The NERSC division of LBNL has been running HPSS in production since 1998. The archive is quite popular with roughly 100TB IO every day from the ~6000 scientists that use the NERSC facility. We maintain a Globus-HPSS endpoint that transfers over 1PB / month of data into and out of HPSS. Getting Globus and HPSS to mesh well can be challenging. This talk gives an overview of some of the lessons learned.

In this paper we explain how to obtain and install HSI, create a NERSC authentication token, and transfer data to and from the system. Additionally we describe methods to optimize data transfers and avoid common pitfalls that can degrade data transfers and storage system performance.
