You are preparing to install a new 2-node AFF A250 system at a customer site with an existing cluster that uses NetApp CN1610 cluster interconnect switches.
In this scenario, what are two valid actions for this installation? (Choose two.)
You are preparing to install a new 2-node AFF A250 system at a customer site with an existing cluster that uses NetApp CN1610 cluster interconnect switches.
In this scenario, what are two valid actions for this installation? (Choose two.)
The AFF A250 system uses 25GbE ports for cluster interconnect, while the CN1610 switches use 10GbE ports, making them incompatible. Therefore, adding the new nodes to the existing CN1610 switches or creating a new cluster using these switches is not viable. The valid actions for the installation are to either create a new 2-node switchless cluster or migrate the existing cluster to new switches that support 25GbE and then add the new nodes.
Should be C and D , must not B Because AFF A250 not supported with CN1610 switches Reference: https://kb.netapp.com/Advice_and_Troubleshooting/Flash_Storage/AFF_Series/Controller_Hardware_Upgrade%3A_Adding_AFF_A250_nodes_to_existing_cluster_report_HA_interconnect_errors_and_cannot_perform_takeover
CN1610 switch uses 10GbE ports. A250 cluster ports e0c and e0d are 25GbE ports so CN1610 not usable. Answer definitely C,D
AFF A250 not supported with CN1610 switches
A250 cluster ports e0c and e0d are 25GbE
CN1610 is 10G only while A250 ist 25G only, so they are not compatible
