Tape library sharing among OSs - Logical Library function (option)

The Logical Library function(*Note 1) sub-divides tape drives and cartridge slots (cells) in a single tape library, allowing them to be seen as multiple libraries capable of use by different OSs.

*Note 1: The Logical Library function is an option of LT260 and LT270 S2.

Challenges

  • Ability to integrate back ups performed independently for each system in a multi-system environment.
  • Manage tape operation within a single tape library used across a heterogeneous server environment.
Logical Library function

Although the above system appears to be using different tape libraries, each OS environment is actually using the same single library that has been divided into four logical sub-libraries.

*Note 2: The supported backup software for ETERNUS LT270 can be used unchanged when using the Logical Library function. Also, the logical library has no effect on the interoperability of ETERNUS LT260 and LT270 S2.

Benefit

  • One LT270 S2 tape storage system can use up to 4 systems and one LT260 tape storage system can use up to 20 systems. This feature reduces both physical space and management cost, as well as, centralizing tape cartridge management.

Product Requirements

Supported Tape Libraries LT40 S2(*Note 3), LT40 S2(*Note 3), LT260, LT270 S2, LT250, LT270

*Note 3: LT40 S2, LT60 S2 are available by purchasing the licence for adding slots.
