Online.net Dedibox XC 2016 BIOS Bug?

exception0x876exception0x876 Member, Provider

I've ordered the Dedibox XC 2016 HDD version to use for my personal needs, but I noticed some serious slow down during filesystem creation via mkfs.ext4. So I rebooted under Rescue system just to find out the hilarious write speed of their hard drive

dd if=/dev/zero of=/mnt/sda1/test bs=1M count=100 conv=fdatasync
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 8.3943 s, 12.5 MB/s

I should mention that the read speed was ok and always stayed at 100MB/s+. I created a support ticket and their rep said:

Hello,

thanks for your patience.
After further check, it seems like we have a BIOS bug affecting our XC.

The port is not running properly (SATA II instead of SATA III) and offer lower performance that it should.
Our engineering team is already working on it, and we'll deliver a patch in the coming weeks for that kind of issue.

Regards, Julien V.
L2 Technician @ Online.net.

I don't think that is the case though, since if that was true all other customers would experience the same issue. Is it?

  • I have the same "issue" on 1 of my 2 XCs. Makes it even more weird.

    My XC 2016 is fine, but yeah their BIOS is buggy.

  • Mine SSD version works well about 260 MB/s, would be more on SATA3.

  • Mine is about 80MB/s, but the XC Iam cancelling can do 100MB/s

  • @Spacedust said: Mine SSD version works well about 260 MB/s, would be more on SATA3.

    How to get 260MBps?

    Mine just 175MBps on Ubuntu 14.4

    It's definitely not just you; I'm having the EXACT same issue on my SC and XC servers; funny how they are both part of the 'Online.net Labs' platform. Looks like their custom designed platform has a major issue with the BIOS.

    I've had this issue on two server now (They swapped me to another earlier today; same issue):

    $ sudo dd if=/dev/zero of=/mnt/sda2/tmp/test1.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1,1 GB) copied, 26,9245 s, 39,9 MB/s

    It's quite low and it seems to fluctuate a LOT, and that is in rescue mode!

    Shame this wasn't something that was tested before deploying their 2016 range...

    Do you get the port manifesting itself as SATA III on any other OS / OS version? There is an issue with I believe C236 chipset, SATA and CentOS 7.1, it works perfectly fine on 6.7 and 7.0 though.

    The rescue system is Ubuntu 14.04 based and I used Centos 6.7 for my installation. Both have this slow speed. I think the problem is not SATA2 itself, since it should allow to push like 200MB/s without problems.

    Stupid question; if the boards used in these servers are custom specific to Online.net, will they likely be the developers of the BIOS running on them? In other words, will the time frame which has been quoted likely be accurate?

    I received a similar time-frame for a fix of a couple of weeks when contacting support. I'm very surprised this got through system testing to be honest, especially if it's custom hardware.

    What is even more surprising though is I've seen a few benchmarks around from users who have the SSD version of the XC 2016 and their benchmarks are over 150MB/s. You'd think a BIOS issue like this would affect all drive types since they all use the same interface (SATA) wouldn't you?

    I just get around 60 MB/s on my SC 2016

  • I was thinking about getting the XC SSD this month, but this BIOS issue sounds pretty jank.

    Will shill for Pop-Tarts(must be strawberry flavour).

  • akhfaakhfa Member

    How much HDD speed do you expect in normal case? Is it about 100 MB/s ?

    This is on a 10000 year old failing WD green 1TB drive

    I'd say you should expect at least 100MB/s yeah.

  • Mine XC 2016 SSD gets 213 MB/s under load on Proxmox host machine ;)

  • They've added FreeBSD in installer. How were you able to get CentOS 6.7 on this machine ? It's simply impossible...

  • lbftlbft Member

    The port is not running properly (SATA II instead of SATA III) and offer lower performance that it should.

    SATA 2 has a maximum speed of 300 MB/s. That comes nowhere near explaining a drive running at 12.5 MB/s.

    I installed it via a rescue system.

    The support guy offered a full refund. Lets see if I will get it.

  • But how - there is no KVM, no graphics card :( Even if you move from different machine like XC SSD 2015 it boots, but disables network port immediately.

  • SATA II is limited to about 250 MB/s. You will never get 300 MB/s on SATA II. SATA III is limited to about 560 MB/s.

  • Which SSD's are you using ? Mine is SAMSUNG MZ7LN256HCHP-00000 256 GB.

  • WOW - I didn't try that. Just asked Online.net how are they doing and they've said still no progress. Looking at the CentOS 7 boot options like "baremetal" I thought it must be something special to be able to boot.

  • FreeBSD is gone in the installer ;(

    [Bumping thread]

    Out of interest, has anyone here gotten BIOS updates (or fixes) yet, or are the issues just being palmed off?
    I haven't bothered following up with Online.net yet, but just wanted to know.

  • mkln0mkln0 Member

    I'm getting around 65MB/s disk speeds on a XC 2016 sata. It's kind of slow, I'm also guessing it will be throttling the [average] download speed?

  • awvnxawvnx Member

    I don't see how SATA II vs III is an issue here since there's no way a cheap 7200 rpm drive can get anywhere close to saturating SATA II anyway. Perhaps they mean there's a bug in SATA in general that's slowing it down to 10% of what SATA II could achieve...

    Thanked by 1lbft
  • mkln0mkln0 Member

    65MB/s is around half of what I'd say is reasonable to expect. I usually get 170-180 on other sata servers.

    Any word on limited editions ?

    Some of the last dates were:

    18.03.2015
    06.04.2015
    29.09.2015
    26.11.2015
    25.02.2016
    

    So we might expect something very soon ;)

  • Still being palmed off by support, no update yet despite them saying they were expecting a fix over a month ago.

  • Still nothing...

  • hawchawc Member

    @abermingham this, plus the network issues some XCs are having really isn't good. Any progress?

    Tested in the wrong directory.

  • ^ Thread is about the 2016 model, not 2015, but those speeds don't look like a disk (SSD or HDD). I'm guessing your /tmp partition is mounted as tmpfs or similar.

    Your right it was, oops.

    As to the models, I was aware, just thought it might be useful to have a data point from a 2015 model.
