    Re: New server build, Disk and UPS advice.

    If you want to be sure your data is safe and also be able to relax during a rebuild id suggest a raid 5 build on your nas and save the other two disks for a striped backup server.

    Since you are considering encryption I guess that you fear possible theft which means no raid in the world will save your data so backup is really your only choice.

    Sure everything CAN fail at the same time but at least that possibility is very slim.

    Regarding raid approved disks, I don't have any bad experience what so ever with consumer disks. I have had a few builds that have been running for years without any issues.


    The apcups daemon logs all events on the APC. I think that you can set up scripts for different events but I'm not sure. Check the documentation on their website.

    If you just want to mess around with virtualization i'd recommend VirtualBox headless with phpvirtualbox as web management gui.
    Not the best virtualization for a server but I ran it for years on a 10.04 server while experimenting with different OS's and without any issues.

    +1. I use that setup now, but I have heard KVM is easier on resources, but I don't feel like messing with a working setup.

    Not quite true in all scenarios. If you lost both drives from the same mirror, you could lose the whole array. Personally, I use RAID6 + backups at home for anything I couldn't cope with losing.

    Another vote for APC here. Works great and I have it setup to email me when the power goes out - though I needed to remember to plug the broadband router into the ups as well so that I actually got the email if I was out of the office.

    Owie.

    I would +1 RAID6.

    Hi all,

    Thank you for all the advice, I did not realize there were any replies and did not get any notifications.

    After a lot of back and fourth the server is installed, I went for a RaidZ with 5 drives, and the OS, L2ARCH and ZIL on the SSD.
    I will add an extra or two disks down the road as a hot spares, connected on USB3, I will probably be swapping out the drives in the array to get some distribution on productions dates.

    For Backup, well this is one of my backup destinations. For really important data I have already a distributed backup system in place with data saved on several locations.


    After reading and comparing prices I went for a CyberPower CP1500AVRLCD.
    It has Linux divers, and documentation and It also had a good price for a 1500VA that only the SMX editions of APC had, and from the acupsd site, it says not to get the SMX editions due to incompatibility.

    Wow ZFS on Linux? How well is that working?

    So far so good (I think).
    I was a bit concerned about the speed, but it was all in my head.
    It seems ZFS like RAM, and lots of it. and it can be seen why.
    When staying with file sizes that are within memory, it is lightning fast.

    I was also seeing a strange behavior where writing was faster than reading in some configurations, but again is suspect this was due to me not doing it correctly.

    I will probably have to tweak it a bit, I think I reinstalled a few times before settling with a config I liked.
    And for a few days it has been running good, I guess I will see how it works over time.
