Hi,
I am trying to set up my first webserver. I bought a Dell
Poweredge 860, provided with a SAS5/IR RAID-Controller.
The problem is now, that I cannot find software, that monitors the
state of my disks. I already tried megarc from the ports but all I
get is a short answer that no adapters where found:

I had emails with Dell and LSI. Dell does not support FreeBSD and
LSI says I should go and ask Dell ...
The second thing is, the perfomance.

Final score for writes: 16
Final score for reads : 2025

That is pretty poor, isn't it ?
I am wondering now, if somebody has experience with the PERC5/I
Controller. Would it be possible to monitor the disks, if I would
buy that controller ?
Any hints are highly appreciated.
Thanks
Michael
I don't know about monitoring the SAS5/I however I read some posts
on one of the lists that was talking about the linux compatibility
system providing all of the correct interface for the linux version
of ?megacli? to work on FreeBSD. As the SAS5/I is mpt driver based
could it not be checked with camcontrol? (Just an idea never tested).
As for performance issues with the SAS5/i, there is a problem in
the controller. A work arround was created by Scott Long which
created a sysctl that could be set to cause the controller to turn
on the on drive write cache's. These changes where commited to
RELENG_6 on 2007-06-05 21:32:57 UTC.
The PERC5/[ei] controllers do not suffer the performance problems
of the SAS5/i controller, we have ~30 systems with these
controllers and have never seen any performance problems with them
even when they have 20 drives attached to them.
Hi Tom,
thank you for your response. What about monitoring the PERC5/ie ?
Does it work with megarc or any program under FreeBSD ?
