I am setting up a machine to act as an LTSP server for my church.  I have a
stack of old IDE hard drives that I want to use in a RAID configuration. The

slots.  I would like to get two PCI IDE controller cards to connect all the
drives with.  The server has an IDE CD-ROM, leaving 3 open slots in the
on-board controllers.  If I get two more cards (eah with two connectors), I
should be able to connect 8 more hard drives.

fun ..  that would normally be 8x 400GB of disk space :-)

Wouldn't that be nice.  If yo uare interested in donating the drives to my
church, let me know and I will give you the address :-)

I would like to use inexpensive cards (~$15-$30) since I will be setting up
software RAID and this is an older server with older drives. I have experience
with certain Promise cards under Linux (and I am not happy with that

what was the problem ?? which model .. where did you get it ..
	- i think all parts should be bought at pc-parts-distributors
	(reseller permit required) and not "me-too-virtual-web-stores"

I don't recall specifically (it has been over 2 years now). I remember that it
was a PDC202XX, and it was an on-board deal (Gigabyte motherboard).  It was
quite flaky.  It eventually failed and nuked the two drives connected to it.

why is promise not good ??? just the plain ole ide controller
	- it is the same as maxtor ide controllers too
	( same promise chip )

I was using it for the RAID.  However, at the time I was not aware that the
kernel software RAID functionality was superior and the setup was inherited
from a previous admin who was a Red Hat fanboy.

their hw raid controllers suck .. but what do you expect for under $2000
hw raid controllers .. one gets what one pays for ??

True.  However, I didn't pay for it, so I had no say in the matter.

- don't ever use the motherboard bios based raid if your data
 is important to you

Please see above comments :-)

- in my book, here is no other ide-chipset i would use when we ship off
 to customers .. if you wanna pay $200 - $400 for 3ware .. i suppose
 thats an option too .. but why .. for sw raid

more raid fun

what the raid performance result should look like

Maybe I was not clear in the way I stated myself.  I want a controller to use
only to connect some IDE drives.  I don't care (or really want) hardware RAID
functionality.  I am planning on using the software RAID functionailyt
available from the kernel.
