Tiers are groups of node pools combined into a logical superset to optimize data storage, according to OneFS platform type. For example, similar ‘archive’ node pools are often consolidated into a single tier. This tier could incorporate different styles of H-series and A-series node pools into a single, logical container. This is a significant benefit because it allows customers who consistently purchase the highest capacity nodes available to consolidate various node styles within a single group, or tier, and manage them as one logical group.
The recommendation for large clusters is to configure no more than two tiers of storage.
