• Question 44:

  A company has merged its two existing SANs that were in adjacent buildings. The data center in each location had been utilizing at least half of its total SAN bandwidth. Now they now plan to migrate all production data to one data center and replicate that data across the new ISLs to the other data center which will now only be used for for disaster recovery purposes. What is the potential impact to performance after completing this reconfiguration?

  A. no change to SAN performance

  B. increased performance for production traffic

  C. decreased performance for production traffic

  D. ISL oversubscription will determine performance

  Correct Answer: C
