A platform engineer is tasked with adding F600 nodes to an existing Dell EMC PowerScale cluster. After racking and stacking the F600 nodes, they determine that the cluster contains X210 and H400 nodes.

What should the platform engineer consider?

A.

H400 nodes cannot co-exist with the F600 nodes in the same cluster

Answers
A.

H400 nodes cannot co-exist with the F600 nodes in the same cluster

B.

The F600 must use InfiniBand for internal network communication

Answers
B.

The F600 must use InfiniBand for internal network communication

C.

F600 nodes cannot co-exist with X210 nodes in the same cluster

Answers
C.

F600 nodes cannot co-exist with X210 nodes in the same cluster

D.

The cluster must be upgraded to Ethernet back-end topology

Answers
D.

The cluster must be upgraded to Ethernet back-end topology

Suggested answer: D

Explanation:

Adding F600 nodes to an existing cluster requires compatibility in back-end networking.

Key Considerations:

Back-End Networking:

F600 Nodes: Use Ethernet for internal communication.

Existing Nodes (X210 and H400): May be using InfiniBand.

Action Required:

Upgrade the cluster's back-end to Ethernet topology to accommodate F600 nodes.

Why Other Options Are Incorrect:

Option A: H400 nodes can coexist with F600 nodes if back-end networking is compatible.

Option B: F600 nodes do not use InfiniBand.

Option C: F600 nodes can coexist with X210 nodes with the appropriate back-end network.
