Hardware Raid Questions

[ooskay]

Hi all.
I have a asus p7p55d mainboard and its inside have intel raid controler, also i found an hp smart array 641 controler from my friend.

Booth of them are seems not working raid options as properly with proxmox 1.5
(from on intel main board i can access to disk as ide type.)

is there have anyway to use that two card on my pc with proxmox?

Probably (I'm sure about onboard Intel) both are Fake-RAID controllers. It means that its software RAID but managed via drivers. I'd recommend using linux software RAID and LVM on top of it. Performance would be the same (if not better on linux) and you'd have few advantages - such as management from linux cli or if case of mainboard failure you wouldn't have to use exact same one (as in Fake-RAID). Also you can access those data on ANY Linux environment afterwards.

I'd recommend also using SATA controller in AHCI mode (f.e. NCQ and P&P support). In that case there is no need to use external raid cards unless it's not REAL hardware RAID or you used up all ports on your motherboard.
