Also known as the Non-RAIN (Redundant Array of Independent Nodes) configuration. This is the entry levelconfiguration in which the single node acts as the utility node and the data storage node. When using thisconfiguration 2 single nodes are needed. 1 is the main backup node, and the 2nd is used for replicationpurposes for fault tolerance. Used in small to medium sized environments.

Muti-Node Non RAIN.

This is basically is a 3 node setup consisting of 1 Utility Node and 2 Data Storage Nodes. It allows for doublethe storage capacity of a Single Node device.

This configuration also needs a duplicate setup for replication, so a total of 6 Nodes would be needed for faulttolerance. Used in medium sized environments.

Multi-Node RAIN.

The Standard RAIN configuration has 1 Utility Node, 4 Data Storage Nodes and 1 Spare Node. Thisconfiguration can be expanded for a total of 16 Data Storage Nodes max. All of the nodes work together tobalance the storage equally across all of the other Data Storage Nodes. This architecture is easily scaled byadding as many Storage nodes as necessary. Typically used in large environments, this configuration can beinitially setup with 3 Storage nodes instead of the standard 4 Storage nodes. It is recommended to setup aduplicate Multi-Node RAIN for replication, typically at a DR site. Although it is recommended, it is not anecessity like the Non-RAIN configurations, because there is a spare node that can be configured at any pointfor fault tolerance.
