Adding more internal HDD or a NAS for aditional storage



  • Looking for recommendations: I have a small network that I have been imaging using fog .32 on Ubuntu 10.04 on a system w/ a single 700 GB SATA drive and I am looking to expand the drive space to save more images. Should I be looking to add multiple TB SATA drives or looking for a NAS. What would be the best solution long term? (~3 yrs)

    Thanks

    You really only need a performance boost if you do multiple deploy or multiple upload tasks at the same time. If you are just looking to add storage, you can easily put in a bigger drive. If you want to span multiple drives, you’ll have to look at implementing some form of RAID.

    Using a NAS, connected via the network card, would probably slow down your imaging process even to one machine unless you have a dedicated NIC for the NAS, and a dedicated one for the client network.

    whilst I have not done this myself at work, and only have it on a dsktop. my home setup is raid 10, so will vouch for Kevins post and say a hardware raid 10 setup with two linked gig ports is the ultimate setup

    Personally, I would build a dedicated box with 2 gig NICs and run a system in RAID 10. You would trunk (link aggregation) the two ports, if possible, which would really help bandwidth wise. But that really depends on your network size, if it’s not all that big, you should easily be able to get away with a single gig port. The RAID 10 or really 0+1 is the best of both worlds in terms of hard drive speed and reliability. The down fall is that you get only 50% of your drive space. I used to run my home machine with 4 500GB drives in a RAID 10 array. You get the full disk redundancy like RAID 1, but half the data is on 1 drive, half on the other. This really helps with the speed since each drive is having to look at only half the data, RAID 0. The downfall being that both drives are mirrored to the second pair of drives, this is where you lose the 50% storage. So my 4 500GB drives yielded me only 1 TB of storage, but with increased drive speeds and full redundancy for up to 2 drive failures.

    Everything should be relatively cheap to get setup and gives you some piece of mind. This may very well be overkill for what you need, but this is just my .02 cents
