I use this iso of Proxmox.
Can Proxmox be installed in hardware RAID1?

Hello,

THis is not hardware raid, this is a software based raid solution, what require its own drivers. Dont use this, create softraid in Linux.

Why this is software raid? Are you sure?
I made this raid in BIOS, my mother board have RAID, please check specification (in google: fujitsu e900 e90 pdf, I can't post a link)

This is your suggestions, right?
1. Dissable RAID in BIOS
2. Install Debian with software RAID1
3. Install Proxmox

What about with a server with only 8 GB Ram and 2 x 1 TB SATA 7.2k drives?? ZFS Raid 1 and limit RAM used by ZFS?.

Purpose is run only a VM and make backups with Proxmox to NFS Share and can move to other cluster if we need run maintenance tasks on physical node.

hi optimistic,
as people pointed out already BIOS raid is not a real raid.
there are only a handful of MB with a real hardware raid controller on board. most of the MB have so called fake raid which is not supported my most OSes. and it will create a headache for you if something go wrong later on or if drive fails and need to be replaced.

you have 2 options:
option 1 : if you really want real hardware raid, you will need to search for a real good quality controller sported by Debian/Proxmox. you can ask on the forum and someone will give you models that work. but be ready for sticker shock.

option 2 : use ZFS mirror (raid1) mode instead as this is the only one I know works with Proxmox.
or you can load Core Debian using mdadm raid and try to install Proxmox on it. not sure if it works though.

BTW, ZFS mirror works great.

Thanks a lot to everyone.
Now I know what if fake RAID :)

I chose Debain+mdadm.
Yes, I saw that it can be some issues, but I don't have much RAM for ZFS.
