Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that many people make for their own personal lives: staying on a budget.
Often, when faced with a tightening budgets, we try to make more use of what we already have. Tell someone they are only using 10 percent of their brain, and they immediatelybelieve you; but tell them they are only using 30 percent of their storage, and they ask for a whitepaper,magazine article, or clarification on how that percentage is calculated. I actually visiteda customer that was only using6 percent of the storage attached to their Windows servers!
So, to help those of you making data center resolutions to stay on budget, the terms to remember are "Reduce", "Reuse" and "Recycle".
When people come to request storage, are they being reasonable about what they need today, or are they asking for what they might need over the next three years? They might need 50GB, but they ask for 100GB, in case they grow, and a year later, you find they have only 15GB of data on it. On the flipside, the person asks for what they need but some storage admins give out more, just so they don't have to be bothered so often when growth happens. Finally, I have seen this formalized into fixed size LUNs, all the disk is carved into big huge 100GB pieces, so if you need 20GB, here's one big enough with plenty of room to grow.
If you are going to keep on a budget, remember that storage today is 30% more expensive than storage next year. That is the average drop in both disk and tape on a dollar-per-MB basis. If there is any way to postpone giving out storage until it is actually needed, you can save a bundle of money. Timing is everything! In the event of a disaster, getting immediate replacement for disk can be very expensive, but if you can wait just two weeks, you can negotiate a better deal. I thought of this while going to the movie theatre yesterday. A "hot dog" and a bottle of water was $8.00, but if you are able to wait two hours and eat after the movie, you can get a much better meal for less.
A lot of companies buy new storage because their existing storage isn't fast enough, or doesn't have the latest copy services. This can easily be solved with an IBM SAN Volume Controller (SVC). The SVC can virtualize slower, functionless storage, and present to your application hosts virtual disks that are faster, and with all the latest disk-to-disk copy services like FlashCopy, Metro Mirror, and Global Mirror.
Chances are, you have unused disk capacity spread across all your storage today, but perhaps they are formatted into small LUNs. The SVC can combine the capacity, and let you carve up big LUNs at the sizes you need.This is like taking all those tiny pieces of soap in your shower and forming a new bar of soap, or taking all the crumbs at the bottom of your bread box, and making a new slice of bread. And, the virtual LUNs are dynamically expandable,so give out only the amount they need today, as it is simple to expand them to larger sizes later.
Of my 13 patents, the first will always be my favorite, on a function called "RECYCLE" for the Data Facility Storage Management Subsystem Hierarchical Storage Manager (DFSMShsm) product, which is now a component of the IBM z/OS operating system. Basically, tapes could contain hundreds or thousands of files, such as backup versions or archive copies, and these expired on different dates. As a result, a tape would be written100 percent full, and then over time, decrease in valid data to 80, 60, 40, 20 until it hit 0 percent. In some cases, a single filecould hold an entire tape hostage. RECYCLE was able to read the valid data off tapes that were perhaps less than 20 percent full, and consolidate them onto fewer tapes. As a result, a whole bunch of tapes could be returned to the scratch pool, and reused immediately for other workloads. This also helps in moving to newer, higher capacity cartridges, such as the new 700GB cartridge that IBM co-developed with FujiFilm.(This RECYCLE function exists in our IBM Tivoli Storage Manager software, as well as our Virtual Tape Server, but is called "reclamation" instead, to avoid confusion on searches.)
When evaluating your use of tape, determine if you are making best use of the tapes you have now, and perhaps a RECYCLE (or reclamation) scheme may be in order. Fewer tapes can save money in many ways, such as reduced storage costs, and reduced courier costs to send the tapes offsite. Tape media can still be 10-20 times less expensive than disk, based on full capacity.
This year I resolve to be more consistent in my blogging, and my goal is to give you one to five entries per week, every week, based on the advice from Glenn Wolsey, Jennette Banks, and others.On some weeks, I will have a running theme, so rather than super-long entries to cover everything I can think of on a topic, make the entries short and readable. This week is a good time to review last year's "New Year's Resolutions" and to make new ones for 2007. I will discuss actions that companies can adopt for their data centers.
A common resolution is to lose weight, as in this Dilbert comic. Last year, I resolved to lose weight in 2006, and am delighted with myself that I lost eight pounds. When people ask for the secret of my success, I whisper in their ear "Eat less, exercise more." In general, people (and companies) know what to do, but just don't do it, which Pfeffer and Sutton document in their book The Knowing-Doing Gap. In my case, it involved lifestyle change: I exercised at a gym three times per week in Tucson, with a personal trainer, and revamped my diet.
Not everyone subscribes to the "eat less exercise more" philosophy. For example, Ric Watson argues in his blog that you can eat fewer calories, but eat more in actual volume, by choosing the right foods. This brings up the issues of "metrics" that most data centers are familiar with. Last year, I read the book "You: On a Diet" which explains that it is better to focus on "waist reduction" as measured in inches around your mid-section at the belly button, than "weight reduction" as measured in pounds. This year, I resolve to get down to 35 inches by the end of 2007.
The problem with measuring "weight" is that you are weighing bones, muscle and fat. A person can gain ten pounds of muscle, lose ten pounds of fat, and the scale would indicate no progress. The same problem occurs in data centers. How many TB of data do you have? Storage admins can easily tell you, but can they tell how much of this is bone (data needed for operating infrastructure), muscle (data used in daily operations that generates revenue) or fat (obsolete or orphaned data)?
We at IBM often state that "Information Lifecycle Management (ILM)" is more lifestyle change than a "fad diet". Figuring out what data you should capture in the first place, where to place it, when to move it, and when to get rid of it, is more important that just buying different tiers of storage hardware. So, for those looking to make new data center resolutions, I suggest the following actions:
Re-evaluate the metrics you now use, and determine if they are helpful in making decisions and taking action.
Come up with new ones that are more focused to solve the issues you face.
Consider storage infrastructure software, such as IBM TotalStorage Productivity Center, to help you gather the information about your SAN, disk and tape systems, calculate the metrics, and automate the appropriate actions.
In his blog, Paul Gillin agrees with Time Magazine's Person of the Year choice of "all of us", those of us who use the World Wide Web to do business or have fun, and to those who contribute to the internet by creating content, such as people who blog or create websites.
So, in continuing my theme this week to recap the best and worst of last year, I list my personal "tech highlights" of 2006.
Programming my Tivo Remotely.
Last September, I realized on a 3-week business trip that I had not programmed my Tivo to record the premieres of each of the new season's television shows. If you miss the first few weeks, it might be difficult to make sense of the rest of the season. Fortunately, I was able to program my Tivo remotely through the internet.
Purchasing TV shows on iTunes
Despite this, I had a repeat episode of "House" record instead of a new episode of
Still unable to make sense of what was going on in the TV show "Heroes", I was able to read the "wiki" which explained all the subtle imagery and background implied.
Using Linux to rescue lost Windows data
My disk drive failed on my laptop, and although I had most of my data backed up with Tivoli Storage Manager prior to my business trip, I had some files that I acquired or updated during the business trip. Thankfully, there are Linux "LiveCD" images that allow you to access your Windows files. You boot these LiveCD images from your CD drive, so there is no installation of Linux on the hard drive itself. If you travel as much as I do, consider bringing along some Linux CDs to get you out of trouble.
Connecting my home entertainment system to my Mac
I now have an 802.1g (54Mb) wireless hub which allows my Tivo to connect wirelessly to the internet to get daily updates, but also allows me to play all my music stored on my Mac through my home entertainment system, and I can also listen to thousands of radio stations through "Live365.com". My favorite station is "Depeche Mode Inspired" which plays songs by Depeche Mode, as well as cover versions by a variety of others.
Learning to Blog
Believe it or not, there is a right way and a wrong way to blog, and this year has been a good learning experience. IBM has a fairly healthy blogging policy, but nonetheless, say the wrong thing and I could be in serious trouble. Fortunately, that hasn't happened, and I am glad to see a fairly open exchange of ideas among the set of bloggers that discuss storage issues.
Building a Snowman in Second Life
I have been a member of Second Life now since November, but it wasn't until I entered a competition to build avirtual snowman last week that the potential of this new interface became obvious to me. There is still lots to learn, but at least now I see value in spending more time and effort learning more about it.
Getting an all-in-one printer/scanner to work with both my Mac and IBM PC
I didn't think it could be done, but here it is, my all-in-one Printer/Scanner works correctly, seemlessly, from both my Windows PC and my Mac Mini, and I have it on my home network so my laptop can use it also, wirelessly!
Using Google Language Tools to translate materials to Portuguese
I speak several languages, enough to order food in restaurants and to get around through various modes of transportation, but translation for a technical audience is more challenging. A class we normally conduct in pure English was taken to Sao Paulo, Brazil, and although most students know some amount of English, we thought it would be good to translate the test questions to Brazillian Portuguese. I took the questions and ran them through a number of translation services websites, and had local IBMers review the results. The winner was Google language tools, which required hardly any edits to the generated text. The class was a big success.
Digital Cameras and CD Burners
As I travelled from Brazil to Bolivia last August, I met a young back-packer who was on her way to Peru, but was staying in La Paz for a few days. We had a great time together, and I was able to transfer the digital photos from my Canon PowerShot digital camera into my laptop and burn her a CD to take with her to Peru.
Painting my Dining Room table
After Halloween, I accidently left my pumpkin jack-o-lantern on my kitchen table as I left for a trip, and when I got back, it had decomposed and left a terrible stain on the wood surface. After sanding the table, I determined that the best course of action was just to paint the surface. I could have just painted it a solid color, or maybe a faux finish with two colors, but instead, chose to copy a famous painting, "Le Cafe" by Alberto Magnelli. I was able to scan this into my computer, resize it, and then project the image onto my table, to then outline the image and paint. I know I would not have been able to do this free-hand.
I am sure there are other triumphs I had throughout the year, but these are the first the come to mind.
'Those who cannot remember the past are condemned to repeat it.' --- George Santayana
This last week of 2006 seems like a good time to recap the past year, and review the upcoming new year.That said, a good start is PC World's Top 21 Tech Screwups of 2006.
Laptops made the news this year in a variety of ways. #1 was exploding batteries,and #6 were the stolen laptops that exposed private personal information. Someone I knowwas listed in one of these stolen databases, so this last one hits close to home. Securityis becoming a bigger issue now, and IBM was the first to deliver device-based encryptionwith the TS1120 enterprise tape drive.
IBM makes the chips used in all the major game consoles: Microsoft's Xbox 360, Nintendo's Wii,and Sony's PlayStation 3. Being all based on IBM technology doesn'tmake the games interoperable or compatible, and in the case of Sony, it made #8 for being incompatible with their own PlayStation 2.Sadly, Nintendo's Wii had its own set of problems, and I found this parody of asafety video on YouTubeyou might enjoy.
Microsoft had #5 (not understanding the holiday shopping season ends in December), #12 (not understanding people who use PCs prefer privacy), and #17 (not understanding how people useMP3 music players). At least they delivered their latest Xbox with minimal problems.As an engineer, taking on a market strategy role involved reading books and taking classeson marketing. I learned that it is all about understanding the marketplace well enoughso that your prospects "know, like, and trust" your company. Perhaps Microsoft should take a refresher course.
A few companies showed off their brilliant customer service. Comcast is representedin a video on #7, and AOL in a taped phone conversation on #15. Many of our clients areafraid of vendor lock-in, and how difficult it might be to undo the deployment of new storagetechnology. Fortunately, IBM is committed to open standards, making it easier for our clientsto make the right choice and feel good about it.
Hopefully, we can all learn from the mistakes of others, and not repeat them in 2007.
