I have a FreeBSD 10.0 server which currently only runs Percona MySQL server 5.6 backed by ZFS. The SQL server doesn’t have a high enough load to justify dedicated hardware, but I also don’t want to run it as a virtual machine as I want to use local ZFS storage, and because of virtualization overhead. The server is dual-homed (DMZ and LAN).
The solution is to convert the server into a jail host, and run MySQL inside a jail. The overhead should be minimal to non-existing as I won’t be using VNET.
