Not going to run out of disk space anytime soon

Yes, I admit it openly: I’m a hoarder – data hoarder that is.

Weeks ago the 3 terabytes in one of my servers were 90% consumed. Yes, there is lots of junk on it, but also a lot of data that I want to keep. The server is accessible from all devices in the home network and I make good use of it. I always eyed a Network Attached Storage (NAS) device as a remedy to my storage requirements. With the new job (more on that in another post) I also get to juggle with more data than ever before. Just to give you an idea: the main database I’m dealing with on a daily basis is around 9GB and I have multiple versions of it around.

My employer agreed to purchase a Drobo 5N NAS for me. All I needed to do was to fill it with disks. I purchased 4 3TB Seagate disks (Barracuda ST3000DM001 to be precise) and stuffed them into the unit. Because of the way that the Drobo handles disks and disk space, I ended up with a bit over 8TB as usable space. After some spring cleaning I also shrunk the data from the server down to a more manageable 1.5TB.

So far the NAS has been working flawlessly and I get close to the maximum transfer speed I can get on a Gigabit network.

    Just curious, those 4 disks that you stuffed the Drobo with, are you doing any striping or other data integrity or recovery techniques with them? I looked into Drobo and a few other NAS solutions a while back and got lost in all the complexities of disk and data management. So I stopped, though I shouldn’t have, since I lost the research and education I gained in my head from that exercise.

    Doesn’t sound like you’re using this as a backup solution, rather as a straight NAS resource on your local network.

    Hi Rob – the Drobo uses it’s own version of striping/parity bits to implement the server. I’m not sure what exactly is being used, but I can tell from the amount of available disk space that one disk is used exclusively to implement a fail-safe. In case a disk goes bad the Drobo is supposed to tell me about it with different lights. In theory just replacing the faulty disk should make everything work again. I’ll let you know when that happens …

    Yes, the unit is mainly used like a NAS. I do send backups there as well, but not the entire system just select portions (robocopy to the rescue).
