Message-ID: <200501161628.23034.mlaks@verizon.net> (raw)
Thank you to Gordon, Maarten and Guy for your helpful responses. I learned
much from each of your comments.
Maarten: I paid $70 for an antec sl450 power supply. seems better price than
you are saying ( is your power supply better?). Also I liked the idea of 6
+3+3 slots on your box, but i dont see it for sale in the us.
Gordon: I get the same output on 2.6.8 sarge kernel for hpt366 driver. I
notice that running
hdparm /dev/hde
that the IO_support is set at default 16 bit while on the other hard drive
on the natice ide bus
/dev/hdb
has IO_support at 32bit.
I wondered if I get the other driver whether that will improve things...

I notice that according to the man page the settings you describe are the
defaults. Why did you have to adjust them?
Moreover When I cat
/proc/sys/dev/raid/speed_limit_max -> i get ->200000
/proc/sys/dev/raid/speed_limit_min -> i get -> 1000.
interesting is i didnt adjust them up myself.... Should I adjust the
speed+limit_max down to 100000???
I wonder where in debian it got adjusted up?
Thanks
