Virtual tape access using modern storage

Concept

VTA acts as a virtual tape controller, allowing MVS & VSE to read/write tape datasets to NAS/SAN/RAID without changing applications.

  • Transparent to OS & applications
  • Emulates IBM 3490E tape drives
  • Works with or without tape management

Benefits

  • Fewer physical mounts & devices
  • Reduced floor space and media handling
  • Improved backup/restore and DR workflows
