Storage Spaces Config with JBOD

[mcvosi]

I have a 24 disk enclosure that I want to configure to use Storage Spaces. I will have multiple disk repositories in a scale-out repo. For the drive pool, is it best to configure a handful of disks, or one big pool? My thoughts are that it would be safer to carve out a few, in case of multiple drive failures. I will be storing my backup copy data on this enclosure.

TIA!

Hello,
off topic, but what about using RAID and going the way that is proven to work? I mean a proper RAID controller with write cache. I miss write cache in your hardware description.

Redundancy for storage spaces is configured on the virtual disk level. I recommend at least double-parity (which will probably make it slow compared to a proper RAID controller).

https://www.virtualtothecore.com/an-exa ... dows-2016/ describes a setup that sounds similar to yours. I would test how long a rebuild takes if a disk fails and probably just stick to normal RAID-6 recommendations (depending on the RAID controller vendor)

Summary: I would invest in a proper RAID controller.

Best regards,
Hannes

Yes, all I currently have are LSI SAS2 and an Avago SAS3 controller, which don't do RAID, to my knowledge. Recommendations?

Edit: I stand corrected, I see these do in fact do RAID.
