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.

Network-attachable, file-accessible storage drive

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.
