Executive summary

This decision seeks approval to purchase new servers to be installed in the TfL data centre that is used by the GLA as a disaster recovery site. The installation of the new servers will increase the reliability and performance of the disaster recovery site. Importantly, it will also enable the GLA to start using the TfL data centre to provide live services (rather than simply being a backup site). This will improve the speed and reliability of GLA services since the TfL data centre is superior to the server room in City Hall. It will also reduce the need for planned downtime (for maintenance) of servers in City Hall since services can be easily moved back and forth between City Hall and the TfL data centre.

The current servers in the TfL data centre will be re-used for other purposes.
