We are testing an experimental Ceph cluster with server and controller at subject.
The controller have not an HBA mode, but only a 'NonRAID' mode, come sort of 'auto RAID0' configuration. We are using SSD SATA disks (MICRON MTFDDAK480TDT) that perform very well, and SAS HDD disks (SEAGATE ST8000NM014A) that instead perform very bad (particulary, very low IOPS). There's some hint for disk/controller configuration/optimization?
