A platform engineer is building a new Dell EMC PowerScale cluster. The configuration wizard prompts to configure int-a.

What is a consideration when configuring int-a?

A.

Must be on the same subnet as int-b.

Answers
A.

Must be on the same subnet as int-b.

B.

Must use the same subnet as groupnet0, subnet0.

Answers
B.

Must use the same subnet as groupnet0, subnet0.

C.

Must be on a separate subnet from int-b.

Answers
C.

Must be on a separate subnet from int-b.

D.

Must use the same subnet as node 1, ext-1.

Answers
D.

Must use the same subnet as node 1, ext-1.

Suggested answer: C

Explanation:

In a Dell EMC PowerScale cluster, int-a and int-b are internal network interfaces used for back-end communication between nodes. Proper configuration of these interfaces is essential for cluster performance and redundancy.

Considerations:

Separate Subnets for int-a and int-b:

Assigning int-a and int-b to separate subnets enhances network redundancy.

If one subnet experiences issues, the other can continue to handle internal traffic.

Not on the Same Subnet:

Placing both interfaces on the same subnet can create a single point of failure.

It may also cause network conflicts and degrade performance.

Key Points:

Network Isolation: Separating int-a and int-b ensures that internal communications are robust and fault-tolerant.

Performance Optimization: This configuration allows for load balancing of internal traffic.

Reference:

Dell EMC PowerScale OneFS Network Configuration Guide:

Internal Network Configuration section recommends using separate subnets for int-a and int-b.

Explains the benefits of network redundancy and performance.

Best Practices:

Plan IP addressing schemes that allocate different subnets for internal interfaces.

Document network configurations for troubleshooting and maintenance.
