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.

D.
OneFS enables each node to be a peer to any other node in an Isilon cluster. Any node
can take over for any other node.
