Traditional NAS Storage Architecture Deploys Simple Two-Way Failover Between Two

Multiple Choice

Traditional NAS storage architecture deploys simple two-way failover between two controllers in their storage systems, such as highly-available configurations. How is the Isilon architecture different in terms of system resiliency and availability?

A) Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.
B) Isilon solutions can enable failover to other nodes with the use of client-side drivers.  
C) Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.  
D) Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.
