A. A peer appliance can provide service while repairs are being performed.
B. Load balancing among multiple heads is allowed.
C. Clients are provided with a unified file system namespace across multiple appliances.
D. Rolling upgrade of software is allowed.

Explanation/Reference:
As an alternative to incurring hours or days of downtime while the head is repaired, clustering allows a peer appliance to provide service while repair or replacement is performed. Clusters support rolling upgrade of software, which can reduce the business disruption associated with migrating to newer software.
