How is volume access control configured by the NetApp Deployment Engine (NDE)?

The correct approach to configuring volume access control by the NetApp Deployment Engine (NDE) involves creating an initiator for each compute node. This setup allows the NDE to properly manage and control access to storage resources based on the specific initiators associated with each compute node. By assigning initiators to compute nodes, NDE ensures that only designated nodes can access specific volumes, enhancing security and control over data storage.

In contrast, assigning a volume to a single initiator might overly restrict access and reduce flexibility in how resources are utilized across multiple compute nodes. Automatically granting access to all users lacks the necessary granularity and control, which can lead to potential security issues. Adding initiators to a universal access group may not provide the specificity needed for managing access on a per-volume basis, potentially allowing more access than intended. Thus, the first method, creating an initiator for each compute node, is the most effective way to maintain appropriate volume access control.
