This week and next I am touring Asia, meeting with IBM Business Partners and sales repsabout our July 10 announcements.
Clark Hodge might want to figure out where I am, given the nuclearreactor shutdowns from an earthquake in Japan. His theory is that you can follow my whereabouts just by following the news of major power outages throughout the world.
So I thought this would be a good week to cover the topic of Business Continuity, which includes disaster recovery planning. When making Business Continuity plans, I find it best to work backwards. Think of the scenarios that wouldrequire such recovery actions to take place, then figure out what you need to have at hand to perform the recovery, and then work out the tasks and processes to make sure those things are created and available when and where needed.
I will use my IBM Thinkpad T60 as an example of how this works. Last week, I was among several speakers making presentations to an audience in Denver, and this involved carrying my laptop from the back of the room, up to the front of the room, several times. When I got my new T60 laptop a year ago, it specifically stated NOT to carry the laptop while the disk drive was spinning, to avoid vibrations and gyroscopic effects. It suggested always putting the laptop in standby, hibernate or shutdown mode, prior to transportation, but I haven't gotten yet in the habit of doing this. After enough trips back and forth, I had somehow corrupted my C: drive. It wasn't a complete corruption, I could still use Microsoft PowerPoint to show my slides, but other things failed, sometimes the fatal BSOD and other times less drastically. Perhaps the biggest annoyance was that I lost a few critical DLL files needed for my VPN software to connect to IBM networks, so I was unable to download or access e-mail or files inside IBM's firewall.
Fortunately, I had planned for this scenario, and was able to recover my laptop myself, which is important when you are on the road and your help desk is thousands of miles away. (In theory, I am now thousands of miles closer to our help desk folks in India and China, but perhaps further away from those in Brazil.) Not being able to respond to e-mail for two days was one thing, but no access for two weeks would have been a disaster! The good news: My system was up and running before leaving for the trip I am on now to Asia.
Following my three-step process, here's how this looks:
Step 1: Identify the scenario
In this case, my scenario is that the file system the runs my operating system is corrupted, but my drive does not have hardware problems. Running PC-Doctor confirmed the hardware was operating correctly. This can happen in a variety of ways, from errant application software upgrades, malicious viruses, or in my case, picking up your laptop and carrying it across the room while the disk drive is spinning.
Step 2: Figure out what you need at hand
All I needed to do was repair or reload my file sytem. "Easier said than done!" you are probably thinking. Many people use IBM Tivoli Storage Manager (TSM) to back up their application settings and data. Corporate include/exclude lists avoid backing up the same Windows files from everyone's machines. This is great for those who sit at the same desk, in the same building, and would be given a new machine with Windows pre-installed as the start of their recovery process. If on the other hand you are traveling, and can't access your VPN to reach your TSM server, you have to do something else. This is often called "Bare Metal Restore" or "Bare Machine Recovery", BMR for short in both cases.
I carry with me on business trips bootable rescue compact discs, DVDs of full system backup of my Windows operating system, and my most critical files needed for each specific trip on a separate USB key. So, while I am on the road, I can re-install Windows, recover my applications, and copy over just the files I need to continue on my trip, and then I can do a more thorough recovery back in the office upon return.
Step 3: Determine the tasks and processes
In addition to backing up with IBM TSM, I also use IBM Thinkvantage Rescue and Recovery to make local backups. IBM Rescue and Recovery is provided with IBM Thinkpad systems, and allows me to backup my entire system to an external 320GB USB drive that I can leave behind in Tucson, as well as create bootable recovery CD and DVDs that I can carry with me while traveling.
The problem most people have with a full system backup is that their data changes so frequently, they would have to take backups too often, or recover "very old" data. Most Windows systems are pre-formatted as one huge C: drive that mixes programs and data together. However, I follow best practice, separating programs from data. My C: drive contains the Windows operating system, along with key applications, and the essential settings needed to make them run. My D: drive contains all my data. This has the advantage that I only have to backup my C: drive, and this fits nicely on two DVDs. Since I don't change my operating system or programs that often, and monthly or quarterly backup is frequent enough.
In my situation in Denver, only my C: drive was corrupted, so all of my data on D: drive was safe and unaffected.
When it comes to Business Continuity, it is important to prioritize what will allow you to continue doing business, and what resources you need to make that happen. The above concepts apply from laptops to mainframes. If you need help creating or updating your Business Continuity plan, give IBM a call.
Well, I have left Japan, and while everyone else is enjoying the Super Bowl, I am now in Australia, at another conference.Today I had the pleasure to hear filmmakers talk about their successes, and how IBM helps the movie industry.
At one extreme was Khoa Do, independent filmmaker. After acting in movies asideMichael Caine and Billy Zane, he decided to become his own director. He started a project to help seven disadvantaged youths from a poor drug-ridden section of Sydney, by having them act in his first full-length film.Armed with only an IBM laptop and small budget, he made the film called "The Finished People" that had critical acclaim.
The film was a success, and many of the disadvantaged youths have gone on to act in other movies. In 2005, Khoa Do was named "Young Australian of the Year".
Thanks to IBM technology, filmmaking is now accessible to a wider number of aspiring wanna-be directors. It is no longer necessary to be part of a large film studio with a multi-million dollar budget to tell your story.
At the other extreme, was Xavier Desdoigts, director of technical operations at Animal Logic, the Computer Graphics (CG) arthouse that produced special effects of movies like "The Matrix", "House of Flying Dragons" and "World Trade Center". They started with producing digital effects for TV commercials, like this one forCarlton Draught Beer.
With the support of a large film studio and multi-million dollar budget, Animal Logic now boasts the 86th most powerful "Supercomputer" based on IBM BladeCenter technology, with over 4000 servers connected into a cluster, for making the movie "Happy Feet". The movie took four years to make, with over 500 people, of 27 different nationalities. It was the first CG movie made in Australia, and has been well-received by audiences worldwide.
Mr. Desdoigts gave out some interesting facts and figures about the movie:
While visually stunning on the big screen, each frame is only 1.4 Megapixel, about the same resolution as most camera phones.
In one scene, there are 427,086 penguins all appearing on frame.
Mumble, the lovable lead character, is made up of over 6 million feathers.
As many as 17 dancers were "motion-captured" to choreograph the tap-dancing and character interaction segments.
Only one system admin was needed to manage this entire server farm. (IBM Systems Director technology makes this possible)
The movie consumed 103 TB of disk space, backed up to 595 LTO tape cartridges.
An estimated 17 million CPU-hours were needed for all the processing and rendering.
Rather than talking about technology for technology sake, these filmmakers showed how technology couldbe put to use, in a practical sense, to provide the world something of value.
The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
Our newest offering is the IBM System Storage DS3000 series. Some analysts call this category "low end", but IBM prefers using "entry level". These have an attractivelow acquisition price, very easy to set up, and are intended for the Intel and AMD servers, such as IBMBladeCenter, System x, as well as servers from HP and Dell. Disk arrays in this category typically have listprices below $50,000 USD.
Our midrange offering is the IBM System Storage DS4000 series. These are designed for Linux, UNIX and Windows based workloads.Some call these server platforms "open systems", or sometimes "distributed systems". The DS4000 systems are rack-optimized modularunits, providing plenty of options and trade-offs between price and performance for price-sensitive customers.The "high end" model of the DS4000 series is the DS4800, and has very impressive performance characteristics.Disk arrays in this category typically have list prices in the $50,000 to $299,000 USD range.
IBM System Storage DS6000 seriesis one of our enterprise class offerings. DS6000 offers mainframe attachment comparable to what EMC DMX or HDS USP offer for their "enterprise class" or "high end" models, but uses substantially less power and in a much more compact modular rack-optimized packaging. Disk arrays in this category typically have list prices at $300,000 USD and above.
Super High End
Perhaps IBM and EMC can work together to petition IDC to adopt this as a new category, based on performance,rather than list price. Is the storage marketplace ready for a fourth category?As Chuck mentioned on his blog, IBM is #1 for mainframe disk storage, and perhaps it is because the IBM System Storage DS8000 Turbo series does so well on most mainframe workloads. No offering from EMC or HDS meet or beat the SPC benchmarks for the DS8000 Turbo. You can see the results in the Executive Summary or read the Full Report.
Thanks to IBM's innovative Adaptive ReplacementCache algorithm, IBM DS8000 performance shines best handling read-intensive random-access workloads that mainframes do most often. These types of workload are modeled by the SPC-1 benchmark. In cases of write-intensive, sequential processing, the differences are less substantial, as disk arrays from all manufacturers drop down to the native performance capabilities of the 10K and 15K RPM drives.
I'll give you a real example. Not long ago, I waspart of a team to help resolve a performance bottleneck on-site at the customer location. The customer had an interesting "composite application" where data was processed on AIX platform (IBM System p), which passed the data to a Linux partition running on the IBM System z mainframe,which in turn used Java SQL to post updates to a DB2 database on z/OS partition, which then wrote out through FICON adapters to an HDS USP device. IBM and HDS worked together to help the customer figure out why they weregetting disappointing throughput and response times. IBM brought in experts on AIX, TCP/IP, Java, Linux, z/OS and FICON. HDS had their experts too, and tried to improve performance by quadrupling the storage capacity, and spreading the data out across more spindles. That didn't work. As it turns out, HDS disk just couldn't deliver the performance required. The software and mainframe were all well tuned. They replaced the HDS withan IBM DS8000 array, and it met all the service level requirements. Problem solved.
The problem with having this new "super high end" category, of course, is that only IBM plays in it, so it wouldn'toffer the marketplace much of a comparison. For now, we'll just have to settle for being the fastest in the samecategory as EMC DMX and HDS USP.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers. Not all workloads are mission-critical or performance-sensitive. For less critical workloads, perhaps you may find EMC or HDS performance is "good enough".
But if performance is important to you, you should consider IBM on your list of vendors for your next purchase decision. Let IBM help you prove it to yourself, running your specific workloads side by side with your existing equipment.
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 application-independent. Flat text files, Adobe PDF format, MP3 audio files, HTML pages, and JPEG photo images are often used to avoid the requirement of special applications to make sense of the data.Unfortunately, in some countries, the laws actually dictate that business must keep their data in the original "digital format". So, if it was a MS WORD v1 document, it must be kept in v1 format, even though today's WORD 2002 can't even make sense of it, and you have to go to IBM or some other third party that have "rendering tools" that understand these older formats.
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.
Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape, with four specific examples. There was a lot of reaction and reflection fromboth sides.
On the one side...
EMC blogger Mark Twomey at Storagezilla admits that perhapsTape Isn't Dead after all,is perhaps the best place to put long-term archive data, but not for backup? EMC's "creative marketing types" put out this Fun With Tape video that I found amusing. (It asks for a first name,last name, and e-mail address, which are then embedded into the resulting video itself, and perhaps forwarded to your nearest EMC sales rep, so answer according to your wishes for privacy).
The "mummy wrapped in tape media" seems to be a common theme, and shows up again in LiveVault'svideo with John Cleese, which makes the same argument asthe EMC video above, namely: switch your backups from tape to disk because we are a disk-only vendor.
... and on the other side
JWT over at DrunkenData asks Which is greener, disk or tape?Tape is, of course, by a long shot, and an essential part of IBM's Big Green initiative, a project to invest$1US Billion dollars per year for data centers to be more efficient for power and cooling.
Sun/StorageTek blogger Randy Chalfant questions the Death of Tape, and argues thatdisk-only solutions suffer from atrophy.The results he posts from a survey of 200 customers are similar to those we've seen with customers using IBM TotalStorage Productivity Center, our software to help evaluate data usage, and identify misuse, in your data center.
To my readers in the USA, United Kingdom, Ireland, South Africa, China and Japan, and a few other countries, Happy Father's Day!
For those who participated in Clark Hodge's "Where's Tony" contest,I was in Croatia, Bosnia and Herzogovina. There were optional side-tours to Montenegro and Slovenia, but I decided not to incur the added time and expense with those.
For those wondering where to go this Summer for vacation, I recommend Croatia. It is a beautiful country, with clean cities, good road conditions, and a calm Adriatic sea as we went from island to island.
And if you get to Mostar, don't let them talk you into jumping off the "old bridge". The water is terribly cold down there![Read More]
(Note: I am neither a medical doctor nor registered dietician. I can share with you ideas that have worked for me (or people I know) that might help you achieve your goals. I strongly suggest you read books and consult with medical experts as necessary.)
The problem is that most people think of dieting as something you do temporarily. People decide to lose weight, go on a diet, reach their target goal weight, go back to their previous ways, and gain the weight back.
The word Diet comes from the Greek language and means "way of life". Every day that food enters your mouth, you are on a diet. People aren't on or off a diet, but rather switch from one diet to another. The trick is to find a healthy diet that you can live with the rest of your life, so your weight doesn't go up and down.
Most health experts agree that the [Western pattern diet], typical in the United States and other developed countries, is [certainly not healthy]. Washing down that bologna-and-cheese on white bread sandwich with a 44-ounce high-fructose soft drink hasn't served Americans well. This combination of processed meats, refined grains, dairy, and sugar-laden foods has shown to cause obesity and other health problems.
Physicians at Cornell University found that [men take better care of their cars than their bodies]. If you tell a guy that his car takes 12 gallons of high-octane gasoline, 5 quarts of 5W-30 oil, and a 50/50 mix of water and anti-freeze, he would totally understand what you mean.
But tell that same guy that his diet must consist of an appropriate ratio of complete proteins, monounsaturated fats, and carbs with a low glycemic index, and he will scratch his head. Aren't calories just calories?
Unlike a car, where the gasoline, oil and anti-freeze get poured into different openings into fixed metal containers, the human body takes in all of the things it needs in one opening, your mouth, and receives it into a stretchable container, your belly. While carbs are just converted to fuel, the proteins and fats have actual functions and bring building blocks that cannot be built from just carbs alone.
Carbs are found mostly in foods like fruits, grains and vegetables. Not all carbs are the same. Some break down quickly to glucose, the sugar molecule that represents fuel for the rest of your body. Others break down slowly. Consider a fireplace, you put a few pieces of newspaper or kindling, and the larger logs on top. The newspaper is easy to light, but burns quickly. The logs on the other hand burn slowly and give you hours of heat.
Eating the Western pattern diet is like filling your fireplace with newspaper, and having to re-light your fire over and over after all the newspaper burns out.
Proteins are the building blocks of your muscles and other internal organs. These are built from amino acids, and your body can't make them, you have to have them in your diet. Even if you lead a sedentary lifestyle, sit all day at a desk, then sit all evening in front of the television, your body needs to repair internal muscles and organs with proteins, so you need to eat proteins every day to replenish these amino acids.
Complete proteins, such as those in beef, eggs and fish, have all the amino acids represented. Plant-based proteins, like rice, beans, and wheat, are incomplete, lacking one or more of the amino acids you need.
Fats are needed to absorb fat-soluble vitamins, which are important for a variety of functions. Monounsaturated fats can be found in olive oil, nuts, and avocados. While many people feel the saturated fats in red meat and dairy are bad for your health, there are exceptions. Coconut milk is high in saturated fats, but good for you.
There is some dispute and controversy on exactly what is an ideal diet. This can be partly attributable to articles that report findings from observational studies, rather than from double-blind clinical studies. To understand the difference, I suggest you watch Tom Naughton present [Science for Smart People] in this amusing 46-minute video.
Over the past few years, I have tried out several different diets, to figure out which one is best for me. I'll save those details for my next post.
The Harvard Extension School is running a course focused on virtual law with a Second Life component. Rebecca Nesson (’Rebecca Berkman’ in Second Life) is teaching the class. The lectures, which look fascinating, are available to at-large participants on Berkman Island [SLURL: http://slurl.com/secondlife/Berkman/113/70/24].
You can attend the lectures in Second Life on Monday evenings from 8:00-10:00pm EST (5:00-7:00pm SL time). Videos of past lectures are linked on the course’s web site, where you can also find the syllabus, a wiki, and more.
The US version of The Office (which does an excellent job of being almost as funny as the BBC version) is no stranger to life online. It’s fun to spot Kevin, Meredith, Creed, Roy, Pam all on MySpace, and Dwight has a blog. This week they dipped into Second Life. The very same week as CSI:NY; It’s all getting very mainstream.
Of course, the Office’s treatment of SL was as tongue-in-cheek as you’d expect…
Dwight:“Second Life is not a game. It is a Multi User Virtual Environment. It doesn’t have points or scores or winners or losers.”
Jim:“Oh, it has losers.”
Steve Nelson at Clear Ink, the team behind bringing the office into SL for the episode, has [written about the project] and carefully lists the locations and clothing used.
I watched this episode and loved how they were able to blend it in seamlessly without looking out of placeor awkward reference.
Cisco Systems Inc. has been staging virtual meetings between developers and channel partners in Second Life for more than a year, but this invitation was a first for me. So a presentation announcing the winners of a networking technology innovation contest -- inside a Second Life simulation -- seemed like the place to be.
I'm probably an SL noob (for newbie) by most standards, but I've spent enough time there to know most of the ways to move and how to search out islands and events.
In all, I would say the Cisco event sparked my interest in the SL virtual meeting format, but my attention was focused more on making things in SL work smoothly than on the material presented.
I've had some interesting conversations with event-coordinators looking for advice on setting up events in Second Life, so I suspect that is a good sign that this is still growing momentum.
Continuing my coverage of the [IBM Edge2014 conference], IBM's premiere conference for System Storage and related products, here are my notes from the afternoon of Day 1 at the general keynote sessions.
Stephen Leonard, IBM General Manager, STG Sales, served as emcee for the general session.
Tom Rosamilia, IBM Senior Vice President, STG and ISC
Tom (my fifth-line manager, BTW) started off with a joke: "All this talk about Cloud, but it has to run on hardware somewhere!"
Tom insists it is imperative for clients to build an infrastructure that enables business growth. However, less than 10 percent of clients are ready for Cloud, Analytics, Mobile or Social (CAMS) initiatives. Clients need to embrace these new workloads, ensure right-time decision making, and integrate front-office with back-office IT systems.
Tom is also proud that IBM's Software Define Storage solutions manage over 1 [Yottabyte] of information today. That's a billion Petabytes, in case you were wondering. If all of this data was stored on 1TB disk drives, instead of a mix of disk and tape, it would take over one million city blocks to house all the data centers required.
Tom indicated that data is to the 21st century what steam was for the 18th century, electricity was for the 19th century, and hydrocarbons were for the 20th century.
Tom invited Mike Reagan, CIO of Cleveland Clinic in Abu Dhabi, to say a few words on why Infrastructure matters to his IT environment. The [Cleveland Clinic in Abu Dhabi] is a 364-bed multi-specialty facility, the first US-hospital replicated outside of North America.
Mike explained their great success partnering with IBM to develop a private cloud solution. Each patient has a bedside tablet that can be used to control the entertainment, lighting, temperature and window shades. It can also be used to Skype with family and friends. The facility is four times the floorspace of the Sands Expo that this event is being helenovo 61 CES awardsld in.
Jamie Thomas, IBM General Manager, Storage and Software Defined Systems
Jamie feels that data is all about security and economics. Storage admins must become the new [data scientists] for IT.
It is important to integrate traditional "Systems of Record" with new "Systems of Engagement" workloads. Her focus areas are Software Defined Storage, Flash technologies, and storage virtualization. Specific examples included:
Mike talked about how important Electronic Health Record [EHR] systems and advanced clinical diagnostics are to help make the right medical decisions.
Greg explained that Citi was operating at global scale in 100 countries. Citi partnered with IBM to deploy commodity compute servers, 10GbE/40GbE Ethernet networking and IBM Software Defined Storage to achieve Cloud economics and Cloud scale. Citi can't afford for server, storage and network admins to work separately.
Rather than contesting [Hewlett-Packard CEO Meg Whitman's FUD about this deal], Adalio took the high road, and focused on IBM's success in the x86 server space. New offerings include the X6 architecture, including PureSystems and the NextScale dense computing platform.
Adalio invited Christian Teismann, Lenovo, on stage. Christian re-iterated that IBM and Lenovo are both committed to a smooth transition, continuing IBM's roadmap for the x86 server platform, and full consideration for the x86 servers and related storage, software, service and maintenance.
IBM has had a strong relationship with Lenovo already with the acquisition of IBM's PC division, and now this deal brings together Chinese supply chain efficiency with Western ideals and design principles. Lenovo has about 46,000 employees, nearly 4,000 R&D engineers, and will acquire an additional 7,500 IBMers when the deal completes.
Adalio then invited two clients to join him on stage: Ron Grabyan, Manager of Data Warehousing Services at [Southern California Edison], and Rohit Lal, IT Direction of Coca-Cola.
Ron indicated that actionable insights must be fast for productivity. He mentioned the funny [MetLife television commercial featuring Charlie Brown and Lucy] declaring that term-life insurance should cost only "five cents" per month. In the same manner, end users often request that response times should be short. IBM was able to get response times from 40 seconds down to "5 seconds" by helping Ron deploy SAP HANA. Another process that took 53 minutes was down to 1 minute 20 seconds.
Rohit talked about their exciting new "Coke One North America" (CONA) project. This will provide consolidated IT services for 6 different Coca-Cola bottlers in North America. With $46 Billion USD in revenue serving 1.8 billion servings of beverage per day, the use of Analytics, SAP HANA and private cloud were critical to their business.
The industry recognizes Lenovo as a major x86 player, having had 20 quarters of growth outpacing the market. Lenovo has [won 61 CES 2014 awards], more than the other top five x86 vendors combined. IBM x86 servers are ideal for Enterprise solutions, Cloud, HPC, embedded designs, and IT infrastructure deployments. IBM is #1 in x86 server customer satisfaction, #1 in x86 server up-time, and boasts the #1 fastest x86-based supercomputer. IBM and Lenovo want to take this to the next level: #1 leadership in every x86 category.
For those on Twitter, my handle is @az990tony and the hashtag for this event is #IBMEdge.
From a technology-oriented to a service-oriented approach to IT management
Companies are challenged with shifting from a technology/resource-oriented to a service-oriented approach to IT management. This involves new processes, a new reportingstructure for the IT staff, new tools and technologies, and new data to be captured.A top-down approach is recommended for large organizations, but a bottom-up approachmight be easier to implement for small and medium sized businesses.
IT service management architecture and autonomic computing
IBM has been promoting the concept of Autonomic Computing since 2001. A self-managed resource can have an autonomic manager with sensor and effector. The sensor is used to monitor status, a knowledge basecan analyze and plan for appropriate modifications, and execute these through theeffector. The Autonomic Computing Reference Architecture (ACRA) aligns with the Information Technology Service Management (ITSM) model well, with the CMDB acting asthe knowledge base for the autonomic managers. See my earlier post[Self tuning guitars and storage].
Evolving standards for IT service management
Changes to the IT infrastructure must be closely managed to avoid disruptions.IT organizations recognize that standards-based solutions enable interoperability,with less risk, to connect internal and external applications. Standards can be formally developed by standards bodies like ISO, IETF, W3C, OASIS, and DMTF; or be de facto standards that become widely used by companies, which can then laterbe adopted by standards bodies. SML and SDD are emerging standards that are incompatible with the current set of Web Services-based protocols, like WSDM, but work isunderway to try to determine a unifying standard to support all of these under ITSM.
Prospects for simplifying ITSM-based management through self-managing resources
An ideal computing system would take over a great deal of its own management.Today's IT systems are brittle, difficult to understand, and dangerous to change.The savings from automating some tasks are dwarfed by the irreducible costs of humandecision making, agreements and approvals built in formal processes. A true self-managing, scalable IT system would consist of a number of nearly-identical boxes,with a web interface to define high-level policies and provide information on utilization and performance. As the system needs to expand, it can automatically place the order. When the new boxes arrive, they are placed and connectedinto the data center, and the system configures and provisions them appropriately.
IT Autopilot: A flexible IT service management and deliver platform for smalland medium business
Using an airplane analogy, the pilot performs manual steps to get the plane safelyoff the ground, then turns it over to the autopilot for normal operations. The ITAutopilot intends to do this for IT service management in small and medium business (SMB)that may not have a large dedicated IT staff, using an SOA approach that isloosely coupled, stateless, and adhering to Web Services standards. The IT Autopilotemploys workflow-based controls, the autonomic computing MAPE model, and customizedpolicies to address SMB requirements. It could be deployed as an appliance, similarto IBM System Storage Productivity Center.
This week, the [Global Language Monitor] announced that "Web 2.0" became the One Millionth word of the English language. The average American only uses about 10,000 word vocabulary.
One way to improve your vocabulary is to read my blook (blog-based book), Inside System Storage: Volume I, which includes a 900-word glossary of storage-related terms. My blook is now available in hardcover or paperback at [Amazon] as well as direct from my publisher[Lulu]:
I have started working on a new book which I hope to have available for purchase later this year.
I didn't really have a theme this week, still recovering from jet-lag from my travels through Japan, Australia, China.
Gary Diskman has an amusing blog entry about a Funny disaster recovery job posting. It is not clear if he is being completely tongue-in-cheek, or a bit cynical. However, it rings true that you get what you measure, and some managers look for easy metrics, even if there are unintended consequences.
Western medicine works this way. Rather than paying your doctor to keep you healthy, you pay him per visit, to get refills on prescriptions, check-ups on medical conditions, surgeries and so on. While Eastern medicine is focused on keeping people healthy, Western medicine profits more from resolving "situations".
I have seen similar situations on the "health" of the data center. In one case, the admins were measured on how quickly they bring back up their web-servers after a crash. They had this process down to a science, because they were measured on how quickly they resolved the situation. I suggested switching from Windows to Linux, a much more reliable operating system for web-serving, and showed examples of web-servers running Linux that have been up for 1000 days or more. Management changed the metrics to "average up-time in days" and magically the re-boots all but disappeared, thanks to Linux, but also thanks in part to shifting the incentive structure. Perhaps some of those earlier situations were "artificially created"?
Back in the 1980s, I was working on a small software project that was about 5000 lines of code. In those days, testers were measured by the number of "successful" testcases that ran without incident. Testcases that uncovered an error were labeled as "failures" to be re-run after the developers fixed the code. When I declared my code ready for test, the test team ran 110 testcases, all successfully, and they were all rewarded for meeting their schedule. I, on the other hand, did not accept these results, met with them and told them I would give them $100 each if they could find a bug in my code in the next week. Nobody writes 5000 lines of code without some error along the way, not even me. (As one author put it, more people have left earth's gravity to orbit the planet than have written perfect code that did not require subsequent review or testing. It's so true. Good software is difficult to write.)
The test team accepted the challenge, and found 6 problems, more than I expected, but at least I felt more confident of the code quality after fixing these. As I suspected, the unintended consequence of counting "successful" testcases was that testers would write the most simple, basic, least-likely-to-challenge-boundaries testcases to ensure they meet their numbers. My experiment was costly to me, but more importantly was a wake-up call for the test management, and they realized they needed to re-evaluate their test procedures, metrics and terminology. This was a long time ago, and I am glad to see that the overall "software engineering" practice has matured much over the past 20 years.
So, my advice is to determine metrics that have the intended consequences you want, while avoiding any negative unintented consequences that might undermine your eventual success. People will quickly figure out how to maximize the results, and if you can align their goals to company goals, then everybody benefits.
Well, I'll be blogging from Mexico next week (yes, it is a business trip!). Enjoy the weekend.
This week I was in Palm Springs in meetings with clients, prospects, business partners and IBM sales reps.
Tuesday consisted of "outdoor meetings", but the high winds caused some people to arrive late, and others to land in the various sand traps and water hazards. A "welcome reception" event allowed everyone to socialize and get to know the IBM experts and executives. Two of my colleagues, Mike Stanek and Dave Wyatt, were with me also in Australia last week, and so the three of us were discussing recovery from jet lag.
Wednesday was organized as a main tent event, where everyone met into one large room to hear our strategy,latest set of offerings, and customer testimonials. This was done indoors, of course, which was a good thing as the winds were now gusting up to 50 miles per hour, knocking over windmills and making the local news.
Here's a quick sample from the testimonials:
An insurance company virtualized their IBM DS8000, DS4000, ESS 800 and EMC DMX3 high-end disk with theIBM System Storage SAN Volume Controller and got higher availability and performance. Data migrationefforts that used to take six(6) hours of admin time now took less than one hour, and with no system downtime.They have a total of 350TB virtualized under SVC now, but plan to extend this for a variety of other projects.
A bank presented their success using "Global Mirror" (IBM's asynchronous two-site replication disk mirroring capability).Their previous "business continuity" plan was called 2-20-24 for 2 sites that were 20 miles apart and recovery time objective (RTO) of 24 hours. With the events of Hurricane Katrina, this was considered inadequate, and a new2-200-6 plan was requested, across 200 miles with a recovery time objective of only 6 hours. The chose to deploythis one application at a time, to learn and grow by experience in each phase. They started with Microsoft Exchange e-mail application running under VMware on BladeCenter servers, and wereable to recover remotely within 1 hour. They are now looking to refine and automate the recovery process, perhapswith IBM TotalStorage Productivity Center for Replication and Geographically Dispersed Open Clusters (GDOC).
A healthcare provider presented their success with tiered storage, managing a 475TB mix of IBM DS8000, DS6000,DS4000 and HP EVA disk arrays. The key was having centralized storage management from IBM, which allowedthem to shrink provisioning time from 3 weeks average, to now 96% of their storage provisioning requests are completedin less than 1 week. Moving data between storage tiers was non-disruptive, and the significantcosts savings greatly justified the change in "mindset" that required some training on the new environment.
Thursday we offered a series of "workshops" on specific topics. These were interactive sessions to discuss installation, design and deployment of various solutions. The event ended early enough so that people couldreturn home, or go to the practice range, which reminded me of this inspiring video on How to play golf as well as Tiger Woods.
The event got great reviews, and I look forward to the next one. Until then, enjoy the weekend!
