A large data center uses a Cisco Nexus 9000 switch with FCoE NPV feature. The switch is connected to an MDS 9700 upstream. The network team recently replaced the MDS 9700 with a new one.

A large enterprise data center has a disaster recovery site 100 km away. The SAN uses two MDS 9700 series switches at each site, connected via a dedicated dark fiber. Each link operates at 16 Gbps with a round-trip time of 2 ms. Recently, backup jobs to the remote storage array have been failing with timeout errors.
