Multiple smart array P400 controller on DL580 G5

Hi,
is possible to install two smart array P400 controller on DL580 G5 server?
This is for performance improvement, I have only 4 physical disks, but I want to balance the load between them.

Thanks

Yes you can install multible RAID controllers.

I don't believe you will get a lot of performance from that.

Are You using seperate disks, or are you using RAID?
What RAID level?

Accept or Kudo

Now I'm using 4 physical drives configured as 2 logical drive (RAID1).
My application writes two kind of data:
1) local database data (ctree),
2) log data.
I want to separate them by using 2 controller, do you think I don't get more performance from this action?

Thanks

Yes It is.

But you can utilized the second channel of your P400. Bay 1-4 is using the first channel, bay 5-8 used second channel.

Since you have only 4 Disks, better to put two HDD in Bay 1 and 2 (configured as Raid1+0)and the other two to Bay 5 and 6 (configured as Raid1+0).

No need to install additional Array Controller.

Is there a way to see controller cache statistics?
I want to know if the amount of cache installed is enough for my application.

Thanks
