IDE VS SATA server
| Posted by Manageandsupport_com, 03-06-2008, 12:34 PM |
| 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.

| particular 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.
