What describes the SAS cabling when adding an expansion enclosure to a Dell EMC PowerStore,...

The correct description of the SAS cabling when adding an expansion enclosure to a Dell EMC PowerStore, for each node and expansion enclosure side, isOption D: SAS cabling goes from existing A ports to new B ports. At the last enclosure, SAS cabling returns from the A ports to the alternate node’s B ports.

When adding a SAS expansion enclosure to a Dell EMC PowerStore system, the cabling must be done in a specific manner to ensure proper connectivity and performance.

The SAS cabling should start from the existing A ports on the base enclosure and connect to the new B ports on the expansion enclosure1.

At the last expansion enclosure in the chain, the SAS cabling should return from the A ports back to the B ports on the alternate node1.

This cabling method ensures that each node is connected to each expansion enclosure and that the enclosures are daisy-chained correctly for optimal performance and redundancy1.

For detailed cabling instructions and diagrams, it is recommended to consult the Dell PowerStore Installation and Service Guide or contact Dell EMC support for assistance.
