Preface

This manual, the Sun StorEdge QFS and Sun StorEdge SAM-FS File System Administration Guide, describes the file system software included in the Sun StorEdge QFS and Sun StorEdge SAM-FS 4.1 releases. The software products and the file systems they include are as follows:

Sun StorEdge SAM-FS file system. The Sun StorEdge SAM-FS environment includes a general-purpose file system along with the storage and archive manager, SAM. The Sun StorEdge SAM-FS environment's file system enables data to be archived to automated libraries at device-rated speeds. Data can also be archived to files in another file system through a process known as disk archiving. The file system in the Sun StorEdge SAM-FS environment is a complete file system. The user is presented with a standard file system interface and can read and write files as though they were all on primary disk storage.

Sun StorEdge QFS file system. The Sun StorEdge QFS file system can be used as a standalone file system, or it can be used in conjunction with the storage and archive manager, SAM. When used in conjunction with SAM, it is known as Sun SAM-QFS. Sun StorEdge QFS shares most of the Sun StorEdge SAM-FS file system's features. The Sun StorEdge QFS file system, however, is designed for high performance and contains more features than are supported within the Sun StorEdge SAM-FS environment.

Note - You can purchase licenses for both Sun StorEdge QFS and Sun StorEdge SAM-FS software with the intent to run the Sun StorEdge QFS file system with the storage and archive manager found in the Sun StorEdge SAM-FS software. Such a system is referred to as Sun SAM-QFS.

This manual does not call out the Sun SAM-QFS configuration unless it is necessary for clarity. In this manual, you can assume that references to Sun StorEdge SAM-FS also apply to Sun SAM-QFS configurations when talking about storage and archive management. Likewise, you can assume that references to Sun StorEdge QFS also apply to Sun SAM-QFS configurations when talking about file system design and capabilities.

The Sun StorEdge QFS and Sun StorEdge SAM-FS file systems are technologically similar, but within this manual, differences are noted when necessary.

The Sun StorEdge SAM-FS and Sun StorEdge SAM-FS 4.1 releases are supported on the following Sun Solaris trademark Operating System (OS) platforms:

Solaris 8, update 5, 7/01

Solaris 9, update 3, 4/03

This manual is written for system administrators responsible for installing, configuring, and maintaining Sun StorEdge QFS and Sun StorEdge SAM-FS file systems. You, the system administrator, are assumed to be knowledgeable about Solaris OS procedures, including installation, configuration, creating accounts, performing system backups, and other basic Solaris OS system administration tasks.
