Dell EMC Exam D-PST-DY-23 Topic 1 Question 29 Discussion

IP Address Requirements for PowerStore T Appliances

Management IP: Each PowerStore T appliance requires one management IP address for initial configuration and ongoing management.

Cluster IP: Each PowerStore cluster requires one cluster IP address for internal communication between the appliances within the cluster.

File Mobility Network (FMN) IPs: For file replication, each PowerStore cluster needs three FMN IP addresses. These are dedicated IPs used for replication traffic between clusters.

Calculating the Total Number of IPs

Since the scenario involves two PowerStore T appliances in each cluster, let's calculate the IP addresses needed per cluster:

2 appliances x 1 management IP per appliance = 2 management IPs

1 cluster IP

3 FMN IPs

Total: 2 + 1 + 3 = 6 IPs

However, there's a crucial detail:

Additional IP for File Replication: When configuring file replication, an additional IP address is required on the source cluster for the destination cluster to connect to. This is used for the replication relationship and communication.

Therefore, the final count is:

Source Cluster: 6 IPs + 1 additional IP = 7 IPs

Target Cluster: 6 IPs = 6 IPs

Since the question asks for the minimum number of IPs in each cluster to complete the configuration, the answer is 7 IPs.
