Logic Challenge: SoftLayer Server Rack Riddle

After I spent a little time weaving together a story in response to SKinman's "Choose Your Own Adventure" puzzle (which you can read in the comments section), I was reminded of another famous logic puzzle that I came across a few years ago. Because it was begging to be SoftLayer-ized, I freshened it up to challenge our community.

In 1962, Life International magazine published a logic puzzle that was said to be so difficult that it could only be solved by two percent of the world's population. It's been attributed to Einstein, and apparently Lewis Carroll is given a claim to it as well, but regardless of the original author, it's a great brain workout.

If you haven't tried a puzzle like this before, don't get discouraged and go Googling for the answer. You're given every detail you need to answer the question at the end ... Take your time and think about how the components are interrelated. If you've solved this puzzle before, this iteration might only be light mental calisthenics, but with its new SoftLayer twist, it should still be fun:

Einstein's SoftLayer Riddle

The Scenario: You're in a SoftLayer data center. You walk up to a server rack and you see five servers in the top five slots on the rack. Each of the five servers has a distinct hard drive configuration, processor type, operating system, control panel (or absence thereof) and add-on storage. No two servers in this rack are the same in any of those aspects.

  • The CentOS6 operating system is being run on the Xeon 3230 server.
  • The Dual Xeon 5410 server is racked next to (immediately above or below) the server running the Red Hat 6 operating system.
  • The Dual Xeon 5610 server uses 50GB of CloudLayer Storage as its add-on storage.
  • The Quad Xeon 7550 server has no control panel.
  • The Cent OS 5 operating system is racked immediately below the server running the Red Hat 5 operating system.
  • The server using 80GB NAS add-on storage is racked next to (immediately above or below) the server with two 100GB SSD hard drives.
  • The server running the Red Hat 5 operating system uses Parallels Virtuozzo (3VPS) as a control panel.
  • The server running the Windows 2008 operating system has two 100GB SSD hard drives.
  • The server using Plesk 9 as a control panel is in the middle space in the five-server set in the rack.
  • The top server in the rack is the Dual Xeon 5410 server.
  • The Xeon 3450 server has two 147GB 10K RPM SA-SCSI hard drives.
  • The server using 20GB EVault as its add-on storage has one 250GB SATA II hard drive.
  • The server with four 600GB 15K RPM SA-SCSI hard drives is next to (immediately above or below) the server using 100GB iSCSI SAN add-on storage.
  • The server using cPanel as a control panel has two 2TB SATA II hard drives.
  • The server with four 600GB 15K RPM SA-SCSI hard drives is racked next to (immediately above or below) the server using Plesk 10 (Unlimited) as a control panel.
  • One server will use a brand new, soon-to-be-announced product offering as its add-on storage.

Question: What is the monthly cost of the server that will be using our super-secret new product offering for its add-on storage?

Use the SoftLayer Shopping Cart to come up with your answer. You can assume that the server has a base configuration (unless specifically noted in the clues above), that SoftLayer's promotions are not used, and that the least expensive version of the control panel is being used for any control panel with several price points. You won't be able to include the cost of the add-on storage (yet), so just provide the base configuration cost of that server in one of our US-based data centers with all of the specs you are given.

Bonus Question: If you ordered all five of those servers, how long would it take for them to be provisioned for you?

Submit your answers via comment, and we'll publish the comments in about a week so other people have a chance to answer it without the risk of scrolling down and seeing spoilers.

Choose Your Own Adventure

I was unbelievably busy last week, and surprisingly, the busyness I'm referencing did not even involve my official responsibilities in compliance. I was planning on writing a blog to share some of the fun/insane/ridiculous things that happened, and I thought of a way to mix it up a little and make a challenge out of it for our readers.

Have you ever seen those image-based logic puzzles where you're given a series of images and challenged to put them in order to create a story? Here's an example:

Logic Puzzle Example

What story are those pictures trying to tell? A boy [6] grabs a fishing pole [4], and finds a fishing hole [5]. He baits his hook [3] and waits for the catfish to quit posing [2] and bite the hook! He takes his catch home, and his mom fries it up [1]. MMMM Good [7]!

You could probably interpret it a different way and "choose your own adventure" where the anthropomorphized fish deep fried the boy ... Depends on how far outside the box you think. The answer the question was meant to have is the one above. Now that you see how it works, I have a logic puzzle for you to try and figure out about what happened during my week last week.

All ten of the pictures below were taken in the span of 56 hours ... If you can come up with the correct story, I'll send you a prize (detailed below). If you can come up with a creative story that isn't correct, I can probably find something to send you as well. Without further ado, here are the pieces of the story [Click for Larger Version]:

Logic Puzzle Example

If you've been to the SoftLayer Blog this week, you know that we have a "Kids Meal" kind of special going right now where for the next few months if you buy a server and email us, you can get an official SoftLayer Bobblehead! To piggyback on that giveaway, the first person who posts a comment with the correct order of the photos to answer the puzzle (or the funniest answer if no correct answers are posted), will get my personal FULL SET of official SLobbleheads. Yes, the full set! You won't have to wait to place your server orders in the next month to complete your bobblehead collection (though I hope you still keep ordering servers).

So what are you waiting for? Tell me the story!
