Using Storage Spaces Mirrored SSDs as L2 Cache?

Post by Widdershins »

I have a use case of which I'd be content to use a storage spaces Mirrored volume (SSDs) as the L2 cache if it would actually afford additional data integrity to the L2 cache. Any reason why it would be a terrible idea or perform awful?

I see when I go to create L2 storage that all of my mirrored Windows "Storage Spaces" volumes are indeed presented as possible volumes for use as L2 cache.

If it's a matter of hardware keeping up, the workstations I'd be doing it on have 20 cores, 256GB RAM, and the SSDs are U.2 just a step below Optane in IOPs.

Disks created by Windows Storage Spaces are 4Kn drives. They are not supported to be L2 cache devices currently.
