I plan to install openSUSE Leap 42.2 on a HPE ProLiant MicroServer Gen8.
I have too options to setup RAID 1 on for the disks: 1) Linux software RAID 2) Hardware RAID with the embedded HPE Dynamic Smart Array B120i Controller
I want to be prepared for a possible hardware error.
I am familiar with software RAID. Even if the mainboard breaks I can take one or both disks to another computer and recover the data with any Linux system.
But how is it with the hardware RAID (B120i controller here)? If the mainboard/CPU/controller/whatever breaks, can I use the same strategy (take the disks to another PC without hardware RAID, recover data) or do I need to buy another HPE ProLiant MicroServer Gen8 or compatible server and recover the disks there?
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.
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. -- Per Jessen, Zürich (21.3°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
