Note the following about IB-FLEX:
- An IB-FLEX instance must have a minimum of 6 cores and 14 GB memory to configure
You cannot mark an IB-FLEX appliance as a Grid Master or
aGrid Master Candidate
. When you do so, the IB-FLEX appliance is converted to Grid Managerwith 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 Table 8.8.
Infoblox recommends that you increase the memory to the following for IB-FLEX type 2 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.
