Storage Network Design

A customer connects a high-speed Fibre Channel storage array to a Cisco MDS 9000 Series Switch through an 8-Gbps interface.

Which action ensures line-rate traffic processing on the interface?

  • A Set global buffering with B2B_credits for the interface.
  • B Set local buffering with B2B_credits for the interface.
  • C Configure the interface rate mode as dedicated.
  • D Configure the interface rate mode as shared.
Explanation

Dedicated rate mode allocates the fabric bandwidth and associated resources required to sustain line-rate traffic at the port’s configured maximum operating speed. Shared rate mode shares those resources, while B2B credits control Fibre Channel buffer-to-buffer flow control rather than reserving line-rate fabric capacity.
