server harddisk

[Christian Christmann]

Hi,

in the next days I want to install a Linux server.
This server should run 24/7. One question about
harddisks:
Somebody told me that S-ATA HD are not suitable
for a server because they are not supposed to
be run 24h every day. Instead this person
recommended me to use SCSI HDs which are more
reliable in this case. Is this true?
Or shouldn't I worry about using S-ATA harddisks
for my server?

Thank you for your answer.

Chris

I have 3 machines with SATA, they are running since the beginning
of the year, have been down for 2 hours when I moved them from one
machine room to another.

SCSI is in general more reliable than IDE or SATA and, if you get
the right hardware, they are hot-swappable, while there is no
hot-swap for IDE or SATA yet.

Agreed. I have experienced *far* fewer problems with SCSI drives than
I have with IDE. No experience with SATA, though.

Actually, quite a few manufacturers have hot-swap [E]IDE/SATA cages.

just as an example.

Yes, pity that the SATA drivers doesn't support hot-swap yet!

Dunno about Linux or UNICES, but my windows box at home is quite
happy when I hotplug the SATA drive. There is actually two of them
running in a RAID1 config. All I need to do then is to start the sync
by hand.

Sure?

Disks have no hot-pluggable carrier. It's the box I'm currently
typing, a desktop. There are just 2 SATA drives in RAID 1 mode,
but from the above and a short look at the manual, it looks like
those are perfectly hot-swappable, if you have the needed hot swap
carrier.
