As you define SmartConnect subnets and pools, it is important to understand the SmartConnect hierarchy, as displayed in the following figure:
Throughout the network design phase, for releases prior to OneFS 8.2, consider that a single SSIP is defined per subnet. However, under each subnet, pools are defined, and each pool has a unique SmartConnect zone name. Recognize that multiple pools lead to multiple SmartConnect zones using a single SSIP. As shown in the preceding figure, a DNS provider is defined per groupnet, which is a feature in OneFS 8.0 and later releases. In releases earlier than 8.0, a DNS per groupnet was not supported.
OneFS 8.2 introduces support for multiple SSIPs per subnet, as displayed in the following figure:
