so I did then entire presentation in English, and had real-time translators convert to Russian for me. The audience wore headphones. However, I was able to sprinkly a few Russian phrases, such as "доброе утро", "Я не понимаю по-русский" and "спасибо".)
After the keynote sessions, I was interviewed by a journalist for [Storage News] magazine. The questions covered a variety of topics, from the implications of [Big Data analytics] to the future of storage devices that employ [Phase Change Memory]. I look forward to reading the article when it gets published!
The afternoon had break-out sessions in three separate rooms. Each room hosted seven topics, giving the attendees plenty to choose from for each time slot. I presented one of these break-out sessions, Big Data Cloud Storage Technology Comparison. The title was already printed in all the agendas, so we went with it, but I would have rather called it "Big Data Storage Options". In this session, I explained Hadoop, InfoSphere BigInsights, internal and external storage options.
I spent some time comparing Hadoop File System (HDFS) with IBM's own General Parallel File System (GPFS) which now offers Hadoop interfaces in a Shared-Nothing Cluster (SNC) configuration. IBM GPFS is about twice as fast as HDFS for typical workloads.
At the end of the Technical Edge event, there was a prize draw. Business cards were drawn at random, and three lucky attendees won a complete four-volume set of my book series "Inside System Storage"! Sadly, these got held up in customs, so we provided a "certificate" to redeem them for the books when they arrive to the IBM office.
The second part of the day, from 5:00pm to 8pm, was "Executive Edge", a condensed version of the 2 day event in Orlando, designed for CIOs and IT leaders. Having this event in the evening allowed busy executives to come over after they spend the day in the office. I presented IBM Storage Strategy in the Smarter Computing Era, similar to my presentation in Orlando.
Both events were well-attended. Despite fighting jet lag across 11 time zones, I managed to hang in there for the entire day. I got great feedback and comments from the attendees. I look forward to hearing how the other "Edge Comes to You" events fare in the other countries. I would like to thank Tatiana and Natalia for their excellent work organizing and running this event!
By combining multiple components into a single "integrated system", IBM can offer a blended disk-and-tape storage solutions. This provides the best of both worlds, high speed access using disk, while providing lower costs and more energy efficiency with tape. According to a study by the Clipper Group, tape can be 23 times less expensive than disk over a 5 year total cost of ownership (TCO).
I've also covered Hierarchical Storage Management, such as my post [Seven Tiers of Storage at ABN Amro], and my role as lead architect for DFSMS on z/OS in general, and DFSMShsm in particular.
However, some explanation might be warranted in the use of these two terms in regards to SONAS. In this case, ILM refers to policy-based file placement, movement and expiration on internal disk pools. This is actually a GPFS feature that has existed for some time, and was tested to work in this new configuration. Files can be individually placed on either SAS (15K RPM) or SATA (7200 RPM) drives. Policies can be written to move them from SAS to SATA based on size, age and days non-referenced.
HSM is also a form of ILM, in that it moves data from SONAS disk to external storage pools managed by IBM Tivoli Storage Manager. A small stub is left behind in the GPFS file system indicating the file has been "migrated". Any reference to read or update this file will cause the file to be "recalled" back from TSM to SONAS for processing. The external storage pools can be disk, tape or any other media supported by TSM. Some estimate that as much as 60 to 80 percent of files on NAS have low reference and should be stored on tape instead of disk, and now SONAS with HSM makes that possible.
This distinction allows the ILM movement to be done internally, within GPFS, and the HSM movement to be done externally, via TSM. Both ILM and HSM movement take advantage of the GPFS high-speed policy engine, which can process 10 million files per node, run in parallel across all interface nodes. Note that TSM is not required for ILM movement. In effect, SONAS brings the policy-based management features of DFSMS for z/OS mainframe to all the rest of the operating systems that access SONAS.
HTTP and NIS support
In addition to NFS v2, NFS v3, and CIFS, the SONAS v1.1.1 adds the HTTP protocol. Over time, IBM plans to add more protocols in subsequent releases. Let me know which protocols you are interested in, so I can pass that along to the architects designing future releases!
SONAS v1.1.1 also adds support for Network Information Service (NIS), a client/server based model for user administration. In SONAS, NIS is used for netgroup and ID mapping only. Authentication is done via Active Directory, LDAP or Samba PDC.
SONAS already had synchronous replication, which was limited in distance. Now, SONAS v1.1.1 provides asynchronous replication, using rsync, at the file level. This is done over Wide Area Network (WAN) across to any other SONAS at any distance.
Interface modules can now be configured with either 64GB or 128GB of cache. Storage now supports both 450GB and 600GB SAS (15K RPM) and both 1TB and 2TB SATA (7200 RPM) drives. However, at this time, an entire 60-drive drawer must be either all one type of SAS or all one type of SATA. I have been pushing the architects to allow each 10-pack RAID rank to be independently selectable. For now, a storage pod can have 240 drives, 60 drives of each type of disk, to provide four different tiers of storage. You can have up to 30 storage pods per SONAS, for a total of 7200 drives.
An alternative to internal drawers of disk is a new "Gateway" iRPQ that allows the two storage nodes of a SONAS storage pod to connect via Fibre Channel to one or two XIV disk systems. You cannot mix and match, a storage pod is either all internal disk, or all external XIV. A SONAS gateway combined with external XIV is referred to as a "Smart Business Storage Cloud" (SBSC), which can be configured off premises and managed by third-party personnel so your IT staff can focus on other things.
See the Announcement Letters for the SONAS [hardware] and [software] for more details.
For those who are wondering how this positions against IBM's other NAS solution, the IBM System Storage N series, the rule of thumb is simple. If your capacity needs can be satisfied with a single N series box per location, use that. If not, consider SONAS instead. For those with non-IBM NAS filers that realize now that SONAS is a better approach, IBM offers migration services.
Both the Information Archive and the SONAS can be accessed from z/OS or Linux on System z mainframe, from "IBM i", AIX and Linux on POWER systems, all x86-based operating systems that run on System x servers, as well as any non-IBM server that has a supported NAS client.
