QuestionQ86

Storage Network Design

Refer to the exhibit.

Question Image

Server 1 cannot connect to the storage array through the Storage Area Network (SAN) of the Cisco MDS 9000 Series Switch. The storage network must be redesigned while considering these requirements:

  • Traffic from every server must be redundant and isolated.
  • The design must withstand hardware and software failures, as well as upgrades, of SAN fabric devices.

Which action must be taken to satisfy these requirements?

  • A Enable NPV and F-Port-channel on ports that face Server 1 on the Fibre Channel switch to create redundant paths.
  • B Create a SAN port channel that faces the storage device to sustain a link failure.
  • C Add an additional supervisor to the Fibre Channel switch to support nondisruptive upgrades.
  • D Place an additional Fibre Channel switch to create two physically independent storage fabrics.
Explanation

A dual-fabric SAN built with an additional Fibre Channel switch eliminates the existing single-switch failure domain. Connecting each server and the storage array to both physically independent fabrics provides redundant paths while keeping the fabrics isolated, so an outage or upgrade in one fabric does not disrupt access through the other.
