Storage

Welcome to ADM

Automatic Data Migration (ADM) is a hierarchical storage management system for Sun filesystems. ADM provides several key functions.

• Capture file data to archive storage (tape or disk), and preemptively releasing data blocks in order to keep applications from running out of disk space.
• Recall of released data from archive storage, when needed.
• Capture, release and recall data to/from archive storage based on policies established by the administrator based on file characteristics.

ADM will initially integrate with ZFS, supplying file archiving, releasing (freeing up filesystem blocks associated with a file), and automatic retreival based on access. The ADM/ZFS project provides some of the functional characteristics provided by todays SAM-QFS, but could be ported to other filesystems as well. ADM is intended to scale beyond existing HSM systems in the number of files, size of files and amount of back end storage. This is accomplished by enabling major functions of the HSM system to be distributed between different nodes in the system, or duplicate nodes.

ADM Features

• Policy Management of files, including classification
• Data protection (archiving) as many copies of a file as needed
• ZFS level scalability
• Disk archiving support
• STK tape and library support via the Media Management System (MMS)
• Simplified administration model

For a more detailed look at these features, and more, check out What is ADM? page.
