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.
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.
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?)
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.
My take on all this...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.
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.
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.
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.
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.
I got an interesting email from a new blogger asking me for advice on how frequently to post entries.I am probably not the right person to ask, as I blog whenever a thought comes to mind that I think otherswould enjoy reading, and sometimes that means several times a day, and other times only a few per month.I actually have a day job, busy doing other things, and blogging is just now part of my general set of activities.My focus is quality not quantity.
With that in mind, I was delightfully surprised that this blog was ranked among theTop 10 Storage Blogs by Network World, which explains my recent spike in traffic.
I shared the news with my 72-year-old father, and he exclaimed "There are actually 10 or more blogsto cover the IT storage industry?" He couldn't understand why the world would read more than two or three. I personally track thirty-five of them, and I suspect there are hundredsothers out there. Of these, some blog quite regularly, while others do not, so I am in good company. Deni Connor, the author who selected these top 10, gave a nice general complement tothe entire list of blogs:
The blogs written by storage company executives can be surprisingly vendor-agnostic, though the analysts and consultants still tend to pull fewer punches.
And this was my goal as well, to enlighten and entertain, in a fair and balanced manner, that adds value to the blogosphere, rather than just repeat the IBM press releases of each day. If you are just looking for "announcements" there is an RSS feed for IBM System Storage you cansubscribe to.
Not surprisingly, two of the blog entries that Deni mentions are the ones I get the most comments on:
ILM for my iPod tried to explain Information Lifecycle Management (ILM) into laymen terms that everyone could understand. As an engineer-turned-marketeer, explaining technology and concepts into laymen terms is something I find myself doing a lot to help others grasp what is otherwise rather complex industry we are in. Not surprisingly, many IBMers were not aware they were eligible for discounts on Apple products like the iPod, and thanked me for pointing them to this.
Aperi is "Viagra" for SMI-S which has now become my infamous blog entry within the halls of IBM. I chose this term over "steroids" given the various scandals involving famous athletes that were going on at the time. To this day,if you search Google for "Tony Pearson" AND "Viagra" you get this blog entry at the top of the list. Oneco-worker overheard that I had "used Viagra" only to later find out they were referring to the fact that I "used Viagra as a metaphor in the title of a blog entry". And that was the real issue, not that I used the term in a popular vernacular that might not translate well into other languages, or that I failed to attribute this as a trademark that belonged to its respective manufacturer, but that it was in the title itself, and thus the URL became "aperi_is_viagra_for_smi" when published in newspapers and press releases. I have since learned to be more careful when phrasing the titles of my blog entries.
I began my year-end vacation today, but like exercising at the gym, I will try to keep up with my blogging over these next two weeks. Especially for those readers out there doing end-of-year storage infrastructure changes. This blog is for you.[Read More]
