TMK, an array built with an HP Smart Array controller can be recovered on any other HP Smart Array controller, the same or newer. I would not expect to recover on anything else.
I gather Dell have a very poor reputation in this regard. The point holds, however, MAKE SURE you can recover from a broken hardware raid controller, some you can, some you can't.
Over the last 10-12 years I have moved enough arrays around across HP Smart Array Controllers to know it'll work. It just does. Chapeau!, HP
What is the main advantage of hardware RAID over software RAID on Linux? (I think performance and that a hardware RAID can automatically boot from the second disk, but I am a newbie in hardware RAID and so not sure.) Offloading to hardware is always about speed and less load on the CPU. Thanks, Peter and Peter.
So I will go for software RAID. The server is an backup server which runs backup jobs over night. Even RAID is not necessary, but on the wish-list. Disk performance is not so important. Most of the CPU power will be needed for the LUKS AES encryption and for the SSH/VPN/Rsync operations.
I thought, that the server can run some days with a broken disks until I go to the server location and replace the disk.
Raid 1? Make sure if you intend to run with broken disks that you have a 3-way mirror. I'd rather run raid-6 ...
Yeah. The bigger the disk, the bigger the risk. -- Per Jessen, Zürich (18.1°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
