Reducing our power footprint

In DIT we are always looking for improvements in power management for our large fleet of servers. The latest round of infrastructure refreshes has focused on replacement Oracle hardware, superseding the legacy Oracle (previously Sun Microsystems) hardware that powered databases like Banner and Alesco. Although the databases have moved to new machines, the code that powers a lot of the processes behind the scenes still resides on this hardware.

Moving off the legacy hardware reduces the power footprint for our datacentres as the new servers are smaller and much more efficient. It also enables us to reduce costs and increase the resilience of our services.

The graphs below show the significant power savings of over 800 watts per site.
