Sun StorEdge QFS and Sun StorEdge SAM-FS File System Administration Guide
|
|
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 4.2 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.
