You are preparing to install a new 2-node AFF A250 system at a site with an existing cluster using NetApp CN1610 interconnect switches. Which two valid actions are applicable?

You are preparing to install a new 2-node AFF A250 system at a site with an existing cluster using NetApp CN1610 interconnect switches. Which two valid actions are applicable?

• A. Create a new 2-node switchless cluster.
• B. Migrate the existing cluster to new switches and add the new nodes.
• C. Create a new 2-node switchless cluster and migrate the existing cluster to new switches and add the new nodes.
• D. Do nothing

Answer: (C)

Switchless operation for a two-node AFF cluster is supported, so you can bring in the new A250 pair without immediately tying it into the existing switch fabric. By creating a new 2-node switchless cluster, you get the new hardware up and running quickly while you plan the interconnect topology. At the same time, you can migrate the existing cluster to refreshed CN1610 switches and then add the new nodes into that migrated cluster. This approach minimizes disruption, uses supported deployment modes for both old and new hardware, and ultimately brings all nodes under one operational cluster as needed. Do nothing isn’t appropriate because you’re expected to add new hardware and evaluate interconnect options. Creating only a new switchless cluster would leave the existing cluster untouched, and migrating only the old cluster without adding the new nodes wouldn’t incorporate the new hardware.
