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)
