Network Design

A network engineer is operating a Cisco UCS environment connected to a Fibre Channel storage array. The Cisco UCS environment must connect to an existing SAN network, and several Cisco MDS 9000 Series Switches must be added to increase storage density. The solution must not exhaust the SAN network’s available domain IDs after the connection is made. In addition, most SAN traffic must be mapped from the Cisco UCS blades to a particular group of fabric interconnect ports. Which two features must be deployed to satisfy these requirements?

Choose two
  • A dynamic port pinning
  • B end host mode
  • C static PIN grouping
  • D N-Port ID virtualization
  • E priority flow control
Explanation

Cisco UCS end-host mode uses N-Port Virtualization behavior so the fabric interconnect functions as an edge host rather than joining the Fibre Channel fabric as a separate switch domain, conserving SAN domain IDs. Static SAN pin groups bind vHBA Fibre Channel traffic to designated fabric-interconnect uplink ports, providing the required deliberate traffic mapping.
