General Information about BIG-IP Version 21.0.0
Summary BIG-IP Version 21.0.0
These release notes document the BIG-IP version 21.0.0 release. You can apply the software upgrade to systems running software version 15.0.0 or later (except as detailed in the upgrading sections).
BIG-IP Virtual Edition (VE) is a version of the BIG-IP system that runs as a virtual machine. Supported modules include Local Traffic Manager, BIG-IP DNS, Advanced Web Application Firewall (Advanced WAF), Access Policy Manager, Policy Enforcement Manager, Application Firewall Manager, and Analytics. BIG-IP VE includes all features of device-based BIG-IP modules running on standard BIG-IP TMOS, except as noted in the release notes and product documentation.
The BIG-IP VE product license determines the maximum allowed throughput rate. To view this rate limit, you can display the licensing page within the BIG-IP Configuration utility.
Module combination and memory considerations
BIG-IP platform considerations
These platforms support various licensable combinations of product modules.
Most of the support guidelines relate to memory. The following list applies for all memory levels:
- PEM and CGNAT supported platforms
- BIG-IP Virtual Edition (VE) (Not including Amazon Web Service Virtual Edition) (3 GB, 10 GB production and combination lab models)
- PEM is not supported on 8 GB platforms.
Memory: 12 GB or more
All licensable module-combinations may be run on platforms with 12 GB or more of memory, and on VE provisioned with 12 GB or more of memory. Note that this does not mean that all modules may be simultaneously provisioned on all platforms with 12 GB or more of memory. The BIG-IP license for the platform determines which combination of modules are available for provisioning.
Memory: 8 GB
The following guidelines apply to VE guests configured with 8 GB of memory.
- No more than three modules should be provisioned together.
- To use Access Policy Manager (APM) and Secure Web Gateway (SWG) modules together on platforms with exactly 8 GB of memory, Local Traffic Manager (LTM) provisioning must be set to None.
Memory: Less than 8 GB and more than 4 GB
The following guidelines apply to platforms, and to VE provisioned with less than 8 GB and more than 4 GB of memory. Beginning in v14.x, 8 GB of memory is the very bare minimum to get three modules provisioned, suitable for a lab environment or very light production traffic, especially with a memory-intensive module such as AVR.
- No more than three modules (not including AVR) should be provisioned together.
- Analytics (AVR) counts towards the two module-combination limit (for platforms with less than 6.25 GB of memory).
In general, using 8 GB or fewer for later BIG-IP versions with memory-intensive modules might produce unexpected results.
Memory: 4 GB or less (VE only)
The following guidelines apply to VE provisioned with 4 GB or less of memory.
- No more than two modules may be configured together.
- Advanced WAF should not be provisioned, except as Dedicated
