if your chipset is not listed ... you're gonna have some fun
lsi or adaptec chipset based controllers would be my choice
if you want to make ide look like scsi drives
- 3ware escolades works good when properly configured
( but dont try hot-swp ...
i prefer software ide raid, and use the extra $$$ saved on
hw raid controller on extra servers and extra disks instead
- raid1 is worthless for stuff i do ...
- raid5 is okay when you have 2 independent raid5 arrays
- i build raid for large data storage .. not necessarily
speed and thruput ... though it has to be fast enough
and NOT noticeably slow
testing your raid setup
- unplug /dev/sda or /dev/hda
- it should still keep working and see if you got
any error messages that your raid is not longer
- repeat for each drive including replacing with
a virgin disk
- right now you can get maxtor 8MB buffer 7200rpm 160GB ide disks
for $80 each at "fries"
-- 5x $ 80 --> $400 in disks for 800GB of space !!!
try building that raid subsystem capacity with scsi ... :-)
more raid fun
