Continuing my week's theme on travel, conferences, and Japan, I saw two items in the newsthat seem to follow a common theme.
- According to the "The Daily Yomiuri", a local Japanese paper, "double happy weddings" arebecoming more and more popular in Japan. These would be called "stotgun" weddings in the US, butin Japan, couples pay extra to have a wedding between the fifth and seventh month ofpregnancy. As Dave Barry would say, I am not making this up. 27% of couples in Japan got married while or after pregnant. The logic is that they can celebrate both events with one ceremony. Many couples believe that the primary purpose of marriage is to have children, and somethat fail to have children suffer terrible anguish or divorce. Waiting untilbeing pregnant helps ensure the couple will be "successful" in this regard.
- IBM acquires Softek, a software company that develops a product called Transparent Data MoverFacility (TDMF) to move mainframe data from one disk system to another, while applicationsare running. This can be used, for example, to move data from outdated disk systems to IBMdisk systems. This is not to be confused with IBM's archive and retention software partner,Princeton Softech.
Softek is the software spin-off of Fujitsu (a Japanese computer hardware manufacturer). Fora while, Fujitsu made IBM-compatible mainframe servers, but was not successful at developingits own system software, relying heavily on IBM for this. Unable to compete against IBM, it stoppedmaking mainframe servers, but continues making other kinds of hardware equipment.
With TDMF, the process of moving data is simple. The software runs on z/OS and intercepts all writes intendedfor a source volumes on the old array, and re-directs a copy to destination volumes on the new device.Systems can run with old and new equipment side by side for a few weeks, with the new devicestaying in-sync with the old. When the client is ready to cross over, the systems arepointed to the new disk, and the old disk systems are detached and removed from the sysplex.
Afraid that installing TDMF will mess with your applications? IBM Global Technology Services (GTS)is able to roll-in a separate mainframe, move the data, than disconnect it along with the old storage.
(For customers running Linux, UNIX or Windows on other platforms, IBM offers SAN Volume Controller (SVC).While SVC is not marketed as a "data migration device", per se, it does have this capability.Many clients were able to cost-justify purchase of an SVCto move data from old storage to new in similar fashion to how TDMF works on the mainframe.)
What do these stories have to do with one another, other than both relating to Japan? IBM has beenusing TDMF for years as part of a service offering to move data from one disk system to another.Since Sam Palmiasano took over in 2002, IBM has acquired 51 companies, 31 of them software companies.Often, these have been "successful" turning quickly profitable because IBM was already well familiar with the companies they acquire, in much the same way that husbandsare well familiar with their brides-to-be at a "double happy wedding".
So, welcome Softek! It looks like its time to celebrate again!

Continuing my week's theme on travel, conferences, and Japan, I provide three more"survival words" in Japanese language. These might seem like an odd trio, but they comein very handy.
- Domo -- "very much"
- This is short for "Domo Arigato" which is "Thank you very much". If you just say "Domo"they assume you mean the full phrase, and gets the same point across. Some of my older readersmay remember a song by Styx "Domo Arigato Mr. Roboto" which is perhaps the only song I could think ofthat mentions IBM and Japan in the same song.
You're wondering who I am-machine or mannequin
With parts made in Japan, I am the modern man
I've got a secret I've been hiding under my skin
My heart is human, my blood is boiling, my brain I.B.M.
- Doko -- "where?"
- This word is great for trying to find places or things, such as "Where is the restroom?"Sometimes making an attempt to speak a country's official language will garner some respectand appreciation from the locals. If you're lost, and looking for help finding something, this is a great time to be appreciated.
Upon arrival to Narita, I was planning to take the N'EX high-speed train into town, but there was a train accident on the JR line, so I ended up taking the Kisei train over to Nappori station,then transfer over to a different line. Not what I had planned, but an adventure nonetheless.
- Dozo -- "after you" or "go ahead"
- Japan is all about showing respect to your elders, upper management, and others in great esteem or authority. When arriving to a dinner table, or leaving the elevator, this phraselets them know you are respectful by letting them go first. Americans always seem rushed,so it is good to show I can be patient also.

This week I am in Japan, so my week's theme will center around travel, speaking at conferences, and Japan itself. I first travelled to Japan in the late 1980s, to visit a college friend who was working for Ford Motor Company, on assignment in Japan as liasion to Mazda Corp.
Back then, the only Japanese phrase I knew was "Wakarimashta" which means "I know" or "I understand". If you only know one phrase in a foreign language, this possibly could be the worst to know.
My second trip, I was better prepared. I learned three "survival phrases":
sumimasen - "I'm sorry/excuse me"
hanashimasen - "I don't speak"
wakarimasen - "I don't know / I don't understand"
These are great phrases to know individually, but even more powerful strung all together, to emphasize that you will begin speaking English, but at least with good reason (and perhaps a bit of irony.)
I've been to Japan many times since, and have picked up more of the language. When travelling to Japan, or anywhere for that matter, it is important to "pack light". I'll be gone for two weeks, but all I bring is a laptop bag and one carry-on piece of luggage.
I went on a trip to Prague (Czech Republic) with a female co-worker who brought FOUR pieces of luggage. One was just for shoes. Another piece was just for hair styling gel, make-up, face creams and finger nail polish. Today, the rules are different, and the TSA allows only a single quart-size plastic bag containing little jars of 3 ounces or less of liquids or gels. I didn't have any "quart-size" bags, so I used a smaller sandwich-size bag.
What does all this have to do with storage? I've helped many clients move data centers, and this involves moving their servers, their networks, and their storage. Servers and Networks are easy to move, but storage presents some challenges. In many cases, the entire company is shut down, the storage is moved, and then the company is operational again. Needless to say, it is best to do this over a weekend.
I tell clients to "pack light" and figure out what data they really need in the move. What do you really need to operate your business? Bring just that, the rest can arrive later.
This same concept applies for Business Continuity and Disaster Recovery planning. What do you really need after a disaster occurs? Can you run your business for a few weeks on that data, until the rest of the data is restored? If you can't run your entire business on that data, can you run your most important parts of your business?
If you run a bank, perhaps keeping your ATM cash machines running is more important than making out new loans. In Japan, if a bank has any outages that impact their ATM machines, they put out a full page advertisement in the local papers to apologize for the inconvenience.
Business Continuity is one of the nine "Infrastructure Solutions" that IBM can help clients with. If you are interested in learning more on how IBM can help you with your Business Continuity, click here.

Stephen Colbert, of The Colbert Report
, explains the name changes in recent mergers
of the Telecommunications industry. A discussion on "changing names" and how that impacts storage seems like a good way to wrap up the week's theme on naming conventions.
Name changes are sometimes painful, but often times done for a purpose, such as to promote a family. In the US, when a man and woman marries, the woman often changes her family name to match her husband, and the kids all adopt the father's family name. I say "often" because there are times where the woman keeps her name, or adds to it in a hyphenated way. ABC News reported that a Man Fights to Take Wife's Name in Marriage. KipEsquire, a lawyer, writes about it in his blogA stitch in haste.
IT industry changes the names of products that people knew as something else. Other times, they re-use an existing name, when really it is or should be different from the original. Last year, I took on the job of helping transition from our brand "TotalStorage" to the "System Storage" product line under the new "IBM Systems" brand. I help decide what stays the same name or what changes, when it should change, and how to announce that change.
On the disk side, IBM renamed Fibre Array Storage Technology, or FAStT, which was pronounced exactly like "fast", to DS4000 series. This was a big improvement, as people couldn't seem to spell it properly, with variations like "FastT". Nor could people pronounce it properly, saying "fast-tee" instead. The advantage of "DS" is that it is both easy to spell, and easy to pronounce. The DS4000 series continues to be "fast", providing excellent performance for its midrange price category.
IBM's Enterprise Storage Server (ESS) line went from model E10, to F20, to 750 and 800. When IBM came out with its replacement, the IBM TotalStorage DS8000, some people asked why it wasn't named the ESS 900, for example. The DS8000 is quite different internally, new hardware design and implementation, but is highly compatible with the ESS line, and shares much of the same functionality from microcode. Last year, it was replaced by the IBM System Storage DS8000 Turbo. Again, newer hardware, so it was easy to justify the new name change from "TotalStorage" to "System Storage".
Renaming a product risks losing its certifications and awards. For example, IBM spent a lot of time and money getting the OS/390 operating system certified as a "UNIX" platform. When it was renamed to z/OS, IBM had to do it all over again. Learning from this experience, IBM decided not to rename the SAN Volume Controllerto a new designation like "DS5750", as it enjoys the "number one" spot on both the SPC-1 and SPC-2 performance benchmarks, and is recognized as the leader in the disk storage virtualization marketplace. Renaming this product would mean losing that collateral.
IBM's "other disk systems" the N series posed another set of challenges. The current DS line already has entry-level (DS3000), midrange (DS4000) and enterprise-class (DS6000 and DS8000) products. The OEM agreement that IBM has with Network Appliance (NetApp) resulted in a new set of entry-level, midrange, and enterprise-class products. But these didn't fit nicely into the DS3000-to-DS8000 continuum. Instead, IBM decided to go with N series, using N3000 for entry-level, N5000 for midrange, and N7000 for enterprise-class. These are different than the numbers used by NetApp for their comparable, but not identical, offerings.
On the tape side, IBM decided to name the tape drives TS1000 and TS2000 range, tape libraries and automation with a TS3000 range, and tape virtualization to the TS7000 range. A lot of tape products already had 3000 numbering that had to change to fit this new scheme. This is why IBM's popular 3592 tape drive was renamed to the TS1120. The replacement to the 3494 Virtual Tape Server was named TS7700 Virtualization Engine.
Obviously, you can't change the names of products that are currently in the field, but what about existing software with minor updates? IBM decided to leave "TotalStorage Produtivity Center" under the "TotalStorage" brand until it has a significant version upgrade. Many people say "TPC" as a convenient acronym when referring to this product, but TPC is a registered trademark of the Professional Golfers Association (PGA) to refer to its "Tournament Players Club".
How can anyone confuse "managing storage" with "playing golf"? One activity is full of frustration that takes years or decades to master, involving the need to understand a variety of equipment and techniques to use each properly to accomplish your goals; and the other is an enjoyable activity, immediately productive in front of a single pane of glass managing all of your DAS, SAN and NAS storage, from reporting on your files and databases to managing storage networks and tape libraries.
Enjoy the weekend!

Continuing my theme on naming conventions, this time I will talk about finding information.
Industry analysts estimate that information workers spend as much as 30 percent of their working day just looking for information they need, as mentioned in an interview withJeff Teper, Microsoft.A second study of middle managers found similar results, and is discussed in Information Architecture andDM Review.
Take for example looking for information on a specific person. If you were searching for"Barack Obama" or "Lulit Shiferaw", then perhaps you will find exactly the person you werelooking for.
On the other hand, some names are more common. I've met my share of people named John Smith, Jennifer Jones,or Mark Johnson. While PEARSON does not even make the top 100 list of family names here in the US, it isstill fairly common.
People looking for me may realize that I am notHead of Australian Economics at ANZ Bank, author of the book "Don't Read This!", winner of the Killam Teaching Prize, or owner offisheries in Essex.While I do work out at the gym on a regular basis, I look nothing like thisfamous body builder. There are several others, but I pickedjust a few to make my point.
At this time, there is only one "Tony Pearson" working at IBM. A while back, there was a second,a woman who spelled her name "Toni" with an "i" at the end. Her job involved deploying storage on AIX platforms,and was similar enough job description to mine that we would get each other's mail, and sometimes not realize it was meant for the other.
Dan Santow of Word Wise talks about the difficulties of proper names withaccent marks.This would make searching worse, but many search tools can handle this, stripping off allaccent marks to make the comparisons.
But what if you wanted to leave those accent marks in, for an exact match?

On his blog post on preparation
, Seth Godin mentioned an appropriate Swedish saying:
There is no bad weather, just bad clothing.
Appropriate because it snowed here in Tucson, Arizona on Sunday evening, leaving many of us here figuring out how to drive through the stuff on Monday. In my entire lifetime, I have only witness snow down in the Tucson valley a handful of times. It got me thinking about coats, and the wonderful schemes for coat check rooms, as an analogy for data access. A lot of people ask me to compare and contrast one technology from another, say block-level virtualization from content-addressable storage, and so on, and I always try to find a good analogy to help explain things.
Let's start with the setting. It is snowing outside and people are wearing coats. When they come inside, they check their coats at a coat check room, a large room with rows and rows of racks with hangers. A coat check attendant takes your coat and puts it on a hanger, and gives you a ticket or other identifier that will allow you to retrieve your coat later. The ticket must have sufficient information to retrieve the coat quickly, rather than searching rows and rows of hangers for it.
- Block-based disk storage
You walk to the coat-check desk, tell the attendant to hang your coat on a specific hanger, say hanger number 387. When you come back, you ask for the coat on hanger 387. The coat-check attendant knows exactly where hanger 387 is, and is able to retrieve it quickly. Most disk systems use this approach, including IBM SAN Volume Controller and DS family of disk systems.
- Name-based disk storage
You walk to the coat-check desk, tell the person the name that you want to call your coat. An empty hanger is located, and a list of coat names, with their associated hanger number, is then kept. Upon return, you ask for your coat by name, and the coat-check attendant looks up the hanger number to match, and retrieves your coat. This is the scheme used by the IBM System Storage DR550, N series for NAS storage, and the IBM Healthcare and Life Sciences Grid Medical Archive Solution (GMAS).
- Content-addressable storage (CAS)
You walk to the coat-check desk and hand them your coat. The attendant weighs your coat, checks the brand, the size, the number of buttons and zippers, types it all in, and the computer spits out a "hash code" from 1 to 99999. An empty hanger is found, and the hash code is associated to the hanger number. Upon return, you provide the hash code you were given, and the coat-check attendant looks up the hanger number to match, and retrieves your coat.This is the scheme used for some non-erasable, non-rewriteable storage, such as the EMC Centera.
IBM invented hash codes in 1953 as a way to speed up searches. For example, if you want to look up a word in the dictionary, knowing the first letter of the word makes it much quicker, because you can thumb directly to that section. A hash code was intended to give a more even distribution, so that if a million words are stored in a "hash code dictionary" then you would calculate the hash code, then look up only that section of words associated with that specific hash code number.
A problem arises when you generate "hash codes" for storage. It is possible for two different pieces of data to resolve to the same hash code. When an application tries to write a piece of data, and it resolves to a hash code that already exists, that is called a collision. One response is to either compare the incoming data to the data that is already stored, confirm they are identical, but that can be time consuming. The other response is to just assume they are identical, and reject the secondary copy, a process often referred to as "de-duplication".
What's the chance of getting a collision for data that is really different? Let's take for example the famousBirthday paradox. Suppose the coat check room assigned the hanger based on your birthday (month and day). How may coats before you run the risk of having two people turn in coats with the same birthday? After only 23 people, the likelihood is 50%. At 60 people, it goes up to 99%.
For this reason, IBM does not offer content-addressable storage. For non-erasable, non-rewriteable storage, the IBM System Storage DR550 requires the application to give each object a name, and that name is then used to storage the data, eliminating the possibility that data might accidently be thrown away.
It's safer that way.

Shakespeare wrote "What's in a name? That which we call a rose by any other word would smell as sweet." This week my theme will be on names, naming convention, and how we access information on storage.
Take for example these two sentences:
The Bears beat New Orleans.
Chicago clobbered the Saints.
Though they appear very different, football fans who might have watched either or both of the two conference title games yesterday would quickly recognize that they refer to the same two teams and the same end-result.
I'll be traveling to Asia next week. While most people call me "Tony", my legal given name is "Anthony" which is what appears on my passport and other legal documents. Most English-speaking countries handle this fine, but it can be confusing in Japan or China, where "A. Pearson" doesn't match "T. Pearson".
In the US, our given and family names are referred to as our "first name" and our "last name", relating to their positional sequence. In Asia, family names come first, followed by their given names last. To help avoid confusion, we have started adopting the practice of putting the family name in ALL CAPITAL LETTERS, so I would "Tony PEARSON" while my colleague may be "WONG Francis".
In Japanese, "Mr. JONES" would be "Jones-san". However, Pearson-san is such a toungue-twister, that most just say "Tony-san" which is fine with me. I have been called "Mr. Tony" in a variety of countries, perfectly acceptable.
You can call me anything you like, just don't call me late for dinner.

Wrapping up my week's theme of "diversity", with posts on a diverse set of topics,today I will suggest ways to spendyour time while you are walking 10,000 steps per day, as recommended by the authorsof the book "You: On a Diet"
(If you thought this was about the 10,000 steps it might take to implement a storage solution, you should switch over to IBM as your storage vendor. For example, the DS3200 and DS3400 can beimplemented in as little as SIX steps. That's pretty cool.)
Blogs like Lifehacker are an excellent resource for neat littletips and tricks to help you throughout your day, like how to use your iPod, cell phone or computer better, for example. These suggestions are based on the idea that you can walk your 10,000 steps with access to an iPod and cell phone.
- Learning a language
- ... or refreshing yourself on a language you might not have spoken in a while. In addition to formal audio-based lessons from Pimsleur, there are podcasts you can get for various languages. In preparation for my upcoming trip to Japan and China, I have been listening to JapanesePod101.com and ChinesePod.com which have quick lessons that complement the formal training.This Lifehacker postindicates there are similar ones for French, Spanish, Italian, and Brazillian Portuguese.
- Practicing your presentation
- Walking while practicing your 30-60 minute presentation would be good exercise.MicroPersuasion explains how to turn your iPod into the ultimate PowerPoint accessory, and this article in PlayListmag.com providesthe steps to get a PowerPoint presentation onto your iPod. I did this, and the slides are found underPhotos->Photo Library. The images are small, but heck, they are your charts and you should recognize themwell enough to remind yourself what to say on each slide.Also, I am able to record my practice sessions using MP3 Recorder and listen as I page through each slide. (In theory, you can use your iPod to present your slides to your audience, plugging the iPod directly into the laptop projector, instead of a laptop, using cables available at your local Apple store, and use the iPod controls as your forward/backward remote.)
- Working your To-Do list
- You can download your to-do list to your iPod. I use BackPackIt from 37 Signals. You can sign up for a free account, or upgrade to a paid account, and have anamazingly simple browser-based tool to develop your to-do lists, one for each project or aspect of your life. Oncedone, the list can be emailed to you as plain text. Enable your iPod as an "external disk drive" and copy this text file to your NOTES directory on the iPod drive. Voila! You can now read your to-do list! (I could also send it to my cell phone, using firstname.lastname@example.org, but I find the iPod easier to read and navigate)
Think of something to add? Send an email from your cell phone. With BackPackit, I can send an email that will directly add my text as a note or todo list item. On my phone, this is simply sending a text message to "500" with text like:
"email@example.com todo # buy bread".The hash mark (#) separates the subject line from the body of the email, and this is how Backpackit knows its a todo item or a note. If you pre-program the huge email address in advance on your phone, then it isn't as bad as it looks. It will be on your packpackit page the next time you log in.
Well, that's three suggestions. The next time you complain that there is no time to walk, you now have no excuse.

Next week I am "briefing" a client on a variety of topics, everything from our overall strategy, to our DS4000 disk systems, LTO tape, the DR550, and storage virtualization. A lot to cover, and they only gave me 60 minutes!
The challenge is not gathering the material, as it is shrinking it down to cover all the key points into a fluid story. Which reminds me of a saying we have inside IBM: "Develop with prose, Market with poetry." When I was in development, I had to write some huge specifications. Now that I am in marketing, the fewer words the better. In looking to see if this saying was a modified version of a famous quote from someone else, I encountered this interesting quote below. John Windsor of YouBlog might argue this could apply to most marketing attempts just as easily as most poetry.
Most people ignore most poetry
most poetry ignores most people.

Roger over at Creative Think asks ifChip Heath is the Next Malcolm Gladwell?, relating to a book called "Made to Stick". I just started reading this book yesterday, but it starts out with how some stories are more memorable than others. Some just "stick" in your head, like songs, and others are quickly forgotten.
I tell a lot of stories, some stick, some don't. For example, I had read in a Barnes and Noble flyer a description of a book that interested me. I went to the store, but had forgotten to bring the flyer with me. When the person at the help desk offered to help me find it on their computer system, I realized that I could not remember the author, the title nor the publisher. The only thing I could remember was that it was a dark green book. It was actually a collection of short stories that were all 55 words in length, all winners of a 55-word story contest. She then took out the flyer itself, and we found it easily from there. She asked why I only remembered that it was green, and I told her: "Because I collect green books."
I am amazed that the writers could cram a setting, characters, plot and resolution into only 55 words, and then I saw Anecdote's post Let's Be Brief which talks about the latest 6-word story contest, inspired by Hemmingway’s shortest story, which was only six words long.
Now that's brief!

Today, January 16, IBM launches its latest disk system, the DS3000 series.
There are actually three products in the DS3000 series:
The DS3200 is a 2U high, 12 drive system that attaches to servers via 3Gbps Serial Attach (SAS) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are theDS3200 specifications.
The DS3400 is a 2U high, 12 drive system that attaches to servers via 4Gbps Fibre Channel (FC) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are the DS3400 specifications.
The EXP3000 is a 2U high, 12 drive expansion drawer. It was announced back in August 2006, but is part of theoverall DS3000 series. It can be used directly with servers, but is also designed to be attached to the back of the DS3200 or DS3400 to increase capacity.Here are the EXP3000 specifications.
With this announcement, IBM provides entry-level storage at the "less-than-$5000" price point, withsupport for intermix of 10K and 15K RPM drives, and scalable up to 14.4 TB capacity.This would be ideal storage for HP, Dell, IBM System x and BladeCenter servers.

Today, in the US, is Martin Luther King day
. There is a good post about this by Seth Godin
.Dr. King had a vision for the future, and is most remembered by his speech that began: "I have a dream..."
IBM also has a vision for the future, and like Martin Luther King's speech, is startingto enable change. Last February 2006, IBM launched "Information on Demand", a visionthat involves bringing together our hardware, software, and services.
The impact has not gone unnoticed. Barron's featured IBM in an article titled "The New IBM".
I suspect bloggers helped get the word out. Here's a graph fromYahoo! Financeshowing the IBM stock price over the pastsix months. This blog started in September, when stock was in the low 80's, and now it is in thehigh 90's. I can't take all the credit, of course, as there are now over 3000 IBMers blogging, either inside thecompany, or externally to the rest of the world.
And the future continues to look bright.Greg over at IBMeye feels thatIBM stock poised for anotherstrong year.
If the analysts are right, 2007 is going to be a good year!

Continuing on my theme of storage area networking, today I thought I would coverthe concept of convergence. This is the notion of disparate things that come together.
Convergence plays a big role in Apple's new iPhone.ExpatJane has a nicecollection of news articles.Gizmodo has a two part hands-on experience of the iPhone hereand here. Seth Godin opines that theiPhone is not for everyone.
I would fall into the "not for me" category, at least at this time. The iPhone is GSM-capable phone with the ability to store 4GB or 8GB of music, photos and video, and has incorporated a 2 megapixel camera. Currently, I have separate components:
- A cell phone that is GSM plus CDMA, with features like "speakerphone" which I use quite a lot, but NO camera.
- A 7 megapixel camera, also very small, with removable memory cards.
- A 60GB iPod, with music and photos. My model is older and doesn't handle videos.
Since I visit government agencies, research and development labs, and other places that don't allow cameras, I have to either chose a cell phone that does not have camera capability in it, or have a camera phone that I leave behind in the car or at the front desk. I have chosen to get cell phones with NO camera. So, NOT having a camera is a primary feature I look for, but this is getting harder and harder these days. I don't know if Apple plans to have a non-camera version of their iPhone, but that would be a deal-breaker for me.
I do carry a separate camera, and where it is permissible, use it separately. This is especially useful if you do a lot of whiteboard or flipchart presentations, and want to capture what you have written for later. (For a great example of how effectively whiteboards can be used, check out these videos from UPS.)A picture is worth a thousand words, and is easier to convey an idea with pictures, especially in countries that may not speak English. Last month, I got a 7 megapixel camera to replace my 5 megapixel. For my work, 2 megapixel as found in the iPhone is not detailed enough.
As for my iPod, I enjoy that I can carry 60GB of music and photos. When I go on vacations, I can bring my camera and iPod, and connect the two, transferring and viewing the pictures that I take. I can easily free up 5-10 GB of space on my iPod for photos in preparation for a trip, then replace that with music when I am back at home. I also use my iPod as a remote disk drive for my laptop on business trips. Again, the 4GB and 8GB may not be enough for what I need.
Printers were never converged into Personal Computers, but they did have their own convergence. I have a multi-function printer/scanner/fax machine. I used to have separate printer, scanner and fax machines, but now the technology is so inexpensive that it got all combined into one solution.
The same is happening for Storage Area Networking gear.
- Thanks to Fibre Channel, switches and directors can handle both SCSI commands (FCP) and CCW commands (FICON). This allows the mainframe and distrbuted systems to converge their traffic onto a single network, and is less expensive than trying to maintain one network for the mainframes, and another for the distributed platforms.
- On the SCSI side, there are now switches that let you have pluggable ports of different flavors. For example, you can have some ports be Fibre Channel to receive FCP, and other ports to be Ethernet to carry iSCSI. iSCSI is a protocol co-developed between IBM and Cisco to carry SCSI commands over Ethernet. Since most computers already have Ethernet "network interface cards" and most buildings are already wired with an Ethernet infrastructure, this provides a less expensive alternative to Fibre Channel.
- Routers, and combination Router/Switches, can send all the FCP/FICON/iSCSI traffic over various long distances to remote data centers, using either iFCP or FCIP protocols. This is a less expensive alternative to dropping your own private "dark fiber" between the two locations, which often involves negotiating access rights to dig trenches through other people's property.
Which brings me back to Apple's iPhone. One device can make calls, watch video, and download webpages all because the networks have converged into sending all data in "packets". The network just routes packets from one place to another. It doesn't care that a packet is a voice packet, a video packet or a webpage packet. It doesn't matter.
This convergence then lets the convenience of a handheld device serve as the conduit for doing business, potentially replacing the credit card.IBM helped Visa and Nokia join forces to use cell phones as wallets. According to the article...
"Users can pay for groceries and other purchases by swiping a phone over a reader that electronically communicates with a microchip on the phone. Phone owners confirm the purchase with the push of a button and the deal is complete.
The platform is the result of many years of trials around the world and will enable mobile contactless payments, remote payments, person-to-person payments, and mobile coupons."
Now that's convergence I can get excited about!

Continuing on my theme of storage area networking, today I thought I would coverstorage networking at home.
Before the PC, corporate end-users had dumb terminals (displays) connected to mainframes (servers) thatwere then connected to external disk and tape (storage devices). This was all done with direct cable connections,then later through networks. The PC solved this by putting the display, server and storage into one unit, makingit more accessible to smaller businesses and individuals.
Many years ago, Microsoft started out with the vision "A PC on every desktop".The primary reason we even have networks is while everyone might have had their own PC, not everyone had their own printer. (Printers used to be part of IBM's storage division, which we explained as "storage on PAPER"!)Maybe if Microsoft's vision was "A PC and printer on every desktop", history might have turned up different.
Let's take a look at Apple's latest offerings shown at MacWorld 2007 in San Francisco, as well as how rivals battle for connected world at the Consumer Electronics Show (CES) 2007 in Las Vegas.Blogger Wax Banks argues that these announcements mean"the era of the personal computer is coming to an end".
Disclaimer: IBM has close business relationships with both Apple and Microsoft and others,providing the chips inside some of their products. I discuss them here not only becauseI am trying to get you to buy their products, and let IBM benefit indirectly from their success, but because they are newsworthy, and relevant to the topic at hand.
My take on all this...
- MacWorld 2007
- Apple CEO Steve Jobs presented the Apple TV. You can watch the MacWorld 2007 keynote presentation, orsee Zayne Humphrey's summary in a series of photos, or read Glenn Wolsey's take.
The "Apple TV" is not a TV at all, but rather a server, one that lets your television (your dumb terminal)access the video, audio and photos stored on your Mac or iPod (the storage device), all through a home network.(Sound familiar?)
Apple changed their name from "Apple Computer, Inc." to just "Apple, Inc." to signal a subtle but significant change,namely, that they want to be invited to next year's Consumer Electronics Show!Seeking Alpha offersNine Ways Apple Changed the Face of Consumer Electronics.Uber-blogger Steve Rubel weighs in on why the iPhone is a game changer, but the Apple TV is not.
- Consumer Electronics Show (CES) 2007
- Mr. Wargo, director of industry analysis at the Consumer Electronics Association, the organiser of CES, said: "One of the other major themes of this year is the services and content that feed the networked home."
Bill Gates from Microsoft gave the keynote, and this is probably his last appearance, as he is retiring in 2008,as we are reminded by thisfunny video, to move on to bigger, and better things. It is perhaps fitting that his retirement aligns with the end of the era for the PC.
Microsoft unveiled their Microsoft Windows Home Server, again a server that connects your television (dumb terminal) with your PC or Zune (storage device)all through your home network. (Sound familiar, again?)
Whereas Apple above pretty much shunned the gaming community, Microsoft embraced it with their internet-enabled Xbox360.Microsoft sold 10.4 million of these last year, which was 400 million more than they projected.
Our SAN technology partner Cisco wants to get in on this "home networking craze", as written about inInfoWorld andCnet.
the consumer electronics industry is taking clues from IBM's mainframe business. Not the first time this has happened, and probably not the last.
I already access photos and audio with my Tivo, from both my Mac AND my PC,so not much new here for me. Getting my home network connected was one of mytech highlights of 2006 and organizing my audio content was done withILM for my iPod.
Bypassing the PC, by being able to have your television, handheld or phone access data directly will greatlyincrease the demand for storage from businesses that provide information and content, and for storage networking technology in the home. It will be interesting how this all plays out in 2007.

Continuing this week's theme on Storage Area Networks, today I thought I would talkabout the various terms we use for our equipment.
One area of confusion are the adjectives "entry-level", "midrange" and "enterprise-class".What do these mean? Well, as in the case of disk and tape, these three are all relative terms that are a combination of "small, medium, large" as well as "good, better, best".
- Entry-level switches are typically only a maximum of 8-16 ports.Ports can connect the switch to a server, a storage device, or another switch.These are sometimes called "edge" switches, as they might be found in the mostremote sections of an office campus, remote branches, or other isolated areasoutside the primary data center.
- Midrange switches typically have a maximum of 32-64 ports.More ports on a single switch means fewer switches (and fewer cables) to manage.
- These are called "directors" to distinguish them from entry-level and midrange offerings.Directors have a maximum of 140-528 ports, and because so many devices or switches can beconnected to them, they need to be extremely reliable. Directors are designed for 24x7operation, with the ability to make most upgrades and configuration changes while the boxis running (often referred to as "non-disruptive upgrades"). Availability is typically better than "five nines", or 99.999 percent, which means that the box will be up 99.999 percent of the time, or conversely, will be down lessthan 5 minutes per year.
If you are asking yourself "which size is right for my company?" or "is my company big enoughfor a director?" you are asking the wrong questions! Instead, determine a SAN configurationthat meets your workload, and then decide the components for that design.
McData coined a phrase called "core/edge" design that is considered today as "Best Practice" throughout the industry.A good write-up can be found here at SearchStorage.com. Basically, you put your big beefy "core" directors in the center of the room, and then surround it with midrange switches, that then these connect to "edge" switches, that then connect to the servers and storage near them. As you grow, this design can easilyscale to grow with you.
So, if you need help implementing a SAN for the first time, or upgrading the one you have,call IBM, we can help!

Last week, Paul Weinberg of eChannelLine.com asks Is this the year of the SAN (again)?
So, I thought this week I would cover my thoughts and opinions on storage networking. We oftenfocus on servers or storage devices, and forget that the network in between is an entire worldon itself.
I believe Mr. Weinberg is basing this on the idea that in 2007, over 50 percent of disk will beattached over SAN, edging out the alternative: Direct Attached Storage (DAS). But perhaps 50 percentis the wrong number to focus on. In 2007, The United Nations estimates thatcities will surpass rural areas, with just over 50 percent of theworld's population. Does that make this the "Year of the City"? Of course not.
Instead, I prefer to use the methodology that Malcolm Gladwell uses in his book, The Tipping Point.(I have read this book and highly recommend it!)Gladwell indicates that the tipping point happens at the start of the epidemic, not when it is half over.Isn't it better to celebrate the sweet 16 debutante ball when young ladies have completed their years of training and preparation, and are ready to be introduced to the rest of the world, rather than after they are thirty-something, married with children.
Let's explore some of the history. Stuart Kendric has a nice 7-page summary on theHistory & Plumbing of SANs.
IBM announced the first SAN technology calledEnterprise Systems Connection (ESCON) way back in September 1990. This allowed multiplemainframe servers to connect to multiple storage systems over equipment called "ESCON Directors" that directedtraffic from point A to point B. Before this, mainframes sent "ChannelCommand Words" or CCWs, across parallel "bus and tag" copper cables. ESCON was serial overfiber optic wiring. SANs solved two problems: first, it reduced the "rat's nest" of cables between many serversand many storage systems, and second, it extended the distance between server and storage device.
For distributed systems running UNIX or Windows, the CCW-equivalent over parallel cables was called Small ComputerSystem Interface (SCSI). The SCSI command had over 1000 command words, so for its Advanced Technology (AT) personal computers (PC AT), IBM introduced a subset of SCSI commands called ATA (Advanced Technology Attachment). ATA drives supportedfewer commands, ran at slower speeds, and were manufactured with a less rigorous process. Today ATA drives are about 55 percent the cost per MB as comparable SCSI drives.
Anyone who has ever opened their PC and found flat ribbon cable with eight or sixteen wires in parallel, can understand that the same issues applied externally. Parallel technologies arelimited to distance and speed, as all the bits have to arrive at the end of the wire at approximately thesame time. Direct attach schemes with every server attaches directly to every storage device were also problematic.Imagine 100 servers connected to 100 storage devices, that would be 10,000 wires!
So, a new technology standard was developed, called Fibre Channel, ratified in 1994.The spelling of "Fibre" was intentionally made different than "Fiber" on purpose. "Fibre" is a protocol thatcan travel over copper or glass wires. "Fiber" represents the glass wiring itself.
Fibre Channel is amazingly versatile. For today's Linux, UNIX and Windows servers, it can carry SCSI commands, and the combination of SCSI over FC is called Fibre Channel Protocol (FCP). For the mainframe servers, it can carry CCW commands. Running CCW over Fibre Channel is called FICON. This convergence allows mainframes and distributed systems to share a common Fibre Channel network, using the same set of switches and directors.
We saw the use of SANs explode in the marketplace over the past 10 years, and then cool down with a series of mergers and acquisitions. Last year, Brocade announced it was acquiring rival McData, so we will be down to two major players, Cisco and Brocade.
So, IMHO, I think we are well past the "Year of the SAN".

Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that people don't always think about on a personal level, that is to hone your tools and skills.
A long time ago, I used to be a regular speaker at the SHARE user group conference. One of the most attended sessions was Sam Golob presenting the latest CBT Tape set of tools. Over time, this large collection of "mainframe shareware" was handed out on 3480 tape cartridges, then on CDs, and finally made downloadable off the web.Sam's main point, which I remember to this day, was that everyone who has a job should figure out what tools they use, keep those tools functioning properly, and learn to use them well.
Later, I took some cooking classes at a culinary school. Among other things, we learned:
- A sharp knife is safer and easier to use than a dull one, resulting in fewer accidents
- Knowing what you are doing is the difference between food that is "simply awful" to that which is "awfully simple" to prepare.
- A well trained chef can prepare most meals with just a sharp knife and wooden spoon.
This last point hits close to home, as many people like me have too many tools that they do not use often enough to know how to use them well. Do I really need my strawberry corer, garlic press, or a tray designed for the storage and delivery of deviled eggs?
The same could be said about software tools. What tools do you use in your job? Do you feel you know how to take full advantage of their power and capabilities?If you develop software, do you know all the features for your debugging tools? If you develop advertising or marketing materials, do you know all the features of your photo or video editing software? If you manage storage in a data center, do you know all the tools for managing your storage area network (SAN), disk systems, tape libraries, and reporting tools to identify all of your files and databases across your entire IT environment?I would not be surprised if you could replace a whole mess of tools with just one, such as the IBM TotalStorage Productivity Center.
For me, I resolve to learn how to better use Lotus Notes e-mail client, and perhaps the new Office 2007.

Wrapping up this week's theme of New Year's Resolutions for the data center, the New York Times argues we should go easy on the resolutions
, so I'll conclude with reducing stress. Lighten up! Relax, and try not to take your job so seriously.
(I know you're probably thinking, "That's easy for you to say, Mr. paid-to-play-golf-with-clients big-shot executive, but what about the rest of us?" or perhaps "I can't do that! My job is so important that if I didn't take it so seriously, my company would go bankrupt, my industry would falter, and global economies will collapse!" I can understand. Over 70 percent of all of the world's business transactions travels through, or sits on, IBM equipment, so you can imagine how stressful my past 20 years have been. Bear with me, read on, and hopefully you might benefit from my past experiences.)
- Laugh out loud
- Everytime someone laughs out loud at the office here in Tucson, everyone else within earshot stops what they are doing and rushes over to see what is so funny. Likewise, everytime it rains during normal working hours, people stop what they are doing, and run to the windows to see what water coming out of the sky looks like. Do you work in a "dry" climate, where laughter, like rain, is a rare occurrence?
Recognizing the benefits of laughter on reducing stress and improving health, my friends and I started theTucson Laughter Club back in 2004. There are hundreds of laughter clubs across the United States and the rest of the world, sometimes referred to as "Laughter Yoga" groups. Those of you readers in Tucson are welcome to join us, our next meeting is January 13.
Look to see if there is one near you, or start your own. Until then, laugh while you watch this funny storage-related video from the folks over at Sun StorageTek, or this one from Kodak.
- Every laughter club meeting starts out with some breathing exercises. If you feel stressed, try this simple2-minute relaxation technique.
- I'm not just talking about stretching our muscles here.
- The next time you tell the story, stretch the truth a little, aim for 70 percent truth, 30 percent embellishment.
- The next time you are making plans for lunch or dinner, stretch yourself out of your comfort zone and try something new and different, new restaurant, or different type of cuisine.
- The next time you get called by a phone solicitor or telemarket, stretch out the conversation, have fun with it, ask them what they are wearing, and share with them all the successes and problems you have at work, until THEY hang up first.
- The next time you are throwing a party, stretch your invite list to include someone you normally wouldn't invite, perhaps a neighbor or co-worker.
- The next time someone insists you make a list,stretch the process out, to give you more time to drink their expensive wine.
- When you hear the phrase Work/Life Balance, do you think to yourself, "I would settle for Work/Sleep Balance!"You're not alone. The National Sleep Foundation reports that most Americans don't get enough sleep, which can causevarious health problems.
So get plenty of sleep at home, before you get fired forsleeping on the job.
- Get along with others
- Peace on earth starts one relationship at a time.I found this amusing article on Wired, discussion the Top Blogfights of 2006.Can't we all get along? I stopped two blog-fights in 2006, just by pointing to the facts, and setting the record straight.
If there is someone you are not getting along with at work, fix it. Sooner, rather than later. Here are tips to be more assertive.
- Listen to Music
- Can you listen to music where you work? Listening to music has been shownto help reduce stress.I've got my Thinkpad T60 laptop connected to my wireless bluetooth headset, so I can listen to relaxing music without disturbing anyone else, and not be "tethered" to my system with traditional headphone wires.
In her book, "Life Hacker: 88 tech tricks to turbocharge your day", Gina Trapani suggestsPink noise. I prefer"The Quiet Earth", an internet radio station on Live365.
So, relax and enjoy your weekend. And remember, when you get back to the office on Monday, its only ones and zeros.

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.

Happy New Year!
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.
If you don't know where to start with ILM, certainly IBM can point you to the right solutions,best practices, techniques, and whitepaper.
