Lately I have been resting too, and today I had a flash developer: I am leaving too by the branches with the content of the site, so I'm going to return to the technical articles that I like to my both and alternate with other modalities.
With this new series, I want to explain how you can implement your own NAS, modular and with various types of RAID home in a the of life desktop PC running stably the 24 hours a day under a system GNU/Linux on a desktop PC.
You and your needs put the minimum specifications. For a proof of concept with a Pentium 4 and a pair of hard drives of (for example) 80GB rescued from the Junk room or two 4GB pendrive vais sobrados.
There are multiple distributions that allow us to carry it out in a way more automated, quick and easy, as Turnkey (based in Ubuntu) o FreeNAS (based in FreeBSD). And each one of them with a large community behind, but it is not the same thing and now I will explain because.
These systems are well known to the community, and if we care about our safety minimum understand that too many people know the functioning and the nooks and crannies of these distributions that come as well to learn in class is a NAS and how it works.
I.e.: If you're not a paranoid security, anti-whole default as I perhaps it is your best option.
For my part I prefer to rather robust and durable in time, investing my time on doing something to my measure and which can be updated or modified according to my needs. A couple of years ago I thought about saving for one Tower-Rack and a 5U Cabinet but lacking of budget and space I began to laps and laps in the lead, so I keep the ACE up the sleeve and on future deliveries will explain how I solved the issue.
As for the operating system, as my desktop PC and still I have not migrated to Debian, I will use Ubuntu Desktop. Although if the PC that you have only to be used as a server I recommend a distribution Server without graphical interface, especially if your PC to do this is a P4.
In addition it is the server touch it as little as possible and in any case we must remember that it is not the PC for visits, but our server that we must remain isolated.
In summary: The next few days I'll be expanding this series pasito a pasito, and the idea is to explain what a RAID and both types of RAID There are differences between them as, It's a NAS, need packages, that Hardware can optionally, as we have to configure everything, and as we can assemble our Server in an economic way.
Until soon pedestrians!
