If you are careful about how you balance things, there's probably no
reason why SSDs and Spinners in the same server wouldn't work so long as
they are not in the same pool. I imagine that recommendation is
probably to keep things simple and have folks avoid designing unbalanced
systems.

I don't know the official reason, but I would imagine the disparity in
performance would lead to weird behaviors and very spiky overall
performance. I would think that running a mix of SSD and HDD OSDs in the
same pool would be frowned upon, not just the same server.

Can you please elaborate more why running SSD and HD based OSDs in the same
server is not
recommended ?
Thanks

It'll be used as OSD+Mon server only.
Are these SSDs Intel S3700
Thanks for your answers; mine are inline, too.

Are these SSDs Intel S3700 too? What amount of RAM?
