The Sun QFS file system can be used in several different configurations:
Configured as a stand-alone file system on a single host
Configured as a shared file system, in which multiple hosts can write to and read from the file system
Configured as a multireader file system, in which only one host can write to the file system, but multiple hosts can read from the file system
Configured with the Sun Storage Archive Manager (SAM-QFS) product to support archiving features
Configured with the Oracle Solaris Cluster product for failover and high-availability
Unless otherwise noted, file system information throughout this document applies to archiving and non-archiving configurations.
The Sun QFS file system does not require changes to user programs or to the UNIX kernel.
