  • Publication number: 20070130477
    Abstract: Data stored on a removable storage medium such as a tape cartridge can be protected from unauthorized access by storing a password hash value in a protected manner on the storage medium, where the password hash value is generated from a password by a one-way hash function such as SHA-256, so that the password cannot easily be determined from the hash value. A media drive is then equipped with logic for blocking access to the data unless the password is provided. The password is protected from unauthorized access because the password hash value, not the password itself, is stored on the storage medium.

  • Publication number: 20070067364
    Abstract: Storage drive logic and a standalone tape file structure are described. File transfer logic transfers file data to and from a network according to a first protocol. Media access logic accesses a sequential-access storage medium associated with the drive according to a second protocol. Media management logic translates file-based commands received from the network according to the first protocol into sequential-access device commands according to the second protocol. The device commands control accessing of data by the drive. The storage medium may be a magnetic tape including a data region for storing data in a file format, and a table of contents (TOC) region for storing a table of contents that indexes the locations of files within the data region.

  • Publication number: 20050052772
    Abstract: A system and method of operating a storage system is provided. The storage system includes a tape cartridge having a magnetic tape medium and a tape drive for reading and writing data to the magnetic tape medium of the tape cartridge. Performance data associated with specific operating loci (e.g., bands, directions, tracks, segments, etc.) of the tape drive and tape medium are collected, analyzed, and stored, allowing for analysis and detection of trends over time. In one example, tape usage events are monitored and when they cross a threshold the system may remove particular tapes in a preventative maintenance approach to reduce system outage. Performance data is collected and analyzed with a portion of the performance data being saved to emulated medium auxiliary memory (EMAM) on the magnetic tape, and a portion of the of the performance data saved in non-volatile storage in the drive.
