The Scientific Data and Computing Center is migrating part of its 200 PB tape-resident data archive to new high-density robotic libraries. The talk will focus on the product/vendor evaluation process and the complex of decision criteria observed. We will also discuss the potential implications of moving from high-performance to high-density robotic systems for hosting active data archives.
The presentation shows the Storage test bed set up that I implemented in 2018/2019 when working at SLAC
to meet the 2020 LCLS2 data reduction pipeline requirements reaching 100GB/s.
This set up is primarily oriented on high performance rather than high availability and is based on Lustre/ZFS with NVMe SSD storage and EDR Infiniband connection between Object Storage Servers and clients...
