I/O Scheduler HDD/SSD mixed environment

Create a UDEV rule to setup the I/O scheduler:

/etc/udev/rules.d/60-schedulers.rules

# set deadline scheduler for non-rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="deadline"

Swap Space on SSDs

The following is a recommended tweak for SSDs using a swap partition that will reduce the "swappiness" of the system thus avoiding writes to swap:

/etc/sysctl.d/99-sysctl.conf

vm.swappiness=1
vm.vfs_cache_pressure=50
