    IDE VS SATA server

    Hi,

    I have ordered a dedicated server SATA Xeon but got IDE Xeon. Should I contact my datacenter to change the server or is ide and sata the same thing and it does not make a real difference.

    Thanks

    IDE and SATA will refer to the type of hard disks used, Xeon will be the CPU.

    They are different, if you purchased SATA you should recieve SATA

    I thought that drive is Ide but my datacenter is claiming that it is sata though. The way that I figured that the drive is ide is that in the server information link in whm it shows all partitions as:

    /dev/hda2

    But in my other server which I for sure know that it is sata it shows:

    /dev/sda1

    Is that a method on how to check if you have ide drive or sata?
    I am assuming that sata drives are faster which means it is better to have sata drive.

    SATAs have been around for sometime so it is unlikely that the servers is using IDE, actually I think its more expensive for IDE these days since its old technology.

    Install lshw this'll give you all the information you need about your hardware

    You are right, Usually a hard drive that starts with hd* is an IDE, and sd* is a SCSI device. Ask the host how many pins are on the connector for the hard drive data cable.

    SATA drive are faster then IDE in most all cases.

    Certain SATA chipsets (I don't know of any offhand, but I know I've seen them and been like WT%?!) show up as hd*... Might be something to look into. You're more limited by the RPM of the drive than the interface anyway, in most cases you won't see a difference unless you're moving larger files that can take advantage of the higher transfer rates. Seek and access times, etc should be very similar.

    It's a bit fishy... as unless there's a BIOS setting wrong, or a poorly configured kernel, your SATA device should show up as a /dev/sd# device.

    Have the Datacenter check the bios to make sure the drive support options don't have anything like "Compatability" mode SATA support set.

    True, emulation modes in the BIOS might be affecting it... An easier way to figure it out is to just look at the model of the drive in /proc...

    you have hdparm program install? You can do test run with -t or -T . You can see the different between ide and sata based on the transfer rate.

    if the OS sees it as IDE, hdparm will give IDE performace result even it's a SATA HDD. So use dmesg to check with the model and if it's SATA HDD ask the DC to correct the settings in the BIOS.
