Yah, I had wondered that. Also  it seems to involve a lot of manual tinkering with the crush map which I really want to avoid.

 


Also given your setup, you should be able to saturate your network now, so
probably negating the need for super fast storage to some extent.


Agreed - now I have it installed and configured, performance all round has vastly improved - user are already commenting that their VM's are much more responsive.

Pretty sure that we are now at a stage where I can just leave it alone :)

Though the boss now wants to migrate the big ass vsphere server to proxmox (KVM), so I could use it as a third OSD server ,,,


Thanks for the help, much appreciated,
