It supports clusters consisting of multiple controller enclosures to improve the availability of the storage system

B.

Interconnect I/O modules shorten failover time when a controller fails to provide better reliability, as compared with common I/O modules.

C.

Standard I/O modules shorten failover time when a controller fails to provide better reliability, as compared with interconnect I/O modules.
