Hi, As per M-500 physical appliance specification Processor Intel Xeon 6-core CPU Memory/Internal Storage 128GB DDR4 RAM/240GB SSD storage Storage Up to 24TB storage for logs; default is 4TB So you can configure Panorama to function in one of several different modes: •A physical Panorama appliance (such as an M-500) can operate in: •Panorama mode – firewall management and log collection •Log Collector mode – dedicated log collector only •Management Only mode – firewall management only without log collection capabilities •The Panorama virtual appliance can function in one of four different modes: •Panorama mode – firewall management and log collection •Log Collector mode – dedicated log collector only •Management Only mode – firewall management only without log collection capabilities •Legacy mode The default mode for both virtual appliances and for M-Series appliances is Panorama mode. Legacy mode is a transitional option to help customers upgrade from older Panorama versions (such as version 7). The legacy mode does not support any of the logging and reporting enhancements made since Panorama 8.0. Legacy mode is available only when you have an existing Panorama 8.0 virtual appliance running in Legacy mode and you upgrade that device to 8.1. You can change a Panorama virtual appliance from Legacy mode to one of the other options; however, once you make the change you cannot revert the appliance to Legacy mode. On a fresh install of 8.1 and later versions, Legacy mode no longer is available. You can change Panorama from one mode to another if the following resource requirements are met: System Mode Minimum Resource Requirements Maximum Log Storage Capacity Panorama 16 CPUs, 32GB RAM 24TB Log Collector 16 CPUs, 32GB RAM 24TB Management Only 16 CPUs, 32GB RAM. And many enterprises have moved to the public cloud to reduce cost and simplify the management efforts of their applications and services. With this move, enterprises can avoid the need to deploy an on-premises M-Series Panorama to manage their VM-Series firewalls in public cloud environments. Now you can deploy the entire Panorama solution on an M-Series appliance, in a public cloud, on a hypervisor such as ESXi, or a combination, depending on your requirements. A Panorama virtual appliance deployed in a public cloud offering can manage firewalls inside and outside the cloud. Likewise, a Panorama physical appliance can manage physical firewalls as well as virtual firewalls in public and private clouds Best Regards, Suresh
