The expo opened last night. There are so many fantastic demos and product experts. Las Vegas has a Tivoli buzz on right now.
I'm working in the Hands On Labs room. Pulse labs kicked off Sunday. The hot topics included Cloud, Storage, Automation, Asset Management, and BigFix (a company IBM [acquired and products will now be called Tivoli Endpoint Manager])
I'll try to get you a few updates along the way.

Actually, if the title confuses you, it is because it has a double meaning.
I am looking forward to a year-long celebration on both counts!

Happy New Year, everyone!
Every year, I make [New Year's Resolutions]. Long time readers will recognize this has been a tradition on my blog. In 2007, I spread out my resolutions in a full week of posts: [Data Center Resolutions], [Staying on Budget], [Lighten Up!], [Hone your Tools and Skills]. In 2008, I was so busy blogging about IBM's acquisition of XIV that I did not get around to posting about my New Year's Resolutions until the [second week of January]. In 2009, I chose [more traditional resolutions], based in part on Albrecht Powell's [Top 10 Resolutions].
Last year, I took a different approach. I decided to NOT publicize my resolutions to see if that allowed me to stick to them better. Here is what I had resolved for 2010:
So, while I seem to have been more successful keeping my resolutions by not making them public up front, I think the more important pattern is that when I made many resolutions, I had only a 60 to 80 percent success rate, but when I had fewer, I was more likely to keep them all and be less stressed about it. This could also be psychological, in that feeling that you have completed 60 to 80 percent allows you to forgive yourself for not keeping some of the more difficult resolutions. Therefore, this year, I have decided to focus on a single resolution, to reduce my body fat percentage.
Rather than make you wait 12 months for my results, I plan to provide periodic updates in this blog on my progress. Over the vacation break, I bought and read Tim Ferriss' book [Four Hour Body]. Mo and I are in this together, and we have started Tim's [Slow-Carb diet] last Sunday. My doctor has advised me on which vitamins and supplements to take. Rather than go back to the gym, I will just focus on walking at least 20,000 steps per week, which works out roughly to 10 kilometers.
I'll keep you posted.

Continuing my post-week coverage of the [Data Center 2010 conference], Wednesday evening we had six hospitality suites. These are fun informal get-togethers sponsored by various companies. I present them in the order that I attended them.
Of the six, my favorite was Intel. The food was awesome, the Snuggies were hilarious, and the magician was incredibly good. I would like to think Intel for providing me super-secret inside access to their Cloud Computing training resources and for the Snuggie!

On Wikibon, David Floyer has an article titled [SAS Drives Tier 1 to New Levels of Green] that focuses on the energy efficiency benefits of newer Serial-Attach SCSI (SAS) drives over older Fibre Channel (FC) drives. This makes sense, as R&D budgets have been spent on making newer technologies more "green".
Fellow blogger Hu Yoshida (HDS) encourages people to [Invest in the Future with SAS, SATA and SFF], referring to Figure 1.
Of course, people might consider this an [apples-to-oranges] comparison. Not only are we changing from FC to SAS technology, we are also changing from 3.5-inch drives to small form factor (SFF) 2.5-inch drives. It seems odd to specify 2000 drives, when only two of the five scale up to that level. Few systems in production, from any vendor, have more than 1000 drives, so it would have seemed that would have been a fairer comparison.
However, Hu's conclusion that the combination of SAS and SFF provides better performance and energy efficiency for both IBM DS8800 and HDS VSP than FC-based alternatives from any vendor seems reasonably supported by the data.
Meanwhile, fellow blogger David Merrill (HDS) pokes fun at IBM DS8800 in Figure 2 in his post [Winner o’ the green]. This second comparison was for 4PB of raw capacity, which 4 of the 5 can handle easily using 2TB SATA drives, but the DS8800 is based on SAS technology and does not support 2TB SATA drives. A perf
The main take-away here is that IBM offers both the DS8700 for capacity-optimized workloads, and the DS8800 for perf
