You are designing a small, direct attach storage solution for an existing HPE Proliant Server with HPE Smart
Array Controllers. Your customer asks you to provide full redundancy with no single point of failure.
What should you propose?

A.
dual-domain and dual-path SATA drives

B.
dual-domain and active SAS cables

C.
dual-domain and dual-port SAS drives

D.
dual-path and dual-port SCSI drives

Explanation:
Example: This dual-domain SAS architecture provides redundant pathways for cascaded JBODs. Using two IO
modules for each enclosure and SAS dual-port drives, this configuration provides redundancy throughout the
storage network and eliminates any single point of failure.
