Thank you, Ajay.
That's useful to me.
And do you know if the 3ware ATA raid card
(7006-2 or 7506-4LP I suppose) flushes the disks in case of power failure or do
they just forget the buffered datas so that the filesystem crashes afterwards ?
(i.e. do they have a capacitor to hold the datas up to the moment they are all
written). I will have a remote reboot (power failure like) that I might use
quite often and I know this is no problems with ext3 filesystem on 1 IDE disk
only (I made some tests), but is it the same reliability with this 3ware
raid card for power failures ?
Thanks a lot for sharing your experience
!
Daniel

If you could share me your experience it would be great.

I haven't checked recently, but the last time I played with any
promise
controller it was a train wreck. I then picked up a 3ware
ATA RAID card
and never looked back. It's well supported as the
drivers are in the
main kernel tree since 2.4. So you install your
drives, setup the ATA
raid array in the 3ware bios and when you boot up
it's detected as a
SCSI device. It's the easiest solution out there,
so IMO, it's well
worth the extra
money.
