Maximum Container Instances and Resources per Model

For each container instance, you can specify the number of CPU cores (or more specifically, threads) to assign to the instance. We use the term "core" generically to account for different hardware architecture. RAM is dynamically allocated according to the number of cores, and disk space is set to 40 GB per instance.

Software Requirements

You can run different versions of threat defense software on each instance as long as they are all compatible with the version of FXOS running on the chassis.

High Availability Requirements

  • The two instances in a High Availability configuration must:

    • Be on separate chassis.

    • Be on the same model.

    • Have the same interfaces assigned. All interfaces must be preconfigured in the chassis identically before you enable High Availability.

    • Use the same resource profile attributes. The profile names can be different, but the definitions need to match.

Management Center Requirements

For chassis management and all instances on the chassis, you must use the same management center due to the licensing implementation.
