Q2 Single choice

A SQL Data Warehouse database is replicating between two VNX storage systems with Incremental San Copy. The production database is on 15, 15k rpm SAS drives and the Reserved LUN Pool uses five NL-SAS drives. The database is continuously updated locally and replicated once a day to maximize the benefits of write folding. Replication takes place from 6 PM until 10 PM. At 6 PM the storage administrator notices an increase in response time of the application, which steadily improves until 10 PM.

What should be done to improve performance during replication without affecting recovery data granularity?

  • A

    Put the Reserve LUN Pool on a similar disk and RAID type as the source volume.

  • B

    Create a clone of the source volume and replicate the clone.

  • C

    Expand the number of drives in the source volume to accommodate the increased I/O from the replication session.

  • D

    Adjust the San Copy throttle to minimize the impact to the production application.
