Have you tried Ceph? Seems purpose built for just that sort of setup (metadata on NVMe, data on spinning). I've been watching it for years, but only recently set up a test, and it worked well even through a power failure at home. My previous company had been using it after I left, and they seemed happy with it, but I haven't asked too much about it. I'd like to start doing some testing with it at work.
- edude03 5y agoI am currently running ceph actually! Out of the box, only having NVME in my storage pool, with 100GB interconnects, I'm getting about 50Mbit/s in Fio write tests. I'm not a storage expert, or a ceph expert clearly, but so far of the options I've tried (Portworx, Rancher) it's the worst performing, and I don't know why.
