• Question 15:

  A company is evaluating the deployment of SRDF/Star on VMAX3 arrays. One of the concerns is that the SRDF daemon represents a single point of failure. How could this concern be addressed?

  A. RDF daemon process runs on the embedded Tools Virtual Machines and has built-in high availability.
  B. Run RDF daemons on multiple management stations at the workload site. RDF daemons will cooperate with each other.
