FlexVM Licensing with Software NGFW Credits

Hi all,

As you probably know, paloalto recently changed the licensing of VM firewalls. With greater flexibility (and higher licensing costs), there is now also the possibility to increase only the RAM for such a VM firewall which results in higher capacity for rules, zones, concurrent sessions. Some of the specs which change with a different memory profile are written here: https://docs.paloaltonetworks.com/vm-series/10-0/vm-series-deployment/license-the-vm-series-firewall...


My question@ now are: are these the only specs that change with a different memory profile? What about concurrent dercypted sessions, virtual routers, ...? Does the vm refuse to boot if there is for example 20 GB of RAM attached or does the vm simply use the highes possible amount of RAM according to the memory profile?

Hi @istrydom 

Thanks for clarifying this with the Paloalto VM team. At least my question is now answered --> when the memory profile is increased also the maximum supported decrypted sessions will increase:

4.5 GB = 1'024 decrypted sessions

5.5 GB = 1'024 decrypted sessions

6.5 GB = 6'400 decrypted sessions

9 GB = 15'000 decrypted sessions

16 GB = 50'000 decrypted sessions

56 GB = 100'000 decrypted sessions

These sessions increase only by adding more RAM and it does not matter how many vCPUs you have licensed and added.

The virtual routers are tied to the vCPU count, so here you don't get more vrouters with more RAM.

Comparison Tool has spec for VMs

Here is example to compare 6 types of VMs

I can see there is difference in SSL Decryption section, Security Profiles, so on..







Hi @emr_1 

Thanks for your reply.

I saw that there are new options in the comparison tool, but so far these options actually are only the "old" vm-types (vm-100, vm-300, ...) with new names. My question is if only the RAM is increased. As shown in the link there are some specs which change if RAM is increased but what is about all the other specs which I mentionned (virtual router, concurrent decrypted sessions, ...)

Are you able to answer this prior to anyone in the community? 😉

An answer will probably also help others and not only me ...

@vsys_remo It loads the memory profile based on the memory assigned. Ex: if you assign 20G RAM, it will load 16G memory profile (one out of 6 profiles that we support)
