Benefits vs. complexity
A CFS gives users the option to cluster storage at the host, network or array level to share file access and maximize storage utilization. Each clustering architecture has its limitations (see "Clustered file-system architecture pros and cons," below), such as drive types or the need to install agents on hosts.
Assess your current storage environment and processing needs before jumping on the CFS bandwagon. Though the benefits may be substantial, you should also expect your storage environment to become more complicated and perhaps more difficult to manage.
