The hardware behind the newest WordPress.com data center

The people behind the WordPress.com blogging service recently shared some technical information about their new data center in Chicago, which is located in a Layered Technologies facility.

WordPress.com hosts about 5.5 million blogs on its platform, and is not to be confused with the stand-alone WordPress software (which you find at WordPress.org and host yourself).

Here is the server hardware powering the latest WordPress.com data center:

  • 150 HP DL165s dual quad-core AMD 2354 processors 2GB-4GB RAM
  • 50 HP DL365s dual dual-core AMD 2218 processors 4GB-16GB RAM
  • 5 HP DL185s dual quad-core AMD 2354 processors 4GB RAM

That’s a total of 1,440 CPU cores and somewhere between 520 GB and 1.4 TB of RAM. In other words, a significant amount of computing power…

This is one of three data centers that power WordPress.com.

More information, including a (somewhat shaky) video of the server facility is available here.

Why HP? Wouldn’t a more generic set of boxes be more cheaper but just as reliable?

Which set of machines are used for what? Would you be willing to share your architecture?

Why are they not on Amazon’s EC2 or S3 or something like that?

I have a quad proc running gentoo. The speed is insane.

Thanks for the good information. I like wordpress.

“Why HP? Wouldn’t a more generic set of boxes be more cheaper but just as reliable?”

When buying that much equipment, it is usually cheaper to go with a larger brand, in this case, HP. It all depends on how much equipment you buy per year, and what your price structure is with said vendor.

That is awesome, I wonder how much all of that hardware cost?
