Hello Cephers .
I wonder if anyone has some experience with full ssd cluster .
We're testing ceph ( "firefly" ) with 4 nodes ( supermicro
SYS-F628R3-R72BPT ) * 1TB SSD , total of 12 osds .
Our network is 10 gig .
We used the ceph_deploy for installation with all defaults ( followed ceph
documentation for integration with open-stack )
As much as we understand there is no need to enable the rbd cache as we're
running on full ssd .
bench marking the cluster shows very poor performance write but mostly read
( clients are open-stack but also vmware instances ) .
any input is much appreciated ( especially want to know which parameter is
crucial for read performance in full ssd cluster )
Thanks in Advance
