What is the minimum number of storage nodes that is supported at each site in a StorageGRID system?

In a StorageGRID system, the architecture is designed to provide high availability and data redundancy across multiple storage nodes. The minimum number of storage nodes supported at each site is three. This requirement ensures that the system can achieve sufficient fault tolerance and maintain data integrity even in the event of a node failure.

Having three storage nodes allows the system to use a quorum-based approach to manage data and achieve consistency. This configuration is crucial because it enables the system to continue functioning correctly in the event of one node becoming unavailable, ensuring that the data remains accessible and protected.

In contrast, a setup with only one or two nodes would not provide the necessary redundancy or reliability, as losing even a single node could lead to data unavailability or inconsistency. A minimum of four nodes is often part of larger configurations but is not the minimum required at each site. Therefore, three nodes strike a balance between operational efficiency and durability, making it the optimal choice for a single site within a StorageGRID deployment.
