Question

You are designing a new Symmetrix VMAX storage array to replace a client's Symmetrix DMX4. Performance data is captured and examined for the DMX4. During the discovery phase, the client states that their critical business application has increased response times when establishing SRDF for 20 logical volumes. Examination of the current configuration of the logical volumes used for the application reveals the following:

  • Ten 4way meta volumes at 200 GB
  • Five 8 way meta volumes at 472 GB
  • Five logical volumes at 59 GB

Performance analysis shows that the device write pending counts for the five logical volumes at 59 GB are higher than other volumes used by the application. The client expects migration events to require a complete establishment of their DR environment logical volumes. How should all the devices be configured on the target Symmetrix VMAX storage array?

Options

  • AMeta volumes, minimum 3 members
  • BVirtual provisioned single volumes
  • CMeta volumes, minimum 4 members
  • DVirtual meta volumes, minimum 2 members
