I stumbeld over this hardware RAID system: Raidon We-Ra. SATAIII/SSD in IR2022
Can I use my gentoo system with such a hardware RAID? Are there any points I should consider.

Re: Hardware Raid
Chris1969,
Its a RAID1 system. I wouldn't count on it being hardware though.
If it appears as a single SATA drive, its a black box. You have no idea how the RAID is implemented.
Try it.

Re: Hardware Raid
Do you have a link to a handbook or description of this device?
I'v found a hardware box with two disk compartments. And you connect it with sata cable.
So if it is really a hardware raid, you should be able to access it from any decive connected to. For a laptop you something which would provide a sata connection.

Re: Hardware Raid
Thanks NeddySeagoon and Banana for your answers!
I only found this (probably I am not supposed to post any pdfs), so here's the link where you can find product sheets of the iR2022 and iR2024: http://www.raidon.com.tw/RAIDON2016/download.php
I wonder if it would work with two different ssd models?
Also with different hard drive capacities?

Re: Hardware Raid
Chris1969,
The HDD models won't matter.
With different drive capacities, RAID1 will be physically limited to the capacity of the smallest drive.
What happens with the wasted space on the larger driver is not specified.
As its an enclosure, it may matter where the small drive goes.
-- edit --
It offers both raid1 and raid0 but I didn't see any mention of JBOD (Just a Bunch of Drives) mode. Now I've read the manual, both modes are restricted by the size of the smallest drive.

Re: Hardware Raid
Thanks NeddySeagoon for sharing your knowledge with me!!
So if I understand/imply correct:
1. I could start using the RAID hardware with only my existing hard drive holding my gentoo system
2. add any other EMPTY harddrive big enough
3. the RAID hardware will duplicate/copy /backup on the second drive
4. if any of the two disk fails, the system runs from the remaining sane disk
5. until I replace the failed one with any disk big enough
6. If desired I could use any of the two disks to boot from outside the RAID hardware again?
