Intivity Releases Open Source Tape Management with Mainframe-class Features

Share Article

REELlibrarian released as open source Intivity TMS software.

Intivity Corporation today announced the availability of Intivity TMS, an open source tape management system (TMS) designed to bring tape and other sequential media access features previously only available in mainframe environments to distributed systems. (

Intivity TMS, formerly sold as REELlibrarian and Cray Librarian, has been released as an open source product under the GNU general public license. Intivity TMS provides the ability to write and read cataloged data sets (files) on tape, including the ability to import and read or write ANSI and IBM labeled tape formats. Intivity TMS can share the tape library resources with other applications and handles all of the complexities of scratch tape allocation, robotic control, and matching media with compatible drives in mixed media environments -- effectively abstracting the tape library resources into a distributed, flat, SAN-accessible namespace. With Intivity TMS, any application which can read or write a pipe can access data on tape.

"Despite rumors to the contrary, tape and sequential media will form an essential storage tier at large companies for many years to come," said Mark Roberts, president of Intivity. "Intivity TMS addresses the needs of companies managing rapidly growing data repositories in tape libraries in the areas of data protection, archival, and data managed by legacy applications."

Though full-featured tape management has long been available in mainframe systems, "no such capability has been widely available for enterprise open systems environments," said John Groves, Intivity's chief technology officer, adding that "although disk prices continue to plummet, tape and other sequential media still provide significant benefits and cost savings for long term storage and archival."

Intivity TMS features include library inventory tracking with complete audit trail, tracking of off-site vaults, standard and customizable reporting, support for pooling to ensure scratch tape availability, and utilities for controlling tape and catalog maintenance activities.

Intivity TMS features include:

+ Operates with open and mainframe systems

+ Full SAN support for distributed and clustered nodes

+ Global flat name space

+ All applications and users can share the ATL resources

+ Applications need no intelligence with regard to tape I/O, EOT handling, or ATL operation

+ Can read/write and convert legacy-format tapes, including ANSI and IBM labels as well as tar, cpio and raw formats

+ Self-identifying on-media labels

+ Meta-data implemented in a database for scalability

+ Rich attributes for retention, location, and technology

+ Unlimited file sizes

+ Dynamic allocation of storage

+ Agnostic with respect to storage devices

+ Cataloging, media management and vault management for removable media

+ Media reclamation and transcription

Intivity TMS is currently available under moderated release from Intivity's Web site.
