    It's a dmraid,

    so you are using the onboard raid? that normally does not work in linux..

  • earl said: dmidecode |more

    I'm not sure what to look for. I don't find something related to disk information?

    earl said: so you are using the onboard raid? that normally does not work in linux..

    That's what they deliver to me. It got me errors like below. I am considering to reinstall by myself and use mdadm, but for its current purpose I think it's okay.

    The try above was on an empty VPS, but I just realized something was different from when I first got it: I was using CentOS this time and Ubuntu before.

    On a new Ubuntu 12.04 install it gets about 632 MB/s, on Debian 7 980 MB\s, and going back to CentOS 6 358 MB/s. None quite as fast as when I first signed up but apparently there are some very different default sysctl settings!

    Not only that, but each of those use a different amount of ram centos is the most hungry as we all know less ram less performance in dd, so please, try with the new RAM I gave you.

    nice they gave you all the same drive.. the server is pretty nice too.. with AMD cpu you can do nested vm's, and the 1045 supports RVI so techinically u can install kvm inside a nested proxmox.

    Thanks, nice new commands for this newbie's notes. For now it's running OpenVZ, mostly for experimental. I planned to try proxmox, but recent news about Feathur being cheap/free with no upfront cost somehow interest me more. :D

    Install feathur in proxmox.. then you get to try out both.
    the great thing about proxmox is the ready made OVZ turnkey templates.. probably over 100 template like, wordpress, LAMP even vanilla forum, etc..

    you should install it, you won't regret it..

    Hum strange. Centos is the most memory hungry but should have had enough of it, yet is still the slowest.
    Since it is xen, it will be slower than ovz but not that slower, I think this is something about the CentOS kernel.
