Hydra Upgrade: Upgrade virtual to accommodate native drive workload • New 8 Gbps FICON provides the capability to consolidate devices • Use GRID to make second copy of former native tape workload to eliminate the need for Iron Mountain • Use Hydra cartridge export facility if physical tape copies are required 2. Use Hydra as a C07 replacement • Add physical tape to virtual environment for enhanced scaling and economics • Use Hydra cartridge export facility to create off-site cartridges 3592-C07 Controller Tape Tape Tape Traditional use cases for z/OS Native Tape Use Case Solution Customer Benefits • • • Most clients utilize native tape simply due to the high performance of today’s native drives or for export. Today with 8 GB FICON, these workloads can directed to a TS7700 and replicated using GRID or sent to a TS7720T with copy export.
