Sorry if my reply came so late....

First let me do some clarifications:

My configuration is far simple from the one you described above.... i
got only 4 disks(3 data ,1 parity) on 2 IDE-channels.

Now.

I tried with the script you suggested and...

1) I'm pretty convinced that RaidFrame is not guilty.
2) The problem is something IDE related.:)

Now i'm wondering if it was an hardware related problem.

What kind of performance can i expect when i make simultaneous access on
4 disks connected to 2 IDE channel?

I'm using on-board IDE-controllers of my motherboard.

I netbooted my machine and started the following script fron nfs-root:

#!/bin/sh

for i in 0 1 2 3
do
        dd if=/dev/rwd${i}e of=/dev/null bs=1m count=5000 &
done

the result was that the network has gone,and didn't came back(i have to
reboot).:(

But using a 3com network card instead of RealTek one i got:

5000+0 records in
5000+0 records out
5242880000 bytes transferred in 573 secs (9149877 bytes/sec)
5000+0 records in
5000+0 records out
5242880000 bytes transferred in 573 secs (9149877 bytes/sec)
5000+0 records in
5000+0 records out
5242880000 bytes transferred in 1270 secs (4128251 bytes/sec)
5000+0 records in
5000+0 records out
5242880000 bytes transferred in 1271 secs (4125003 bytes/sec)
Is it normal?

In few words ,it's possible make a raid 5 array using on-board IDE
controllers?

Thank You!
