DL380G3 5i+ & 6402 best combination???

[peanutno1]

I have a DL380G3 with a SMART 5i+ controller in integrated duplex mode.
x6 Ultra 320 drives, 2 boot the os (W2K3) on port a, and 4 are on port b for data.
I have since installed a 6402 controller (128mb) as the 5i+ is downgrading the 320 drives to 160mbps. I have moved the data drives onto the 6402 and have left the os drives on the 5i+, this being the boot controller still.
Due to this configuration I can still keep the system in duplex modem (now PCI Duplex), otherwise all the drives would have been installed on the 6402 in PCI simplex mode.
All has been detected ok after running F9, and deleting the failed drives, and all the data is in tact.

Could you please let me know if this is an ideal configuration, or should all the drives be put on the 6402 in simplex mode?

I was taking the route of fault tolerance/resilience.

Please advise
thanks

I don't think there is any problem with your config. Having an integrated controller looking after internal disks and a pci controller handling external disks. This isn't quite what you have but the point I am making is 2 controllers in a system is not uncommon. If you are happy with the slower performance on your OS disks then there is no problem.

On the subject of fault tolerance, if the integrated controller goes down your data will still be unavailable, though of course you will have the option of moving your os disks to the pci controller and rebooting.

thanks for the reply much appreciated!
This is good news!
I have put in place two of my DL380G3's like this config, and they are working fine.
I guess also the fault tolerance would work the other way too? If the 6402 failed, I could put the other drives back onto the 5i+ integrated controller?
Both controller's have battery backed cache.
