ILM for my iPod

Body

Last week, Steve Jobs demonstrated the latest evidence that theinmates are running the asylum over at Apple.

I wasn't at the event, but thought it would be good to explain some basic concepts ofInformation Lifecycle Management (ILM),using the files on my iPod as an example. (Disclosure: IBM makes the technology inside many of Apple's computers, and so IBMers get to buy Appleproducts at employee prices. I own a Mac Mini based on IBM's POWER4 processor, and an iPod Photo 60GB model).

I have 20,000 MP3 music files, representing 106GB of data. This fits nicely on my 250GB external disk system attached to my Mac Mini, but won't all fit on my little 60GB iPod. I needed a way to decide what music I keep on bothmy iPod and Mac Mini, and which I keep only on my Mac Mini. When I am traveling, I am able to listen only to the musicin the first group, but when I am at home, I am able to listen to all my music in both groups.(Another disclosure: I use my Tivo connected to my LAN to play all my MP3 music through my home stereo system.I had my entire house wired with Cat5 to make this possible.)

Apple's iTunes software lets me decide which MP3 files are copied to my iPod using "playlists". A playlist is a list of songs. Fixed playlists are created manually, each song copied to its list in a specific order. Smart playlists are createdautomatically, via policy. I give it the criteria, and it finds the songs for me. If I import a new music CD,none of the songs will be added to any fixed playlists, but could be added to my smart playlists if I set the policiescorrectly. Apple iTunes supports both "include" and "exclude" methodologies.

I use primarily smart playlists, based on genre and rating. I have tried to keep the number of genre down to a small manageable list:

• Ambient
• Rhythm & Blues
• Hip Hop
• Dance
• Pop
• Rock

Of course, what I have for genre may not match what's in theGracenote database, so I sometimes have to makeupdates to match my convention. I've picked these based on my different "applications" for my music. For example, I listen to Ambient music to help me fall asleep on airplanes, but Rock when I exercise at the gym.

Next, I use the ratings from one to five stars. The advantage to the rating is that I can change them on-the-fly directly on my iPod. All other "metadata" has to be entered only from the keyboard of my Mac Mini.

*	Files for Mac Mini only, not copied to my iPod
**	Non-mix, copied to my iPod, but typically spoken words, such as language lessons
***	Mix, music to include in my music mixes
****	Keep on my iPod, but re-evaluate
*****	My favorites

So, I have five smart playlists, "One Star", "Two Stars", etc. for each rating, and have decidedto keep only the 2, 3, 4 and 5 star songs on my iPod, by simply putting check marks on those playlists to copythem over. I have about 50 songs with 5 stars, and 8000 with 3 stars, and the rest in the other categories,leaving me a few GB to spare.

I also have playlists for each genre, "Rock mix", "Pop Mix", "Ambient Mix", etc. where I have selected thosethat match the genre, AND have 3, 4 or 5 stars. In this manner, I can listen to a mix. If I find a song mis-classified for that genre, I change it to four stars, which serves as myreminder to re-evaluate when I am back at home on my Mac Mini. If I don't want a song in my mix, I just lowerit to 2 stars. I want it off my iPod altogether, I lower it to one star.

This method is simple enough, and allows me to enjoy my music right away, and more effectively, without having to wait for completely finishing my classification process.

Next week, I'm traveling to Africa (purely vacation, not related to my job, my senator, or myinvolvement in anycharitable organizations). My Canon camera has only a 1GB IBM Microdrive, but I am able to offloadmy pictures to my iPod, connected via USB cable, and review the pictures on the little 2-inch screen. By simply "unchecking" my 2-star and 3-starplaylists, and checking only those mixes I plan to take with me, I was able to clear 17GB of space, plenty ofroom for all my photos of elephants and giraffes, but still plenty of music to listen to. Thanks to my simple methodology, I was able to do this with minimal effort, and willhave no problem putting all my music back when I return.

When evaluating an ILM process, many people are overwhelmed by their fear of the classification process, when in reality it doesn't have to be so complicated.

Is there an "iTunes" for the storage in your datacenter? Yes! It's called IBM TotalStorage Productivity Center. It can help you list and classify all the files in your IT environment,including files in your internal disks inside the servers, your NAS and SAN external disk systems, across both IBM and non-IBM hardware.It's a good thing to consider as part of your overall ILM strategy.
