Note the following about IB-FLEX:
You cannot mark an IB-FLEX appliance as a Grid Master or Grid Master Candidate with resources that are intended for small authoritative DNS, small recursive DNS (with acceleration), medium recursive DNS (with acceleration), and large recursive DNS (with acceleration). For more information, see

Infoblox recommends that you increase the memory to the following for IB-FLEX members to use certain features:
16 GB, instead of the standard 14 GB, to use DNS analytics.
20 GB, instead of the standard 18 GB, to use Threat analytics when RPZ is assigned to the IB-FLEX member.
- When using IB-FLEX-medium (or) IB-22X5 (physical/virtual) appliances with both Advanced DNS Protection and DNS Cache Acceleration enabled, the total appliance CPU usage goes up by ~10% higher than NIOS versions such as 8.5.1, 8.3.7, 8.3.6, and so on. This change is due to cores re-allocation as part of 8.5.2.
