Gigabyte ga-ep45-ud3p raid

[xor]

I was told recently, by the tech team working on the datacenter I'm currently hosted in, that Proxmox doesn't support the onboard RAID card from GIGABYTE GA-EP45-UD3P. I'd like to know if this is a temporary matter that will be corrected soon with the next Linux kernel update, or if it's something permanent.

This is not a hardware raid controller. this is called 'fake raid' and will never supported on Proxmox VE.

For a good overview about raid I recommend this wiki article:

Is there a particular reason why Proxmox won't _ever_ support Firmware/driver-based RAID?
Is it impossible or unpractical?

Linux does not support it.

Linux does not support it.

That's not entirely true.

That's not entirely true.

As i know Linux support hardware RAID ant software RAID. But not integrated chipset raid

The goal of Proxmox VE is an easy to use high performance open source virtualiztation platform - host raid (and software raid) does not meet these requirements. and in some parts its also impossible.

All those fake/software raid features has major drawbacks.

1.) they have no hardware hotplug support
2.) configuration is complex an error prone (compared to HW RAID)

Together, these facts increases MTTR (mean time to repair), leading to less reliable system.
