About FatCow.com's server farm:

FatCow has a couple data centers just outside of Boston. Their 2400 square feet of space contains 800 Servers and half a Petabyte of storage.

Fatcow runs a pooled network which means any server on their network has the ability to serve any webpage requested. This means that any available machine will be the one to serve a customer's Web pages, giving faster loading times and fewer service interruptions than traditional hosting infrastructures.

Fatcow's pipe to the rest of the internet contains dual redundant M7I routers and multiple firewalls incorporating IDP technology with BGP border gateway protocol. Site data is parsed by dual Big Iron load balancers and managed by DELL servers. This type of architecture allows Fatcow to customize every machine to the service it performs, which means more density per box, and ultimately, faster and more reliable services. No pool lives entirely on one rack so even a compete loss of a rack's switch or power will not take that service down.

Fatcow's relies on network-attached storage so any machine has access a customer's data. Each machine is paired with another identical machine that is programmed to take over seamlessly if the primary machine crashes. These computers are also backed up to another set of storage units that have a mirror copy of the data in case of disk failure. They process 5.5 gigabits of storage per second!
