We're now going through the process of updating the primary and secondary OA servers for Treaty 6 Education. We are using the rackmount HP servers with single Xeon / 4 drives mirrored/striped. The response of the servers is a little bit snappier than the older HP's we've been running for the last several years. I've installed the latest Debian Linux and are using Maria DB over MySQL previously. I've just completed the daily backups (using the backup perl script in the utility folder of the distro) both onsite and offsite backup of the complete OA system.... Databases, Files (all /opt/openadmin filesystem for 16 schools), as well as full Apache configuration, etc. In the event of a building burning down, etc. we could be back up in only a few hours.
I'm working on synchronizing all updated scripts (i.e. timetable scripts updated, etc.) so that I can come up with a new OA release, I'm calling 9.0. All schools on the new servers (primary server runs all 16 schools; secondary server has all previous years databases for querying as well as the onsite daily backups) are running this code. A new release should be along in a while.
