3-1 Single and Dual Port Expanders
Single Ports
SC 933EL1 backplanes have a single-port expander that access all 16 drives and
supports cascading.
Dual Ports
SC 933EL2 backplanes have dual-port expanders that access all 16 drives. These
dual-port expanders support cascading, failover, and recovery.
