HP Proliant ML150 G5 trouble with RAID1

[HellFire_MZ]

Hello all!
I've got 3 servers of that kind and all of them got the same problem.
I setted up a Windows 2003 Server R2 SP2, setted up all drivers, found some unknown devices - NULL INF management controller - setted them up.
My system uses HP Embedded Controller SATA with 4 Sata HDD -> 2 RAID-1, the first one is used by system, the second is for database.

I feel some freezes even when just I work on the console.
I made a performance test, everything is fine, except HDD.
Look at screenshot, i suppose it's not normal on RAID1 with SATA2 HDDs.
Help!

hi

does you server still have the unknown device?

what if you try enabling Write Cache for the Embedded SATA? have you done it?

bye
