Demonstrate a repeatable model for establishing XrootD servers at SRC sites

• • We believe that, to establish consistency between sites, we need a repeatable deployable model for being able to transfer data between sites
• Test – To test this, we will establish a set of scripts / instructions that can be used with minimal additional guidance or intervention for the installation and configuration of XrootD.
• Metrics – As close to a green-field site as is possible will be able to configure XrootD with minimal reference back to the originator of the instructions.
• Success Criteria – We will measure the success of this if, following installation of the XrootD, a site can successfully transfer data to and receive data from another site.
• Timebox – The hypothesis will be established a tested within PI-21
• Lessons learned – From this exercise, we will have learnt to what extent a standard set of instructions on how to set up a site can be created and to identify where site-specific modifications to these instructions is likely to be required.
Minimum Viable Product*
• Successful installation of XrootD, using a repeatable set of instructions, to establish an operational file transfer capability capable of sending and receiving SKAO-like data to and from sites.

A standard set of instructions on how to set up a site will have been created.
The need for any site-specific modifications to these instructions will be identified.

Business Outcome
• A repeatable process for setting up a site for the purposes of data transfers will have been successfully demonstrated
• The need for site-specific configuration will have been established

Leading Indicators
• XrootD can be successfully installed at Cambridge using the instructions already created by RAL
