When we use SSD disks for installation of OpenStack/Ceph we need to use more optimized parameters to get normal performance.

1. Need to set disks scheduler to 'noop' for SSD disks:
echo "noop" >> /sys/block/<disk>/queue/scheduler

2. Mount it with the following options:
rw,noexec,inode64,logbsize=256k,delaylog,nodev,noatime,nodiratime,user_xattr,data=writeback,barrier=0
