Solution Overview

Problem

Existing mechanical pass-through connections for transferring data between magnetic tape libraries are prone to mechanical wear, defects, high maintenance costs, limited flexibility, and require compatible library types, leading to scalability issues and data loss.

Innovation Solution

A computer-implemented method and system that enables data transfer between magnetic tape libraries via a network connection, using data transfer management components to initiate mounting, copying, and deletion of data between magnetic tape drives, allowing for flexible configuration and operation across different library types and locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical pass-through connections are used to transfer data between magnetic tape libraries, then data transfer between libraries is enabled, but mechanical wear and defects occur leading to high maintenance costs and reliability issues

Engineering Contradiction:

ImprovereliabilityVSAvoidmaintenance costs

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces mechanical pass-through connections with an electronic data transfer system. Magnetic tape drives in source and target libraries connect via a network (e.g., Fibre Channel, Ethernet) to transfer data electronically. This eliminates mechanical wear, defects, and associated maintenance costs while improving reliability and enabling flexible library-to-library data transfer without physical cartridge movement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If mechanical transport systems are used to connect multiple libraries, then data transfer between libraries is achieved, but the system becomes complex and difficult to manage

Engineering Contradiction:

ImproveflexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical transport systems with a network-based electronic data transfer system. Magnetic tape drives connect through standard network infrastructure, eliminating the need for mechanical tunnels, robots, and synchronization mechanisms. This reduces system complexity while maintaining flexibility in connecting different library types and locations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent enables magnetic tape drives from different library types and vendors to interoperate through standard network protocols. The electronic data transfer system is universally compatible across various library platforms, eliminating the need for proprietary mechanical connections and enabling flexible integration of heterogeneous storage systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If libraries are installed at the same location for mechanical transport, then reliable mechanical connection is achieved, but space availability and scalability are limited

Engineering Contradiction:

Improveconnection reliabilityVSAvoidscalability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces location-dependent mechanical connections with network-based electronic data transfer. Magnetic tape drives can exchange data over standard network infrastructure regardless of physical distance or location. This enables libraries to be distributed across different data centers or sites while maintaining reliable data transfer, thereby improving scalability and flexibility.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If mechanical pass-through connections are used, then data transfer between libraries is enabled, but magnetic tape cartridges are lost during export requiring compensation through imports

Engineering Contradiction:

Improvedata transfer efficiencyVSAvoidcartridge loss

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent replaces mechanical cartridge transport with electronic data transfer. Data is read from the source magnetic tape, transmitted electronically through the network, and written to the target magnetic tape. This eliminates physical cartridge movement and associated losses entirely, improving productivity while preventing substance loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Transferring data from a first data storage cartridge of a first data storage library to a second data storage library. The first library includes a first data storage drive, the second library includes a second data storage drive. If the first and second libraries are not connected by a mechanical pass-through, mounting the first data storage cartridge into the first data storage drive. A network connection between the first and second data storage drives, with both data storage drives operating in a data transfer mode, is initiated. Mounting a second data storage cartridge into the second data storage drive. Copying the data of the first data storage cartridge onto the second data storage cartridge via the network connection, and deleting the data of the first data storage cartridge. Else, transporting the data cartridge from the first library to the second library via the mechanical pass-through.
