If feasible, I would simply go NVMe as it sounds like you will be using this disk to store the journal or db partition. IF there’s an avalable PCI slot. And then you have N OSDs dependent on a single device, so when it flakes you lose the whole node. One thing that consumer SSDs — and even some that pretend to be “enterprise” — experience is performance cliffing, they look okay with light workload, but at some threshold they saturate and plummet. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
