With Hadoop, you can take a standard PC server and connect it to one hundred, several hundred or even thousands of other servers. Hadoop distributes the data files across these nodes, using them as one large file system to store and process the data. That's why it's called a distributed file system. The record number of nodes to date is 4,000 servers, all functioning as a unit using Hadoop. This means if your data maxes out the capacity of your hardware, you simply add more nodes.
