Other VMware hypervisors are supported on a “Best Effort” basis: Cisco will try to help you, but it may not be possible to reproduce all problems, and Cisco cannot guarantee a solution.

Hardware Requirements for VMWare ESXi Deployments

Cisco UCS servers (blade or rack-mounted) are the only supported hardware platform.

Minimum requirements for the server hosting your virtual appliances:

Note

Except as explicitly stated in the documentation, Cisco does not support the alteration of the Cisco Content Security virtual appliance’s hardware configuration, such as removing IP interfaces or changing the appliance’s CPU cores or RAM size. The appliance may send alerts if such changes are made.


Note

VMWare ESXi 6.7 deployment is supported on Cisco UCS M4 and M5 chassis servers with AsyncOS 11.8.1-023 and later (for Web Security appliances).


Note

VMWare ESXi 7.0 deployment is supported on Cisco UCS M4 and M5 chassis servers with AsyncOS 14.0.1-053 and later (for Cisco Secure Web Appliances).

ESXi Drivers

Supported ESXi drivers:

  • Network Adapter Type: E1000
