Posts Tagged 'POD'

When I was a kid, my living room often served as a "job site" where I managed a fleet of construction vehicles. Scaled-down versions of cranes, dump trucks, bulldozers and tractor-trailers littered the floor, and I oversaw the construction (and subsequent destruction) of some pretty monumental projects. Fast-forward a few years (or decades), and not much has changed except that the "heavy machinery" has gotten a lot heavier, and I'm a lot less inclined to "destruct." As SoftLayer's vice president of facilities, part of my job is to coordinate the early logistics of our data center expansions, and as it turns out, that responsibility often involves overseeing some of the big rigs that my parents tripped over in my youth.

The video below documents the installation of a new Cummins two-megawatt diesel generator for a pod in our DAL05 data center. You see the crane prepare for the work by installing counter-balance weights, and work starts with the team placing a utility transformer on its pad outside our generator yard. A truck pulls up with the generator base in tow, and you watch the base get positioned and lowered into place. The base looks so large because it also serves as the generator's 4,000 gallon "belly" fuel tank. After the base is installed, the generator is trucked in, and it is delicately picked up, moved, lined up and lowered onto its base. The last step you see is the generator housing being installed over the generator to protect it from the elements. At this point, the actual "installation" is far from over — we need to hook everything up and test it — but those steps don't involve the nostalgia-inducing heavy machinery you probably came to this post to see:

When we talk about the "megawatt" capacity of a generator, we're talking about the bandwidth of power available for use when the generator is operating at full capacity. One megawatt is one million watts, so a two-megawatts generator could power 20,000 100-watt light bulbs at the same time. This power can be sustained for as long as the generator has fuel, and we have service level agreements to keep us at the front of the line to get more fuel when we need it. Here are a few other interesting use-cases that could be powered by a two-megawatt generator:

• 1,000 Average Homes During Mild Weather
• 400 Homes During Extreme Weather
• 20 Fast Food Restaurants
• 3 Large Retail Stores
• 2.5 Grocery Stores
• A SoftLayer Data Center Pod Full of Servers (Most Important Example!)

Every SoftLayer facility has an n+1 power architecture. If we need three generators to provide power for three data center pods in one location, we'll install four. This additional capacity allows us to balance the load on generators when they're in use, and we can take individual generators offline for maintenance without jeopardizing our ability to support the power load for all of the facility's data center pods.

Those of you who are in the fondly remember Tonka trucks and CAT crane toys are the true target audience for this post, but even if you weren't big into construction toys when you were growing up, you'll probably still appreciate the work we put into safeguarding our facilities from a power perspective. You don't often see the "outside the data center" work that goes into putting a new SoftLayer data center pod online, so I thought it'd give you a glimpse. Are there an topics from an operations or facilities perspectives that you also want to see?

SoftLayer data centers are designed in a "pod" concept: Every facility in every location is laid out similarly, and you'll find the same network and server hardware connected to the same network. The idea behind it is that this design makes it easier for us to build out new locations quickly, we can have identical operational processes and procedures in each facility, and customers can expect the exact same hosting experience regardless of data center location. When you've got several data centers in one state, that uniformity is easy to execute. When you open facilities on opposite sides of the country, it seems a little more difficult. Open a facility in another country (and introduce the challenge of getting all of that uniformity across an ocean), and you're looking at a pretty daunting task.

Last month, I hopped on a plane from Houston to London to attend Cloud Expo Europe. Because I was more or less "in the neighborhood" of our newest data center in Amsterdam, I was able to take a short flight to The Netherlands to do some investigatory journalism ... err ... "to visit the AMS01 team."

Is AMS01 worthy of the SoftLayer name? ... How does it differ from our US facilities? ... Why is everything written in Dutch at the Amsterdam airport?

The answers to my hard-hitting questions were pretty clear: SoftLayer's Amsterdam facility is absolutely deserving of the SoftLayer name ... The only noticeable differences between AMS01 and DAL05 are the cities they're located in ... Everything's written in Dutch because the airport happens to be in The Netherlands, and people speak Dutch in The Netherlands (that last question didn't get incorporated into the video, but I thought you might be curious).

Nearly every aspect of the data center mirrors what you see in WDC, SEA, HOU, SJC and DAL. The only differences I really noticed were what the PDUs looked like, what kind of power adapter was used on the crash carts, and what language was used on the AMS facility's floor map. One of the most interesting observations: All of the servers and power strips on the racks used US power plugs ... This characteristic was particularly impressive to me because every gadget I brought with me seemed to need its own power converter to recharge.

When you see us talking about the facilities being "the same," that's not a loosely used general term ... We could pull a server from its rack in DAL05, buckle it into an airplane seat for a 10-hour flight, bring it to AMS01 (via any of the unique modes of Amsterdam transportation you saw at the beginning of the video), and slide it into a rack in Amsterdam where we could simply plug it in. It'd be back online and accessible over the public and private networks as though nothing changed ... Though with Flex Images making it so easy to replicate cloud and dedicated instances in any facility, you'll just have to take our word for it when it comes to the whole "send a server over to another data center on a plane" thing.

While I was visiting AMS01, Jonathan Wisler took a few minutes out of his day to give a full tour of the data center's server room, and we've got video and pictures to share with more shots of our beautiful servers in their European home. If there's anything in particular you want to see from AMS01, let us know, and we'll do our best to share it!

P.S. Shout out to the SLayers in the Amsterdam office who offered their linguistic expertise to add a little flair to the start of the video ... From the four employees who happened to be in the office when I was asking for help, we had six fluent-language contributions: English, Italian, French, Dutch, Polish and German!

**UPDATE** After posting this video, I learned that the "US" server power plugs I referred to are actually a worldwide computer standard called C13 (male) and C14 (female).
