QuestionQ37

Replication

What is one characteristic of SRDF/Metro?

  • A Data must be stored in cache on both sides before an acknowledgement is sent to the host.
  • B Multiple capture sets permit smaller cycles of data to be buffered on the R1 side and transferred to the R2 side.
  • C A dependent-write consistent copy is maintained between the R1 and R2 devices.
  • D Devices that have the Consistency Exempt attribute set can be controlled independently of the other devices.
Explanation

SRDF/Metro synchronously mirrors writes between R1 and R2 devices and resolves write conflicts to preserve consistent images across the paired devices. This maintains a dependent-write-consistent copy between the two sides.
