VxFS Functionality on Cluster File Systems
8 Installation and Administration Guide
Using CFS on File Servers
Two or more servers connected in a cluster configuration (that is, connected to the same
clients and the same storage) serve separate file systems. If one of the servers fails, the
other recognizes the failure, recovers, assumes the primaryship, and begins responding to
clients using the failed server’s IP addresses.
Using CFS on Web Servers
Web servers are particularly suitable to shared clustering because their application is
typically read-only. Moreover, with a client load balancing front end, a Web server
cluster’s capacity can be expanded by adding a server and another copy of the site. A
CFS-based cluster greatly simplifies scaling and administration for this type of
application.
