Introducing data center fabric, the next-generation Facebook data center network
The more than 1.35 billion people who use Facebook on an ongoing basis rely on a seamless, “always on” site performance. On the back end, we have many advanced sub-systems and infrastructures in place that make such a real-time experience possible, and our scalable, high-performance network is one of them.
Facebook’s production network by itself is a large distributed system with specialized tiers and technologies for different tasks: edge, backbone, and data centers. In this post, we will focus on the latest developments in our data center networking and unveil the next-generation architecture that we have successfully deployed in our new Altoona facility: data center fabric.
“How we scaled Instagram”, by Mike Krieger (video)
Mike Krieger, co-founder of Instagram, talks about their tech setup, how they scaled from one server in LA, to AWS and ultimately Facebook’s own infrastructure.
rackspot.pt changed his name to easyhost.pt … this is what happened…
they are now using online.net infrastructure… my blog, hosted on rackspot.pt – now on easyhost (online.net) is getting lot of database errors…. looks like they are even using the db connections limits…. fuck!

I’m afraid you dont even get something as simple as:
Raid 1 : faast
Raid 0 : slow
Raid 1 brings safety by allowing you to half of screwed drives
Raid 0 brings you the comfort to know that when a drive is crashed, you can go home. To cry.
But speed wise it’s a different story:
– You have twice the same data, so write speed should be, let’s say, “normal
– You have 2 disks to read from. With the proper disks, controllers and bla bla, you read faster.
– You write faster
– You read faster
So, in some cases where you require those little boosts, and the data is not “i’m going to kill myself if i lose this” important, then why not, just stack a few extra drives nearby
In jflory’s case, a failed drive, would mean both drives are not useable, then waiting for the replacement, and timing … Yes that’s a lot of downtime for gaining a few G you might be able to save up anyway.
Dont be that guy Jflory!
