经常在各种描述中看到 Commodity Hardware 这个词？出于好奇心，查阅整理了一些资料，如下：
> Commodity hardware refers to cheap, standardized servers that are easy to buy off the shelf from any vendor. Here’s a typical example of a 2u, 2CPU commodity hardware server: > > - Supermicro SYS-1028R-TDW 1U rack server > - Two Xeon E5-2600 v3 CPU sockets > - 16 RAM slots, holding up to 1TB RAM > - 8 2.5″ hot-swap SATA 3 drive bays > - 2 PCI-E 3.0 x16 full height half length slots > - $900 at NewEgg
> The term “commodity hardware” used to mean really crappy gear, but when you look at these numbers, that’s not necessarily the case anymore. You can build yourself quite the army of pizza boxes. > > When vendors say, “You can deploy our solution on commodity hardware,” they’re not saying you’re going to get amazing performance with 16GB of RAM and a couple of spinning rusty frisbees. It’s time to reset your expectations about what commodity means.
> Swift is designed to run on commodity hardware. At Rackspace, our storage servers are currently running fairly generic 4U servers with 24 2T SATA drives and 8 cores of processing power.
- high energy physics
> Commodity hardware running the open source operating system Linux is playing various important roles in the field of high energy physics.
> A scalable shared database enables you to scale-out a database using commodity hardware for reporting servers and volumes and to achieve a smooth upgrade path.
- Computer hardware
> Computer hardware that is affordable and easy to obtain. Typically it is a low-performance system that is IBM PC-compatible and is capable of running Microsoft Windows, Linux, or MS-DOS without requiring any special devices or equipment.
