<DIV><FONT face=Arial size=2>That's useful to me.</FONT></DIV>
<DIV><FONT face=Arial size=2>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 ?</FONT></DIV>
