I just got a series of videos made at last month's IBM Pulse 2009 conference.Rather than flood you with all of them all at once, I will post them all separately.
A few weeks ago, my Tivo(R) digital video recorder (DVR) died. All of my digital clocks in my house were flashing 12:00 so I suspect it wasa power strike while I was at the office. The only other item to die was the surge protector,and so it did what it was supposed to do, give up its own life to protect the rest of myequipment. Although somehow, it did not protect my Tivo.
I opened a problem ticket with Sony, and they sent me instructions on how to send itover to another state to get it repaired.Amusingly, the instructions included "Please make a backup of the drive contents beforesending the unit in for repair." Excuse me? How am I supposed to do that, exactly?
My model has only a single 80GB drive, and so my friend and I removed the drive and attachedit to one of our other systems to see if anything was salvageable. It failed every diagnostictest. There was just not enough to read to be usable elsewhere.
This is typical of many home systems. They are not designed for robust usage, high availability, nor any form of backup/recovery process. Some of the newer models havetwo drives in a RAID-1 mode configuration, but most have many single points of failure.
And certainly, it is not mission critical data. Life goes on without the last few episodesof Jack Bauer on "24", or the various Food Network shows that I recorded for items I planto bake some day. For the past few weeks, I have spent more time listening to the radioand reading books. Somehow, even though my television runs fine without my Tivo, watchingTV in "real time" just isn't the same.
I suspect that if you gave someone a method to do the backup, most would not bother to useit. People are now relying more and more heavily on their home-basedinformation storage systems, digital music, video and cherished photographs. Perhaps experiencing a "loss" will help them appreciate backup/recovery systems so much more than they do today.

March 31 is [World Backup Day]!
Recently, a client asked how to backup their IBM PureData System for Analytics devices. IBM had [acquired Netezza in November 2010], and later renamed their TwinFin devices as the IBM PureData for Analytics, powered by Netezza.
The [IBM PureData System for Analytics] is incredibly fast for performing deep, ad-hoc analytics. However, the people who use them are "data scientists", not backup experts.
Likewise, there are backup administrators who may not be familiar with the unique characteristics of this expert-integrated system to know what backup options are available.
As with the rest of the IBM PureSystems line, the IBM PureData System for Analytics (or, PDA for short) has a combination of servers, storage and switches inside.
In a full-frame PDA, there are two servers in Active/Passive mode, these coordinate activity to FPGA-based blade servers, which have parallel access to hundreds of disk drives, storing nearly 200 TB of compressed database data. A system can span up to four frames.
But what do you backup? And why? You don't need to worry about backing up the Linux operating system or NPS server code, that is considered firmware and if anything every got corrupted, IBM would help restore it for you. System-wide metadata, such as the host catalog and global users, groups, and permissions should be backed up periodically to protect against data corruption.
There are a number of reasons to backup your user databases:
The PDA has three backup formats. You can backup the entire user database in compressed format, backup individual tables in compressed format, or export to a text-format file.
Compressed format is faster, but can only be restored to the same PDA, or a PDA that has the same or higher level of NPS firmware. The text-format is slower, but can be used to restore to lower levels of NPS firmware, or to other database systems.
There are basically two methods to backup your PDA. The first is called the "Filesystem" method. Basically, you can attach an external storage device to the NPS server, and use the built-in command line interface (CLI) to store the backups onto its file system.
You may find that your databases are so large, they will exceed the limits of the filesystem on the external storage device. For SAN or NAS deployments, I recommend the IBM Storwize V7000 Unified with IBM General Parallel File System (GPFS). However, if you are using something else, you may need to use the "nz_backup" scripts provided which split up the backup images into smaller pieces that most other filesystems can handle.
The PDA comes with 10GbE Ethernet ports that you can attach a NAS storage device over a Local Area Network (LAN), or add Fibre Channel Protocol (FCP) ports and connect over a Storage Area Network (SAN). To keep things simple, I will refer to whichever network you decide as the "Backup Network" in the drawings.
The second method for backup is called the "External Backup Software" method. As you have probably guessed, it involves sending the backups to a supported software product like IBM Tivoli Storage Manager (or, TSM for short).
In this case, the PDA acts as a client node, similar to a laptop, desktop, or application server with internal disk. Backup data is sent over the LAN to the designated TSM server, and the TSM server in turn writes over the SAN to its storage hierarchy of disk, virtual tape and/or physical tape resources.
Backups can be done by command "on demand", or automated on a schedule. For the /nz/data directory, direct the nzhostbackup command to send the backup copy to local disk, then use TSM's dsmc archive command to transfer this backup copy to the TSM server.
For nzbackup with the users or db parameters, you can send the data directly to the appropriate TSM server by specifying the connector and connectorArgs parameters.
To reduce traffic on the TSM Server, an intermediary "TSM Proxy Node" can be put in between. In this case, the PDA sends the backup to the Proxy Node, the Proxy Node uses a "LAN Free Storage Agent" to send the backups directly to the virtual tape and/or physical tape, and then notifies the TSM Server to updates its system catalog to record which tape holds these new backups.
Another configuration involves installing the TSM LAN Free storage agent directly on the PDA. While this will require FCP ports to be added and consume more CPU resources on the NPS server, it eliminates most of the LAN traffic, allowing the PDA to send its backups directly to virtual or physical tape.
To learn more about this, see my full presentation [Backup Options: IBM PureData System for Analytics, powered by Netezza] on the IBM Expert Network powered by SlideShare, or attend the upcoming [IBM Edge 2014] conference in Las Vegas, May 19-23. I will be there!

Well, it's that Back-To-School time again! Mo's thirteen-year-old reluctantly enters the eight grade, still upset the summer ended so abruptly. Richard's nephew returns to the University of Arizona for another year. Natalie has chosen to move to Phoenix and pursue a post-grad degree at Arizona State University. They all have two things in common, they all want a new computer, and they are all on a budget.
Fellow blogger Bob Sutor (IBM) pointed me to an excellent article on [How to Build Your Own $200 PC], which reminded me of the [XS server I built] for my 2008 Google Summer of Code project with the One Laptop per Child organization. Now that the project is over, I have upgraded it to Ubuntu Desktop 10.04 LTS, known as Lucid Lynx. Building your own PC with your student is a great learning experience in itself. Of course, this is just the computer itself, you still need to buy the keyboard, mouse and video monitor separately, if you don't already have these.
If you are not interested in building a PC from scratch, consider taking an old Windows-based PC and installing Linux to bring it new life. Many of the older PCs don't have enough processor or memory to run Windows Vista or the latest Windows 7, but they will all run Linux.
(If you think your old system has resale value, try checking out the ["trade-in estimator"] at the BestBuy website to straighten out your misperception. However, if you do decide to sell your system, consider replacing the disk drive with a fresh empty one, or wipe the old drive clean with one of the many free Linux utilities. Jason Striegel on Engadget has a nice [HOWTO Erase your old hard disk drive] article. If you don't have your original manufacturer's Windows installation discs, installing Linux instead may help keep you out of legal hot water.)
Depending on what your school projects require, you want to make sure that you can use a printer or scanner with your Linux system. Don't buy a printer unless it is supported by Linux. The Linux Foundation maintains a [Printer Compatability database]. Printing was one of the first things I got working for my Linux-based OLPC laptop, which I documented in my December 2007 post [Printing on XO Laptop with CUPS and LPR] and got a surprising following over at [OLPC News].
To reduce paper, many schools are having students email their assignments, or use Cloud Computing services like Google Docs. Both the University of Arizona and Arizona State University use Google Docs, and the students I have talked with love the idea. Whether they use a Mac, Linux or Windows PC, all students can access Google Docs through their browser. An alternative to Google Docs is Windows Live Skydrive, which has the option to upload and edit the latest Office format documents from the Firefox browser on Linux. Both offer you the option to upload GBs of files, which could be helpful transferring data from an old PC to a new one.
Lastly, there are many free video games for Linux, for when you need to take a break from all that studying. Ever since IBM's [36-page Global Innovation Outlook 2.0] study showed that playing video games made you a better business leader, I have been encouraging all students that I tutor or mentor that playing games is a more valuable use of your time than watching television. IBM considers video games the [future of learning]. Even the [Violent Video Games are Good for Kids]. It is no wonder that IBM provides the technology that runs all the major game platforms, including Microsoft Xbox360, Nintendo Wii and Sony PlayStation.
(FTC disclosure: I work for IBM. IBM has working relationships with Apple, Google, Microsoft, Nintendo and Sony. I use both Google Docs and Microsoft Live Skydrive for personal use, and base my recommendations purely on my own experience. I own stock in IBM, Google and Apple. I have friends and family that work at Microsoft. I own an Apple Mac Mini and Sony PlayStation. I was a Linux developer earlier in my IBM career. IBM considers Linux a strategic operating system for both personal and professional use. IBM has selected Firefox as its standard browser internally for all employees. I run Linux both at home and at the office. I graduated from the University of Arizona, and have friends who either work or take classes there, as well as at Arizona State University.)
Linux skills are marketable and growing more in demand. Linux is used in everything from cellphones to mainframes, as well as many IBM storage devices such as the IBM SAN Volume Controller, XIV and ProtecTIER data deduplication solution. In addition to writing term papers, spreadsheets and presentations with OpenOffice, your Linux PC can help you learn programming skills, web design, and database administration.
To all the students in my life, I wish you all good things in the upcoming school year!

For those of you worried about my mysterious absence on the blogosphere, I am getting better. Sorry for not posting much lately, I have had more serious issues to worry about. I am awaiting results on whether I have Dengue fever from Brazil, Avian flu from Thailand, Malaria from Kenya, or perhaps it is just food poisoning from the otherwise fabulous French cuisine I ate last week in the South Pacific. Well, I am back in town for a while, and hopefully will recover to full health, and have some time to reflect my thoughts on storage topics.
Speaking of which, a lot has happened while I was out. Let's take a quick look.
This week I was in Palm Springs in meetings with clients, prospects, business partners and IBM sales reps.
Tuesday consisted of "outdoor meetings", but the high winds caused some people to arrive late, and others to land in the various sand traps and water hazards. A "welcome reception" event allowed everyone to socialize and get to know the IBM experts and executives. Two of my colleagues, Mike Stanek and Dave Wyatt, were with me also in Australia last week, and so the three of us were discussing recovery from jet lag.
Wednesday was organized as a main tent event, where everyone met into one large room to hear our strategy,latest set of offerings, and customer testimonials. This was done indoors, of course, which was a good thing as the winds were now gusting up to 50 miles per hour, knocking over windmills and making the local news.
Here's a quick sample from the testimonials:
The event got great reviews, and I look forward to the next one. Until then, enjoy the weekend!

I'm back. Thanks for all the comments.
For those who participated in Clark Hodge's "Where's Tony" contest,I was in Croatia, Bosnia and Herzogovina. There were optional side-tours to Montenegro and Slovenia, but I decided not to incur the added time and expense with those.
For those wondering where to go this Summer for vacation, I recommend Croatia. It is a beautiful country, with clean cities, good road conditions, and a calm Adriatic sea as we went from island to island.
And if you get to Mostar, don't let them talk you into jumping off the "old bridge". The water is terribly cold down there![Read More]
On August 8, Brocade announced its intent to acquire McData corporation. IBM will continue to sell both Brocade and McData networking gear, as the acquisition will not be finalized until January 2007.
Read more about it directly from brocade www.brocade.com
For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
You can read more about it www.ibm.com/storage/tape.
As an alumni of the University of Arizona, it is always good to see any of the Arizona schools try something new and innovative. This time, it was our arch-rivals atArizona State University (in Tempe, AZ, near Phoenix).
An article in InformationWeek reports that40,000 ASU Students Leap to Google Apps; University Pays Zero. The ASU president, Michael Crow, wants to make IT the primary driver in his ambitious "New American University" project.Last October, ASU became the first large institution to deploy Google Apps, a comprehensive suite of productivity applications that includes e-mail, search, calendars, instant messaging, and even word processing and spreadsheets.I've tried them out, they work, nothing fancy but certainly good enough for college homework assignments.
Already 40,000 students and faculty have switched their e-mail to Google, while keeping their asu.edu designation. (out of 65,000 student population, which Mr. Crow is trying to raise to 90,000 students!)
E-mail is a thorn in the side of storage administrators. Being "semi-structured" repositories, they cannot just delete or move files around, as there is context between notes and their attachments, that shouldn't be broken. E-mail systems are often the fastest growing consumer of storage for many organizations.
Switching from maintaining their own mail servers to Google is saving ASU $500,000 US dollars alone, not including the administrator labor savings. Again, some corporations might feel their e-mail is too "secret" to be outsourced like this, but for college students who spend all their creative talent posting things on MySpace and YouTube, and faculty who spend their careers TRYING to get published, they have nothing to hide from the rest of the world. It makes perfect sense.
Best of all, Google isn't charging ASU anything for this service. Google is able to cover the costs from advertising revenue instead. I can think of a lot of companies that might want to advertise to a demographic of "40,000 students who are mostly 18-25 years old and all live in or near Tempe, AZ".

I've been so busy with travel and transitioning to my new laptop that I finally now have a chance to catch my breath.
I saw this great article by Nathan Willis on how to [Spring Clean your Photo Collection]. Since I took over 1100 pictures on my last vacation down the Great River Road, this seemed like a good weekend project. For more about my vacation, see my posts [Eight States in Eight Days], and [More Like Seven States in Nine Days].
Fortunately, many "photo product" providers are connected to Flickr. For example, my publisher [<a href="http://www.lulu.com/">Lulu.com</a>] can access my Flickr photos to make photo-based coffee table books. As for my last eight years of memories that were lost, I will just have to treat it as if my house burned down. Rebuild and move on.

I have arrived safely to Istanbul, Turkey for the [Systems Technical University 2014] conference. The conference will feature experts from IBM Power Systems, IBM System x, IBM PureSystems, and IBM System Storage.
Here is the view from my hotel window. Up until the 19th century, this was open countryside. Around 1890, the Bomonti brothers from Switzerland set up a brewery, which was moved to this section of town in 1902, becoming the first Turkish brewery. In 1934, the brewery was nationalized and became the Istanbul Tekel Beer Factory. The Hilton Bomonti hotel where the conference is being held is named after these brothers.
Since this is my first time to Istanbul, and I did not have meetings until later in the afternoon for the conference, I decided to a bit of sightseeing.
(A special thanks to Gail Godbey of [Encounter Tours/Kaletours] who organized this entire tour of sightseeing for me on such short notice!)
The hippodrome was a stadium for horse and chariot racing, but now is just a square with a few obelisks. This one is the Thutmosis Obelisk from Egypt. The word hippodrome comes from the Greek hippos, meaning horse, and dromos, meaning path or way. Hippodromes were common features of Greek cities in the Hellenistic, Roman and Byzantine eras. My tour guide Erol Azor did a great job explaining everything.
My favorite stop of the day was the Blue Mosque, named after the blue tiles used on the dome. It is 43 meters high, making it one of the tallest mosques in the city. There are over 3,000 mosques here in Istanbul. In Turkish, this place is called Sultan Ahmet Camii after the Sultan Ahmet that had it built from 1609-1616. There are six minarets. The legend goes that the Sultan asked for a "gold" minaret, but the word for "gold" in Arabic sounds a lot the number six in Turkish, so that is why there are six of them.
Right next to the Blue Mosque is the Hagia Sofia, which was a Christian church first, then converted to a mosque, and now is a musuem. It was closed on Mondays, so all I could do was take pictures from the outside. Tulips are in full bloom throughout the city this month of April. If you notice, the minaret on the right is different color. Often, new sultans would add a minaret to an existing mosque, using whatever materials were available at the time. Kind of like adding a bedroom to an existing house.
Underneath the ground is the Basilica Cistern which held the drinking water for the city. The water came in on viaduct, and was kept underground. Today, it has a foot of water, and some fish, for people to admire the architecture employed.
Of course, no visit to Istanbul is complete without stopping at the Grand Bazaar. With over 4,000 tiny shops, it is a madhouse of gold and silver jewelry, blue jeans, leather goods, scarves, persian rugs, and antiques. Some places offered me free samples of Turkish delight, which are delicious cubes of flavored gelatin.
My day ended at the Topkapi palace. The word Topkapi is Turkish for "Cannon Gate", as this castle sits overlooking the peninsula and bosphorus strait that separates the Europe side from the Asian side of the city. Like the palace of Versaille in France, or Buckingham palace in England, the Topkapi palace was home to 36 sultans from 1299 to 1922.
You can spend hours here. There are beautiful gardens and various buildings surrounded by five kilometers of castle wall. Inside the buildings are displays of the family jewels, the clothes the sultans wore, their weapons, and religious relics.
It was good to get a flavor of the city, and a sense of the Turkish culture.
As a consultant, I am often asked to help design the architecture for the information infrastructure. A usefulanalogy to gather requirements and preferences is the difference between area rugs and wall-to-wall carpeting. Arearugs are not secured to the floor and cover only a portion of the floor area. Carpets are generally tacked or cemented to the floor, often with an underlay of cushion padding, stretched across the entire floor surface, out to all four walls of each room.
Each has its pros and cons, and often is a matter of preference. Some people like area rugs because they can choosea different style for each room, match the decor and color scheme of furniture, and use these to define each livingspace. Ever since paleolithic man put animal skins on the floor of their cave, people recognize that cold, hard andugly floors could be covered up with something soft and more attractive.Others prefer wall-to-wall carpeting because they want to walk around the house barefoot, have their young children crawl on their hands and knees, and give the entire house a unified look and feel. This is often an inexpensive option when compared against the cost of individual rugs.
IBM can help you design an information infrastructure that fits either approach.Read More]

Well, it's Tuesday, which means IBM Announcements!
We have both disk and tape related announcements today.
