NS0-194: NetApp Certified Support Engineer

The workload latency is dominated by network latency, while disk latency is zero and the other ONTAP subsystem latencies are negligible. The network path should therefore be checked at the network interface card and the cluster switches. NetApp documents that the Network field reports latency in the network subsystem.

NDMP supports backup application integration for backing up NetApp data to tape, providing physical media that can be stored off site for regulatory retention requirements.

The NetApp DS4246 disk shelf provides 24 drive bays, with bays numbered 0 through 23.

CRC errors commonly result from a physical media-path fault, including a poorly seated or failed SFP and a damaged or improperly seated cable. Reseating or replacing those components is therefore appropriate before treating the node’s physical port as faulty.

NetApp HCI compute nodes support two-cable and six-cable network configurations. The two-cable topology carries the required traffic on two bonded ports, while the six-cable topology uses dedicated port pairs for traffic types. A four-cable topology is for storage nodes, not compute nodes. NetApp: Select a network topology
