Hi everyone, I'm trying to figure out what is the best OSD solution with an infrastructure made up of servers with a lot a disks in each. Say, for exemple you have 4+ nodes like Sun Fire X4500 (code-named Thumper). Each node is 48 disks. What are the pros and cons to build a ceph cluster with btrfs on that kind of high density hardware, considering the different scenarios for each server : - 1 OSD daemon per disk, so 48 osd daemons per server - make 3 btrfs pools of 16 disks, so 3 osd daemons per server - make 3 raid 5 or 6 volumes, so 3 osd daemons per server >From a performance and management point of view, will you recommand a lot of small servers of a few numbers of thumper's like servers ?
