Hi all, I have installed ceph luminous, witch 5 nodes(45 OSD), each OSD server supports up to 16HD and I'm only using 9
I wanted to ask for help to improve IOPS performance since I have about 350 virtual machines of approximately 15 GB in size and I/O processes are very slow. You who recommend me? In the documentation of ceph recommend using SSD for the journal, my question is How many SSD do I have to enable per server so that the journals of the 9 OSDs can be separated into SSDs? I currently use ceph with OpenStack, on 11 servers with SO Debian Stretch: * 3 controller * 3 compute * 5 ceph-osd network: bond lacp 10GB RAM: 96GB HD: 9 disk SATA-3TB (bluestore) -- *Davis Mendoza P.*
