  Traditional NAS storage architectures deploy simple two-way failover between two controllers in storage

  systems, such as highly available configurations.

  How is the Isilon architecture different in terms of system resiliency and availability?

  A. OneFS enables each node to have a designated partner node for simple failover between the pair.

  B. Use of client-side drivers can enable failover to other nodes.

  C. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
