BMC AMI Storage FATSCOPY

The architecture of BMC AMI Storage FATSCOPY is centered around its core components: the FATSCOPY engine, the FATS module, and the FATAR module. The FATSCOPY engine is the main program that orchestrates tape operations. The FATS (Fast Tape Stacking) module enables the stacking of multiple datasets onto a single tape volume, optimizing storage utilization.

The FATAR (Fast Tape Archive and Restore) module provides fast archive and restore capabilities. These components interact within the z/OS environment, utilizing z/OS system services for I/O operations and resource management. * **FATSCOPY Engine:** The central control component, responsible for managing tape copy, media conversion, and dataset stacking processes.

It handles JCL parsing, resource allocation, and error handling. * **FATS Module:** This module is responsible for stacking multiple datasets on a single tape volume. It ensures that datasets are written contiguously and that the tape volume is efficiently utilized.

The stacking process is transparent to applications and utilities. * **FATAR Module:** This module provides fast archive and restore capabilities. It allows for the efficient archiving of datasets to tape and the rapid restoration of datasets from tape.

Communication between these components occurs through internal z/OS system calls and data structures. There are no external APIs. The product relies on standard z/OS I/O protocols for tape device communication.

Configuration is managed through JCL, and security is handled through the z/OS security system (RACF or equivalent). Monitoring and logging are integrated with z/OS SMF records. Compared to standard z/OS utilities, FATSCOPY offers superior performance and advanced features like media conversion and dataset stacking.

The architecture is designed for high performance and efficient tape data management within the z/OS environment.
