  • An IBM Elastic Storage service providing 3,400 TB of storage and 40 to 50 GB/s bandwidth for project storage
  • An IBM Elastic Storage service providing 1,000 TB of storage and 100 GB/s bandwidth for global scratch
  • local disk storage on each compute node
  • One IBM 3584 tape robot:
    • 16 LTO tape drives
