    Sylvain: As requested, I took some pictures of my datacenter the other night during my late-night maintenance.

    This is a cabinet with a SAN (Storage Area Network). Basically a giant data storage silo. There are whole rows of these. Each of the drives in this cabinet is 600GB, and there are 128 drives. That means there's about 77 terabytes just in this cabinet alone. The two boxes in the center are redundant control units.

    Just an aisle way showing typical cabinet layout, with a whiteboard on the wall. There are other tools in the datacenter for anyone who needs them, like rolling carts with keyboard and mouse, and even an entire rolling desk if you need a temporary workspace near your cabinet.

    This is another shot down an aisle. Note the wire guides above, the power distribution unit on the left, and the caged area at the end. The holes in the floor are for the air conditioning system. Only every other aisle is air conditioned. The other aisles are called "hot aisles". It's more efficient to alternate hot and cold aisles. Also, if you look closely, you can see that one of the security cameras has been bumped and is pointed at the nearby cabinet instead of down the aisle.

    All of these cabinets are fully enclosed and individually locked. This area is leased on a per-cabinet basis and only the lessor has access to his cabinet. However, for larger environments, the datacenter owner will cage off a whole section of the floor. The cage in this picture is all one company's servers. They have approximately half of this entire datacenter floor. This is different than the other datacenter pics I posted last week where all of the racks are open.

    Thanks for the pictures Scutter!
    It's hard to imagine the storage space of 77 terrbytes (unless you are a big nerd of course).
    It's 76800 times the space I have on the memory card im using in my camera, which is just a 1GB I believe.
    That's a lot of pictures!

    Most new off-the-shelf desktop computers have around 1TB of storage on them, so using a PC is a good basis for comparison.

    So this is a place that's used to host internet servers or is to not linked to the internet and used to keep backup datas for companies and such, just like I can do with a USB flashdrive but at a bigger scale? :dunno:
    Or both maybe. :dunno:

    Both. They've got a huge (seriously, it's huge) connection to the internet and they've got power, backup generators, cooling, 24-hour monitoring, security, etc., so lots of companies will use datacenters like this for services that have to stay up 100% of the time. It's usually cheaper than trying to build your own smaller-scale facility that has all of those things. My company has internet-facing servers here, but we also use it as an off-site storage area for data replicated from the servers in our offices.

    You basically just rent an empty cabinet, and then you buy whatever power and internet bandwidth you require from the datacenter and fill the cabinet with your own equipment. You lock the cabinet doors and then only you have access to it.

    Wow that is so facinating. Who would have thought I would learn this stuff on INGO! Lol!

    Here's a cabinet that's under construction. It already has power, and it looks like the owner has put in a cheap consumer-class firewall (like a Linksys from Best Buy or something), just to terminate his internet connection and make sure it works the way he needs it to before bringing over his equipment and installing it. Note that the remaining side panel hasn't been installed yet, either.

    I could rent one to put my vacation pictures. :D
    I already lost hundred of pictures when my previous PC crashed. :(
    Now I keep them stored on a USB key in the safe.That's kinda the same thing at a much smaller scale I guess.
