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

While HDS blogger Hu Yoshida and IBM blogger Barry Whyte make a [great case for why you should buy IBM SAN Volume Controller], my favorite arch-nemesis and fellow blogger BarryB on his Storage Anarchist blog feels the SVC is "blue spray paint".
BarryB's latest round of red-meat rhetoric is his amusing post [This is like déjà vu all over again], titled after a [quote from Yogi Berra].BarryB pokes fun at Andy Monshaw's commentsin Chris Preimesberger's eWeek article [IBM's Big Storage Picture], andmy post ealier this week about Sun's "Open Storage" initiative [Simply Dinners and Open Storage from Sun], as if the two were somehow connected.
He feels I was unfair to accuse EMC of "proprietary interfaces" without spelling out what I was referring to. Here arejust two, along with the whines we hear from customers that relate to them.
Certainly BarryB is correct that IBM still has a few remaining "proprietary" items of its own. IBM has been in business over 80 years, but it was only the last 10-15 years that IBM made a strategic shift away from proprietary and over to open standards and interfaces. The transformation to "openness" is not yet complete, but we have made great progress. Take these examples:
So for those out there who thought that my comment about EMC's proprietary interfaces in any way implied thatIBM did not have any of its own, the proverbial ["pot calling the kettle black"] so to speak, I apologize.
BarryB shows off his [PhotoShop skills] with the graphic below. I take it as a compliment to be compared to anAll-American icon of business success.
The anti-trust lawsuit that BarryB mentions happened in 1969, which forced IBM to separate some of the software from its hardware offerings, and prevented IBM from making various acquisitions for years to follow, forcing IBM instead into technology partnerships. I'm glad that's all behind us now!

Continuing my business trip through Asia, I have left Chengdu, China, and am now in Kuala Lumpur, Malaysia.
On Sunday, a colleague and I went to the famous Petronas Twin Towers, which a few years ago were officially the tallestbuildings in the world. If you get there early enough in the day, and wait in line for a few hours, you can get a ticket permitting you to go up to the "Skybridge" on the 41st floor that connects the two buildings. The views are stunning, and I am glad to have done this.(If you are afraid of heights, get cured by facing your fears with skydiving)
You would think that a question as simple as "Which is the tallest building in the world?" could easily be answered, given that buildings remain fixed in one place and do not drastically shrink or get taller over time or weather conditions, and the unit of height, the "meter", is an officially accepted standard in all countries, defined as the distance traveled by light in absolute vacuum in 1/299,792,458 of a second.
The controversy stems around two key areas of dispute:
To bring some sanity to these comparisons, the Council on Tall Buildings and Urban Habitat has tried to standardize the terms and definitions to makecomparisons between buildings fair. Why does all this matter whose building is tallest? It matters in twoways:
What does any of this have to do with storage? Two weeks ago, IBM and the Storage Performance Councilanswered the question "Which is the fastest disk system?" with apress release. Customers thatcare about performance of their most mission critical applications are often willing to pay a premium to run theirapplications on the fastest disk system, and the IBM System Storage SAN Volume Controller, built through aglobal collaboration of architects and engineers across several countries, is (in my opinion at least) an impressive feat of storage engineering.
EMC bloggerChuck Hollis was the first to question the relevance of these results, and I failed to "turn the other cheek" and responded accordingly. The blogosphere erupted, with more opinions piled on by others, many from EMC andIBM, found in comments on these posts or other blogs, some have since been retracted or deleted, while othersremain for historical purposes.
At the heart of all this opinionated debate, lies a few areas of exploration:
I will try to address some of these issues in a series of posts this week.

Happy New Year, everyone!
I hope everyone had some time these past few weeks of the Winter Solstice to enjoy some time off with friends and family. I had a great trip to New York City, got to visit my brother and his friends, went to see my friends in Michigan to celebrate New Years Eve, and see the world premiere of [LexiBaby], an independent film from fellow filmmaker Jonathan Petro.
Talking to people in New York, Michigan and Arizona gave me some perspective on what 2008 was like for them, and what they anticipate for the new 2009 year. Borrowing the meme from last month's Freakonomics contest[Got Six Words to Inspire America] and the book[Not Quite What I Was Planning: Six-Word Memoirs by Writers Famous and Obscure], I can summarize the responses I heard into three groups:
The latter of course from fellow IBMers, corporate executives receiving bailout money, attorneys that specialize in foreclosures, and the lucky few who will be in Washington DC for the US Presidential Inauguration.In addition to all the bailout money from banks, insurance companies and automakers that will be spent on IBM equipment and services, there might be additional funds from the US Government to improve our country's information infrastructure.In a recent Forbes article titled[The Tech Solution To The Recession], Andy Greenberg writes about US president-elect Barack Obama's ideas about a stimulus to the economy. Here's an excerpt:
"IBM, for starters, believes that a massive infusion of cash should go toward cutting-edge technology. Last month, IBM CEO Sam Palmisano presented a report to Obama's transition team from the Information Technology and Innovation Foundation (ITIF) that argues that a $30 billion investment in universal broadband, health information technology and a smarter power grid could create 950,000 jobs.
The concept and advantages of network multipliers are not new.

Last Tuesday, we had our official "Grand Opening" for the new Tucson Executive Briefing Center!
We sent out fancy invitations to all the IBM executives who supported this center, local dignitaries from the Tucson and State of Arizona level, and all of the IBM employees on the Tucson campus.
Since our new center is significantly cozier (5700 square feet versus our previous 15,000 square feet), we split the day into two separate events. The first for the IBM executives and local VIPs, and the second for the rest of the IBM employees on campus.
Of course, there is no free lunch. The day started out with a series of speeches. My manager, Doug Davies, was the master of ceremonies to introduce each speaker.
Alistair Symon, IBM Vice President of Enterprise Storage, explained how important storage affects everyone's lives. If you use an ATM machine to withdraw money, for example, you are most probably using IBM System Storage behind the scenes. Nearly all of the IBM disk and tape storage products are designed here in Tucson.
Bruce Wright (shown here) directs the University of Arizona's Office of University Research Parks, serves as CEO of the UA Tech Park, and the founder and president of the Arizona Center for Innovation. Bruce said a few words on how please he was that IBM decided to reverse its July 2011 decision to leave Tucson. The UofA owns all the property, renting back four of the eleven buildings back to IBM, so is effectively our landlord. Next year will mark the 20th anniversary of IBM's sale of the technology park to the University.
Tucson Councilwoman Shirley Scott talked about the improtance of high-paying jobs to the local economy. While IBMers in Tucson are paid less than our counterparts in San Jose, Austin, Raleigh or Poughkeepsie, we are certainly [paid more than the average Tucsonan], thus helping to raise the standard of living here.
Dr. Michael Varney, president and CEO of the local Tucson Metropolitan Chamber of Commerce, praised IBM for its strong reputation in ethics and diversity.
My new second-line manager, Karl Duvalsaint, and my new third-line manager, Doug Dreyer, emphasized the importance of co-locating Briefing Centers in sites that have Research and Development activity. It is important for clients to interact directly with developers, and it is also good for developers to understand directly from clients their needs, preferences and requirements. Worldwide, the IBM Systems and Technology Group has only twelve Executive Briefing Centers, and the Tucson EBC is one of them.
This is not to say that IBM does not have centers in other locations. Our newest client center in Singapore is a shining example. Of course, if they want experts to speak to clients there, they need to be flown in. Doug Dreyer mentioned that IBM plans to launch six such centers in Africa as well.
Next was the ribbon cutting. From left to right, Lee Olguin (our Gunny Sargeant), Tucson Councilwoman Shirley Scott, UofA's Bruce Wright, IBM VP of Program Management Calline Sanchez, My second-line manager Karl Duvalsaint, IBM VP Allistair Simon, my first-line manager Doug Davies, Tucson Chamber of Commerce President Dr. Michael Varney, and my third-line manager Doug Dreyer. We had a member of the local high school band do the drum roll.
Once the ribbon was cut, the IBM Executves and local VIPs were brought in to see the new facility, which has two large rooms, one common dining area, an 800-square foot green data center to showcase our products, our own set of restrooms, a galley to stage up the food and beverage service, and two smaller rooms for private conversations or conference calls. A local high school band provided live music throughout the day.

This week -- Jan 29 to Feb 2, 2018 -- I am in New York city with other IBM Storage executives, to meet with Channel distributors and Business Partners. If you are in the NYC area, and wish to have a product briefing, or just dinner or drinks, let me know!
IBM and Cisco announced the [ Cisco MDS 9132T 32G Fabric Switch for IBM Storage Networking], the next generation of Cisco MDS Series Fabric switches, combining high performance with outstanding flexibility and cost effectiveness.
I believe the "T" stands for "Third generation", as we have had other 9132 boxes before. Here are the details:
Why is this important? Because the 16 Gbps and 32 Gbps transceivers support NVMe over Fabrics. Let's do a quick NVMe recap:
Last May, IBM announced that its developers are re-tooling the end-to-end storage stack to support [New Faster Protocols for Flash Storage], to boost the experience of everyone consuming the massive amounts of data now being perpetuated across cloud services, retail, banking, travel and other industries.
NVMe is a new language protocol that is replacing traditional SAS and SATA standards for solid state drives (SSD). Through employing parallelism, to simultaneously process data across a network of devices, clients can anticipate significantly reduced delays caused by data bottlenecks and move higher volumes of data within their existing flash storage systems.
(For some basic background, Cisco's J Metz explains [NVMe for Absolute Beginners]. You can also ready the IBM Redbook [IBM Storage and the NVM Express Revolution] by Ioannis Koltsidas and Vincent Hsu.)
IBM's NVMe strategy is based on optimizing the entire storage system stack - from applications requiring the data to flash technology to store it. Through the development of its FlashSystem family of all-flash storage solutions, IBM recognized years ago that multiple technologies would be required to address the demands of ultra-low latency data processing. IBM is developing solutions with NVMe across its storage portfolio, which it plans to bring to market in 2018.
At the AI Summit New York, December 2017, IBM disclosed a [technology preview and demonstration] with the integration of IBM POWER9 Systems and IBM FlashSystem 900 using NVMe-over-Fabrics InfiniBand. This combination of technologies is ideally suited to run cognitive solutions such as IBM PowerAI Vision, which can ingest massive amounts of data while simultaneously completing real time inferencing (object detection).
Whether it is streams of data, transactional data, or batch processes, a consistent requirement is the lowest possible latency. Among the leading all flash storage vendors, IBM with its FlashSystem 900, has stuck to its mission delivering low latency all flash arrays. Along comes NVMe-oF, which is, at its core, about getting rid of latency.
How do you take an already low latency protocol, like InfiniBand or Fibre Channel, and make it faster? Replace SCSI with NVMe and enable NVMe from server to fabric to storage array.
The FlashSystem 900 has been shipping with InfiniBand using SRP (SCSI over RDMA) for many years. In the technology preview, the very same InfiniBand adapter, based on the Mellanox chip set, is instead used to support the OpenFabrics driver distribution and NVMe-oF InfiniBand.
While the demonstration last December used Infiniband, this is not the only transport. NVMe-OF can also be used with Ethernet, either using Internet Wide Area RDMA (iWARP) or RDMA over Converged Ethernet (RoCE). NVMe-OF over Fibre Channel is often referred to as FC-NVMe, and can drive NVMe over FCP or FCoE. Even though iWARP, RoCE and FCoE are all Ethernet-based, NVME-OF RDMA on the first two is different than FC-NVMe over FCoE.
Why not just drive NVMe commands over standard TCP/IP? The NVMe standards board is actually investigating this, but probably won't have anything until next year in 2019.
This week, IBM will be at the [Cisco Live!] event in Barcelona, Spain, talking about this new 9132T switch, as well as all of our VersaStack solutions! I won't be there, obviously, since I am in New York City, but if you are there, please send me photos! Barcelona is a wonderful city!

The hysterical nature of writing from EMC, and the calm responses from NetApp, speak volumes about the culturesof both companies.
The key point is that none of the "Non-erasable, Non-Rewriteable" (NENR) storage out there are certified as compliant by any government agency on the planet. Governments just aren't in the business of certifying such things. The best you can get is a third-party consultant, such as [Cohasset Associates], to help make decisions that are best for each particular situation.
In addition to SnapLock on N series, IBM offers the [IBM System Storage DR550], WORM tape and optical systems, all of which have been deemed compliant to the U.S. Securities and Exchange Commission [SEC 17a-4] federal regulations by Cohasset Associates. For medical patient records and images like X-rays, IBM offers the Grid Medical Archive Solution [GMAS]designed to meet the requirements of the U.S. Health Insurance Portability and Accountability Act[HIPAA].For other government or industry regulations, consult with your legal counsel.Read More]

Chris Anderson, of Wired magazine, wrote a great article called The Long Tail.
This article became a book by the same name published earlier this year, and I just discovered it on a recent visit to Second Life. A lot of IBMers are now alsoSecond Lifers, and I suspect it is just a matter of time before we are conductingour customer briefings there, and getting our year-end bonuses paid directly in Linden bucks.(Those of you not familiar with Second Life can watch this 3-minute video fromthe folks at Text100)
Anyways, the Long Tail describes the new economy of entertainment thanks to digitalstorage. Here are some of the key insights.
This has incredible implications for the storage industry. For one, content providers are going to dig deep into their archives to digitize and deliver "long tail" offerings. If they don't have a deep archive, many will start to build one. Second, the need to search through that large volume of content will become more critical. Classifying and indexing with the appropriate tags and metadata will be an important task.

While the rest of Americans were glued to their televisions watching President Obama explain his plan for recovery, my colleagues and Ihad dinner with clients from Canada.
Of course, in conversations with clients, it is best to avoid topics like politics or drugs,but the intersection of government health care and implications on IT can't be disregarded.Since Canada has a more efficient healthcare process, the government enjoys a lower costper citizen. President Obama has suggested that the United States should adopt reforms to make the American system more efficient, including electronic medical records.
Not surprisingly, [smarter healthcare] is part of IBM's latest set of strategic init If there is any situation that needs to deliver the right information, to the right people,at the right time, healthcare is certainly one of them. Having the right information canhelp reduce medical mistakes. I personally know some doctors here in Tucson, and they are the first to admit that theywould prefer to focus on their core strengths, which they spent many years in medical school,and leave the administrative details to someone else. Focusing on core strengths is acommon theme for successful businesses, and this is no different. Medical emergencies do not always happen near the hospital or clinic that your medical records are stored at.An exciting feature of digital information is that it is easy to transport to where it isneeded, unlike paper records or X-ray film.

Avi Bar-Zeeb of RealityPrime has an interesting post aboutHow Google Earth [really] Works.Normally, people who are very knowledgeable in a topic have a hard time describing concepts in basic terms. Avi was one of the co-founders of Keyhole, the company that built the predecessor for Google Earth, and also worked with Linden Lab for its 3D rendering it its virtual world, so he certainly knows what he is talking about. While he sometimes drops down into techno-talk about patents, the post overall is a good read.
It is perhaps human nature to be curious on how things are put together and how they function, leading to the popularity of web sites like www.
Many things can be used without understanding their internal inner workings. You can put on a pair of blue jeans without knowing how the cotton was made into denim fabric; lace up your favorite pair of running shoes without understanding the chemical make-up of the plastic that cushions your feet; or drink a glass of beer after your five mile run without knowing how alcohol is processed by your liver.
For technology, however, some people insist they need to know how it works in order for them to get the most use of it. When shopping for a car, for example, a guy might look under the hood, and ask questions about how the engine works, while his wife sits inside the vehicle, counting cup holders and making sure the radio has all the right buttons.
Not all technology suffers from need-to-know-itis. For example, the Apple iPod music player and the Canon PowerShot digital camera, are both just disk systems that read and write data, with knobs and dials on one end, and ports for connectivity on the other. Everyone just asks how to use their controls, and might read the manual to understand how to connect the cables. Few people who use these devices ask how they work before they buy them.
Other disk systems, the kind designed for data centers for the medium and large enterprise, apparently aren't there yet. Storage admins who might happily own both an iPod player and a PowerShot camera, insist they need to know how the technologies inside various storage offerings work. Is this just curiosity talking? Or are there some tasks like configuration, tuning, and support that just can't be done without this knowledge? Does knowing the inner workings somehow make the job more enjoyable, easier, or performed with less stress?
I'm curious what you think, send me a comment on this.

Back in October, Daryl Pereira asked me for an interview about my blog. I get a lot of these requests, but this one was different. Daryl is on the IBM DeveloperWorks team, and he was going to interview me to for the "Great Mind Challenge". This is a fun competition for a group of about 100 college students from San Jose State University to get them to learn blogging best practices and techniques.
The call was recorded and converted to a podcast, you can listen to it on the post titled [Insights from developerWorks top blogger Tony Pearson]. Here is the full chart deck:
During the interview, Daryl asked me about three blog posts in particular that got a significant number of hits.
In 2009 and 2010, I was the third most influential blogger on IBM's Developerworks, and now in 2011, I have risen to number one position! Internally, we call this "Winning the Devy" (like an Emmy, but for DeveloperWorks bloggers). I would like to thank all my readers for continuing to share in the conversation!
I am pleased with the turn-out we had attending last week for my Infoboom Webinar on [The Future of Storage]. The 55-minute replay is available on Infoboom, and the slide deck can be downloaded from the [IBM Expert Network].
I mentioned that I was going to Indianapolis and Boston next week to give lectures on this topic. Here are the details:
I will also be in San Francisco for Oracle OpenWorld (Oct 2-6), Auckland New Zealand (Nov 9-11), and Melbourne Australia (Nov 15-17).
It is funny how an article or blog post can remind me of something long, long ago.
Back in 2005, my manager, Rich Lechner, was then the Executive Advocate for a client in Chicago. While visiting that client, he asked what the client wanted most. His answer, for IBM to come in and do an "Information Lifecycle Management" (ILM) study on his IT environment. He agreed to send me on-site for a week.
I had done disk and tape studies of this kind before, but this time, I was going to do an end-to-end to evaluate their growth, and where was the best storage media for different data types.
Joining me were three "observers" from IBM Lab Services: Barbara Read, Steve Bisel and Tom Moore. As if I did not have enough pressure from the client, now I had to be "watched" while I interviewed the storage administrators, generated and reviewed reports.
At the end of the week, I had provide the client's upper management with a list of short-term, mid-term and long-term recommendations. As a side benefit, the client decided to purchase two DS8000 storage systems, replacing their HDS equipment!
After that initial engagement, the four of us formed a team. We performed similar studies at other client locations. Barbara Read was the process expert who wrote the "Documents of Understanding". Steve was our financial expert, and used spreadsheets to show total cost of ownership comparisons. Tom was our infrastructure expert, and used Microsoft Visio to document the inventory of IT equipment, and how it was all interconnected.
I was the consultant and public speaker for the team. I was able to incorporate the work of the three others into a Powerpoint presentation. During the week, we would show initial findings to the client, and then follow it up a few weeks later with a full report.
A lot has changed in the past 13 years! First, ILM was renamed to "Storage Infrastructure Optimization" (SIO) studies. Our initial team trained dozens of other practitioners. Today, SIO studies are done all over the world.
One of the original team members recently wrote a blog post on the latest on SIO. Please read Tom Moore's blog post [Corral your growing storage infrastructure!]
As you can imagine, I get a lot of email from around the world. This one, from a loyal reader from overseas, was particularly interesting. Normally, I would direct them to read the fantastic manual [RTFM], but decided instead to go ahead and tackle it here in my blog.
I will tackle this in three steps.
First, let's attach "Server 1" and the FlashSystem 900 to the SAN fabric. IBM Spectrum Virtualize can handle one, two or even four separate fabrics. Let's assume you have a dual-port Host Bus Adapter (HBA) in server 1, and two redundant fabrics. We will connect each server port to each FCP switch. Likewise, we will connect each FCP switch to the FlashSystem 900, carve up "Volume 1", and create SAN "Zone A1" and "Zone A2", which identify "Server 1" as the initiator, and "FlashSystem 900" as the target. This is all basic stuff.
For those who want to follow along, I suggest you review the full implementation guidance in the IBM Redbook [Implementing the IBM Storwize V7000 Gen2]. Here is an excerpt:
"All Storwize V7000 Gen2 nodes in the Storwize V7000 Gen2 clustered system are connected to the same SANs, and they present volumes to the hosts. These volumes are created from storage pools that are composed of mDisks presented by the disk subsystems. The fabric must have three distinct zones:
Second, we connect the Storwize V7000 Gen2 to the FCP switches. You don't need to connect all of the ports, but I recommend that you have each controller node to each FCP switch, requiring four cables. Add more connections for added performance bandwidth.
Carve up "Volume 2" and this will be referred to as a "managed disk", mDisk for short, and create a "storage pool" which were formerly known as a "managed disk group" which is why you often see MDG in the naming conventions and examples. Storage pools can have one or more managed disks, and you can add more dynamically as needed.
The "storage zone" indicates the Storwize V7000 Gen2 as the initiator, and the FlashSystem 900 as target. If you want to increase the performance bandwidth, consider more cables between the FCP switches and the FlashSystem 900. We create "Zone B1" and "Zone B2". I recommend a separate "storage zones" for each additional storage system that you choose to attach to the Storwize V7000 Gen2.
The "cluster zone" that connects all of the Storwize V7000 Gen2 node ports together for node-to-node (intra-cluster) communication. Storwize V7000 Gen2 ports can serve as both initiators and targets dynamically. For example, when you write to one node, the node then copies the cache block over to the second node so there are two copies stored safely on separate nodes. Since we have two fabrics, we create "Zone C1" and "Zone C2".
Third, we connect "Server 2" to FCP switches, same as we did with "Server 1". We create "Volume 3" which is a "virtual disk, or vDisk for short, from the storage pool containing Volume 2. The "host zone"indicates Server 2 as the initiator, and Storwize V7000 Gen2 as the target. We create "Zone D1" and "Zone D2". I recommend putting each additional server in its own set of host zones.
In theory, you could have a server connected to both Volume 1 and Volume 3. For example, a Windows server would have a "C:" drive connected directly to FlashSystem 900 for high-speed performance, and have a "D:" drive on Storwize V7000 Gen2 to contain data. The Storwize V7000 Gen2 introduces 60 to 100 microseconds of added latency, but provides added value such as FlashCopy, Thin Provisioning, and Real-time compression.
Of course, there are unique situations that might require special configurations, depending on the servers, operating systems, host bus adapters, FCP switches, and storage systems involved.
Continuing my business trip through Canada, an article by Richard Blackwell titled [The Double Bottom Line] yesterday's Globe and Mail newspaper caught my attention.Here is an excerpt, citing Tim Brodhead, president of the J.W. McConnell Family Foundation in Montreal:
The bottom line for any business is making a profit, right?This fiduciary duty to maximize profits is discussed in the 2003 docu
If you buy a (RED) product from GAP, Motorola, Armani, Converse or Apple, they will give up to 50% of their profit to buy AIDS drugs for mothers and children in Africa. (RED) is the consumer battalion gathering in the shopping malls. You buy the jeans, phones, iPods, shoes, sunglasses, and someone - somebody’s mother, father, daughter or son - will live instead of dying in the poorest part of the world. It’s a different kind of fashion statement.
Another example is IBM's recent press release [IBM Plans Investment Increase in Sub-Saharan Africa]:
The company, which has operated in Africa for nearly six decades, expects to increase its investment by more than $US120 million (more than R820 million) over the next two years. In the coming year, IBM expects to hire up to 100 students from Sub-Saharan universities to meet the growing demand in services, global delivery and software development.A recent IBM Global Innovation Outlook (GIO) [report on Africa] indicates that the economies ofdozens of African nations are growing at healthy rates, the best in the past 30 years, with 5.5 to 5.8 percent averageacross the continent. This supports last month's news that [Top IBM thinkers to mentor African students]:
Hundreds of IBM scientists and researchers will mentor college students in Africa. Called Makocha Minds (after the Swahili word for "teacher"), the program will reach hundreds of computer science, engineering and mathematics students.
Mentoring via email and online collaboration is very reasonable. I have mentored both high school and collegestudents through a partnership between IBM Tucson and the Society of Hispanic Professional Engineers[SHPE]. While thekids were all located in Tucson, I rarely am, traveling nearly every week, but I madetime for the kids via email and online collaboration wherever I happened to be.Innovation that matters: XO laptop], you have a second chance! Wayan Vota indicates on his blog [OLPCnews.com] that the program has been extended to December 31, and has [gone global].

Last week, David Pogue (New York Times) wrote a blog entry on The Dilemma Over Future Storage Formats.
Of course, he is focused on the home user, and not the bigger mess found in the corporate world, where Federal Rules like the one past last week that begin to mandate that all U.S. companies archive every e-mail and instant message (IM) generated by their employees.
However, the article does bring up issues that effect the corporate world as well. Its not the "format" as much as the medium/player interface. A friend of mine just bought a vintage 8-track-tape player, but has only one 8-track tape to try it out with. He is now looking on eBay for other 8-track tapes.
The idea of keeping old drives around to read back data is not new. A company called eMag Solutions has all kinds of older tape drives to help companiesretrieve data on their older 3420 and 3480 tape cartridges.
The problem is not just accessing the data on the media, but rendering the "ones" and "zeros" into meaningful information. For example, suppose I saved a copy of my Quicken Tax file every year, and copied them onto a singleDVD for long term storage. The problem is that to access 2002 tax data, I have to run that version of the Quicken 2002 program, and hopefully that version will run on my current computer equipment and operating system.
A client I visited earlier this year had to retrieve 4-year-old Oracle data for litigation reasons. However, to make sense of the data, they had to build a server with a down-level version of AIX and down-level version of Oracle to match the level supported by their homegrown application.
One solution might be to find a new format that is appl Luckily, for the corporate world, IBM has a lot of experience in this area, is the leader in Content Management, offers the world's fastest archive/compliance storage, the DR550, clocked at three times faster than the EMC Centera, WORM tape on LTO Generation 3 and 3592 tape cartridges, and software designed to render older formats into readable form. For the home user, IBM's recent "Innovation Jam" identified this as one of the top 10 ideas, the idea of "Digital Me", storing not just old tax documents, but photos, music, home videos, and so on. My aunt Nancy passed away, leaving me a box of old VHS tapes, which I will watch this month as I sort through all my paper receipts getting ready to file for 2006 taxes.
