E.

Answers
E.
The storage rote and hosts role must be configured to the same target IP addresses
Suggested answer: A, C, D

Explanation:

To configure Storage Data Targets (SDTs) for I/O operations with hosts using the NVMe over Fabric protocol, the following requirements are necessary:

The Storage port must be configured with the host role: The storage port, which is part of the SDT, needs to be configured to communicate with the host systems.This involves setting the port to operate in the host role, which allows it to handle input/output operations with the hosts1.

The NVMe Qualified Name (NQN) of the hosts is known: The NQN is a unique identifier used in NVMe over Fabrics to identify both NVMe targets and hosts.Knowing the NQN of the hosts is essential for proper configuration and communication between the SDTs and the hosts1.

A minimum of two NVMe targets must be assigned to a Protection Domain: For redundancy and to ensure continuous availability, it is recommended to have at least two NVMe targets assigned to a Protection Domain.This allows for failover capabilities and load balancing across multiple paths1.

These requirements are based on the best practices for setting up NVMe over Fabric protocols as outlined in the PowerFlex documentation and resources.Proper configuration of the storage ports, knowledge of the NQN, and assignment of NVMe targets to a Protection Domain are crucial steps in ensuring successful I/O operations with NVMe over Fabrics1.
