Overview
Find details about the system requirements for deploying Cisco Secure Firewall Management Center Virtual (FMCv) on Nutanix AHV, including required CPU, RAM, disk space, network interfaces, supported drivers, and important recommendations to avoid resource allocation issues and ensure optimal virtual appliance performance.
We recommend you do not decrease the default settings: 32 GB RAM for most the Firewall Management Center Virtual instances. To improve performance, you can always increase a virtual appliance’s memory and number of CPUs, depending on your available resources.
Memory and Resource Requirements
-
You can run multiple virtual machines running unmodified OS images using Nutanix AHV. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, and so forth. See the Cisco Secure Firewall Threat Defense Compatibility Guide for hypervisor compatibility.
-
Check for the latest Release Notes for details on whether a new release affects your environment. You may be required to increase resources to deploy the latest version.
-
The specific hardware used for the Firewall Management Center Virtual deployments can vary, depending on the number of instances deployed and usage requirements. Each virtual appliance you create requires a minimum resource allocation—memory, number of CPUs, and disk space—on the host machine.
-
The following lists the recommended and default settings for the Firewall Management Center Virtual appliance on Nutanix AHV:
-
