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 performance-oriented configuration with four distinct DS8800 boxes employing 600GB SAS drives is used instead, causing the data for the DS8800 to stick out like a sore thumb, or perhaps more intentionally as a middle finger.
The main take-away here is that IBM offers both the DS8700 for capacity-optimized workloads, and the DS8800 for performance-optimized workloads. Some competitors may have been spreading FUD that the DS8700 was withdrawn last month, it wasn't. As you can see from the data presented, there are times where a DS8700 might be more preferable than a DS8800, depending on the type of workloads you plan to deploy. IBM offers both, and will continue to support existing DS8700 and DS8800 units in the field for many years to come.

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].
I use two Cloud-Computing based photo-sharing services, [KodakGallery.com] and [Flickr.com], which serve two completely different purposes.
- Kodak Gallery
Formerly, this was Ofoto, but was acquired by Kodak. I started using this service back in 2002, and had over 12,000 photos uploaded over the past 8 years. I was able to share all my photos with my friends and family, and they could simply order whichever prints they want and have them shipped directly to them. They have incredibly high-professional photo-based products, like calendars and coffee table books, that you can produce from your own photos.
Sadly, the fine folks at Kodak Gallery decided they did not want my business anymore, and purged my 36GB of files from their system. To be fair, they did hint that they were having financial problems with an "Archive CD" offering, which would have allowed me to get a set of CDs or DVDs holding the high-resolution graphics of all my uploaded photos. This would have cost $150 or so, and if you uploaded more photos, there was no option to get the "delta" of photos uploaded since your last archive, so it would have cost me $150 every year or so to get an updated "backup" of my files. It seemed expensive and unnecessary at the time, given that I was sure that Kodak was not going out of business anytime soon, and that I was sure they took their own backups of all the photos that people put in their charge.
The problem is that Kodak Gallery was a free service, subsidized by people ordering physical prints and other products. As such, I got lots of email from Kodak every month, offering me free shipping, special promotions, and seasonal discounts. It was so much that I had all email from them automatically routed to a different sub-folder, that I would never look at, unless I was about to make a purchase and needed to find the best coupon code or free shipping option currently offered. This also had the unintended consequence that I missed the following series of notes:
- Important: From the Gallery's General Manager (April 17)
- Second notice: Our storage policy has changed (April 24)
- Final notice: Your stored photos may be deleted (May 8)
- We don't want to delete your photos (May 22)
All the notes mentioned the new "Storage Policy", here is a quick excerpt:
"The fact is, we store billions of photos for our 75 million members. The quality storage service the Gallery provides is significant in terms of our business costs.
So that we can provide the highest level of service, we're now asking all Gallery customers to make an annual nominal purchase in exchange for photo storage. We've modified our Terms of Service policy accordingly: if your Gallery photo storage equals 2 gigabytes or less, we're asking you to spend $4.99 annually; if more than 2 gigabytes, $19.99 annually.*
One last thought: We value and appreciate your business, and we want to continue our relationship with you in a spirit of mutual support and benefit. That's always been the Kodak way."
Since they had no response from me, nor saw any purchase activity, my 36GB of files were deleted on June 17. I discovered all of this when I contacted Kodak to find out where my files were last weekend during my "Spring Cleaning". I asked if I could at least get the final set of "Archive CDs", but they told me they were purged completely.
I understand the economy is in a recession, and many free cloud-based services are losing money and going under. I can understand they were faced with tough choices, Kodak opted to switch from a free service to fee-based service.
Albert Einstein defined Insanity as "doing the same thing over and over again and expecting different results." In general, if I am trying to get a hold of someone, and email isn't working, then I try something different, try them by phone, try them by snail mail, and so on. With the deluge of emails, people sometimes declare "email bankruptcy" by deleting everything in their inbox after coming back from vacation, or implement filters to automatically route mail to separate folders. I think it is unrealistic to expect that everybody reads every piece of email that you send them.
I would have liked for Kodak to have done at least one or more of the following, given that I had been such a long time customer, and they had earned hundreds of dollars in revenues from all the purchases, over the years, not just directly from me, but from my friends and family, of photos I uploaded to their website:
- Send me a letter after not receiving any response from the first three notices. They sent me promotional materials and offers for 20 percent discounts, so they had my active snail mail address on file correctly. With 75 million users, it would have cost $33 million USD to send out snail mail letters to everyone, but for the subset of power-users who have more than 2GB of files, a snail mail letter might have gotten more $19.99 purchases they needed to stay in business.
- Called me on the phone. Yes, they also had my phone number in their database.
- Go ahead and charged my credit card on file $19.99 without a purchase, and given me a credit towards a future purchase. Something like: "You have not purchased anything in the last 12 months, so we charged your credit card, per our Terms of Service, but you can use this as a credit towards something in the next 60 days."
On the plus side, my "Spring Cleaning" project was done. You can't organize what you don't have anymore.
- Flickr from Yahoo
I started using Flickr back in 2008 to hold photos and graphics for this blog. Flickr holds various sizes of photos that I can use directly with HTML tags. Clicking on the photo in the blog will take you to Flickr's service and allow you to see the large size resolution. The "Lotus Connections" that I have on IBM DeveloperWorks only offers 24MB of photo space, so Flickr was a nice alternative.
Unfortunately, Flickr had adopted a new policy that only the most recent 200 pictures would be visible, and I had already reached 170 photos. Rather than start deleting photos from my older blog posts, I opted to upgrade to the "Flickr Pro" account, with a fee of only $24.99 per year.
Hopefully, by paying an annual fee and choosing a successful and profitable Cloud-Computing company, I won't experience another traumatic loss. However, it does remind me that it is my responsibility to keep my own copies of these photos, just in case.
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.

Well, I'm back from my adventure. For those who did not follow my tweets, here is a quick recap. Not counting the day we flew from Tucson to Minneapolis, or the day we flew from Memphis back to Tucson, Mo and I spent nine days on the road, covering 1549 miles, or roughly two thirds of the Mississippi River.
- Starting in Minneapolis, MN - roller coaster rides at the [Mall of America], the [SPAM museum in Austin, MN], the windmill farm in Southeastern Minnesota, and drove along the river from Red Wing down to Reads Landing. Stayed in a nice B&B called [The River Nest].
- The [National Eagle Center], Buena Vista park at Alma, WI, wine tasting at the [Danzinger Vineyards], see the paintings at the [Minnesota Marine Art Museum], tasty "walnut balls" at [Historic Trempealeau Hotel], the [world's largest six pack] and the [Shrine of our Lady of Guadalupe] in La Crosse, WI. Stayed at a motel in Prarie Du Chien, WI.
- Villa Louis in Prarie Du Chien, pictures in front of the Lady Luck pink elephant in Marquette, IA. Cheese Curds at Pike's peak just south of McGregor where the Wisonsin river merges into the Mississippi river, wine tasting at the [Double L vineyards], lunch at [Breitbach's in Balltown], rode the [Fenelon Place Elevator] in Dubuque, walked through the [Grotto at Dickeyville, IL], deep fried chicken livers at [Kalmes General Store] in St. Donatus, IA. Stayed at a hotel in Clinton, IA.
- Celebrated Fourth of July at the [Wide River Winery] just north of Clinton, IA. Saw "The Last Airbender" at the local cinema.
- Buffalo Bill Cody museum was closed on Monday, ate my first loose-meat sandwich lunch at Maid-Rite in Moline, IL, the button museum, aka [Muscatine History and Industry Center] was also closed on Monday, took pictures in the corn fields at Oquawka, IA, ate smoked Carp from [Quality Fisheries, in Niota, IA], ate raisin pie at the Maid-Rite in Quincey, IL. Stayed in a hotel in Hannibal, MO - home of Mark Twain.
- Took the Mark Twain paddleboat tour up and down Mississippi river to see Jackson island, almost drove car into the river at Winfield, MO where the Ferry was supposed to be, ate one of everything on the menu at [Fast Eddy's Bon-Air], rode up to the top of the [Gateway Arch] in St. Louis. We stayed in a hotel in downtown St. Louis, MO.
- Ate donuts at World's Fair Donuts and frozen custard called "concrete" at [Ted Drewes'] in St. Louis. Popeye museum in Chester, IL, ate dinner at Dixie BBQ in Jonesboro, and took pictures of the huge Superman statue in Metropolis, IL. Stayed in a hotel in Paducah, KY.
- Read the murals on the flood walls and toured the [National Quilt Museum] in Paducah, KY. Lunch at Nicky's BBQ just north of Clinton, KY, stopped for photos at Reelfoot Lake in Tennessee. Stayed in a hotel in Memphis, TN.
- Tour of [Graceland Mansion], home of Elvis Presley, and [Mud Island], ate dinner at Gus' World Famous Hot & Spicy Chicken, all in Memphis, TN.
Well, now I have a lot of unread emails and blogs to get through! My next trip is the [IBM System Storage Technical University] in Washington DC, July 26-30.
Continuing my rant from Monday's post [Time for a New Laptop], I got my new laptop Wednesday afternoon. I was hoping the transition would be quick, but that was not the case. Here were my initial steps prior to connecting my two laptops together for the big file transfer:
- Document what my old workstation has
Back in 2007, I wrote a blog post on how to [Separate Programs from Data]. I have since added a Linux partition for dual-boot on my ThinkPad T60.
|/dev/sda1||26GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||12GB||ext3||/(root)||Red Hat Enterprise Linux 5.4|
|/dev/sda6||80GB||NTFS||D:||My Documents and other data|
I also created a spreadsheet of all my tools, utilities and applications. I combined and deduplicated the list from the following sources:
- Control Panel -> Add/Remove programs
- C:\Program Files
- Start -> Programs panels
- Program taskbar at bottom of screen
The last one was critical. Over the years, I have gotten in the habit of saving those ZIP or EXE files that self-install programs into a separate directory, D:/Install-Files, so that if I had to unintsall an application, due to conflicts or compatability issues, I could re-install it without having to download them again.
So, I have a total of 134 applications, which I have put into the following rough categories:
- AV - editing and manipulating audio, video or graphics
- Files - backup, copy or manipulate disks, files and file systems
- Browser - Internet Explorer, Firefox, Opera and Google Chrome
- Communications - Lotus Notes and Lotus Sametime
- Connect - programs to connect to different Web and Wi-Fi services
- Demo - programs I demonstrate to clients at briefings
- Drivers - attach or sync to external devices, cell phones, PDAs
- Games - not much here, the basic solitaire, mindsweeper and pinball
- Help Desk - programs to diagnose, test and gather system information
- Projects - special projects like Second Life or Lego Mindstorms
- Lookup - programs to lookup information, like American Airlines TravelDesk
- Meeting - I have FIVE different webinar conferencing tools
- Office - presentations, spreadsheets and documents
- Platform - Java, Adobe Air and other application runtime environments
- Player - do I really need SIXTEEN different audio/video players?
- Printer - print drivers and printer management software
- Scanners - programs that scan for viruses, malware and adware
- Tools - calculators, configurators, sizing tools, and estimators
- Uploaders - programs to upload photos or files to various Web services
- Backup my new workstation
My new ThinkPad T410 has a dual-core i5 64-bit Intel processor, so I burned a 64-bit version of [Clonezilla LiveCD] and booted the new system with that. The new system has the following configuration:
|/dev/sda1||320GB||NTFS||C:||Windows XP SP3 operating system, programs and data|
There were only 14.4GB of data, it took 10 minutes to backup to an external USB disk. I ran it twice: first, using the option to dump the entire disk, and the second to dump the selected partition. The results were roughly the same.
- Run Workstation Setup Wizard
The Workstation Setup Wizard asks for all the pertinent location information, time zone, userid/password, needed to complete the installation.
- Re-Partition Disk Drive
I burned a 64-bit version of [System Rescue CD] and ran [Gparted] to re-partition this disk into the following:
|/dev/sda1||40GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||15GB||ext3||/(root)||Ubuntu Desktop 10.04 LTS|
|/dev/sda6||245GB||NTFS||D:||My Documents and other data|
- Redefine Windows directory structure
I made two small changes to connect C: to D: drive.
- Changed "My Documents" to point to D:\Documents which will move the files over from C: to D: to accomodate its new target location. See [Microsoft procedure] for details.
- Edited C:\notes\notes.ini to point to D:\notes\data to store all the local replicas of my email and databases.
- Install Ubuntu Desktop 10.04 LTS
My plan is to run Windows and Linux guests through virtualization. I decided to try out Ubuntu Desktop 10.04 LTS, affectionately known as Lucid Lynx, which can support a variety of different virtualization tools, including KVM, VirtualBox-OSE and Xen. I have two identical 15GB partitions (sda2 and sda3) that I can use to hold two different systems, or one can be a subdirectory of the other. For now, I'll leave sda3 empty.
- Take another backup of my new workstation
I took a fresh new backup of paritions (sda1, sda2, sda6) with Clonezilla.
The next step involved a cross-over Ethernet cable, which I don't have. So that will have to wait until Thursday morning.

This week I got a comment on my blog post [IBM Announces another SSD Disk offering!]. The exchange involved Solid State Disk storage inside the BladeCenter and System x server line. Sandeep offered his amazing performance results, but we have no way to get in contact with him. So, for those interested, I have posted on SlideShare.net a quick five-chart presentation on recent tests with various SSD offerings on the eX5 product line here:
Sandeep, if you see this, we would also be interested in seeing your results as well.
