Cloud Storage for Data Protection and Long-Term Retention

Disk Library for mainframe (DLm) is an industry-leading virtual tape library (VTL) for IBM and Unisys mainframe computers. Unlike other leading VTLs for mainframes, DLm is a “disk-only” solution storing tape volume (VOLSER) images on disk storage attached to the DLm virtual tape emulation. DLm does not use or provide support for traditional robotic tape libraries and does not store VOLSERs on physical cartridge tape. DLm’s unique advantage is in providing deduplication and / or fast access storage as well as a higher availability architecture vs. other Virtual Tape offerings.
