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. I attached the output of blogbench:

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
