BMC AMI Storage FDRERASE

The architecture of BMC AMI Storage FDRERASE is centered around the secure erasure of data on z/OS disk devices. The main components include the FDRERASE task, the data writing engine, and the verification module. The FDRERASE task is the primary control component, responsible for parsing commands, managing the erasure process, and interacting with the z/OS operating system.

The data writing engine handles the actual overwriting of data on the disk, using a specified pattern. The verification module ensures that the data has been successfully erased by comparing the written data with the erasure pattern. Communication between these components occurs through z/OS system calls and I/O operations.

The product uses direct disk I/O for data erasure, bypassing the file system to ensure complete data removal. The product does not use any databases or storage mechanisms other than the target disks. The product requires access to the disk devices and appropriate z/OS system privileges.

The administrative interface is primarily a command-line interface (CLI) for initiating and managing erasure tasks. The product supports RBAC for access control and provides audit trails for security. The product integrates with z/OS security features and offers logging of all erasure activities.

The product supports various disk types and offers customization of erasure patterns.
