General Information about BIG-IP Version 17.1.2.1
Summary
These release notes document the BIG-IP version 17.1.2.1 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:
- vCMP supported platforms
- VIPRION B2150, B2250
- VIPRION B4450 blade in the C4480 (J102) and C4800 (S100)
- BIG-IP 10350v, 12250v
- BIG-IP i5800, i7800, i10800, i11800, i15800
- PEM and CGNAT supported platforms
- VIPRION B2150, B2250, B4340N, B4450N
- PEM for BIG-IP iSeries: i5800, i7800, i10800, i11800, i15800
- CGNAT for BIG-IP iSeries: i2x00, i4x00, i5x00, i7x00, i10x00, i11x00, i15x00
- 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 vCMP guests.
- PEM is not supported on 8 GB platforms.
- BIG-IP i850 platform support
- The BIG-IP i850 platform supports Local Traffic Manager (LTM) only, and no other modules.
Memory: 12 GB or more
All licensable module-combinations may be run on platforms with 12 GB or more of memory, and on VE and vCMP guests provisioned with 12 GB or more of memory.
The BIG-IP license for the platform determines which combination of modules are available for provisioning.
Note: This does ensure that all modules may be simultaneously provisioned on all platforms with 12 GB or more of memory.
Memory: 8 GB
The following guidelines apply to VE guests configured with 8 GB of memory. (A vCMP guest provisioned with 8 GB of memory has less than 8 GB of memory actually available and thus does not fit in this category.)
- 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 and vCMP guests provisioned with less than 8 GB and more than 4 GB of memory. (A vCMP guest provisioned with 8 GB of memory has less than 8 GB of memory actually available and thus fits in this category.) 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 and vCMP only)
The following guidelines apply to VE and vCMP guests 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
vCMP memory provisioning calculations
The amount of memory provisioned to a vCMP guest is calculated using the following formula: (
platform_memory
- 3 GB) x (cpus_assigned_to_guest
/ total_cpus
).As an example, for the B2100 with two guests, provisioned memory calculates as: (16-3) x (2/4) ~= 6.5 GB.
For certain platforms, the vCMP host can allocate a single core to a vCMP guest. However, because a single-core guest has relatively small amounts of CPU resources and allocated memory, F5 supports only the following products or product combinations for a single-core guest:
- BIG-IP LTM standalone only
- BIG-IP GTM standalone only
- BIG-IP LTM and GTM combination only
