It seems I have been on the road non-stop for the past nine weeks! On my flights, I often find myself sitting next to a young adult who is flying for the first time. Many of these young adults formed their fear of flying a decade ago, in their teenage years, during the terror attacks of September 11, 2001. Some are just now trying to face those fears.
(What does any of this have to do with storage? Actually, there are similar fears for enabling various storage efficiency functions like data deduplication, thin provisioning and compression, so work with me here!)
Flying from Seattle down to Los Angeles, I sat next to Michele (shown in the picture on the left). She was facing her fear of flying overseas by taking seven months off to visit Japan, China, Thailand, Laos, Ireland, England and various countries in continental Europe. Wow! She was joining up with her friend Brittney in Los Angeles, and the two will be travelling together. Since I had been to nearly every country she was planning to visit, I gave her a list of survival phrases and cultural guidance.
Flying from Los Angeles to Tucson, I sat next to Alex on his first day of flying adventures. He flew from Jacksonville, to Dallas, to Los Angeles, to finally Tucson to pick up his fiancée. He met her in Florida, but her father was re-assigned to Fort Huachuca Army Base near Tucson, Arizona. He kept in touch with his bride-to-be, and now faced his fear of flying to go pick her up and bring her back for the wedding. This was the first time he had been west of the Mississippi river.
On a short 18-minute flight from Tucson to Phoenix, I sat next to Rachel, a college student at the University of Arizona, on her way to visit her folks in Santa Ana, California. She immediately apologized to me for not wearing pants. What I mistook for bikini bottoms were actually stretchy exercise shorts she wears to play [Lacrosse]. She had sprained her ankle, then went [AMA] to wear high-heeled shoes on a girl's weekend to Las Vegas, only to trip and break her ankle completely. Her foot was in a cast, thus preventing her from driving her car, or, as it turned out, wear any pants.
- Returning from a briefing in Poughkeepsie, on the short flight from Stewart Airport to Philadelphia, I sat next to Krista (shown in the picture on the right), who formerly was a [Bacardi Girl], but now decided she wants to do something more meaningful in her life than handing out prizes and free samples of spiced rum. She decided to go visit her friend in Charlotte, North Carolina, but did not want to drive 15 hours to get there. She faced her fears of flying to avoid driving by herself all that distance. She didn't know what she wanted to do with her life, so I suggested she get a Myers-Briggs profile analysis, and perhaps determine her strengths using Gallup's [Strengths Finder 2.0]. This might help her find a career choice that best fits her interests.
What do all of these have in common? They all faced their fear of flying, either because their situation forced them to, something more important drove them to, or they felt it was just time to do it. Good for them!
As is often the case, many fears are unfounded. Statistically, flying is safer than being on the road in car. As a result of facing their fears, they all got to meet me, and be one step closer to accomplishing their life goals.
In my talks with clients about storage, I find similar hesitation on turning on various storage efficiency features that IBM (and other vendors) have to offer. Let's examine a few of them.
Less than half of businesses have activated "thin provisioning" on storage devices that support this feature. Why? IBM introduced thin provisioning on its RAMAC Virtual Array back in 1997! The technology is well proven in the field. Don't know how to report this for charge-back activity? Charge your end-users for the maximum capacity upper limit. Simple enough!
What about Data Deduplication? IBM has had this feature on its N series since 2007, but it wasn't until IBM came out with the IBM ProtecTIER gateway and appliance models that people started to take notice of this technology. Yes, I agree Hash Collisions can be quite scary on competitive gear, but on IBM ProtecTIER we do not use hash codes, and all data is compared byte-for-byte. For those considering hash-based deduplication, hash collisions in general are quite rare. Jeff Preshing does the math for you in his blog post: [Hash Collision Probabilities]. Of course, if you want to leave no doubt in the minds of a jury of your peers, stick with byte-for-byte comparison methods in the IBM ProtecTIER.
- Lastly, I have heard concerns of using real-time compression? Really? Real-time compression has been used in wide-area network (WAN) transmissions ever since IBM developed the Houston Aerospace Spooling Protocol (HASP) for NASA back in 1973. IBM has offered real-time compression on tape cartridges since 1986, the year I started with IBM, some 27 years ago. And now, real-time compression is available for file-based and block-based disk systems. All of these solutions are based on the Lempel-Ziv lossless compression algorithms introduced in 1977. One customer I spoke with was unwilling to try compression, because it requires thin provisioning as a pre-requisite. How is that for having one fear based on another one!
IBM places a high value on data integrity. For each data footprint reduction method, IBM has designed a solution that returns back the exact ones and zeros, in the correct quantity and order, as was originally stored.
For more on this topic, come see me present "Data Footprint Reduction -- Understanding IBM Storage Efficiency Options" at [IBM Edge 2013 conference] in Las Vegas, June 10-14.
