In an HPE 3PAR StoreServ system, the concept of a "node pair" is crucial to understanding how the system manages and owns physical drives. A node pair, which consists of two controller nodes, is responsible for managing the physical drives. Each node pair works in tandem to provide redundancy and high availability. The node pair owns the physical drives and manages data distribution, I/O operations, and redundancy across the drives within the system.

This architecture ensures that in the event of a failure in one node, the other node in the pair can continue to manage the drives and maintain data access, providing seamless operations and high reliability.

Object storage is best suited for unstructured data, such as images, videos, and backups, and it is characterized by the use of containers or buckets. Unlike traditional file storage systems, which use hierarchical structures like file systems, object storage uses a flat namespace and stores data as objects within these containers or buckets. This approach allows for scalability and easy management of large amounts of unstructured data, making it ideal for cloud storage and big data applications.

The correct action to optimize the storage configuration when adding new enclosures and drives to an existing HPE 3PAR StoreServ 8400 array is to run the tunesys command. This utility performs a system-wide optimization that includes rebalancing the data across all physical disks to ensure optimal performance and space utilization. tunesys is especially useful when new drives are added because it ensures that the workload is evenly distributed across both the new and existing drives, preventing potential hotspots and improving overall system efficiency. Defragmenting the Common Provisioning Groups (CPGs) and aligning the drives would be beneficial in certain scenarios, but the first and most comprehensive step is to use tunesys.
