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 email@example.com, 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:
"firstname.lastname@example.org 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.
