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.
