Description

Due to the increased demand of network traffic expected during the HL-LHC era, the T2 sites in the USA will be required to have 400Gbps of available bandwidth to their storage solution. 
With the above in mind we are pursuing a scale test of XRootD software when used to perform Third Party Copy transfers using the HTTP protocol. Our main objective is to understand the possible limitations in the software stack to achieve the target transfer rate;  to that end we have set up a testbed of multiple XRootD servers in both UCSD and Caltech which are connected through a dedicated link capable of 400Gbps end-to-end.
Building upon our experience deploying containerized XRootD servers we use docker and kubernetes to easily deploy and test different configurations of our testbed. 
In this work we will present our experience doing these tests and the lessons learned.
